Your business interface should be accessible from the client. Try to include it in the classpath.

Did anyone get a solution to this problem, I dont know why this occurs, It has ruined my work a lot, can anyone help me out...

[Andrew Moko]

This is a jndi issue. I would navigate to the JNDI tree on the weblogic console and verify the bean interface mapped name

[Mahendr Shinde]

You need to add jar containing your EJB components to classpath of your client application.
