Why does your Java work with you PHP?

Anon

I try too to find some documentation about Java Native support for PHP, because I was not able to install the extension properly to work.

I'm using Apache 1.3 and PHP 4.02 on WinNT and it works really fine. Now I download the java extension from php.net and extract all the stuff in my PHP repertory (c:\php4).

I made the change in the php.ini [java]
extension=php-java.dll

java.class.path=="c:\php4\php_java.jar;c:\jdk1.2.2\lib\;"

java.home=c:\jdk1.2.2\bin
java.library.path=c:\php4
java.library=c:\jdk1.2.2\jre\bin\classic\jvm.dll

The only thing I can't do is to use the msdev... because I don't have msdev and I have no idea what is it and how it shoud be work and where you have to use it.....

SET JAVA_HOME=D:\jdk1.1.8
msdev ext\java\java.dsp /MAKE "java - Win32 Debug_TS"

And it doen't work. The examples doesn't work and i can't find more information.
The only thing I found, was in forum like this and everybody is saying it works. But not with me!!!!!!

Please, help!!!!!!

Well if you already have the dll then you don't need the msdev part because all that is for is for compiling custom builds of the java mod. What you do apparently need however is a copy of the java JDK installed on your server. I'd love to tell ya that I got this to work myself but I spent 3 days working on it and I gave up for now, unfortunatly I have to go back to this eventualy because I require it to use a Java component for an e-commerce site I'm building for a client. Anyways I tell you about the JDK thing because this is as far as I got and I figure it might help you to at least get up to where I left off.

If anyone else knows how to actualy complete setting this thing up I'd love to hear it, it'd save me one major headache in the future.

I wonder, does the server software also have to support java applets for this to work properly?

Hi,

Thanks your for your answer. I had already installed JDK 1.2.2 on my machine and install the java/extension for this version of JDK. But it really doesn't work.

Now, I'll try to use PHP and Java with Linux. I heard it would be possible to link PHP with Tomcat and Apache and that it would be work. Perhaps this will give you new idea.

Thanks,
Olivier

Actualy I just solved this problem yesterday, it's all just a matter of putting the right values into the php.ini file, something that there is no documentation for. I actualy found the answer while cruzing the old forum posts. I'm on another computer for tonight thou and I can't remember the strings off hand so I'll toss it up tomorow when I get back to my own comp.

So it does work, it's just a bit weird to implement...

This solution works with all the examples except jawt.php, this is probably because of some of the functions used in it, it says at the top of that script that it is only for use with the cgi version and I use the apache module...

Anways so download JDK 1.3 from Sun.com and toss these lines in you php.ini file, if you're using the module version you'll need to restart the server after you modify the file.

~php.ini~

[java]
java.class.path="c:\web\php4\extensions\php_java.jar;C:\jdk1.3\jre\lib;C:\jdk1.3\jre\bin\"
java.home="C:\jdk1.3\bin;C:\jdk1.3\jre\bin\"
java.library.path="c:\web\php4\extensions\;C:\jdk1.3\jre\bin\"
java.library=C:\jdk1.3\jre\bin\classic\jvm.dll
extension=php_java.dll

Hope this helps you as well as it did me, if you're install directory for jdk1.3 is diferent than mine then you will need to modify the above changes. 🙂

Hello Shaun,

Really thank you, it's work. You were right, it's only a question of configuration.

Now I will test it, but it's seem to work fine.

Thanks!!!!

Dear Sir:
Although I follow the configuration of Shaun Hawkes, the server give me the message "Fatal error: Unable to create Java Virtual Machine in E:\Inetpub\NetAdm\jver.php on line 4
"

How do I solve it?

Anon

Dear Valentin,

The first to do, I suppose, is to test if your JDK works. Try to open some examples from the ...\jdk(...)\demo\applets, to see if it's work. If it doesn't work, then something is wrong in your install. Try to install JDK1.2.2 from SUN or JDK1.3 from IBM. The two version work fine....

If it's work, the something could be wrong in the configuration file of PHP or the java-extension class for PHP is not in the right repertory. Check that you have the right things on the right place.

I choose to put the "php_java.jar" and "php_java.dll" in my PHP repertory (also c:\php4).

Then I install jdk1.2.2 from SUN in c:\jdk1.2.2

The I put my php.ini in c:\winnt and wrote inside:

........

;;;;;;;;;;;;;;;;;;;
; Module Settings ;
;;;;;;;;;;;;;;;;;;;

[java]

java.class.path="c:\php4\php_java.jar;c:\jdk1.2.2\jre\lib;c:\jdk1.2.2\jre\bin\"

java.home="c:\jdk1.2.2\bin;c:\jdk1.2.2\jre\bin\"
java.library.path="c:\php4\;c:\jdk1.2.2\jre\bin\"
java.library=c:\jdk1.2.2\jre\bin\classic\jvm.dll
extension=php_java.dll

[Syslog].......

And at last, I DELETE the php.ini in my c:\php4 repertory. It was the stupid error I have gone along several days, that I don't understand why I saw no change in the way my PHP work, when I change the c:\winnt\php.ini

I hope it could help you.

By the way, the "jawt.php" really don't work on the windows machine. Perhaps because you have to use it as a cgi. But it work fine on Linux and it is now the direction I decide to follow, to study the behavior of PHP with Java.

Bonne chance!!!!!

Good to hear...

I only got it to work with the test scripts, I still havn't had time to properly test it out with others, I'm just entering that phase of the project right now, knock on wood.

Anon

Have you been able to run any of your own classes?

I can get all of the examples to work, but get classNotFoundExceptions when i try to run my own classes. Where should my own class file be kept, which line configures this?

Anon

Hi,

You have to be sure, that your classes are read by JVM. With WinNT, I put my classes in the
c:\jdk1.2.2\jre\lib\myClass.jar or .class or what you need

than in PHP, I wrote

$myClasseObject = new Java("whole path to my class");

Have fun!
