[news.eclipse.tools] Editor plugin: instantiation external class

[pebraert@xxxxxxxxx (Ebraert Peter)]

I am writing an editor plugin for eclipse.
In that editor I try to instantiate a SAXBuilder (for parsing an XML file).
I include the JDOM library that comes with the SAXBuilder in the Build
Path of the plugin.

No compile errors errors occur.

When running the workbench WITH the new plugin, and starting the plugin, I
get the java.lang.NoClassDefFoundError: org/jdom/input/SAXBuilder.

This also occurs when instantiating classes from other imported libraries.

Can somebody tell me what to do?

Thanks,

Peter
