The course is designed to provide the skills necessary develop and test OO Cobol and Java programs which interact with each other on z/OS systems. A complete look at the features and facilities provided by the various z/OS components in support of this type of processing will be provided.

The major areas of focus will be providing an understanding of the effort necessary to allow OO Cobol and Java programs to call one another, pass information between programs and work with common facilities such as XML and SQL. Other topics, such as HTTP servers and WebSphere MQ, will be lightly covered as required to provide a more complete, real world feel for the workshops. However, the students will not require an in depth knowledge of some of the supporting facilities, only a basic understanding of the terminology.

The course begins with an overview of the principle languages facilities utilized throughout the course. Next the course covers the z/OS components UNIX System Services and HTTP Servers as they relate to application implementation. The next portion of the course covers common data representation through facilities like Unicode and XML. Finally, some debugging and problem solving information will be provided.

Students are encouraged to bring both current and planned application design specifications with them to class to provide for discussion. It is also recommended that application database and/or file layouts be included within the information to assure a more accurate understanding of how this data will be impacted by the topics discussed.

This course is intended for application developers and other information systems personnel.

This course will provide the knowledge base for implementation of OO Cobol and Java program interactions on z/OS systems. Upon completion of the course, the student will be able to:

• Describe the key related features and facilities available within OO Cobol.
• Describe the key related features and facilities available within Java on z/OS.
• Describe, explain and better understand the functions provided by z/OS components like USS and HTTP Servers.
• Describe, explain and better understand the facilities provided by components like Unicode and XML.
• Gain a basic knowledge of the storage capabilities used in support of these applications.
• Gain a basic knowledge of the debugging and management facilities provided by z/OS in support of these applications.

• Brief Introduction to UNIX System Services (USS)
• Brief Introduction to Object Oriented Programming Technology
• OO Cobol
• Java
• Brief Introduction to HTTP Servers
• Unicode
• Brief Introduction to HTML and XML
• Debugging

It is highly recommended that students have obtained the knowledge and skills provided by classes or otherwise obtained for the following topics:

• Basic understanding of Client/Server, HTTP Server and WebSphere MQ environments and terminology
• Have at least 1 year of application programming experience in Cobol and/or Java
• Have at least a general knowledge of TSO, z/OS functionality and supporting features such as JCL and utilities
