Hi
Thank you for reading my post
I know that ejbRemove and ejbCreate create and remove a CMP
but what about updating a cmp ? for example i update some field and then try to store them ?
how i can do that ?
How i can have batch update and batch delete ? i mean deleting a set of records or updating a set of records?

Thank you

Hi...

ejbCreate(),ejbRemove() are life cycle methods,which are called by the container....

If u want to update the DB....create ur own method in home interface....

if u want batch updates store all queries in one file and execute it by using ResultSet.excuteBatch("");

it may help u...i too also not comfertable with cmp but i am femiliar with bmp...

ok...bye ..

You would never put any persistence code in a CMP entity bean. Look at ejbStore(). This is the method the container uses to synchronize state. For CMP you would not put any persistence code in here - it is Container Managed so let the container do its job. And, since this is a container managed method, you would not call it directly, instead it will be called implicitly it the bean is passivated, or when the transaction your updates were made in is committed.
