php-java-bridge-users Mailing List for PHP/Java Bridge

Figured out the disconnect and why it wasn't "working" for me...

Turns out that it seems I had the configuration correct at one point,
the browser reporting back the message re: PECL required, along with
your note about PECL "If you want to embed java statements into your php
pages, you must install the PECL extension from sourceforge." turned out
to be the final clue for me and in hindsight was actually working at
that time.

I had assumed, based on the browser output of the phpinfo()-like
information, that the test.php file contained only one line and that
line had phpinfo() on it.  A bad assumption in hindsight.  I opened the
test.php file and saw calls to java includes and then made up a .php
file that had the phpinfo() function as the only line in the file.
Viola, I had 4.4.4, and even 4.4.2 when I pointed the bridge to use my
old version of php.

So the disconnect was that the test.php file didn't run off the bat, yet
php support was enabled.

Next step is to enable support for 4.4.x so that I can call java
servlets and capture return values in my php pages

Couldn't find a PECL extension on sourceforge - do you have a
URL/instructions?  I use PEAR but am not familiar with PECL

Do you use tomcat as the web container? There is an
open bug report connected with log4j. The tomcat
people suggest to copy the log4j library to the global
classpath.

I don't think this is a PHP/Java Bridge issue. It
sounds as if some jboss internal service failed to
start correctly.

Because 90% of all messages posted to this list are
spam. So we cannot allow anonymous posts or posts from
non-members anymore.

I agree that the documentation is currently in a
horrible state. But unfortunately we don't have any
time to update or to rewrite it at the moment.

Not necessarily. Running PHP within a J2EE AS is
faster than the Apache prefork MPM. The only problem
with this setup is that java cannot drop privileges
(due to posix constraints), so you need a native
wrapper which forwards the request from the HTTP or
HTTPS port to the unprivileged 8080 or 8443 ports. In
most cases this "native wrapper" is either Apache with
mod_jk or Apache with PHP and the PHP/Java Bridge.

Certainly. Your setup is described in fig. #3 in the
README.

I can't comment on this one because I have not much
experience with mod_jk. We usually set the Apache
DocumentRoot to the J2EE AS webapps directory and set
up a .htaccess file.

Hi again.

I am replying to my own question post since a friend of mine helped  
me track down my NoClassDefFound problem (thanks Russell).

The error is in the java_require's at the beginning of my code.  I  
needed to use the format java_require(JAR1;JAR2;JAR3;JAR4); instead  
of separating the requires.  There is cross calling in the classes in  
the 4 libraries I use so they must all be brought into the same  
memory space.  See the following reference for full details:

http://php-java-bridge.sourceforge.net/documentation/PHP-API/html/ 
java_8c.html#doc23

I read this before, but it didn't rally gel in my brain until I was  
reminded of how libraries are cached by the back-end loader.

Jon
