fo2pdf problem

Hi all!!

i tried really hard to install fo2pdf on my machine but somehow it simply 
doesnt work. i can successfully create a new java instance in php, but then 
i get the following error

Internal Server Error
The server encountered an internal error or misconfiguration and was unable 
to complete your request...............


__In my apache log there is this entry:
[Sat Nov 20 14:05:44 2004] [error] [client 127.0.0.1] malformed header from 
script. Bad header=[INFO] Using org.apache.xerces: c:/appserv/php/php.exe


Using: Apache/1.3.29 (CGI Versioin), PHP/4.3.4
Java: j2sdk1.4.2_06

The modules required by fo2pdf are in the ext directory of my java.

It would be really great if someone could help me to fix this problem.

Thanks everybody 4 help!!!
greets
Markus
