I was doing following guide to develop a service using Oracle Application Adapter Using Business Events

http://docs.oracle.com/cd/E12839_01/integration.1111/e10537/T430238T430579.htm

but no instance was getting created in Enterprise manager console. then i checked my Apps Adapter in Weblogic console and that was not in OK state. I had configured cluster environment and there were two SOA servers. I had to remove the target from 'cluster' and target it only to WLS_SOA1 server and then i updated and saved it and it started working fine without giving the above error.

Then again i created an Invoice (I was calling invoice Event) and instance created successfully in Enterprise manager console.
