DB2 for z/OS and OS/390: Ready for Java

An IBM Redbooks publication




Abstract

The earth is flat!
The earth is the center of the universe!
Men shall never fly!
Java will never work properly on the mainframe!

All four statements had a lot of advocates for a long time, but all of them turned out to be wrong.

In this IBM Redbooks publication we show how Java and DB2 for z/OS and OS/390 can work together and form a strong combination that can run your mission-critical enterprise applications. This publication focusses on the new IBM Universal Driver for SQLJ and JDBC, IBM’s new JDBC driver implementation, supporting both Type 2 and Type 4 driver connectivity to the members of the DB2 family, including DB2 for z/OS, and DB2 for Linux, Unix and Windows.

This publication provides guidance on the different ways to set up your environment to hook a Java program up to a DB2 for z/OS subsystem, through JDBC or SQLJ, using the Type 2 driver and the Type 4 driver.
We provide an SQLJ tutorial, and demonstrate how to develop and deploy SQLJ programs using the new SQLJ support functions that became available with WebSphere Studio Application Developer V5.1.
We demonstrate the use of Java and DB2 using native Java programs, as well as through the use of Servlets and JSPs running on a WebSphere Application Server.
