portal ear deployment p4 port error

Hi

I have developed a portal application project. After which I exported that

project to the corresponding EAR file.

Now comes deployment part , when i tried to deploy that EAR file on SAP AS JAVA

It showed me error :

Cannot obtain deployment client.

Cause: Selected p4 port -1 is not reachable. Posssible solution is to use p4 SSl port 50306, which is reachable.

Kindly suggest any solution to the above mentioned problem.

Thanks
