114 e-<strong>business</strong> <strong>Application</strong> <strong>Solutions</strong> on OS/390 Using Java Vol. I
Part 3. Develop <strong>Application</strong> <strong>Solutions</strong> for OS/390 Using Java In this part we describe various application solutions using Java and a specific subsystem on OS/390. All solutions make use of a Webserver, Lotus Domino Go Webserver Release 5.0 with either ServletExpress or WebSphere <strong>Application</strong> Server for OS/390 V1.1. For each subsystem we focus on a different element: In Chapter 9, “DB2 Access” on page 117 we focus on programming servlets using either JDBC or SQLJ to access DB2. In Chapter 10, “Develop Java <strong>Solutions</strong> for CICS on OS/390” on page 155 our starting point was a Windows NT workstation with a development environment including a CICS server (TxSeries) and a Webserver. We developed an application entirely on Windows NT, ran it there, and then moved the application up to OS/390. In Chapter 11, “Accessing IMS Transactions from the Web” on page 207 we focus on a more complicated scenario to access IMS: using the session concept. Also, we developed a solution using the MQSeries Bindings for Java on OS/390 to access IMS from a Java servlet or JSP. © Copyright IBM Corp. 1999 115
