error deploying war in WAS 6.1

[Ishita Saha]

Hi,
I'm new to websphere. i'm using RAD 7.0 and WAS 6.1 embeeded in it.
I created a new instance of the server and started the same. Now when through Admin console-> Install new application - i browse my war file (which is running fine in Tomcat 5.0) and give context path and say Next

It says:
The EAR file might be corrupt or incomplete.
AppDeploymentException: [ADMA0084E: The archive C:\Program Files\IBM\SDP70\runtimes\base_v61\profiles\AppSrv01\wstemp\0\upload\fwtservices.war to wrap is not a module of type JAR or WAR.]

I searched on this forum - there are other posts on this topic but i couldn't find a solution.

My application is also using two external jar which i've added through build path.

Please advise the solution.
Thanks

The application file specified is not a valid jar or war. ensure that your war is fit to deploy in WASD.it requires dependecy files pertaining to WAS, so that the deployer can understand that its a jar etc..
