EJB 3 on Weblogic throwing exception on server start-up

[vikas sharmaa]

I am not able to deploy EJB 3.0 in my existing application. I am using Weblogic 10.3.

code:

@Remote
public interface Channel {

	public String postReportingRequest();
}

@Stateless
public class ChannelBean implements Channel {

	public String postReportingRequest() {
		return "success";
	}
}

weblogic-ejb-jar.xml:

<!DOCTYPE weblogic-ejb-jar PUBLIC '-//BEA Systems, Inc.//DTD WebLogic 8.1.0 EJB//EN' 'http://www.bea.com/servers/wls810/dtd/weblogic-ejb-jar.dtd'>

<weblogic-ejb-jar>
	
	<weblogic-enterprise-bean>
		<ejb-name>ChannelBean</ejb-name>
		<jndi-name>Channel1</jndi-name>
	</weblogic-enterprise-bean>
	
</weblogic-ejb-jar>

ejb-jar.xml is optional in EJB 3.0, so I have removed it.

I am getting below error on starting Weblogic application server:

<Sep 14, 2012 7:35:28 PM IST> <Error> <J2EE> <BEA-160197>
