Hello there!

Here is a way, how to integrate ein Standalone Tomcat with JBoss. It's pretty simple. It works with Tomcat4.1.27 and JBoss 3.2.2RC2.

This is answer for these threads:
http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= of all, you need to disable the MBeans of Tomcat (it's possible, that they cause problems). You can do this by commenting following lines in the server.xml like this:

<!--Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"
debug="0"/-->
<!--Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"
debug="0"/-->

2.
After this, copy all JBoss-Client specific libs into the /shared/lib directory of Tomcat. They are located in the /client directory of JBoss.

3.
To call a EJB on JBoss, you need to use the JBoss-specific JNDI properties too. Sometimes, placing the jndi.properties file into the /WEB-INF/classes will do this. You can find this file in the /server/default/conf directory. If Tomcat ignores this, you have to set the properties manually in the source code. Here ist an example:


Properties env = new Properties();
env.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
env.setProperty("java.naming.provider.url", "jnp://localhost:1099/");
env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");

try
{
// Get a naming context
InitialContext jndiContext = new InitialContext(env);
System.out.println("Got context");

// Get a reference to the Bean
Object ref = jndiContext.lookup("MyBeanName");
System.out.println("Got reference");

// Get a reference from this to the Bean's Home interface
MyBeanHome home = (MyBeanHome) PortableRemoteObject.narrow (ref, MyBeanHome.class);

// Create the object from the Home interface
MyBean mybean = home.create();

// call the methods to the Remote Interface
System.out.println(mybean.functioncall());
}
catch(Exception e)
{
System.out.println(e.toString());
}

If you want to externalize the properties anyway, and Tomcat does'nt cooperate, try this hack. With this, you can place the properties files outside the code too:

Properties props = new Properties();
props.load( servlet.getServletContext().getResourceAsStream(
"/WEB-INF/classes/jndi.properties" ) );
InitialContext ctx = new InitialContext( props );
...

Good luck.
