Hello,
I have small problem and I am not sure how can I solve it. I have created
Interpreter Plug-in which uses Velocity Code Generator Engine. When I lunch
my application and than invoke Interpreter eclipse can not find required
libraries(velocities'). I do not know how I can add to gems external
libraries. I have tried different configuration(import external jar
archives, link compiled classes etc.), but nothing is working. Please see
error which I am getting bellow.

Hi Krzysztof,
Glad you fixed the problem.
It doesn't sound like you need to do this, but just in case you ever do:
Eclipse can get tricky if you need to use Class.forName() to instantiate new
objects from different plug-ins. If you ever run into a situation where you
need to do this, the best way to do it is:
Classloader orig = Thread.currentThread().getContextClassloader();
try{
Classloader c = //..get a reference to the classloader of a class
//from the plug-in you want to dynamically load
classes from
Thread.currentThread().setContextClassloader(c);
Class c = Class.forName("foo");
...
}
finally {
Thread.currentThread().setContextClassloader(orig);
}
Thanks,
Jules
