Accessing JBoss with Swing client over the internet

[jovial]

hi,

I work on a project that a Swing client should access JBoss server over the Internet. The home interface create() function of a Session EJB bean returns java.lang.NullPointerException when trying to access the server for authentication. The JBoss server is behind a firewall. The firewall has port 1099 opened. Do we need to open any other port?

The application has been tested on the LAN where this error did not appear. I am aware that the latency over the Internet is high and that it could slow down the whole application. Before we conclude that this scenario is not possible I would like to hear if anyone else has been trough a similar situation.

Thanks,

dimitar

I think you should open the RMI port also (4444 ?).

AFAIK, the 1099 port is used to look up the object. This port must be open.
After that, the RMI system opens up the RMI data port and listens on this port for the actual work to do.

Last time I looked (with JBoss 2.4.3), this data port was not fixed but random. The appropriate setting was "RmiPort".

When you're behind a firewall you MUST set this since obviously you don't want to open ALL ports in your firewall.
