Hello, I am trying to update a object over during a web service call. When I try to update I get the following error "Illegal attempt to associate a collection with two open sessions". I can insert objects into the database without a problem. Also the database mapping works correctly and updates the object if I log into the application and do the update.

Any ideas where I should be looking?

Can you try with hibernateSession.merge(object)?
I have faced the same issue but it works fine with merge.
