Issue with accessing UCM port 4444

[ksniranjan]

I've installed virtual box on a linux machine. Following appliance is running on the Virtual Box.
http://www.oracle.com/technetwork/middl ... 84132.html
It is a webcenter UCM installation.

Port forwarding seems to be working perfectly. Because I can access all the required ports from the host machine and also from external machines.

However, I'm unable to access port 4444 from outside the host machine. When I try to create a Content Repository connection on my windows Jdeveloper, it throws below error:
Caused by: oracle.stellent.ridc.protocol.ProtocolException: Unable to initialize socket connection to Content Server 'idc://<host>:4444'
at oracle.stellent.ridc.protocol.intradoc.socket.SocketConnectionManager.initializeConnection(SocketConnectionManager.java:32)
at oracle.stellent.ridc.protocol.intradoc.socket.SocketConnectionManager.initializeConnection(SocketConnectionManager.java:19)
at oracle.stellent.ridc.protocol.impl.SimpleConnectionPool.acquireConnection(SimpleConnectionPool.java:44)
at oracle.stellent.ridc.IdcClient.sendRequest(IdcClient.java:148)

Any clue?
Is the IDC protocol a problem?
or Is it the UCM server that is restricting access from any machine other than the host?

1) Goto Oracel VM Menu Device --> Network --> Networks Settings
2) From LHS , select Network. Click Port Forwarding .
3) Click Add Button (+) and add the UCM Port 4444.
4) Click OK and try connecting using Jdeveloper.

Thank you.

I'm afraid that "ksniranjan" had only one post and they last visited the forums on 16/11/2011, so, chances are they won't see the answer. But bonus points for offering a solution .
