creating iview using PAR

Dear All,

when I am trying to create iview using the portal component then it is giving there message to me as " no template is present".Can any one tell me why it is? I have created a J2EE application in the NWDS and now want to incude that application as a iview in the portal, if possible tell me the steps to export the J2EE appllication as PAR and include it in the portal.

Best Regards,

Samir
