JAVA extension install

Hi, I have some problems with installing the java extension for php. My Config : Os : Linux (Mandrake 8.1) PHP 4.1.2 Apache 1.3.23 J2SDK.1.4.0 I had downloaded the source for php 4.1.2 from rpmfind. I compiled the extensions, i had the two necessary files : libphp_java.do and php_java.jar. When i try to access excute a simple script done with the java extension, i have no response, it's take a long time before it's tell me that the page is not found. When i read the apache log , i see that Apache had crached the child. My config in php.ini : java.class.path=/usr/lib/php/extensions/php_java.jar java.home=/usr/java/java java.library=/usr/java/java/jre/lib/i386/libjava.so java.library.path=/usr/lib/php/extensions:/usr/java/java/jre/lib/i386/native _threads:/usr/java/java/jre/lib/i386/client:/usr/java/java/jre/lib/i386/serv er:/usr/java/java/jre/lib/i386 Can anybody help me ?? Thanks
