Error while getting remote MBeanServer

When creating a connection from the JDeveloper to the Oracle Application server you might get an error similar to the following.

Error while getting remote MBeanServer for url: ormi://176395.176395-web1.server.domain:12401/default

To fix this add the fully qualified application server name (which is 176395.176395-web1.server.domain in above case) to the hosts file in the client machine that runs JDeveloper which used to access the server.

The hosts file is located in the following locations on the client machine.

Linux - /etc/sysconfig/networking/profiles/default/hosts
Windows - C:\WINDOWS\system32\drivers\etc\hosts

The hosts file should look similar to the following after adding the entry.

127.0.0.1 localhost
83.138.171.4 176395.176395-web1.server.domain

Just adding the entry and saving the hosts file is enough and no need to restart anything for this to work.
