Developing Mainframe Java Application

As simple Web access to data housed on corporate mainframes is fast becoming a core business requirement, mainframe programmers need to learn how to develop Java applications to keep pace with growing corporate needs. With its accessible and reader-friendly approach, this book offers step-by-step guidance on how to use Java to access file and database structures common to mainframe environments. Java expert Lou Marco begins by explaining how Java compares to mainframe languages such as COBOL and PL/I. He presents Java code snippets along with COBOL and PL/I snippets that perform the same function so you can gain a better understanding of Java mainframe programming. As you examine these snippets, you'll also learn how to build a complete Java application using the Sun Java Development Kit. Marco then goes on to cover Java implementations for IBM's OS/390. You'll find out about specific packages such as CICS for transaction processing, IMS for transaction processing and hierarchical databases, DB2 for relational databases, and VSAM for sequential and indexed direct access. And he provides you with advanced Java programming techniques, including Java, RMI, and servlets.

A must-read for anyone who needs to provide users with access to business data via a Web interface, this book:

• Shows you how to create your first Java program
• Explains how to define and declare data
• Includes methods on encapsulating and hiding data
• Discusses inheritance, interfaces, and event handling
• Covers the training department class scheduler application
• Describes how to create applets
