Hi Forum! Till now I have had not a single reply to my query. Please, can somebody reply with an answer? I am stuck on this CMP.
It looks like the book used CMP 2.0, which is only supported in JBoss 3.0. To activate the CMP 2.0 engine in JBoss 3.0 you ejb-jar.xml file must have the EJB 2.0 DOCTYPE declared.
