Fred:
Sorry about that. Actually, the JNDI name "PersonBean" is bound correctly.
The file breakdown is simplified... Your suggestion is a good one. However,
I am concerned I will get the same error if I deal with a Session bean
instead than with an Entity bean. For some reason, if I add the
ClientJAR.jar to the Tomcat lib directory everything works fine...

communication
The jndi name "PersonBean" is bound to a com.munoz.concept.person.PersonHome
rather than a com.munoz.ejb.person.PersonHome. Perhaps a build problem?
It is preferable to insulate JSP from EJB. Wrap the Entity EJB calls in a
Session EJB. Wrap the Session EJB in a bean. Call the bean from the JSP.
Remove the EJB classes from the war. Cf. Sun J2EE blueprints for examples.
