Capture the benefits of asynchronous logging
Develop an asynchronous log service using JMS and Hibernate
This article will help you develop a simple log service. The service creates some log messages, sends them across the network to a JMS provider,
Tutorial Details:
Hibernate is an open source product that eliminates JDBC coding. It is a tool for object-relational (OR) mapping within Java environments. It creates a mapping between Java objects and database entities. Object-relational mapping is a key requirement in enterprise projects. The data produced or changed as a result of processes must be persisted. Persisting data can turn into a nightmare for developers, especially if the data model is always changing the user requirements. Hibernate can alleviate complications resulting from data persistence. Refer to Resources for more information on Hibernate. The log service framework we develop in this article uses Hibernate as a medium for OR persistence.
Enterprise messaging
J2EE continues to mature with respect to distributed computing environments. We can leverage many of its features, such as JMS, to develop asynchronous services. JMS is a specification from Sun Microsystems and its partners that covers inter-application messaging standards. See Resources to download the specification. Third-party vendors implement the specification defined by Sun. JMS is designed to handle different message types without the messages having knowledge of each other.
Remote procedure call (RPC) models such as RMI (remote method invocation), SOAP (Simple Object Access Protocol), and ORB (object request broker) are interface-centric, meaning the publisher expects a return value. In the case of JMS, the sender has no knowledge of the receiver. The applications that send and receive messages do not communicate via a standard communication channel. In fact they delegate the responsibility of delivering the messages to the JMS provider. The applications\' jobs are completed when they post a message to the destination.
