Call Java methods from .jar in EWL [message #826825]

Hi, everybody.

I would like ask you a help once again.

I'm using EWL wizards, and I want to call java code. These two tutorials works 100% fine
eclipse.org/epsilon/doc/articles/call-java-from-epsilon/
epsilonblog.wordpress.com/2007/12/16/using-java-objects-in-eol/

But when I try to use a .jar , I add the required .jar and I'm able to compile successfully.

But in runtime (I started another instance of eclipse) I get a "java.lang.NoClassDefFoundError". I know it's because the .jar cannot be found.

Some months ago, I was able to overcome this problem but now I simply forgot how to solve it. Can you help me?

In advance, I thank you!

First thing that comes to mind is that the jar (I am guessing you added the jar to you project root) is being packaged in your plugin/project. Make sure the jar is checked/selected in the build tab when opening the plugin.xml or correctly added in the build path (if not a plugin project).

Regards,

Horacio
