Hello,
I'm working on an Eclipse Plugin (the plugin is based on GMF, but not the problem...)
In the first project, "cosa", I've created some classes that uses the Log4J library. When I launch them as a Java Application, everything works right.
In my second project, called "cosa.diagram", I've added a small action that will create one class from the first project. To test my action, I just launch my plugin as an Eclipse Application. I call the action from a custom menu, and boom...
java.lang.NoClassDefFoundError: org/apache/log4j/Logger
I don't now why this is happening... this is code from the action :
public void run(IAction action) {
...
Logger l = Logger.getLogger(this.getClass()); //WORKS !
DeleteComponent.getInstance(); //NoClassDefFoundError
} catch (Throwable e) {
e.printStackTrace();
}
}
