Re: [PHP] PHP and Java (CVS version)
Evan, It sounds like your PATH doesn't contain the JDK/bin directory. What happens if you type "which jar" at a command shell?

Re: [PHP] can i install apache php-module AND php-cgi on the same windows-apache?
Sebastian, I see no reason why you couldn't. I believe at one time I had CGI, Apache and Servlet all serving up PHP using different extensions in Apache on Win32. However, it's been a while so don't hold me to it.

Re: [PHP] Java Servlet Support
Shawn, The PHP distribution contains various SAPIs (server API's). Examples are CGI, Apache, ISAPI, NSAPI and Servlet. Each of these SAPIs is optimized to host the PHP interpreter in the respective environment. Thus, if you want to run PHP in Apache, you can use the Apache SAPI (also known as mod_php) instead of CGI which will give you much better performance as well as being able to take advantage of the capabilities of that API. The sapi/servlet option is essentially a Java servlet that you add to your Java webserver just like you would any other servlet and it invokes the PHP engine through JNI and reflection (so you could reference Java objects from within your PHP script). This option is much more efficient then just running the ext/java extension (which allows you to access Java objects from PHP by starting up a JVM per session) since the JVM used is already running in the Java webserver and can be managed much better by the latter than anything ext/java can attempt to do. Note that using this SAPI implies that PHP will be running in your Java Webserver instead of on your HTTP webserver (e.g. Apache) which could have implications (hopefully for the better) unless they're both running on the same physical machine. Let me know if you have other questions.

Alex, Ok...so far, I have progress. I have PHP recognizing Java... or at

It's really confused since you gave it way too much information. I'm gonna help you
clean this up a bit and hopefully explain things a bit so that they make sense. See
below.
Here is the appropriate info from my php.ini file:
[Java]
java.class.path=/home/local/src/php-4.0.4/ext/java/php_java.jar:/home/local/java/jdk1.2.2/jre/lib:/home/local/java/jdk1.2.2/jre/bin
Remove the last two directories as they serve no purpose. This entry is essentially
an extension to the system CLASSPATH and should only contain directories and jars that
contain java classes
or java resource files.
java.home=/home/local/java/jdk1.2.2/bin:/home/local/java/jdk1.2.2/jre/bin
There should be only one java.home. 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. Hope this helps.

Try replacing the green_threads specification with native_threads (if your JDK has this subdirectory). If I recall correctly, libhpi.so is in native_threads. Again, I'd suggest setting LD_LIBRARY_PATH temporarily to what you have up in java.library.path (after replacing green_threads with native_threads) and then run ldd libjava.so from the command line to see if everything is found. BTW, if your JDK doesn't have a native_threads subdirectory then you might need to use a different JDK for PHP/Java to work correctly. Did you ever mention what JDK you were using? java.library=/home/local/java/jdk1.2.2/jre/lib/i386/libjava.so Simply use java.library=libjava.so (let it do the search).

This is driving me nuts. Relax and believe! We're almost there but you mustn't lose faith. Let's leave PHP out of things and just figure out your JDK.

Re: [PHP] ext/java causes segfault in Apache
Brice, I just checked in some fixes to the ext/java/config.m4. Are your changes similar or would you like to share if they're not? As far as not being able to start JVMs, I suppose it could be a memory management issue (each JVM is somewhat resource intensive) so it's rather inefficient to do Java from PHP in this manner. I thought you're only supposed to get one JVM started per session so I'm a bit surprised it's trying to start a new one each time. A much better way to run Java in PHP is by using the PHP/Servlet feature which gives you the same capabilities but without the JVM management headaches (although there may be other headaches/bugs in PHP/Servlet that may cause failures after a few attempts as well, which I'm currently investigating). The caveat is that you'll need a Servlet capable web server such as Tomcat or JServ plugged into your Apache.

Re: [PHP] PHP ext/java and sapi/servlet reliability
Juan, I'm currently looking at the Java/Servlet code and trying to get it to be a little more stable (Sam appointed me to this task a few months ago and I've been slowly coming up to speed). I apologize on Sam's behalf for not responding to you but he's moved on to other responsibilities which involves a lot of travel and he may not be as attentive to the needs of PHP users as he may have been in the past. So far, I found that the Java feature is very inefficient since it starts up a JVM per session and could quickly max out your machine's resources. The Servlet feature, on the other hand, is much more practical but there may be some reentrancy bugs in it as I always get a trap after 3 attempts if I compile without debug. However, enabling debug appears to mask the problem so that it doesn't trap (at least with my limited testing). I hope to have this fixed soon and we're planning to take it through some more intensive stress testing to make sure it's ready for prime time. Watch this space.
