PHP + JAVA ext

Anon

does anyone use PHP Java extension under FreeBSD successfully?

Why I always get the message:

Fatal error: Unable to load Java Library /usr/local/jre1.1.8/lib/i386/green_threads/libjava.so, error: /usr/local/jre1.1.8/lib/i386/green_threads/libjava.so: Undefined symbol "fmod" in /usr/local/share/doc/apache/test.php on line 2

in test.php, only one line: "$system = new Java("java.lang.System");"

Thanks for your help!

Hi,

I don't use FreeBSD but I compile PHP with Java under Linux and it works (almost). I used JDK 1.2.2 from SUN. I think it may be a difference. JDK 1.3 from IBM gave me good results also.

Perhaps it will help you.

Olivier,

What do you mean by "it works (almost)"?

Also, please explain what you had to do to get IBM JDK 1.3 to give you good results. I've not been able to get it to work (I get the same error of not
being able to load the libjava.so) in Apache (although the script works from the
command line). The Blackdown JDK 1.2.2 worked well for me.

BTW, I'm currently at ApacheCon Europe. If you're here also by any chance
I'd like to get in touch with you if possible. You can leave me a message on
the conference message board about where to meet you and I'll check it
regularly. I know it's a long shot but it's worth a shot 🙂.

Hello Alex,

I don't how much you already know know about compile PHP. Then i try to explain as more as possible what i have done.

I compiled PHP 4.0.3pl1 with both JDK1.2.2 and IBM JDK 1.3 under Suse 7.0. I use Apache 1.3.12 as WebServer.

Both compiled PHP worked well and I get it the same way. The following is how I do it:

A- Compile your PHP:

A-1- untar xvf php-4.0.3pl1 in the directory you want. I choose (/home/obaillard/devl/devltools/php-4.0.3pl1/), but it's up to you to choose what you want.

A-2- compile PHP:
In your new PHP directory (/home/obaillard/devl/devltools/php-4.0.3pl1/), do:
./configure --prefix=/home/obaillard/tmp/ --with-apxs --with-mysql --with-java=/home/obaillard/dev/devltools/jdk1.2.2/ --enable-ftp --enable-debug
for example if you want to use JDK 1.2.2. The --with-java option point only to a local version in my home directory. But it doesn't matter where you JDK is.

A-3- make PHP:
do: make install

At this point, I become the error, that I can't copy a file in the /usr/local/local. I suppose it's because I compile PHP as normal user and not as root. I don't understand it really because i choose the option "--prefix" so that it point in my home directory. Anyway, it doesn't seem to disturb PHP.

A-4- All right. PHP ready!

B- Update Apache httpd.conf
B-1- Personally, i toke the libphp4.so from the /home/obaillard/devl/devltools/php-4.0.3pl1/libs/ directory and made a copy in the (/home/obaillard/devl/devltools/modules/ directory. It's the location where I put all my modules for apache.

B-2- Change httpd.conf
The config file have to contains the following commans:
<IfDefine PHP4>
LoadModule php4_module /home/obaillard/devl/modules/libphp4.so
</IfDefine>
......
<IfDefine PHP4>
AddModule mod_php4.c
</IfDefine>
......
<IfDefine PHP4>
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
</IfDefine>

B-3 Reload or restart your Apache
I use a local httpd.conf. Then I use the following command:
/usr/sbin/httpd -f /home/obaillard/...(path to my httpd.conf file)/httpd.conf -DPHP4

If you don't use a local version of httpd.conf but the main version of apache, then you have to look in the /sbin/init.d/apache script if you find the command
test -e /(path to your libphp4.so)/libphp4.so && MODULES="-D PHP4 $MODULES"
If not, write it.
Then restart your apache:
rcapache restart

Hopfully will it works!!!!

About -- What do you mean by "it works (almost)"? --. I say almost because I want to use PHP as servlet with apache and tomcat. Apache is responsible of normal HTML page and .php extension are redirect to Tomcat who 'll use PHP servlet to handle the request. This means I compiles PHP with the --with-servlet option and the --with-java option. With this options, I can't connect normally to a MySQL database with "mysql_connect" -- When I try. I only wait and wait and nothing happens --. But I can connect to the MySQL with a java class of mine who is using JDBC. Oracle and others stuff work fine too.
The other problem I have with java extension is that I can only exchange simple type variables between PHP and JAVA world. Also I mean int, boolena, string and table of this simple type. I have found no way to exchange some more complex data structure.
And finally only with IBM JDK1.3: When my TOMCAT run using this version of java, then it simply "freeze" after some time (15 minutes until some hours ?!?!?) and nothing more work. With JDK1.2.2, it doesn't happens.

So I hope it will help you. If you have more interessing experiences with PHP/JAVA I would be naturally happy to hear of it. I think it's really not to bad.

Bye,
Olivier

I want to build PHP support with java in linux.
but everytime I failed.
my enviroment is:
php4.0.6,linux7.1,apache1.3.22.
I build it with java option value to my JDK directory.
and when I visit it on web,it take a very long time to wait,then found the page can not show error.

can you help me to fix it,or do you have some instruction about it?

Anon

Hello David,

It's a long time I do something with PHP + Java, but I think it is a grat things.

At first, did you already read the following thread?

http://www.phpbuilder.com/forum/read.php3?num=3&id=101944&thread=101920

Then, you have to do some settings in your php.ini:

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

[java]

java.home="/home/obaillard/devl/devltools/jdk1.2.2" --> where to find your java installation.

java.class.path="/home/obaillard/devl/modules/php_java.jar:/home/obaillard/devl/devltools/jdk1.2.2/jre/lib/rt.jar:/home/obaillard/devl/devltools/jdk1.2.2/lib/tools.jar:/home/obaillard/devl/devltools/php/classes/portal.jar:/home/obaillard/devl/devltools/php/classes/olivier.jar:/home/obaillard/devl/devltools/php/classes/mysql.jar:/home/obaillard/devl/devltools/php/classes/aurora_client.jar:/home/obaillard/devl/devltools/php/classes/mts.jar:/home/obaillard/devl/devltools/php/classes/vbjorb.jar:/home/obaillard/devl/devltools/php/classes/vbjapp.jar:/home/obaillard/devl/devltools/php/classes/classes12.zip:/home/obaillard/devl/devltools/php/classes/client.jar:/home/obaillard/devl/devltools/php/classes/bean.jar" --> where you put ALL paths to the libraries you need to run your programms AND java itself

java.library.path="/home/obaillard/devl/modules:/home/obaillard/devl/devltools/jdk1.2.2/jre/lib/i386:/home/obaillard/devl/devltools/jdk1.2.2/jre/lib/i386/classic:/home/obaillard/devl/devltools/jdk1.2.2/jre/lib/i386/native_threads" --> paths to java classes.

java.library="/home/obaillard/devl/devltools/jdk1.2.2/jre/lib/i386/libjava.so" --> path to the run-time library of java

extension_dir="/home/obaillard/devl/modules"
extension="libphp_java.so" --> --> path to the php-java extension library. You get it after you compile PHP with the options given in the thread I give you.

This should work for JDK 1.2.2 from SUN. Try it with this JDK then when it works, try it with other JDK. If you feel good, you can directly try with other JDK.

Good luck!

5, set [Java] section in php.ini

java.home = /usr/local/jdk1.2.2
java.class.path = /root/me/apache_1.3.22/htdocs/ss.jar:/root/me/php-4.0.6/ext/java/php_java.jar:/usr/local/jdk1.2.2/jre/lib/rt.jar:/usr/local/jdk1.2.2/lib/tools.jar

<?
$formatter = new Java('java.text.SimpleDateFormat', "EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz");

print $formatter->format(new Java('java.util.Date'));
?>

testjava.php source code

<?
$ss=new Java("ss");
echo $ss->getInfo();
?>

public class ss {

public ss()
{
}

public String getInfo()
{
String sRet;
sRet="davidliu";
return sRet;
}
}

then
1,I run
jar cvf ss.jar ss.class
***so ss.jar locate in /root/me/apache_1.3.22/htdocs

2,I start apache server and I know PHP and Oracle is OK.

the browser is waiting and waiting for a long time until the page can not be show error found.

I don't know why?
Please help me,thank you very much.

Best Regards,
David

Hi David,

I try your code on my Linux/PHP. It works.

Momentary I have no idea why it doesn't work by you.
Your LD_LIBRARY_PATH is ok

The [java] settings for PHP too.

Anyway, I am using PHP 4.0.3. An collegue say me, PHP 4.0.6 is something special. Another possibility is that your have compiled PHP with Oracle. I had already difficulty with PHP, Oracle and Java together. I think is because Oracle is working with is OWN JDK (version 1.1.8!!!!) and there is a conflict with the JDK 1.2.2.
Try perhaps to make another lihphp4.so with JAVA and without Oracle.

I can't say why it doesn't work by you because I have no error message. If your browser is hanging on, then you should have an error message in the log file or in any other log file.
Could you send me the error message you get then?

PS: Today is my last day here, then I am ín holiday next week. So if you whant an answer: be quickly!!! -🙂

Bye!

Olivier
