How do I integrate with an application that loads a URL that ends with .jsp?

I coul not find the EAR in the PortalServer_root\bp\wp.vwat.servlet\ear\installableApps directory. I found it in the PAA directory, where VWAT PAA was installed. ".../paa/vwat/components/wp.vwat.servlet/intallableApps/ears"
