I have a situation where the deployment platform is Java 5 and the development happens with Eclipse under Java 6 where we have established a procedure of having a new workspace created when beginning work on a given project. One of the required steps is therefore setting the compiler level to Java 5, which is frequently forgotten. We h...

class ClassA { void h() { } } class ClassB extends ClassA{ public static void main(String[] args){ ClassA a = new ClassA(); ClassB b = new ClassB(); } } Yes, everyone think it's such simple and there must and definitely should be only two objects created.

I'm developing various in-house extensions for JIRA, the issue tracker we use. So far I worked with Netbeans and everything worked like a charm. However, now I need to switch to Eclipse and I'm having struggle setting up the environment for this development project. First a clarification why I'm using the approach I'm describing here:...
I get this error when I use my autogenerated ServiceBindingStub.java. WebService side is working ok, so this error must be in code, but code is autogenerated, so I cannot know why it doesn't work.

The documentation of JAXB xjc says: -b Specify one or more external binding files to process. (Each binding file must have it's own "-b" switch.)

I'm having weird problem with java TimeZone.. Calling TimeZone.getDefault() gives my local time zone, which has an ID "GMT+02:00". Funny thing is that this ID doesn't appear in a list provided by TimeZone.getAvailableIDs(). Apparently my zone appears to be "Etc/GMT+2". I'm trying to populate a combo with time zones, but it's impossible...
