Appendix B. Example code provided with WebSphere Application Server
This appendix contains information on the example code provided with the
WebSphere Application Server.
The example code discussed throughout this document is taken from a set of
examples provided with the product. This set of examples is composed of
the following main components:
- Note:
- The example code in the documentation was written to be as simple as
possible. The goal of these examples is to provide code that teaches
the fundamental concepts of enterprise bean and EJB client development.
It is not meant to provide an example of how a bank (or any similar company)
possibly approaches the creation of a banking application. For example,
the Account bean contains a balance variable that has a type of
float. In a real banking application, you must not use a float type to
keep records of money; however, using a class like
java.math.BigDecimal or a currency-handling class within the
examples would complicate them unnecessarily. Remember this as you
examine these examples.

provided with the EJB server
