Enterprise Java Computing - Applications and Architecture

Enterprise Java Computing - Applications and Architecture
By Govind Seshadri
Contributing Author: Gopalan Suresh Raj
(Chapters 7, 8 and half of 6)

Using this book, developers should be able to:

* Integrate relational databases with RMI and servlets using JDBC
* Develop sophisticated servlet-based middleware
* Design multi-tier EJB applications
* Write Jini services
* Understand advanced issues regarding RMI and Java IDL development
* Perform Java/legacy-system integration using JNI

This book empowers corporate developers to deliver mission-critical Java applications that can be deployed in the real world. With 'Enterprise Java Computing' the reader will master the critical building blocks that are necessary for developing robust client-server applications, without getting bogged down in the specifics of the Java language and its syntax.
