Hi,

thanks for your answer. but i already tried all your suggestions and
nothing seems to help...
i tried different java versions (sun and blackdown, stable and beta)
i also installed different php versions (4.3.2 and 4.3.3)

i give up now. i think the best idea would be to install tomcat and write
a servlet to generate my pdfs...

greetings
Thomas

Thomas,

Thanks for your message. As your dump indicates, this problem
is related to interoperability of Java VM with PHP and your local
operating system, or is an issue with your particular Java VM. Simply
put, your Java VM crashes in libc and this problem is not related to
XEP.
In order to fix this, I suggest that you try the following:

       1) Examine Java VM version requirements of your PHP
       implementation and use stable Java VM version for your platform
       (1.4.2-b28 is a beta version)
       2) If problem persists, try installing latest stable release of
       PHP environment and test with that using simple java
       applications as well as XEP.
       3) Also pay attention to some serious issues with php_java
       module that are described here: http://tjw.org/php_java/

Sincerely yours,
Nick Filimonov
