Roughly, how does standalone tomcat communicate with JBoss?

[erikrod]

Hi!

I'm doing a project where we have to install an application to do measurements on it. The design requires a standalone tomcat 5 to run on one computer and the application-server on another.

I've got them both working seperatly.

The thing is that I'm quite new to both JBoss and Tomcat and I'm a bit unsure of how Tomcat finds JBoss and how they communicate.

I've spent a few hours reading the forums and I'm a bit wiser than i was, but there's still quite a bit I don't fully understand.

I don't need a detailed description of what to do, but a rough outline of which steps need to be taken to make them communicate would be much appreciated.

Some more specific questions:
The tomcat uses something called jk1.2.x connectors to communicate with the jboss-server when it's standalone?
The tomcat accesses the EJBs by looking the up in the application servers JNDI. How does tomcat know which JNDI to look in (where are ip-adresses/port numbers specified?)?

Any links comments or explanations that can get me started would help me very much (then I'll go bck to reading forums and googling to find out just how it's done).

It seems to me your servlets/jsps in tomcat can lookup ejbs as if they're are stand alone java clients, i.e. via jndi. Just make sure you configure your jndi.properties file correctly and make it accessible in your web application's classpath.

Cheers.

If I've understood this right:

The JNDI is a service that Jboss runs.
The jndi.properties file is a part of jboss (not standalone tomcat).

How does the servlets/jsps (running on another computer) know where to find this JNDI?
Do you mean that it should be hard-coded in my servlets/jsps? I would imagine that tomcat had some kind of configuration file refering to a specific jndi-service.
