Our development uses lots of open-source code and I'm trying to figure out what the best way to manage these external dependencies.
Our current configuration:
* we are developing for both linux and windows
* We use svn for our own code
* external dependencies (boost, log4cpp, etc) are not stored in svn. Instead I put... | [

them loose externally makes it very hard to go back to a previous build, or fix bugs in a previous build (especially if the bug is from a change to the external dependency)
Keeping them in svn has saved me lots of headache, and also allows you to get a new workstation able to work on your codebase quickly. | [

In my understanding of Servlet, the Servlet will be instantiated by the Container, its `init()` method will be called once, and the servlet will live like a singleton until the JVM shuts down.
I do not expect my servlet to be serialized, since it will be constructed new when the app server recovers or is starts up nor... | [

4, 5, and 6 are the same thing, only *test* is a pointer. If you want two pointers, you should use:
