You're going to want to install the SOA Tooling.
Help-Install New Software :
Choose "JBoss SOA 5.x Development"
Install all available options under "JBoss SOA 5.x Development"
Once installed, you should be able to to do File->New->Other->ESB->ESB Project
Thanks this is what I was looking for. As mentioned above I am trying to work with jbossesb-4.12, could you tell me if my application server which i am using is compatible or not.
