Designer plugin classloader exception [message #1060165]

Hi,
I have developed a scripted data set using JAVA. This dataset is using jax-ws to receive it's data. The dataset is working fine for me and can be used in our own server solution and also in Designer's preview.
Now in additon I have implemented a native RCP Eclipse plugin for uploading the design file to our server. The final jar is just copied to the Designer's plugin directory. This plugin is also using jax-ws and is also running fine.

But now I am running into a problem. When using preview and plugin at the same time without restarting Designer (e.g. running a preview and after that upload design file or the other way round), I'm running into an exception:

java.lang.IllegalArgumentException: interface com.sun.xml.ws.developer.WSBindingProvider is not visible from class loader

The problem seems to be that both implementations are using the same jar-dependencies (which are delivered twice, with dataset and plugin). But as far as I understood every Eclipse plugin should use its own classloader, so where is the problem? Does anyone has an idea whats to do?

Thank you a lot!

Note: I'm using Birt 4.2.2.

Best regards

Mark

Where do you put the jax-ws jar to fulfill the dependency on it by the Data Set?

I have placed the jar dependencies in the same directory as my dataset:
plugins\org.eclipse.birt.report.viewer_4.2.2.v201302041142\birt\scriptlib

Standalone without my additional RCP plugin this works fine.

My RCP-Plugin brings its own jar's with it, all bundled in the plugin.jar.
