Appendix D. Reflection and dynamic instantiation
Overview
This appendix describes, as succinctly as possible, the use of the Java ‘reflection’ API. While EJB implementations do not usually use reflection extensively, the EJB container does; an understanding of reflection will help to understand why the interaction between the EJBs and the container has the form it does. In addition, with an understanding of reflection you can write some utility programs that will be of use in EJB development. For example, it is not very difficult to write a program that uses reflection to inspect an EJB’s interfaces and generates a template for the implementation class dynamically.
