PHP + Java = seg fault

I have been trying to get PHP 4.3.1 and java to work nicely together so that I would use xml_fo2pdf. The end result is that it segfaults when trying to use the fo2pdf class. I have simplioed things (per the online docs) and still have the same problem. This is on Linux with a 2.2 kernel and Sun's JDK 1.3_08 and 1.4.1_02 (same results with both). My PHP/Java code which segfaults <? ini_set("java.class.path","/usr/local/lib/php/php_java.jar"); ini_set("java.home","/usr/local/java"); ini_set("java.library","/usr/local/java/jre/lib/i386/libjava.so"); // get instance of Java class java.lang.System in PHP $system = new Java('java.lang.System'); ?> does anyone having this working? Thanks benji
