We use Genexus(CASE) for programming and the source code is generated and compiled in Java, but the program have been originally compiled for Windows so the thousands (or more) reports use a dynamic library (dll) to show themselves graphically. There's a Linux version of the software, but doesn’t support such DLL, so the reports have to be exported to PDF (There're too many !!). That’s the reason I decided to use Wine to run the Windows version in a Ubuntu OS with the Java virtual machine 1.6u1(Windows version) and it successfully runned, conected and showed the reports without any problems excepting for the fact that when I tried to run it with this command:
