Cant able to edit Interactive forms in NWDS and how to create .xsd files

Hi all,

I am trying to develop Offline Interactive forms using webdynpro for Java with BPM, for this i am Using NWDS as IDE but i cant able to edit interactive forms in it and it is giving me an error like "Class ID not found in registry" i think this is because of compatibility

My NWDS is -->SAP NetWeaver 7.2 SP03 PAT0004 and

ALD that i am using -->Designer9.0

After installing ALd do i need to do any manual configuration to embed with NWDS

Please help me in this issue and also i have a doubt in my mind like is there any possibility to generate .xsd file other than webdynpro perspective if yes please give me some hints on it so that i will embed my adobe forms through BPM directly from ALD instead of going through webdynpro java

Thanks
