    Hi !
    I use weblogic 5.1. I've created jar file manually. But when I try to generate container classes using ejbc, I get the following error:
    ERROR: Error from ejbc: [9.2.9] In EJB Test, the primary key class must implement the method public int hachCode()

    ERROR: Error from ejbc: [9.2.9] In EJB Test, the primary key class must implement the method boolean equals <Object other>.
    ERROR: ejbc found errors.

    Then I included the two methods in my Primary class files ()returning 0 and false). But still I get the same errors.
    Could any one help me out regarding this problem. It is very urgent.

    Thanx
    AJP

    hi
    see the primary key class must implement hashcode and equals object method
    so u must ev these methods dclared in ur class
    than compile this class first remove previous class file
    now run ur bean

    Hi !
    This is my Primary key class. Still I get the problem.

    import java.io.Serializable;
    public class TestPK implements Serializable
    {
        public TestPK(){}

        public int hashCode()
        {
            return 0;
        }
        public boolean equals(Object obj)
        {
                return false;
        }
    }

    Thanx.

    Hi,

    Change u'r PK file as follows:

    public class TestPK implements java.io.Serializable
    {
        public int id;
        public TestPK(){}


        public int hashCode()
        {
            return id;
        }
        public boolean equals(Object obj)
        {
            if(obj instanceof TestPK)
            {
                return (id == ((TestPK)obj).id);
            }
            return false;
        }
        public String toString()
        {
           return String.valueOf(id);
        }
    }

    Hope it should work now.

    Regards
    Saran
