Hi,

an imported plug-in (not my own) needs access to a class from my own plug-in (to use a static function). I export the package with this class.

What else do I need to do to make my class visible to the imported plug-in?
Thanks for any advice!

This can't work - a plug-in you import can never have a dependency on
yourself because this would result into circle.

BTW: Do you really control the other plug-in, who is in charge of it?

Okay, I understand that this would be kind of a circular dependency. But on the other hand I can get it to work by doing the following:
-copy the jar file (of the imported plugin) to my project directory
-add this jar file to the classpath in the manifest->runtime tab.

edit: but I would like to keep the imported plug-in in maven.
edit2: sorry, what do you mean by "control" the other plugin? I only have got the jar file. The reference to outside classes is done in a text configuration file.

right because then it is part of the same classloader. I'm still not
getting why the external plugin could know a package from your code to
import it, this makes no sense to me.

BTW: Can you please update your forum name - I only see you as "Private
Name" and I prefer to talk to real people.

The external plugin can use static functions which names are given to the plugin by declaring them in a configuration file.

An example (my case): The plugin is an SQL database manager. I would like to call custom SQL invoked Java methods.

I've also tried to export the classes as a plug-in jar and then reimport them, but this seems to not work either.
