blank page-problem with Lenya2.0.3 and 2.0.2

Hello,

I just see the blank page and no error message in the logfile. How
do I debug to see what is the problem?

- (!) there are no double libraries in the class path
of xerces, xalan, and so on
- the same blank page occurs with lenya2.0.2
- using the built-in Jetty
- Java5 update 22 (because Java6 didn't work) and set "1.5"
  in local.build.properties
- ant in $LENYA_HOME/tools/bin (version 1.7.1)
- the .tar.gz Version for Lenya 2.0.3 and set the
  environment variables
- all files have the same permissions (774)


Cheers!
Daniel
