[Php-java-bridge-users] Setting up Tomcat 6

[<php...@li...>]

Hi -
(Sorry if this gets posted multiple times, but I have had a horrid time 
trying to subscribe/post to this mail list and apparently cannot contact 
the list administrator either, (no replies to my attempts to do so) so I 
have tried to unsubscribe, resubscribe and repost...)

I am following the instructions found at -

http://php-java-bridge.sourceforge.net/doc/tomcat6.php

to integrate PHP with my Tomcat6 server and have ran into a snag which I 
don't quite understand. I got through the first two parts ok -

Download and install Java, Tomcat and PHP
Install a PHP web application into Tomcat

and ran the test examples fine. But when I tried to follow the 
instructions for the third section to make PHP available to all web apps -

PHP support for all existing Tomcat web applications

and tried to execute the small test example I am getting the following 
stack walkback error reported via an HTTP Status 500 web page -

type Exception report
message
description The server encountered an internal error () that prevented 
it from fulfilling this request.
exception

I have placed the jar files in the Tomcat lib directory and they appear 
to be fine with same ownership and permissions as the rest of the jar 
files. Some additional info -

Running under SuSE 11.2  x86_64
Tomcat6 ver 6.0.20-24.6.2  noarch
Java-1_6_0-sun x86_64
PHP5 ver 5.3.2-1.1.1 x86_84

Appreciate any offers of help and thanks in advance..  Marc..

Hi,

> Tomcat6 ver 6.0.20-24.6.2  noarch

Please download and install the original tomcat from apache.org.
Please see http://php-java-bridge.sourceforge.net/doc/installation.php
for details.

Jost - Thanks for your reply, but sorry to report that it resulted in 
exactly the same symptoms. So no joy!
I did a fresh download of Tomcat 6 and placed it in a separate 
directory, stopped my original version, started the new version, 
followed the instructions as previously described and got exactly the 
same servlet exception error...

If both tomcat intances show the same problem, the cause is external,
for example a classpath problem. A "NoClassDefFoundError" for example
caused b a library loaded from an external loader (e.g. the bootstrap
loader).

Please check the cause why your tomcat isn't able to instanciate a
standard Java servlet.

Sravan -  Thanks for your reply, I am not sure what code it is that you would like me to post? Could you be more explicit?

I have not modified the server.xml file in any way, nor does the website instructions tell me to do anything to it. The only file I have modified is conf/web.xml and I included the listener, servlet, and servlet-mappings configurations as described. Would you like me to post it?

     Marc...

Re: [Php-java-bridge-users] Setting up Tomcat 6

[<php...@li...>]

Sorry I did mean web.xml.

There's one thing in particular that I had to fix. In the web.xml file, the
website tells you to type in this line
<init-param><param-name>php_include_java</param-name><param-value>On</param-value></init-param>
The line should in fact be:
<init-param><param-name>php_include_java</param-name><param-value>Off</param-value></init-param>

As well at the head of each PHP file you must include
require_once("java/Java.inc");

The java folder is in each webapp in Tomcat.

If that doesn't help post your php code. I'm using Tomcat 6 and the only
problem I encountered were fixed by the above changes.

Jost -  I fear I am quite baffled by this problem, and don't fully 
understand your reply... My Tomcat6 server is having no problems running 
other servlets, and it is only this php-java-bridge servlet that I am 
having troubles with... I have tried a couple different things to see if 
I could get anywhere and so far no joy...

I installed the 3 jar files - JavaBridge.jar,  php-script.jar,  
php-servlet.jar in the Tomcat6 lib directory - /usr/share/tomcat6/lib on 
my server. I should think the Common class loader would be able to find 
the class file for php.java.servlet.fastcgi.FastCGIServlet in the 
php-servlet.jar file without any problems.  I also tried to install 
these 3 jar files in my local webapp directory where I placed my 
test.php file - ROOT/WEB-INF/lib without success either. So one of the 
class loaders should have been able to find the php-servlet.jar file and 
loaded the FastCGIServlet class ok..

I applied the fixes suggested by Sravan and here is what my test.php 
file now looks like -

<?php require_once("java/Java.inc");
echo java("java.lang.System")->getProperties(); ?>

and I included this lines in the web.xml file  in the conf directory -

<listener>
<listener-class>php.java.servlet.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>PhpJavaServlet</servlet-name>
<servlet-class>php.java.servlet.PhpJavaServlet</servlet-class>
</servlet>

<servlet>
<servlet-name>PhpCGIServlet</servlet-name>
<servlet-class>php.java.servlet.fastcgi.FastCGIServlet</servlet-class>
<init-param>
<param-name>prefer_system_php_exec</param-name>
<param-value>On</param-value>
</init-param>
<init-param>
<param-name>php_include_java</param-name>
<param-value>Off</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>PhpJavaServlet</servlet-name>
<url-pattern>*.phpjavabridge</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>PhpCGIServlet</servlet-name>
<url-pattern>*.php</url-pattern>
</servlet-mapping>

At this point I decided to try a different tactic and removed the 
aforementioned jar files and deployed just the JavaBridge.war file 
instead. That resulted in the following errors -

So another dead end! Ideas?    Marc

Re: [Php-java-bridge-users] Setting up Tomcat 6

[<php...@li...>]

Hi Marc,

I think you've lost it. I admit that the java class loading mechanism
is hard to understand.

But this definitely sounds like a class path problem.


> I should think the Common class loader would be able to find
> the class file for php.java.servlet.fastcgi.FastCGIServlet

If the common class loader loads any classes referring to the servlet
API, I'd expect such errors, yes. Please see our FAQ entry "Why do I
get a NoClassDefFoundError?" at
http://php-java-bridge.sourceforge.net/pjb/FAQ.html


> /usr/share/tomcat6/lib

Remove it. The entire tomcat installation. And remove all "Java" files
from your system.

Download the original tomcat from tomcat.apache.org (any version).
Download Java from Oracle. Install them. Then please follow the
installation instructions from
http://php-java-bridge.sourceforge.net/pjb/tomcat6.php.

Remember to *move* the libraries over to the tomcat lib dir. A *copy*
operation from one class path to the other will cause the problems
you've described. Please see our FAQ "Why do I get a
NoClassDefFoundError?" at
http://php-java-bridge.sourceforge.net/pjb/FAQ.html
