Example Code

JServer comes with approximately forty EJB and CORBA sample programs. These brief examples demonstrate all the major features of the product, including:

• database access using both SQLJ and JDBC

• security

• session management

• transaction control

The examples come complete and ready to run, including a UNIX makefile and Windows NT batch file to compile and run each example. All you need is a Java-enabled Oracle8i database with the standard EMP and DEPT demo tables for some of the examples, and you can run the examples right out of the box.

The emphasis in these short examples is on demonstrating features of the ORB, EJBs, and CORBA, not on elaborate Java coding techniques. Even Java novices will be able to understand these examples with only brief study.

In addition to these sample programs, there are longer demos that show more complete examples, including a sample Web-based application (World-o-Books) and an example (acctMgmt) that uses several objects and is implemented using both EJBs and CORBA, so that you can contrast the two models.

The example and demo code is available on the distribution Compact Disc. See the README file that comes with JServer for the location and name of the archive file that contains the examples. Most of the examples include a README file that tell you what files the example contains, what the example does, and how to compile and run the example.
