Hi Scott,
The javax.naming.CommunicationException is the archtypical message but it can be
caused by various sources. Here's what I've tried
- not all of this *may* be necessary anymore, but I haven't seen an answer on this
question yet.
What I have here works on Beta Prod 1. But it's "folklore" as far as what is actually
required by FINAL.
1. On JBOSS, Ensure that both your RMI and JNDI hosts are set up (i.e. not set to
localhost). Earlier versions defaulted to
localhost. In the JBOSS FINAL version, the defaults are commented out. So you could
probably set the the hosts using -D.
Otherwise, just uncomment the lines and fill them out in:
jboss.properties:
java.rmi.server.hostname=myserver.xxxx.com
jndi.properties
java.naming.provider.url=myserver.xxxx.com
2. In the client, do a complete upcast for the lookup:
MyBeanHome ref = (MyBeanHome) ctx.lookup("MyBeanName");
Instead of
Object ref = ctx.lookup("MyBeanName");
The "connection refused to 127.0.0.1" message seems to come from not upcasting.
Also if you look in Zol:
zola/src/java/org/jboss/zol/testbean/client/EjbossClient.java (dated 9/25/00)
It does:
StatelessSessionHome statelessSessionHome =
(StatelessSessionHome) ctx.lookup("nextgen.StatelessSession");
There are some other clients in Zol - some of them are coded "Object ref =", but
most appear to be earlier than 9/25/00.
Let me know how it goes.
Regards,
Rich Katz
