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.
