JDeveloper 11 G R1 Common Connection Error

In this post I am documenting a common error that one can see while testing the server connection from JDeveloper 11g R1, and its simple solution instead of wasting time in logs etc.

Create a server connection

Verify the connection settings

Now test the connection, in case you see the following error how you would fix?

This happens because JDeveloper uses web proxy to test the server connection. Either add the IP address to the list of IPs so that the JDeveloper by pass, or dont use the proxy at all.

Go to Tools à Preference àWeb Browser and Proxy and add the Server IP, and then restart the JDeveloper.
















Test Again.
