Hello Guys,
When I update a record using Hibernate and Struts, I have to transfer primary
key(type is LONG) to ModelUpdadteAction class from update.jsp file.
In ModelUpdateAction.java file:
String v_id = request.getParameter("modelid");
Long v_idLong = Long.valueOf( v_id);
Models model = new Models();
model.setModelId(v_idLong);
model.setModelname("Update New record IN Models");
ModelsDAO modeldao = new ModelsDAO();
modeldao.update(model);
I cann't update the record. A error is: javax.servlet.ServletException: a
different object with the same identifier value was already associated with the
session:
If I directly update with a primary key:
Long v_idLong = Long.valueOf( "55");
Models model = new Models();
model.setModelId(v_idLong);
model.setModelname("Update New record IN Models");
ModelsDAO modeldao = new ModelsDAO();
modeldao.update(model);
It is successful.
Please reply that is what is problem and how to solv it. Thank you.
