Run a proxy process on the host itself that connects to the port, and encrypts the input and output from the socket. | o |
3. | o |
Run a proxy client on the debugging workstation that also encrypts/decrypts the input. | o |
Have this connect to the server proxy. | o |
Communication between them would be encrypted. | p |
4. | o |
Connect your debugger to the proxy client. | o |
As a side note: Our production servers are behind a firewall, but they are exposed to some internal network segments. | o |
Printing Java collections nicely (toString doesn't return pretty output). | p |
I wish to print a CODETERM1 object as nicely as the Eclipse debugger does, i.e., CODETERM2 etc, but printing it with CODETERM3 doesn't return this nice result. | p |
Just to clarify, I'm talking about Java's built-in collection so I can't override its CODETERM4 . | o |
How can I get a nice printable version of the stack? | o |
You could convert it to an array and then print that out with CODETERM1 : CODESNIPPET_JAVA1 . | o |
I like it. | o |
Simple, clean. | p |
To be honest Collections needs a toString method too, but this works also. | p |
@Tovi7 It probably doesn't because most OOTB Collections already provide readable toString()s, whereas arrays don't. | p |
Implement toString() on the class. | o |
I recommend the URL_http://commons.apache.org/proper/commons-lang/javadocs /api-release/org/apache/commons/lang3/builder/ToStringBuilder.html [Apache- Commons-ToStringBuilder] to make this easier. | p |
With it, you just have to write this sort of method: CODESNIPPET_JAVA1 . | o |
In order to get this sort of output:
Person@7f54[name=Stephen,age=29] There is also a URL_http://commons.apache.org/proper/commons-lang/javadocs /api-release/org/apache/commons/lang3/builder/ReflectionToStringBuilder.html [reflective-implementation] . | o |
ToStringBuilder is usually more applicable for beans and objects that carry information, less so for complex data structures. | n |
If the stack object doesn't print all stored items, this won't help. | o |
usage of reflection ToStringBuilder, HashCodeBuilder and EqualsBuilder is highly inefective. | n |
Though the output is ok, these classes are hardly the performance peak of the week... | n |
Also, be careful. | o |
ToStringBuilder uses threadlocal!?! | o |
? | o |
The question explicitly says the class is a built-in collection, so toString() can't be modified. | o |
I agree with the above comments about overriding CODETERM1 on your own classes (and about automating that process as much as possible). | o |
For classes you
define, you could write a CODETERM2 class with an overloaded method for each library class you want to have handled to your own tastes: CODESNIPPET_JAVA1 . | o |
EDIT: Responding to the comment by xukxpvfzflbbld, here's a possible implementation for the cases mentioned previously. | o |
CODESNIPPET_JAVA2 . | o |
This isn't a full-blown implementation, but just a starter. | o |
I know that DP. | o |
But how can I easily print them in a readable format? | o |
The MapUtils class offered by the Apache Commons project offers a MapUtils.debugPrint method which will pretty print your map. | o |
Anything similar in Guava? | o |
Not that I know of. | o |
I'm not terribly familiar with the Guava library but I wouldn't be surprised if there was. | o |
System.out.println(Collection c) already print any type of collection in readable format. | p |
Only if collection contains user defined objects , then you need to implement toString() in user defined class to display content. | o |
Just Modified the previous example to print even collection containing user defined objects. | o |
CODESNIPPET_JAVA1 . | o |
line 21: ToStringBuilder cannot be resolved. | o |
If this is your own collection class rather than a built in one, you need to override its toString method. | o |
Eclipse calls that function for any objects for which it does not have a hard-wired formatting. | o |
And how does eclipse format those classes w/ hard-wired formatting? | o |
That's what I'm looking for. | o |
Be careful when calling Sop on Collection, it can throw CODETERM1 Exception. | n |
Because internally CODETERM2 method of each Collection internally calls CODETERM3 over the Collection. | o |
which java http client library is easy to use for programmatically doing posts, setting cookies and maybe ajax? | o |
which java http client library is easy to use for programmatically doing posts, setting cookies and maybe ajax? | o |
Apache HTTP Component (HttpClient 4.0), URL_http://hc.apache.org/httpcomponents-client-4.0.1/index.html [ URL_http://hc.apache.org/httpcomponents-client-4.0.1/index.html ] Normally, I would just use HttpURLConnection but its cookie handling is too weak to simulate browser behavior. | o |
Looks like the URL has changed. | o |
Try URL_http://hc.apache.org/httpcomponents - client-ga/index.html. | o |
You can use URL_http://www.rexsl.com/rexsl- test/apidocs-0.10/com/rexsl/test/request/JdkRequest.html [CODETERM1] from URL_http://www.rexsl.com/rexsl-test [rexsl-test] (I'm a developer), which does all this work for you, decorating CODETERM2 , firing HTTP requests and parsing responses, for example: CODESNIPPET_JAVA1 . | o |
Async request like AJAX: URL_http://hc.apache.org/httpcomponents-asyncclient- dev/ [ URL_http://hc.apache.org/httpcomponents-asyncclient-dev/ ] Sync request: URL_http://hc.apache.org/httpcomponents-client-4.0.1/index.html [ URL_http://hc.apache.org/httpcomponents-client-4.0.1/index.html ] Cookies is A kind of Header. | o |
Add cookies like A Header: CODESNIPPET_JAVA1 . | o |
Best solution for Java HTTP push (messaging). | p |
We want to push data from a server to clients but can only use HTTP (port 80). | o |
What is the best solution for messaging? | o |
One idea is URL_http://en.wikipedia.org/wiki/Comet%5F%28programming%29 [Comet] . | o |
Are there other ideas or frameworks which offer lets say JMS over HTTP. | o |
(Yes, ActiveMQ supports it too, but waggly IMHO. | o |
And JXTA supports it too but the configuration is complicated. | o |
Something simple is preferred. | p |
) . | o |
The simplest solution for many, many reasons is to use a Comet based approach (like you mention). | p |
This means the clients (to whom you want to "push" messages) open long-lived HTTP connections. | o |
Those connections stay open until they time out or you send the client a message. | o |
As soon as either happens the client opens a new connection. | o |
Directly connecting to clients could be problematic for many reasons: they could be behind firewalls that disallow that, they could be behind proxies and so on. | n |
Unless your clients are real servers (in which case you're really the client), have them contact you and send a response to mimic push. | o |
Is that right? | o |
When the message arrives at the browser a new connection is opened? | o |
The client should be programmed to open a new connection. | o |
If it doesn't the server has no way of communicating with the client. | o |
I'm sorry. | n |
Having trouble understanding. | o |
The client has opened an long-lived HTTP connection. | o |
Server sends messages up there - right? | o |
You then say "Those connections stay open until they time out or you send the client a message. | o |
As soon as either happens the client opens a new connection. | o |
" Sounds like we are opening a second connection. | o |
Why? | o |
The message we just received contained the data we want, doesn't it? | o |
The new connection is to listen for the next message. | o |
The idea here is to keep an open connection to the server at all times that is just waiting for the server to do something with it. | o |
This allows the server to (in effect) initiate communications. | o |
Once the server uses the connection to send a message, a new connection needs to be opened up for the next message. | o |
All of this assumes we have a client that the server needs to be able to push data to. | o |
The alternative is to poll for changes at regular intervals, but that may create a delay in the event reaching a client. | o |
(Apologies for labouring the point, but this simply doesn't correspond to my experience). | o |
The connection is long lived, server squirts up data periodically, browser thread sucks that data and displays it. | n |
I don't see why we need to keep opening more connections. | o |
Right now, I've got real-time measurements updating in my browser, and just one connection (I think). | o |
URL_https://github.com/Atmosphere/atmosphere [Atmosphere] and URL_http://directwebremoting.org/dwr/index.html [DWR] are both open source frameworks that can make Comet easy in Java. | p |
I created an example app using Comet, Raphael, Bayeux, Java and Maven running PaaS Cloudbees and wrote a blog post about it, hopefully it will be helpful to someone. | p |
