Locate a java class [message #650946]

Hi,

I currently open reports, that I have designed with Eclipse-BIRT-Report-Designer-Plugin, via WebViewer.display()
out of an RCP-application.

Up to now, I used a XML-File as datasource and everything worked fine.
Now I tried to use a java-class to deliver data.
The java-class is located in the same plugin as the report .

When I preview the result in the reportDesigner-Plugin for Eclipse, it is running, but when I start
the application, it seems that it does not find my java-class.

My dataset-open-script:

importPackage(Packages.com.test.reports.modelprovider);
count=0;
modelProvider = ModelProvider.getInstance();
modelData = modelProvider.getTestdata();

(comment: ModelProvider is singleton with public method "getInstance()")

Now to my question:
When I view the report out of my application, it seems to crash at the script-line:
modelProvider = ModelProvider.getInstance();
What do I have to do, to make the report find this class?

Thanks,
Dominik

PS: I use BIRT 2.6.1 and Eclipse 3.6

Dominik,

Are you setting the parent classloader for the engine?
Take a look at this example:
