Use the steps in this task to develop EJB 2.X enterprise beans.

  • EJB 2.0 module considerations

    When you are using Enterprise JavaBeans (EJB) 2.0 modules, keep in mind the following considerations.

  • Create stubs command

    For Enterprise JavaBeans 1.X or 2.X modules that are in a Java™ EE 7 application, the createEJBStubs command must be used to create stub classes for remote interfaces of Enterprise JavaBeans (EJB) beans packaged in Java archive (JAR) or Enterprise archive (EAR) files. It also provides an option to create a single stub class from an interface class located in a directory or a JAR file. Several command options are provided to package the generated stub classes in different ways. See the Syntax and Examples sections for more details.
