An error when deploying EJB.. is this a bug.

[praveen]

Hi all,

I am trying to deploy a BMP EJB.

I am getting this following exception.


Section: 9.2.9
Warning: The primary key class must override equals().


I have implemented the equals method in my PK class..

And here the implementation code..

public boolean equals(MyBMPPK other) {
 return ( this.MY_ID.equals(other.MY_ID)
 && this.MY_ID2.equals(other.MY_ID2) );

}

I appreciate any help in fixing this problem.

Try to do it like this:

public boolean equals(Object other){
if(other instanceof MyBMPPK){
MyBMPPK otherpk = (MyBMPPK)other;
if(otherpk.MY_ID.equals(this.MY_ID) && otherpk.MY_ID2.equals(this.MY_ID2))
return true;
else return false;
}
return false;
}

In fact u didn't override the equals method 'cause the signature is
public boolean equals(Object other) and u used
public boolean equals(MyBMPPK other)

I think your problem is that you've overloaded the equals method, not overridden it.

It should be declared as:

public boolean equals(Object other)
{
 if(other instanceof MyBMPPK)
 return ( this.MY_ID.equals(((MyBMPPK)other).MY_ID)
 && this.MY_ID2.equals(((MyBMPPK)other).MY_ID2) );
 else
 return false;
}

Note the argument to the method.

Hope this helps,
