This chapter describes how Enterprise JavaBeans (EJB) technology is supported in the Oracle GlassFish Server.
The following topics are addressed here:
For general information about enterprise beans, see Part IV, Enterprise Beans, in The Java EE 6 Tutorial.
Note - The Web Profile of the GlassFish Server supports the EJB 3.1 Lite specification, which allows enterprise beans within web applications, among other features. The full GlassFish Server supports the entire EJB 3.1 specification. For details, see JSR 318.
The GlassFish Server is backward compatible with 1.1, 2.0, 2.1, and 3.0 enterprise beans. However, to take advantage of version 3.1 features, you should develop new beans as 3.1 enterprise beans.
