Error from ejbc on stateless session bean

[Srinivas Bitla]

Hi All,
This is the error I am getting when I try to build my application in weblogic 8.1. I am certain that my EJB Facade meets all the requirements that were complained in the error message, but still no clue what is going wrong. Any one have any idea?
