Hi,
I'm trying to generate some plugins using a custom code-generator and *without GUI* . When I put my plugin a.b.c_2015.02.16.jar into knime/plugins, I get the following error on startup:
ERROR Worker-1 RepositoryManager Node a.b.c.linux.head.HeadNodeFactory' from plugin 'a.b.c' could not be created: Can't load factory class for node: a.b.c.linux.head.HeadNodeFactory The corresponding plugin bundle could not be activated!
Here is the content of 'a.b.c_2015.02.16.jar'
$ jar tvf a.b.c_2015.02.16.jar

inside a_b_c.jar, there is :

I don't know much things about OSGI. What am I missing ? I tried to compare with a simple Node created with the SDK but I can't see a clear difference at first sight.
What could cause this " Can't load factory class for node: a.b.c.linux.head.HeadNodeFactory The corresponding plugin bundle could not be activated!" ? Can I add some logging/debugging options ?
Thanks !
