Adapter module deployment problem using Visual Admin

Hi,

I developed an adapter module and trying to deploy it on the J2EE engine.

I went to VIsual Admin -> Services - > Deploy -> I chose Application then clicked on Deploy. I selected my EAR file and it was giving "cant covert EAR file" error.

Could you please help me? We have some issues with SDM so I wanna deply with VA.

Thanks in Advance
