Define property for JasperReports

[od od]

Hello,

I have problem whith generation PDF reports on Weblogic Server under Windows XP.
I get this Exception : java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource
at weblogic.rmi.internal.ServerRequest.sendReceive .......

I saw on different topic that I have to set the "jasper.reports.compile.class.path" property. But my report are already in jasper format.
Do I have to use JRXML files and compile it (I have a lot of report) or can I set this property and use jasper file directly and that'll work ???
Do I have to define special command to the server ?

This same application causes another NoClassDefFoundError exception on a Weblogic server on linux (at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment). Could you confirm that I have to define the java.awt.headless property to true ?

Thank you.
