App deployment Exception

[Nihal Sequeira]

Hi Guys,
Im getting this error when trying to install my EAR from the admin console in WebSphere app server version 5.0 .This is a well formed EAR and deployment code has been generated in WSAD 5.0 . Do let me know since this is very confusing.
AppDeploymentException: [Application extensions file does not contain a reference to the deployment descriptor. Corrupt ear file. Check if META-INF/ibm-application-ext.xmi uri in the ear file contains a valid application href tag.]
