I don't really understand what you are asking. Can you be much more specific?
I am trying to retreive valuse from database to JSP on load that is when that JSP is called i need to invoke a method which takes care of retreving all the values from the database and display it. How is it possible in CMP(JBoss) and also pl tell me what all changes I need to make in ejb-jar,jwas,etc. Hope u got my question
This is way to generic of a question. I would suggest that you read a general book on J2EE. If you search the Internet, you will find several quick how-to.
