a copy of error
ERROR: Error from ejbc: [9.2.9] In EJB romanbm, the primary key class must imple
ment the method boolean equals(Object other).
ERROR: Error from ejbc: [9.2.9] In EJB romanbm, the primary key class must imple
ment the method public int hashCode().
ERROR: ejbc found errors

add the follwing methods to ur pk class. the pk class i presume may have some variable called accountID.


public int hashCode() {
return ((accountID).hashCode());
}

public boolean equals(Object obj){
if(!(obj instanceof AccountPK))
  return false;
if( (accountID.equals(((AccountPK)obj).getAccountID())) )
return true;
else
return false;
}

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. This is my primary key class :

package hitachi.buyplan;
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,

Make u'r code as follows:
public class TestPK implements Serializable
{
    public TestPK(){}
    public int id;
    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 now it will work
