BIRT reportEngine.openReportDesign(stream) hangs

[wernerreiche]

I am using BIRT to generate PDF reports.
The code I have works in the development environment (windows), but when I install it on the operational system (centos), the OpenReportDesign call hangs. It just never returns from the call. Any ideas?

The output from the using version message is:

IReportRunnable report = reportEngine.openReportDesign(stream);

The complete method is:

return baos.toByteArray();
}
