Regd SDM in SAP WAS 6.3

Hi,

We developed a test application in WebDynPro and created the archive also successfully.When we tried to deploy it, we were getting error at SDM(Software Deployment Manager) side.it says cannot able to connect to SDM ..SDM not running etc.We tested our SDM individually using Check Connection it gives fine message.

We are using the evaluation CD which SAP has shipped.Please help us in this regard.

Thanks

Senthil
