EJB Deployment problem

[Vikram Chhibber <vi...@pspl.co.in>]

Hello,
    I have a problem deploying EJBs (.ear) files created by ANT on J2EE reference implementation server. I am creating the manifest file using ANT ear task but the server gives the following error:

java.io.IOException: Incorrect Manifest format

I am using deploytool.exe from command line.
