XPages Java Problem

I added a new source folder (using the java perspective) under WebContent/WEB-INF/src . I can put my packages and classes there and access those through serverside javascript.

But if I change a class’ signature (e.g. by adding a method), all changes aren’t visible from then on (when adding a method, I can’t use it, resulting in a NoSuchMethodError). To me it seems, that it still uses the old classes - even after restarting the http task or the whole domino server. If I rename the class (Right-Click on Class > Refactor > Rename), I can use the added method and changed code.

Even more weird is the fact, that this seems to happen only for some hours. Suddenly it worked again (added a method to a class and it could be called). Then again, this afternoon, it didn’t work again.

A somewhat similar problem using Jar files ist described under feedback number WEBB7RBVNY, but in my situation restarting http or the whole server doesn’t help.

Any help and/or suggestions?

Thanks,

Lars
