hard to say what goes wrong.

The only possible problem I saw: the field "dealerNo" does not contain a @Column annotation:
private int dealerNo;

So maybe this field is not set synchronized with the database, so that your "getDealer" method does not find anything and the client creates a new entity?

If this does not help: please post the code snippet of your client.
It might also help to activate SQL logging in persistence.xml and take a look at the SQL statements. You should find an insert statement instead of an update there.

Hope this helps
