[Php-java-bridge-users] PHP Java Bridge on Apache / Linux Standalone mode

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

We have a Linux / Apache 1.3 / PHP 5.3 web Server running multiple 
websites.
We need to setup a Payment Gateway application that requires JavaBridge
as it is coded in Java.
We do have Java - with JDK 1.6 installed on the server.

We just need to be able to run their Java programs from a PHP script 
that will be called
from a web browser (Actually from WordPress - using the WP e-Commerce 
plugin)
(there is no need to run PHP scripts from the Java app AFAIK) -

So my questions are : 

1) . Can we just use JavaBridge for this purpose - as the documentation 
shows that javabridge can be used as a servlet engine ?
We do NOT want to install a separate Tomcat or other J2EE server.

2) If yes, how do we do this exactly -
 a) Which JavaBridge files do we need on the server  and where do we 
copy these files ?  To the Java /lib folder or to the Website's root 
(public_html) folder ?
 b)  How do we run the JavaBridge app as a service/daemon in  Linux that 
can run in the background ?
( We tried running it from a shell command but it runs in the foreground 
and would terminate once the shell was closed)
c) How do we call the java programs from PHP ?

Although I did go thru the documentation - it is quite confusing as 
there are so many options for the installation.

Any help / advice or pointers to an existing document that describes 
this in detail would be great !

Thanks in advance for any help.
