Not Run first project in J2EE, the Calculator Application

23 Views

I created my first project in J2EE, the Calculator Application. I followed tutorial the available one all in: http://help.sap.com/saphelp_nw04/helpdata/en/7d/cf0c8abcc34594ba9d3bbd5dd22155/frameset.htm

I obtained to publish the application but when I was to execute gave the following error:

Details: java.lang.InstantiationException: ID018236: Cannot instantiate bean. java.lang.ClassNotFoundException: class com.sap.examples.calculator.beans.CalcProxy : java.lang.Exception: Error instantiating Calculator EJBcom.sap.engine.services.jndi.persistent.exceptions.NamingException: Exception during lookup operation of object with name webContainer/applications/sap.com/CalculatorEar/Calculator/java:comp/env/ejb/CalculatorBean, cannot resolve object reference. [Root exception is com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Object not found in lookup of CalculatorEjb.]
