I have installed Openoffice.org3 on our server and it's running in headless mode. We use it with jodconverter to convert word and excell files.

This simple sample code demonstrates the problem. I create an ArrayBlockingQueue, and a thread that waits for data on this queue using take(). After the loop is over, in theory both the queue and the thread can be garbage collected, but in practice I soon get an OutOfMemoryError. What is preventing this to be GC'd, and how can this be fi...

I want to implement a method like this: public Iterator<File> getFiles(String root) { // return an Iterator looping through all files in root and all files in sub-directories of roots (recursively) } In C#, this can easily be implemented with the yield return keyword. In Java, I suspect I have to end up writing a lot of complicated...
I am writing my first portlet based application (for liferay, but the solution should be container agnostic) and I am wondering how people solve to provide links to the user that "lead" to different portlets (maybe on different "pages" in the portal). While you can easily have different view modes inside your portlet, how can you link t...

When writing unit tests for a Java API there may be circumstances where you want to perform more detailed validation of an exception. I.e. more than is offered by the @test annotation offered by JUnit. For example, consider an class that should catch an exception from some other Interface, wrap that exception and throw the wrapped excep...

Despite the fact that both sides are compliant with the standards, WS-Security, WS-Trust, WS-Policy, etc., they don't seem to talk to each other and one or the other will throw cryptic exceptions or ignore security headers. We are using .NET 3....
