[news.eclipse.birt] How to use class java.util.Calendar by scripting?

["Mr. Burns" <Mr._Burns@xxxxxx>]

Hello,

In the initialize trigger of the report I want to use GregorianCalendar 
functions, so I placed following code in this trigger:

importPackage(Packages.java.util.Calendar);
GregorianCalendar GC = new GregorianCalendar(Locale.GERMANY);

but just with these two lines I get following error messages after preview:

Fehler0: Error.ScriptEvaluationError (1 Mal)
Detail: org.eclipse.birt.report.engine.api.EngineException: Bei der 
Evaluierung von Script "importPackage(Packages.java.util.Calendar);
GregorianCalendar GC = new GregorianCalendar(Locale.GERMANY);" sind Fehler 
aufgetreten.

Thanks for any help!
