I'm looking to generate an XML representation of the AST for a given java class (by parsing its source). Overall, what I want to do is write XSLT queries to find meta patterns in the source code - very much like PMD does. There was an open source utility that started this, but went stale. Anyone know of a utility to do this? -Mike ...
Hi everybody: let me do a bit of "concept mining" here: I am involved in mantaining/extending an application whose functionality is distributed across several servers.

After a lot of research I believe I understand the JMM quite well, certainly well enough to know that when an object is shared between two threads you must synchronize all access on the same monitor. I understand that if multiple active threads access an object concurrently all bets are off as to what they will observe. However, if an ...
it's good practice to write Unittests to be independed of the whole spring application context automate the test you are doing for continuous integration avoid dependency on the Servlet Container I guess with JRebel there's a temptation to test everything in the running application and 'forget' to write Unittests.

Someone designed code that relied on full data; the XML always had every element. The data source is now sending sparse XML; if it would have been empty before, it's missing now. So, it's time to refactor while fixing bugs. There's 100+ lines of code like this: functionDoSomething(foo, bar, getRoot().getChild("1").getChild("A"). ...
Getting lots of additional whitespace in the html output, looks like its because of the JSP tags =/ I saw this referenced somewhere: <init-param> <param-name>trimSpaces</param-name> <param-value>true</param-value> </init-param> That should put it in web.xml, I tried that but that didn't seem to work. Maybe I'm not putting it in t...

Charset issues are confusing and complicated by themselves, but on top of that you have to remember exact names of your charsets. Is it "utf8"? Or "utf-8"? Or maybe "UTF-8"? When searching internet for code samples you will see all of the above. Why not just make them named constants and use Charset.UTF8? ...

The service is exposed through a facade class in the jar file. Hence 3rd parties do not directly bind to the service, they just use the facade class. I have 2 questions about this architectur...
Our swing application uses the "spacebar" key as a shortcut key. In other words, if you press the spacebar anywhere within the application window, it will perform a certain behaviour. What's more, this same behaviour can also be performed by using a JMenuItem in the window's menu bar. The normal way to implement this is to simply ...
