Deploying EJBs Overview

Restriction: This topic applies only when the Enterprise Server feature is enabled.

An EJB running a COBOL service runs in two places: the COBOL service runs under an enterprise server, and the EJB and client run under a third party Java EE application server, such as WebSphere or WebLogic.

You deploy the COBOL service from the .car file.

You deploy the EJB and client by deploying the following to a Java EE application server:

The enterprise archive file myservice.ear. This file is created automatically when you generate a Java client. The file contains the:
- EJB archive file myservice.jar. This file is created when you generate a client and also when you use the Deploy tool to deploy the service interface.
- Client archive file myservice.war. This file is created when you generate a client.
If you haven't generated an .ear file, but have only the .jar file, you might be able to deploy the .jar file instead. Your Java EE application might require you to package the .jar file into an .ear before deploying it, or you might find it simpler to do that.
One of the supplied resource adapters, mfcobol*.rar. A resource adapter enables the EJB to communicate through its Java EE application server with an enterprise server. Resource adapters are also known as Java EE connectors and they are packaged in resource archive (.rar) files.

Many Java EE application servers are supported, such as WebLogic and WebSphere. Each application server has different deployment requirements and different utilities to help.
