    Hi,
    I am getting problem while doing the ejbc of my jar files. My jar file contains all three class files and the ejb-jar.xml.My bean is a cmp one. It is having a primarykey class. Here are my doubts:
    1. Is it necessary, in CMP bean, to return the PrimaryKey class from ejbCreate Method? ( As I got from Roman book that as the bean is CMP, it should return void. But during ejbc I am getting error )
    2. Is the implementation of haseCode and equals methods are must?
    3. Here is my ejb-jar file. Let me know whether there is any problem with this.
