I have an EJB, let's call it UserEJB, lets say that it is a SLSB which returns User information. In this EJB I have a method, let's call it getUserLastName(int userID). Within this method I instantiate a POJO which fills information from a DB table. The user last name is retrieved from the POJO and returned as a String from the method.
This SLSB using a POJO business layer is standard operating proceedure in our project. When developing the business layer, we are developing the POJO mostly as the SLSB is mostly a facade.
The question is how to continue using the POJO pattern and have a simple deployment (no ear files) for development where we are able to hot deploy and avoid class loading errors?
Thanks for some hints...Point me to some links maybe?
Class loading errors depend on the usage pattern. Read about class loading in chapter 2 of the online admin/devel guide. Then read the class loading wiki pages.
