There are 6 objects in the model that have various relationships - it was neat, it took like 20 minutes! Now that I have it, I want to create Spring MVC project and use the domain model - but I want to keep the web project totally separate from the Roo project (I don't understand Spring MVC to use the scaffolding in Roo yet).
So I've created the dependency in the pom.xml of the web project and I can build and deploy the web project using 'mvn tomcat:run'. However, when the web tries to use the Spring Roo objects I get exceptions like this:

This being Spring MVC I sort of assumed it was happening automagically - I am obviously mistaken.
So do I need to do something in the web project to get the context loaded for the Roo jar file? Or do I need to change something in the roo jar file project? Do I need annotate a controller with something to make this happy?

I have a class `User` that needs to do some DB operations (using the class `DB`). The controllers create `DB` as appropriate, and inject it into `User` with its constructor.
When a user is logged in, a `User` object is stored to the session. The problem is that `DB` cannot be serialized to the session, so when `User` wakes up, its `db` member is `null`, which is bad. I solved this pretty simply with
public function __wakeup() { $this->db = new DB; }
..however, this is definitely a violation of DI, and it could even cause problems down the line if the `DB` needs to be different depending on the controller (the controller creates the `DB` it needs, after all).
Problem is that when `User` is unserialized from the session, it's not constructed again, so it doesn't have a chance to get the DB member. I have several possible solutions, and the problems each has:
* Allow DB to be set by setter injection
* This also doesn't seem like a great solution. It also opens up the possibility of setting the `DB` at an inappropriate time, and still seems to violate the DI spirit. The controller also has to know to set the `DB`
* Don't serialize the object, but serialize a token and recreate the object every time
* This would be inconvenient and seems inefficient. This could also lead to some repetition (each controller would need to do something like `$usr = new User($_SESSION['user-token'], new DB);`). On the other hand, keeping the `User` object out of superglobals would dissuade some nasty global variable usage.

For example let's take a string which spans two rows and has control characters (\r \n " / \\) in it:
<?php
$s = <<<END
First row.
Second row w/ "double quotes" and backslash: \.
END;
echo json_encode($s);
// Will output: "First row.\r\nSecond row w\/ \"double quotes\" and backslash: \\."

Note that carriage return and newline chars are unescaped. Why?
I'm using jQuery as my JS library and it's $.getJSON() function will do fine when you fully, 100% trust incoming data. Otherwise I use JSON.org's library json2.js like everybody else.
But if you try to parse that encoded string it throws an error:
<script type="text/javascript">
JSON.parse('<?php echo $s ?>'); // Will throw SyntaxError
</script>
And you can't get the data! If you remove or escape \r \n " and \ in that string then JSON.parse() will not throw error.
Is there any existing, good PHP function for escaping control characters. Simple str_replace with search and replace arrays will not work.

We have been developing enterprise applications for many years based on Oracle technologies, right now we have reached a significant number of systems developed with Oracle Forms 6i and a few ones in Oracle Forms 10g. For many obvious reasons we have realized we have to move forward and a need has emerged for a replacement of our development platform, although we will keep using the Oracle database. A key requirement in every technology we have evaluated has been the capability of developing Rich Internet Applications, or at least traditional Web Applications, it must run on mobile devices such as the iPad, and must has support for the cloud. After an eliminating process we considered two options:
1. Oracle solution: The first option we considered was Oracle ADF, JDeveloper, Java and Oracle WebLogic Server. The principal disadvantage of this alternative was the licensing cost of WebLogic Server and the lack of a reporting tool within the IDE, plus a few other maybe subjective things about the IDE. A 100% Oracle solution would include BI Publisher as the Oracle official reporting tool, but the funds for its acquisition are unlikely to be approved. A 100% Java solution would include JasperReports for reporting, but still we consider the price we are going to pay to Oracle is too high for not including a reporting solution.
2. Microsoft solution: The second option we considered was Microsoft Silverlight, Visual Studio, C# and Internet Information Services. This alternative seems very attractive regarding the cost compared to Oracle WebLogic, but little research was necessary to find out that everyone seems to agree that Microsoft won’t launch any more releases of Silverlight after version 5 and I perceive a feeling of uncertainty about the future in the Microsoft developer community regarding Silverlight and the Windows 8 new approaches: Metro Style Apps, HTML5, etc. We are not advocating Windows Forms since I don’t see any future for this platform in the cloud era, and ASP.NET doesn’t seem to be suitable for large, complex enterprise applications needing to handle high volumes of data.
This way, any suggestions, ideas, recommendations, considerations or advices you can give us about a development platform for developing next generation enterprise applications, would be welcome and really appreciated. If I’m wrong in any of the above please correct me. Thank you very much to all of you for reading this and thank you in advance for your answers.

I have a List with a custom ItemRenderer which is bound to cueArray. The ItemRenderer has two buttons, Complete and Cancel. When cancel is clicked, the particular cueItem.state variable (called by changing the data.state inside the ItemRenderer) is changed from 'cued' to 'cancelled'. An eventListener on cueArray then triggers a changeEvent that updates the data with RemoteObject and then removes the clicked cueItem object from cueArray.
The trick is that if the RemoteObject call fails (because of a broken connection) the state should be changed back to 'cued' and the item should not be removed from cueArray. If the result event handler is called, the item should be removed from cueArray.
The problem is that in the Result and Fault event handlers, I do not have access to which cueArray item was clicked. I realise that there are workarounds, but I am looking for a graceful solution. For instance, in the Result event handler I can have my php function return the ID of the cueItem that was changed, but that does not solve my problem with the Fault handler.
Do you have any ideas?

I am using PRISM, and my objects are created by a DI container. Lets assume the following simple scenario:
I have an object workflow. This workflow has several properties, and there is a WorkflowProvider which provides a list of workflows.
If I design the ListView I do not have a problem. I am using a MainApplication object as design time data context, and my list binds to the property "WorkflowList". In my live application I can set the data context to the appropriate implementation.
But I do not know how to handle a **single workflow view**!
Normally I would create a **workflow object as design time data context**. But my workflow object can't be created on its own (with an empty constructor), it has to be a property of e.g. my WorkflowProvider. So one approach I used in the past was this:
- Write a dummy subclass for workflow
- In the empty constructor of the dummy, get the "real workflow"
- Assign all properties of the "real workflow" to the properties of my dummy class
- Use an instance of the dummy workflow in my design time view
The only reason for that is that I do not know how to set the design time data context to a property, instead of an object. Is this possible, or is there any other way which makes sense. To clarify, I know I could bind e.g. my grid in my "workflow details view" to a property, but then I could not use the details view without changes as a DataTemplate in my list view. I hope you got my problem :-)

This is further confusing to me when I also consider that in the same program I can call the following function in an ostensibly correct way and in another incorrect way, and I get the same behaviour, though in contrast to what happened in the code posted above!?
working_on_pointers ( pFarr, farr ); // calling with expected parameters

We’d like to provide clean and simple user experience similar to DropBox but we’d prefer not to develop it ourselves. Email is not an option. Our default would be to just implement our own browser-based AFAX file upload and develop the backend ourselves, but this strikes me as re-inventing the wheel.
The main issue is that we need to support a many-to-one uploading model: 1000s of users, each with their own private folder, uploading files to be shared with us. I have been looking at file sharing services and most seem to be focused on a push / publish model, i.e. enabling end users that want to share their files. We’re looking for a solution that is more of a pull model, i.e. enabling us to ask users to agree to send us some data, and then once they’ve done so, making it trivially easy for them to send us the files e.g. via a short-lived drop box with a clean upload UX. I think what we might need is something like an a server-side framework, libraries, and/or SaaS hosted file sharing service that gives us:
- Easy management of user-specific drop boxes (e.g. setting them up w
expiry dates, sending email invites, etc)
- Easy UI for upload: either
desktop integration (like DropBox) or a modern AJAX UI (drag files
into the browser)
- Good end user UX (progress bars, option to restart
upload, etc)
- No additional accounts: users can either use existing
authentication credentials from our site (e.g. via SSO) or can use a
one-time encrypted URL to get access to an upload folder. Users
should not need to create an account anywhere, nor need to figure out
how to set up folder sharing. Branded using our brand (vs a 3rd
party)
- Strong security
- A business model compatible with this scenario (e.g. priced per server or per GB transferred, not per user)
In addition, it would be cool to have things like:
- Email invitations to one-time web-based “drop boxes”, optionally with an expiration
- Notifications sent to us when an end-user invitation has been used / users have uploaded files
- Optionally backable by Amazon S3 or some similar scalable store
Can anyone suggest existing libraries and/or services that might solve part of this for us?

We’d like to provide clean and simple user experience similar to DropBox but we’d prefer not to develop it ourselves. Email is not an option. Our default would be to just implement our own browser-based AFAX file upload and develop the backend ourselves, but this strikes me as re-inventing the wheel.
The main issue is that we need to support a many-to-one uploading model: 1000s of users, each with their own private folder, uploading files to be shared with us. I have been looking at file sharing services and most seem to be focused on a push / publish model, i.e. enabling end users that want to share their files. We’re looking for a solution that is more of a pull model, i.e. enabling us to ask users to agree to send us some data, and then once they’ve done so, making it trivially easy for them to send us the files e.g. via a short-lived drop box with a clean upload UX. I think what we might need is something like an a server-side framework, libraries, and/or SaaS hosted file sharing service that gives us:
- Easy management of user-specific drop boxes (e.g. setting them up w
expiry dates, sending email invites, etc)
- Easy UI for upload: either
desktop integration (like DropBox) or a modern AJAX UI (drag files
into the browser)
- Good end user UX (progress bars, option to restart
upload, etc)
- No additional accounts: users can either use existing
authentication credentials from our site (e.g. via SSO) or can use a
one-time encrypted URL to get access to an upload folder. Users
should not need to create an account anywhere, nor need to figure out
how to set up folder sharing. Branded using our brand (vs a 3rd
party)
- Strong security
- A business model compatible with this scenario (e.g. priced per server or per GB transferred, not per user)
In addition, it would be cool to have things like:
- Email invitations to one-time web-based “drop boxes”, optionally with an expiration
- Notifications sent to us when an end-user invitation has been used / users have uploaded files
- Optionally backable by Amazon S3 or some similar scalable store
Can anyone suggest existing libraries and/or services that might solve part of this for us?

I have an object with a number of properties (let's say object.one, object.two, object.three). There are about 30 of these properties and they all hold a string ("Pass" or "Fail").
Right now the existing code checks whether the property has value "Pass" or "Fail" and then runs some code that prints stuff out. That is, the same snippet of code is duplicated 30 times, one for each of these properties.
The code looks something like this
If (object.one = ... )<br/>
...<br>
End if<br>
If (object.two = ... )<br>
...<br>
End if<br>
If (object.three = ... )<br>
...<br>
End if
I want to use a loop to clean this mess up (each block is huge), but am not sure how to do it. I was thinking perhaps there was a way such that I might be able to construct a string like "object.one" and run some function that will tell the compiler that this is actually an object's property?
That way I could create an array containing the object's name like my array = {"object.one", "object.two", "object.three"} and then do something like, in pseudocode
For each string in my array<br>
If (some_function(string) = ...)<br>
...<br>
End If
Essentially, it would take those massive blocks of duplicated code and reduce it to just one block. Is there such a some_function that I am looking for?

It seems easier to just use the include files of the library, and just link precompiled binaries to my application. So my question is this. Is it better for me to include the source code of each library to my project, compile and link, or will it be better to just compile the libraries separately (or download a precompiled version) and link it to my program?

I have a user application that needs to determine if a particular process is running. Here's what I know about the process:
- The name
- The user (`root`)
- It *should* already be running, since it's a LaunchDaemon, which means
- Its parent process should be `launchd` (pid 1)
I've tried several ways to get this, but none have worked so far. Here's what I've tried:
1. Running `ps` and parsing the output. This works, but it's slow (`fork`/`exec` is expensive), and I'd like this to be as fast as possible.
2. Using the `GetBSDProcessList` function [listed here][qa1123]. This also works, but the way in which they say to retrieve the process name (accessing `kp_proc.p_comm` from each `kinfo_proc` structure) is flawed. The resulting `char*` only contains the first 16 characters of the process name, which can be seen in the definition of the `kp_proc` structure:
<pre>#define MAXCOMLEN 16 //defined in param.h
struct extern_proc { //defined in proc.h
...snip...
char p_comm[MAXCOMLEN+1];
...snip...
};</pre>
3. Using [libProc.h][libproc] to retrieve process information:
<pre>pid_t pids[1024];
int numberOfProcesses = proc_listpids(PROC_ALL_PIDS, 0, NULL, 0);
proc_listpids(PROC_ALL_PIDS, 0, pids, sizeof(pids));
for (int i = 0; i < numberOfProcesses; ++i) {
if (pids[i] == 0) { continue; }
char name[1024];
proc_name(pids[i], name, sizeof(name));
printf("Found process: %s\n", name);
}</pre>
This works, except it has the same flaw as `GetBSDProcessList`. Only the first portion of the process name is returned.
4. Using the [ProcessManager function][pm] in Carbon:
<pre>ProcessSerialNumber psn;
psn.lowLongOfPSN = kNoProcess;
psn.highLongOfPSN = 0;
while (GetNextProcess(&psn) == noErr) {
CFStringRef procName = NULL;
if (CopyProcessName(&psn, &procName) == noErr) {
NSLog(@"Found process: %@", (NSString *)procName);
}
CFRelease(procName);
}</pre>
This does not work. It only returns process that are registered with the WindowServer (or something like that). In other words, it only returns apps with UIs, and only for the current user.
5. I can't use [`-[NSWorkspace launchedApplications]`][nsws], since this must be 10.5-compatible.
I know that it's *possible* to retrieve the name of running processes (since `ps` can do it), but the question is "Can I do it without forking and exec'ing `ps`?".
Any suggestions?

It "feels" like a cache issue of some sort but a hard refresh doesn't do anything. Here is an example. The video header is where a video should be outputting.

However, my program crashes during the invocation of the block, leaving only an `EXC_BAD_ACCESS` in its trail.
My program uses a framework built agains the Mac OS 10.5 SDK that does not support garbage collection (nor 64 bits) and the MacFUSE framework. The program builds with no warning or error as a 32-bit program. Other build settings (such as optimization level) were left to their original values.

`runWithContinuation:` retains the block and instantiates a nib. The block is called only once the user dismisses the password prompt by pressing the "Open" button.

You can just read the question. Feel free to read the examples if you are not sure of what I'm asking.***
**QUESTION:**
A programmer will have a job where he will need to create a wide range of applications of unrelated problems, possibly problems that are completely new to the programmer, possibly with multiple requeriments (ex: databases+3d graphics+networking), in the least time possible counting from the instant he is asked to do so. Those applications doesn't need to be optimized but they need to be optimizable if required. What tools/languages/libraries should he learn?
**EXAMPLES:**
For instance that person would/could need:
- True object oriented base (I think that is the name) - he needs to, for instance: get all instances of a class calling Class.instances, modify a Class in runtime - also, retrieve a reference to the Class object of a instance calling instance.type and being able to compare between classes like:
*myBird.type.isChildrenOf(Animal) //compares if type of myBird instance is inherited from Animal*. Other features like keeping track of past states of instances, for instance,
*if (last(pos)=[3,0,0]) then //checks if last state of vector pos was [3,0,0]*
and automatically synchronizing instances between different applications, for instance,
*game = create Game; //creates instance of class Game
game.syncronize("www.mygame.com",51320); //syncronizes "game" instance to that hosted by "www.mygame.com" on port 51320. *
- Good mathematical base including types that represent 2d/3d vertexes, matrixes, mathematical functions, geometric objects. Even better if every other library was actually based on that mathematical base, for instance, if every function of the other libraries that requires a xy pair could receive just a 2d vertex instead of 2 integers/floats. I would love it even more if there was no "integer", "float" etc but rather a type "number" with arbitrary precision and support for complex numbers. Methods to integrate, rotate 3d meshes, check for interceptions etc. would be nice.
- Great array support, including the hability to create them without lots of code. Arrays that resize automatically, that aren't bound to specific types, that are smart enough to use the proper internal representation based on what the programmer users. Functions to sort, loop though all elements, find elements based on their variables, for instance
*(array.search(type=Bird,|velocity|>[3]) to search for all elements of array whose type is Bird and modulus of velocity > 3)*.
- Multi-threading support including smart threads that avoid inconsistency by themselves in an easy manner. Even better if the whole language was based in multi-threading. For instance, a "*foreach <x> in <y> do <f>*" that automatically creates a thread running function f for each instance x in array y and returns the threads created; or a "when <expression> do <f>" that will run the function <f> whenever during the execution of the program <expression> comes true.
- Really huge 2d graphics support, including functions to render texts, geometric forms, sprites, apply effects, etc., on a bitmap. Support for plotting graphics of mathematical functions. Support for GUI.
- Good 3d graphics support including functions to load, modify and save 3d meshes in many formats and render them in different projections modes without the programmer having to worry about more advanced topics (but giving the options to do so).
- Huge networking support including the capacity of stabilishing TCP connections, sending UDP messages, make a HTTP request. It would also be cool a feature to simulate a browser including rendering html, css, etc., pages, running javascript.
- Objects to work with databases like Mysql, to work with files.
- You got the point. BUT, NOTE!
1: It doesn't have to be a specific language or library - it can be any combination of languages and libraries if they enable that person of making it's job.
2: It doesn't have to have ALL features on start. If it just has lots of libraries and a fast method for searching and installing them, that counts. But note that, for basic things like a strong array/objects/mathematic base, it is very important that they are built-in in the language or else the libraries won't integrate. For instance, there are libraries for everything in C++, but whenever I need, for instance, to draw a point on screen using allegro [graphics library] I have to write something like point(x1,x2). But the points of my programs are usually represented as 2d vertexes. Now if I have a function that expects a reference to a function that accepts a vector:
*function f(&function(vector) f)*
I would have to write a wrapper for the function point so I can send it to f. It becomes a big problem when I find myself having to write wrappers for every function of an entire library when I need to integrate them to the remaining of my program. Also, for instance. I found the library Wild Magic 5 to compute geometry stuff, and the library Ogre3d to do 3d rendering stuff. Both libraries contains different representations of 3d vectors, though. So if I wish to use a result from Wild Magic on Ogre3d I have to make a conversion. That problem, when many many libraries are used, become a huge problem.
So this is it. Sorry if I wrote too much but I've learned programming and realized all those problems I'm having with the use of libraries. The time I take to make a new program is enourm either because C++ lacks many features, is coustly to write and because finding and installing libraries there is very time consuming (I don't know if I'm doing it right, though). Any light and advises from you more advanced programs is welcome.

For instance, there are libraries for everything in C++, but whenever I need, for instance, to draw a point on screen using allegro [graphics library] I have to write something like point(x1,x2). But the points of my programs are usually represented as 2d vertexes. Now if I have a function that expects a reference to a function that accepts a vector:
*function f(&function(vector) f)*
I would have to write a wrapper for the function point so I can send it to f. It becomes a big problem when I find myself having to write wrappers for every function of an entire library when I need to integrate them to the remaining of my program. Also, for instance. I found the library Wild Magic 5 to compute geometry stuff, and the library Ogre3d to do 3d rendering stuff. Both libraries contains different representations of 3d vectors, though. So if I wish to use a result from Wild Magic on Ogre3d I have to make a conversion. That problem, when many many libraries are used, become a huge problem.
So this is it. Sorry if I wrote too much but I've learned programming and realized all those problems I'm having with the use of libraries. The time I take to make a new program is enourm either because C++ lacks many features, is coustly to write and because finding and installing libraries there is very time consuming (I don't know if I'm doing it right, though). Any light and advises from you more advanced programs is welcome. Thank you. | 4 |

If you had to self-study SICP, which language would you pick and why?
Ideally, I would like to use a language that can run on the JVM.
I can certainly work with a language where REPL works with bash

The code always works when inside the Paypal sandbox (endpoint `https://api-3t.sandbox.paypal.com/nvp`) but never works when connecting to the actual Paypal servers (endpoint `https://api-3t.paypal.com/nvp`).
Libcurl always returns `CURLE_RECV_ERROR`. The general consensus is that this error happens when there is a network problem, so I have investigated that.
I ran the exact same request with the command-line `curl` tool from the exact same server, using the exact same process uid/gid, and it consistently works. Tracking the transfers with `tcpdump` does not reveal any difference in the structure of transactions made by the working command-line `curl` and the non-working application, so it all appears as if the HTTP request is successfully performed in both cases.
Here is the OCaml code that performs the request:
let c = new Curl.handle in
let buffer = Buffer.create 1763 in
c # set_url "https://api-3t.paypal.com/nvp" ;
c # set_post true ;
c # set_postfields "SOMEDATA" ;
c # set_writefunction (fun x -> Buffer.add_string buffer x ; String.length x) ;
c # perform ;
c # cleanup ;
Buffer.contents buffer
Here is the equivalent `curl` command line:
curl -X POST https://api-3t.paypal.com/nvp -d SOMEDATA
What could be the cause of this error? How can I investigate to find out? | debugging | curl | ocaml | paypal-api | null | null | open | CURLE_RECV_ERROR with PayPal API
