Problem while generating business process

Hi,
I am trying to set up the webMethods RosettaNet Solution. I have installed Integration Server65, My webMethods Server70, Modeler651, RosettaNet Module601 and Trading Networkds65. I have created the trading partners in TN and have imported the sample par files in RosettaNet. I have configured logical server in WmAdmin, and mapped to physical server also. I have imported the Process Models for PIP3A4 in Modeler and while generating the Business Process am getting the following error.

Generating implementation for “Pip3A4 Buyer Model”

Validating process model “Pip3A4 Buyer Model”…
- If correlating, make sure to assign correlation service to potential start nodes…
- Unable to clean up last generated PRT fragment on logical server “Design Server”. This logical server is not defined or does not have a physical server mapping.

Generating flow services for “Pip3A4 Buyer Model”…
“Wait for Internal PO Request” : Generating flow service…
“startNOF” : Generating flow service…
“Inbound Map” : Generating flow service…
“Send Receipt ACK” : Generating flow service…
“Done” : Generating flow service…
“OutboundMap” : Generating flow service…

“Error” : Generating flow service…
“Wait for Exception” : Generating flow service…
“Verify ACK” : Generating flow service…
! Error: Integration Server invoke: Exception = java.lang.reflect.InvocationTargetException: nodb

“Pip3A4 Buyer Model” generation failed with 1 errors.

Any suggesions in this regard will be very helpful.
Thanks,

After you configured logical/physical server did you restarted the IS?? Try after restart…
