At the risk of boring everyone to tears with this problem, I feel like I have
no option having searched exhaustively (IMO) for a solution both on and off
line. I'm completely at the mercy of those who have been through this before
or those that simply understand iiop much better than I.
I am now in a state where my Java client apparently hangs with no error message
on the client or the server. The last messages on the server side are:

I have been able to invoke the bean using the default method (JRMP according to
one reference) so that gives me a little comfort. I think the simplest thing I
can do is detail what settings I am using and hope that someone sees something
wrong. I'm not against reading documentation, etc. I just haven't been able to
find much wrt iiop.
Here are the settings that my client uses:
<sysproperty key="PROVIDER_URL" value="localhost:3528"/>
| <sysproperty key="EJB_HOME_NAME" value="iiop/TestBean"/>
| <sysproperty key="INITIAL_CONTEXT_FACTORY"
value="org.jboss.iiop.naming.ORBInitialContextFactory"/>
PROVIDER_URL => localhost:3528 (I tried iiop://localhost:3528 but that results
in an exception i.e. unknown host iiop).
EJB_HOME_NAME => iiop/TestBean (this seems to jive with the JBoss server output
listed above)
INITIAL_CONTEXT_FACTORY => org.jboss.iiop.naming.ORBInitialContextFactory (this
is the class that I believe needs to be used, according to the various docs I
have read)
Here's my jboss.xml:
<?xml version="1.0" encoding="UTF-8"?>
| <!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 4.0//EN"
"http://www.jboss.org/j2ee/dtd/jboss_4_2.dtd";>
| <jboss>
| <enterprise-beans>
| <session>
| <ejb-name>TestBean</ejb-name>
| <jndi-name>TestBean</jndi-name>
| <configuration-name>Standard Stateless
SessionBean</configuration-name>
| <invoker-bindings>
| <invoker>
|
<invoker-proxy-binding-name>iiop</invoker-proxy-binding-name>
| </invoker>
| <invoker>
|
<invoker-proxy-binding-name>stateless-rmi-invoker</invoker-proxy-binding-name>
| </invoker>
| </invoker-bindings>
| </session>
| </enterprise-beans>
| </jboss>
When I start my test with those settings above, my client hangs. By that I
mean that the last debug statement I have is displayed right before this
command:
Object foo = ctx.lookup(ejbHomeName);
Nothing else happens beyond this point. Neither java process is consuming CPU
cycles. There are no messages at all on my client or my server. I would have
expected something to be printed out. The only time I've seen something like
this is an infinite loop somewhere but that usually causes massive CPU
utilisation.
As an addendum, when I use these settings shown here, I get success:
<sysproperty key="PROVIDER_URL" value="jnp://localhost:1099"/>
| <sysproperty key="EJB_HOME_NAME" value="TestBean"/>
| <sysproperty key="INITIAL_CONTEXT_FACTORY"
value="org.jnp.interfaces.NamingContextFactory"/>
