I would like to send & receive mesages to JBOSSMQ (jboss 3.2.5) over internet.
The server is behind NAT & Firewall plus DNS. The JNDI lookup keeps on failing.
I traced out the reason being RMI protocol issue. please refer
http://forum.java.sun.com/thread.jspa?threadID=289869&messageID=1242288 Also
tried with HTTP tunneling enabled for JNDI. Below is the stack trace and code
snippet.
