Java Application Strategies for iSeries and AS/400

Java Application Strategies for iSeries and AS/400, Second Edition provides a much-needed look at the realities of using Java to develop real-world OS/400 applications. Don Denoncourt draws on his years of experience as a business application programmer and on his acknowledged expertise in Java to lead RPG programming professionals through the potential pitfalls of object-oriented programming (OOP), teaching them effective strategies for Java application design and programming.

Covering the gamut of Java application strategies, this book includes introductory information on Java and object-oriented programming, methods for integrating object-oriented techniques into your application design, a description of the utilities and tools available on iSeries and AS/400, methods to access DB2/400 with Java, ways to integrate Java with your legacy applications, and a tutorial on how to develop a Java GUI.

New to this edition are sections on server-side Java and the Web--an up-to-date look at servlets, JavaServer Pages (JSPs), and programming server-side applications on the Web.

Upon completion of Java Application Strategies for iSeries and AS/400, you will be able to:

• Use industry-standard SQL to manipulate and report on your AS-400 data
• Understand both the structure and the intent of the Java programming language
• Determine why Java applications developed with RPG structure techniques fail
• Understand the benefits and caveats of each of the three Java application architectures
• Recognize the three phases of OOP: encapsulation
• inheritance
• and polymorphism
• Apply standard OO strategies for the development of OS-400 Java applications
• Create hierarchies of Java classes using OO inheritance
• Encapsulate business entities that are stored in DB2 into Java classes
• Create Java GUIs using the Abstract Window Toolkit (AWT) components of Java 1.1
• Create robust GUIs with components of Java 1.2's Java Foundation Classes
• Use the Java GUI replacement strategy for the highly successful subfile paradigm
• Access DB2 data using record-level access
• Interoperate Java applications with RPG and COBOL programs
• Access DB2 data using Java Database Connectivity (JDBC) and Java SQL interface
• Properly handle Java errors and create application-specific Java error classes
• Use the Java language's superior strategy for documenting code
• Use Java servlets and JSPs to develop powerful server-side Web applications
• Develop a Model-View-Controller (MVC) strategy
• Combine JSP
• HTML
• servlets
• Java Beans
• and your legacy RPG programs
