Can't start Portal Express 7 on Windows 2003
===

I have a Windows 2003 SP2 Virtual Box guest in which I'm trying to install Portal Express 7.

During the installation there's a prompt that said that the Server couldn't start and I have to that manually. When I try to start it using startServer.bat I get every time this message:

    ADMU3011E: Server launched but failed initialization. startServer.log,SytemOut.log(or job log in zOS) and other log files under C:\IBM\WebSphere\AppServer/profiles\default\logs\server1 should contain failure information.
    
    ADMU7704E: Failed while trying to start the Windows Service associated with server: WebSphere_Portal;probable error executing WASService.exe: com.ibm.ws.management.tools.ProblemInWASServiceException: ADMU7711E: Unexpected exception associated with WASService.exe: exitCode = -1 during processing of server with name: WebSphere_Portal


In the logs I only found `java.lang.NoClassDefFoundError:com/ibm/ffdc/impl/EmptyProvider$EmptyFfdc` and several `verbosegc.txt` files. Have anyone succeeded in installing IBM WP 7 on Windows 2003?

PS: My problem is very similar to [this DeveloperWorks post][1].
