Hi, Please refer to the following Mock test questions from the HFEJB book EntityBean synchronization chapter: Q 9 - B Are you sure? I thought u cant invoke getEJBObject() from entityContext inside the ejbCreate() method. EntityBean relationships chapter: Q 12 - D Are you sure? I thought "Select Object(o) from Ordfer" would give you all the orders irrespective of whether they have line items or not. ________________________________________ Other doubts in EntityBean relationships chapter: Q 13 - B Its possible I guess that path exporessiuons may end in CMR fields. Would this be in the select or in the where? Q 17 - A What do u mean by "the_single_valued_path_expression must have a string value"?
