[jboss-user] [EJB 3.0] - Invoking session object from other web application

[uagardx]

I am new to EJB3. Created a new EJB3 TRAIL project in eclipse and deployed one stateless session bean. I created a client jsp in the same Trail project and deployed Trail.ear in jboss default directory. It went well and successfully invoked the session bean from client. Next I create a dynamic web project WebTest and copied the client jsp code from Trail application to the web project, then i created a WebTest.war file and deployed that in same jboss server where my Session bean is deployed in Trail application. I got the following error while i Invoke JSP client of WebTest project. Do i need to include any other jars in my webproject as The EJB is deployed in other application??
