I'm gonna help you clean this up a bit and hopefully explain things a bit so that they make sense.

It should point at the base directory of the jdk (similar to what you specified on the --with-java=... expression). In this case, use java.home=/home/local/java/jdk1.2.2 > java.library.path=/home/local/src/php-4.0.4/ext/java:/home/local/java/jdk1.2.2/jre/lib/i386 > This entry is essentially equivalent to LD_LIBRARY_PATH. Not sure if /home/local/src/php-4.0.4/ext/java contains any shared libraries (.so extension). If not, it doesn't belong here. However, you should have /usr/local/lib/php/extensions/no-debug-non-zts-20001214 (location of libphp_java.so) listed here. Also, you might also need to list the other directories in the JDK that may contain shared libraries that you need (e.g. /home/local/java/jdk1.2.2/jre/lib/i386:/home/local/java/jdk1.2.2/jre/lib/i386/classic:/home/local/java/jdk1.2.2/jre/lib/i386/native_threads). A good way to find out what these are is to go into the /home/local/java/jdk1.2.2/jre/lib/i386 directory and run ldd libjava.so and then add the directories that contain the shared libraries that libjava.so depends on to the java.library.path (or LD_LIBRARY_PATH). > > java.library=/home/local/java/jdk1.2.2/jre/lib/i386/classic/libjvm.so:/home/local/java/jdk1.2.2/jre/lib/i386/native_threads/libhpi.so:/home/local/java/jdk1.2.2/jre/lib/i386/classic/libjava.so > Again, you should only have one entry here and it should simply be the name of the jvm shared library (i.e. java.library=libjava.so). This library will be searched for in your LD_LIBRARY_PATH or java.library.path which you specified above. Note that on some systems/jdk's you might need to specify java.library=libjvm.so. Specifically, I found I had to do that on Solaris or I would start getting "Cannot locate CreateJavaVM function" errors. > extension_dir=/usr/local/lib/php/extensions/no-debug-non-zts-20001214 > extension=libphp_java.so > This part looks good. > Any help you can offer is greatly appreciated. > You're welcome.
