Deploying an existing WAR file into the Portal

I have downloaded the Enterprise Portal and the SAP Netweaver Developer Studio (NDS) and have succeeded in creating a couple of projects of the ‘Hello World’ variety and deployed them on the Portal! So far, so good.

The problem I have is that need to deploy on the Portal an existing JSP/Struts application of ours which is available as a Web Archive (WAR) file.

The problem is that I cannot find a way of deploying an existing WAR file on the Portal – either via a Project or otherwise. I have found an entry in the Help files with the NDS which sounds promising, as it is entitled ‘Import a .WAR File into a new project’. However, the menu entry it says you should use (File ‑> Import ‑> MDK: Import a web archive (.WAR) into a new project) this last entry does not exist on my installation of NDS.

Any ideas or suggestions?
