From the founding editor-in-chief of 'Java Report Online' comes advanced information on JDBC, servlets, JNI, RMI, Java IDL, and EJBs - the basic building blocks of any significant corporate business application. Enterprise Java Computing is the ideal hands-on reference, not only for mastering these cutting-edge concepts, but also for gaining hard knowledge on practical design and deployment issues. 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.
