I want to keep a HashSet of  Instances of a user class which contains a
javax.ejb.HomeHandle.
for that I created a HashSet like this.

private static final HashSet evaluators = new HashSet();

My class looks approx. like this

public class TradedQoSEvaluator implements java.io.Serializable
{
 protected HomeHandle homeHandle=null;

 public TradedQoSEvaluator(HomeHandle homeHandle)
 {
  this.homeHandle=homeHandle;
 }

I read that the HashSet (just as Set) uses the equals method to determine
whether or not an object is already in the HashSet.
So I overloaded the equals method of Object in my class with

 public boolean equals(Object otherObject)
 {
  if (this.getClass()==otherObject.getClass())
  {
   /** @todo We have to find out how we can compare two HomeHandles?  */
   //TradedQoSEvaluator other=(TradedQoSEvaluator)otherObject;
   //return homeHandle.equals(other.homeHandle);
   return true;
  }
  return false;
 }
}

Why is my method never called, neither when I invoke add() nor when I invoke
contains() is my method called.
Or put in other words, how can I prevent that two instances which both
contains a HomeHandle pointing to the same EJBHome are only added once to
the HashSet.
How can I find out if two HomeHandle point to the same EJBHome interface,
and how can I make my HashSet to reflect this.

Thanks for any help
