I'm working on Eclipse plugin development. At one place, I need to load classes from external jar and read its methods annotations. Unfortunately, when I call method.isAnnotationPresent(MyAnnotaion.class), it return false all the time (I run/debug the plugin from Eclipse). If I run the snippet from JUnit (from Eclipse), it works fine.
Any suggestions?

I'm sorry for disturbing. The problem is solved. My problem was that MyAnnotation was in jar outside eclipse and I had to add Eclipse's classloader into myJars classloader...

Artem,

What do you mean exactly by "load classes from external jar"? Is that
jar a library specified in the MANIFEST.MF of a bundle?
