[jboss-user] [EJB 3.0] - Java Persistence : EntityMananger Lifetime

Hi, I am new to Persistence. I would like to know is there restrictions in the declaration of EntityManger and EntityManagerFactory in the class, ie can I declare it as an instance variable or should I declare it locally on each method and after the operation performed should I close it? Is there any performance issue or any other problems in doing so? Can anybody give a solution. The solution to this will be greatly appreciated. Thanks, Sreejith View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993054#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
