Chapter 4: Creating Enterprise JavaBeans Components and Clients

Define the Glossary entity bean

We will define the entity bean by first creating the bean interface and implementation classes in Java, then importing the classes into EAServer Manager. Importing the classes creates the EJB component and defines the IDL interfaces required for it to run in Jaguar and be invoked by clients.

StepsCreating the entity bean classes

  1. Under the EAServer java/classes directory, create the following subdirectory structure:

    Sample/Intro/Glossary

  2. Copy the following files from the html/docs/tutorial/ejb directory of your installation to the java/classes/Sample/Intro/Glossary directory:

  3. Compile these classes using a JDK 1.3 or later compiler, for example, on UNIX:

    cd $JAGUAR/java/classes/Sample/Intro/Glossary
$JAGUAR/bin/jc Glossary*.java

    Or on Windows, in a Command window:

    cd %JAGUAR\java\classes\Sample\Intro\Glossary
%JAGUAR%\bin\jc Glossary*.java

StepsImporting the entity bean classes into EAServer Manager

  1. In EAServer Manager, click on the Tutorial package.

  2. Select File | New Component.

  3. In the Component wizard, select Import From EJB Class File. Click Next.

  4. In the Component wizard - CLASSPATH screen, click Next. No changes are required to the default CLASSPATH to import our classes.

  5. In the Component wizard - Import EJB Class Files screen, enter the values below:
