Cannot download WSDL from http://portal:50200/AdobeDocumentServices/Config?

Dear All,

I have installed SAP EP 7 on Window Platform AS JAVA, but after post installation when I tried to access

http://portal:50200/AdobeDocumentServices/Config

I got this message

Cannot download WSDL from http://portal:50200/AdobeDocumentServices/Config?wsdl: Cannot connect to http://portal:50200/AdobeDocumentServices/Config?wsdl: portal

I installed only java stack, why I am getting this error? Do I need to install ABAP stack also to use Adobe Forms??

Please clear my doubt.

Thanks in Advance
