Deploy the dependent application.
Add the dependent application’s client JAR file to the calling application.
For a calling EJB component, add the client JAR file at the same level as the EJB component. Then add a Class-Path entry to the MANIFEST.MF file of the calling EJB component. The Class-Path entry has this syntax:
Class-Path: filepath1.jar filepath2.jar ...
Each filepath is relative to the directory or JAR file containing the MANIFEST.MF file. For details, see the J2EE specification, section 184.108.40.206, “Dependencies.”
If you need to package the client JAR with both the EJB and web components, set delegate="true" in the class-loader element of the sun-web.xml file.
This changes the Web Classloader so it follows the standard class loader delegation model and delegates to its parent before attempting to load a class itself.
For most applications, packaging the client JAR file with the calling EJB component is sufficient. You do not need to package the client JAR file with both the EJB and web components unless the web component is directly calling the EJB component in the dependent application.
Deploy the calling application.
The calling EJB or web component must specify in its sun-ejb-jar.xml or sun-web.xml file the JNDI name of the EJB component in the dependent application. Using an ejb-link mapping does not work when the EJB component being called resides in another application.
