Loading classes dynamically form other plugins [message #444814]

Hi,

I've got the following structure:
---------------------------------
- CustomerPlugin (dep. on BasicLibsProject)
- BasicLibsPlugin

Inside BasicLibs I want to load classes from CustomerPlugin dynamically
but it's not working because BasicLibsProject does not find classes
located in plugins it doesn't depends on. Is this somehow possible?

Tom

The problem is that every plugin has its own classloader.
This classloader is especially designed to find classes quickly whithin
the own plugin and plugins it depends on.

So you could try to get the classloader from the CustomerPlugin by
CustomerPlugin.class.getClassLoader() and load the classes with this
class loader. :-)

I think it should work that way.

Regards,
Stefan

The moment you posted you're answer I found the answer myself. Nice to
see other people using RCP in Innsbruck.
