[P-298 Of EJB3 In Action Book] States: In the diagram, it shows that using a refresh method a detatched entity can become managed..
[P-332Of EJB3 In Action Book] States: The refresh method only works on managed entities...
Aren;t the above 2 statements contradictory? Moreover Statement1 is incorrect...

Hi Sandeep Vaid..

As far as i know the EntityManager.refresh() used to get the last state of the entity.. (its mean that the Detatched entity will become Manage entity...)..

Thanks..


Sorry, perhaps my english language isn't too good.. Prepare for SCJP 6, Please God help me.. ☼

Sandeep,

We have already asked you on earlier occasions, not to ask the same question in multiple forums. I am going to close this one. Let the discussion be continued in your other thread here http://www.coderanch.com/t/472072/Object-Relational-Mapping/java/EntityManager-refresh-works-only-managed
