I have following code does creating. If catch SQLException for insert a duplicate key which defined by database, does another creation avoid the same key value.
try{
myHome.create(a);
}
catch(SQLException e)
{
myHome.create(b);
}

The second creation does not work fine. Check log file it says:
javax.ejb.CreateException: Error checking entity exists: No results were returned by the query.

It dose not work too even I lookup a new home in catch block.

Anybody has idea what is the problem?
