My (bar-chart)report is supposed to display the time spent on certain projects (with the project title on the x-axis and the spent hours on the y-axis). I have to convert my xml datasource to a scripted datasource and have the following problem:
When I click the preview tab below the work-area I get the following error message:
Error.ScriptEvaluationError ( 1 time(s) )

This is the relevant code from my open-method of the dataset:
p = new Packages.klassen.ProjectEfforts();
projArray = p.getProjectEfforts();
numberOfProjects=projArray.length;
currentIteration=0;
Deploying to JBoss creates the same error.
Strangely, when I click "Preview Results" in the edit dataset window, the results are displayed correctly.
My java classes are located in a Maven Project and my BIRT-Reports are located in a Web-Project. I've put any relevant jar-files into probably any possbile directory. Into the birt/scriptlib directory of eclipse/plugins/org.eclipse.birt.report.viewer_2.3.2.r232_20090212, into the according WEB-INF/lib directory, into the scriptlib and lib directories of my Web-Project and of the BIRT Report Engine itself.
Setting up a project reference in Eclipse didn't work either. I'm absolutely clueless.
By the way: The error message thrown when I double click my chart is a little different:
TypeError: [JavaPackage klassen.ProjectEfforts] is not a function, it is org.mozilla.javascript.NativeJavaPackage.
