I am not sure if this will answer what you are asking, but I'll give it a try. The application server normally provides an EJB container and a JSP container and allows for you to change appropriate settings to let EJBs and JSPs communicate with one another. At that point, you can have Java directly in the JSP (or in a JavaBean used by the JSP) access EJBs as normal Java code does (getting the home interface, etc.).
Dustin, is absolutely correct Venkat, you would need to remember that JavaBean is acting as a client to your EJB, for your JSP.You will have to get the instance of the HomeObject to create an instance of EJBObject in your JavaBean later in your code, to access the EJB. The following sample code might be helpful to you.
