Fail to lookup entity bean inside a stateless session bean b

[calsonli]

Hi all,

I am using JBoss 4.0.5 GA and myEclipse 5.1.1 GA to do a web project with EJB for database manipulation.

I created a stateless session bean which is invoked in doGet method of a servlet. I tried to add CMP entity bean lookup method in a business method of this session bean. It ends up with a "Naming Exception". The code snippet inside the business method of stateless session bean is as follows.

try {
// StaffLocalHome is the home interface of CMP entity bean Staff
StaffLocalHome staffHome = StaffUtil.getLocalHome();
StaffLocal staff = staffHome.findByPrimaryKey(new StaffPK(loginID));
StaffData staffData = staff.getValueObject();
....
catch (NamingException ne) {
returnCode = 1;
}
catch (FinderException fe) {
returnCode = -2;
}
catch (Exception e) {
returnCode = 2;
}
...

If I moved the above codes inside the servlet where stateless session bean is invoked, no problem of naming exception when looking up CMP entity bean. So, it seems that ejb-jar.xml, jboss.xml, web.xml and jboss-web.xml are correctly configured.

Could you advise where the problem is?

Thank you,
Calson

what's the lookup code look like?

you should be able to use:

@EJB
MyBeanLocal bean;

to inject the slsb.

Thanks a lot for your reply, Waynebaylor.

My lookup code is as follows, which is generated from XDoclet.

/**
 * Utility class for Staff.
 * @xdoclet-generated at ${TODAY}
 * @copyright The XDoclet Team
 * @author XDoclet
 * @version ${version}
 */
public class StaffUtil
{
 /** Cached local home (EJBLocalHome). Uses lazy loading to obtain its value (loaded by getLocalHome() methods). */
 private static ts.interfaces.StaffLocalHome cachedLocalHome = null;

 private static Object lookupHome(java.util.Hashtable environment, String jndiName, Class narrowTo) throws javax.naming.NamingException {
 // Obtain initial context
 javax.naming.InitialContext initialContext = new javax.naming.InitialContext(environment);
 try {
 Object objRef = initialContext.lookup(jndiName);
 // only narrow if necessary
 if (java.rmi.Remote.class.isAssignableFrom(narrowTo))
 return javax.rmi.PortableRemoteObject.narrow(objRef, narrowTo);
 else
 return objRef;
 } finally {
 initialContext.close();
 }
 }

 // Home interface lookup methods

 /**
 * Obtain local home interface from default initial context
 * @return Local home interface for Staff. Lookup using COMP_NAME
 */
 public static ts.interfaces.StaffLocalHome getLocalHome() throws javax.naming.NamingException
 {
 if (cachedLocalHome == null) {
 cachedLocalHome = (ts.interfaces.StaffLocalHome) lookupHome(null, ts.interfaces.StaffLocalHome.COMP_NAME, ts.interfaces.StaffLocalHome.class);
 }
 return cachedLocalHome;
 }
}

Thank you,
Calson

what's the code in the servlet that does the lookup for the first session bean?

and is the NamingException from StaffUtil or from the servlet?
