Solving http tunneling is disabled weblogic

####<2010/10/28 11:05:07 AM> < [ACTIVE] ExecuteThread: ‘0’ for queue: ‘weblogic.kernel.Default (self-tuning)’> <> <> <> <1288256707334> Login rejected with code: ‘Failed’, reason: java.net.ProtocolException: HTTP tunneling is disabled

Usually this error comes:
If you’re accessing the WebLogic admin console via a SSH tunnel, or via a network interface that the admin server is not listening on, weblogic will throw this exception. It may so happen the WAS Admin was hung or not responding.

Avoiding the error:
In the left-hand navigation, click on the domain then ‘Servers’. In the list of servers that is displayed, click on the server throwing the error. Click on the Protocols tab, then HTTP sub-tab. Ensure ‘Enable Tunneling’ is checked. Activate your changes and restart the managed server.
