Scripted data source and NoClassDefFoundError

Hi, 
 
I Have a scripted data source and a scripted data set based on the example here <a class='bbc_url' href='http://download.eclipse.org/birt/downloads/examples/scripting/scripteddatasource/scripteddatasource.html'>Created by Camtasia Studio 3</a> 
 
My class is fully implemented and uses other jar dependencies. I placed all my jars files in 
 
- pluginsorg.eclipse.birt.report.viewer_2.3.0.v20080606birtWEB-INFlib 
- pluginsorg.eclipse.birt.report.viewer_2.3.0.v20080606birtscriptlib 
 
and alse added them as jar files resources in my report. 
 
Now when i run my data set with 'preview results' i see my results. 
 
When i run preview report, i get NoClassDefFoundError. It finds my main class but no dependency outside of that class. 
 
Any clue ? 
 
Thanks

Hi seniorcarl,

Are you talking about in the desinger or in the deployed viewer or both, that you're having this problem?

Hi Michael,

I am running in the designer, actually we are using RAD 7.5 with version 2.3.0 of the plugin

seniorcarl,

You should just be able to stick your jar files in the resource folder, which by default is the same location as your report designs. Unless you changed the location of your resource folder, try this and let me know.

Here is the error message

org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report.; nested exception is:java.lang.NoClassDefFoundError...

Is there any specific place i need to put my jar files to be visible for ReportService ?

Ok,

I found the problem, my class was expanded in WEB-INF/classes and it was importing external dependencies in WEB-INF/lib directory. I packaged my class in a jar file, droped it in WEB-INF/lib and then remove content from WEB-INF/classes, restarted eclipse and it worked
