My next project involves EJB and I am trying to quickly ramp up. I am going thru some books but I need how to do this very basic thing...... a) Assume that we are trying to transfer funds at an ATM machine from the checking account to savings account. So in this case, let's say, Transaction Manager is a Session object and Account is a Entity bean. Could somebody please show me how the transaction and exception handling code for this operation looks like. I am basically interested in the method which handles the transaction. b) In the above scenario, what are the high level steps needed to implement the JSP to create an HTML interface. c) Does EJB have any security mechanism which authenticates the requestor? Thanks in advance! Sarah
