Hi,

I have a simple plug-in containing a tree view. I've a package somewhere
else containing a class A. If I try to use the A class in the plug-in view
it simply halt. I've set the java path, everithing compiles whell. If I
debug it, the program halts on the A a = new A(); The constructor is empty.
It seems that it cannot link the class.

The view has a red message after that:

An error has occurred when creating this view

Thank you
George.

Hi,

Seems like more people are having this problem (including me).
I got the error
Unhandled exception caught in event loop.
when I was trying to use a class from an external jar file.

This error is not completely the same as yours, but i guess our problems are
related.
Finally I got it to work. The solution for my problem was very simple:
- add the .jar file to the Runtime libraries on the run-time tab of the
plugin.xml file.
- copy the .jar file to the root directory of the plug-in.
- run as run-time workbench.
- add jar to the libraries tab on the java build path settings.

hope you can use this info,
Mark

ALso, if you are writing a plugin, please look in the help at, PDE
Plugin Developer Environment. It is explicitly for developing plugins.
Modifing the plugin.xml can automatically update your build path for you
with this environment, among other things. It also helps for building
and packaging your plugin.
