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
