1. Re: remove method functionality in CMP Bean
itsme Jun 6, 2008 3:57 AM (in response to mallikarjun_nbsg)Hi,
I think you are looking forpublic void ejbRemove()
for CMP Entity Beans in EJB2.x style. While you are calling the reove method on the entity bean itself, there is no need to pass in a identifier.
When calling remove via a session facade you can either first call findByPrimaryKey(id) and then call remove on that bean (has all of its ejb overhead while loading the entity from database just to remove it) or you delete it by sending an sql string right to the database direct from session facade (what prevents you from loading the entity). Then this method is a facade method that needs to be declared on the (Local/Remote) Interface of the session facade.
Hope this helps

2. Re: remove method functionality in CMP Bean
mallikarjun_nbsg Jun 6, 2008 4:50 AM (in response to mallikarjun_nbsg)Hi,
My scenario is to delete a record from the table.
I am using client and calling session facade, from session facade calling CMP Home Interface remove method by passing "primary key" value. Bean ejbRemove method is also having the same "primary key" parameter. In the method body, do I need to call set method of that primary key? do I need to write any query for this method in the ejb-jar.xml
Please help me out.
Thank you,
