Can anyone help me to resolve this question?

My rcp application need some external jars, for example, analysis xml jars: dom4j.jar, jaxen-1.1.1.jar. I don't want add them to my rcp application bulid path.
So I make jars to a plugin (new > Project > Plug-in from existing jar archives), then add this plugin to my rcp application, run application has a error:

Warning: Caught exception attempting to use SAX to load a SAX XMLReader

I think the problem is not with the rcp application, it is with the code written for the xml parser. Have you tried writing vanilla application for the xml parser lib that you are using.

But I add jars to my rcp application build path,it's run ok.
I tried another way:
new > project > plugin project, add these jars to plugin project build path, then at plugin.xml "runtime" tab exported packages.
Add plugin project to my rcp application, it's run ok.(before this step, I run plugin project is ok too).
But when I export project, has an error log file:

The import org.dom4j cannot be resolved

This might be due to configuration Manifest file. Please ensure that you have added required plugins in the Require-Bundle attribute.

Require-Bundle: org.dom4j;bundle-version="1.0.0"

I'm sure I did it, it's still has that error.
I create a plugin project, then add this plugin project to my rcp application. it's run ok, but when I export project has an error file:
"The import org.dom4j cannot be resolved"...

But another way:
I create a plugin project, and export this plugin project to a jar, then delete this plugin project from my workspace, and add plugin jar to eclipse plugin directory, restart eclipse, add plugin to my rcp application, it has a compiler error, org.dom4j
can not found.

why?
