Hi Christoper,

Which exceptions do you get?

I've just tested it on SF, and it worked, at least
HelloWorld.php, HelloWorld2 is difficult to test here.

It accesses a web server[1] which should be able to
run php scripts.

The web server must be on the same machine, though, it
isn't a good idea to allow users to allocate and call
php instances from remote servers. In the current
snapshot you can set   
System.setProperty("php.java.bridge.promiscuous",
"true") to allow this.

[1} i.e. Apache/IIS running php as a module or a
Tomcat or a java AS running PHP as a FastCGI or CGI
binary.

I just got things working on my Mac OS X 10.4.3 box and figured I'd  
post my notes for posterity. I have a pretty common setup and ran  
into a few hiccups so hopefully this will save some others some time!

Version used: php-java-bridge-2.0.8
PHP Version: 5.0.4 installed via fink

Fink Setup
Using libapache2-ssl-mod-php5 / php5-apache2-ssl
Had to install php5-apache2-ssl-dev to get a working phpize command

Build php-java-bridge as directed. Worked very well. Use --with-java= 
$JAVA_HOME to compile against Mac's JVM.

The php-java-bridge script expects the "php" on the PATH to be the  
desired php. You may need to update the PHP path to /sw/bin/php5

PHP Setup
php.ini setup:

extension = /sw/lib/php5/20041030/java.so
[java]
java.log_level="3"
java.log_file="/var/log/php-java-bridge.log"
java.hosts=localhost:9267
#java.socketname="/var/run/.php-java-bridge_socket"

NOTE: the default for php-java-bridge is to use unix sockets  
(java.socketname), but this doesn't work on Mac OS X. Switch to TCP  
by commenting out java.socketname and adding the java.hosts line.

Copy php-java-bridge shell script to /usr/sbin/ and run it.

That's it! After that, the test.php script worked.

Enjoy,
Alan

Hi Christopher,

The examples folder now contains a java-server-faces
example. If you use JSF as your framework, the code
should work "as is". For other frameworks you need to
write a custom ScriptEngine, ScriptContext and
Context, please see the PhpFacesScriptContext,
PhpFacesScriptContextManager, PhpFacesScriptEngine and
PhpFacesContext classes for a template.


> May I attack by bits and pieces using php_closure
> and java_enclosure ?

Yes. Basically you open a URLConnection to the php
instance running in the frontend (Apache/IIS/Servlet
Engine) which triggers the: 
java_context()->call(java_closure()); After that your
java code can call the functions or methods in
allocated PHP closure.


> If so, where may I download the javax.scripts

The script-api.jar is now in the unsupported folder, I
will check in the source, too.  The code was written
and (C) by Sanka Samaranayake (sa...@op...),
licensed under the Apache License.

The source is now in the php-java-bridge/server/javax
folder.  

A snapshot of the current Version 3 source code is
available at:

http://sourceforge.net/project/showfiles.php?group_id=117793&package_id=170256


I will check that code into our CVS as soon as
possible, but currently the SF cvs service seems to be
broken, it rejects everything I commit. In the
meantime please use the source snapshot above.


Regards,
Jost Boekemeier

After having great trouble using java_require, I decided to look at the log very detailly, and I found the following:
 
 Nov 22 08:32:23 JavaBridge INFO : trying to load class: org.apache.nutch.searcher.NutchBean from: [file:/var/www/html/nutch/lib/lucene-1.9-rc1-dev.jar, file:/var/www.html/nutch/nutch-0.7.1.jar]
 
 You will notice that the second path say "/var/www.html/...." not "/var/www/html/...".  I highly suspect that this is not only a bug in the log system, it's a bug in the actual loading class mechanism because when I test it by loading nutch-0.7.1.jar first, it seems that it can find the classes that are in nutch-0.7.1.jar but not the rest of classes that are in other jar file. 
 
 I know that I should put the jar file in /usr/share/java, but it's not the point, and I need to temporary put the jar file in webserver directory for now because I am running webserver on it to test something else.  
 
 Please fix it.

Hi,
   I have been trying to figure this out for couple days, it's driving me mad and I am losing faith on this php-java-bridge.  I have php as frontend and java in backend.  I am calling java functions inside my php file, not the other way around, so no servlet.  I am using 2.0.8.
 
 I have the jar file in /usr/share/java.  I include this file using java_require.  php-java-bridge.log keeps saying classnotfoundexception.  Once I remove the java_require, the exception disappears but there are nullpointerexception and invocationtargetexcept which are probably caused by something else.  So does it mean that I don't need java_require if the jar files are already in /usr/share/java?  According to the documentations, I should java_require the jar files.  
 
 Is there a bug in java_require?  What is the right procedure for including a jar file?  Must I put the jar file in /usr/share/java?  or can I put it somewhere else and then use java_require?  I tried that and it definitately didn't work.  Must I put the jar file in current directory?  
 
 Please list the right instruction of where to put the jar file and when/how to use java_require.  I have already wasted couple days googling around and experimenting!
