What are WebSphere MQ classes for Java?
WebSphere MQ classes for Java (also referred to as WebSphere MQ base Java) allow a program written in the Java programming language to: Connect to WebSphere MQ as a WebSphere MQ client. Connect directly to a WebSphere MQ serverWebSphere MQ base Java enables Java applets, applications, and servlets to issue calls and queries to WebSphere MQ. This gives access to mainframe and legacy applications, typically over the Internet, without necessarily having any other WebSphere MQ code on the client machine. With WebSphere MQ base Java, Internet users can become true participants in transactions, rather than just givers and receivers of information.
What are WebSphere MQ classes for Java Message Service?
WebSphere MQ classes for Java Message Service (also referred to as WebSphere MQ JMS) is a set of Java classes that implement Sun’s Java Message Service (JMS) interfaces to enable JMS programs to access WebSphere MQ systems. This book describes an implementation of Version 1.1 of the JMS API specification, which is backwards compatible with Version 1.0.2b. Any features of the implementation that apply only to Version 1.1 of the specification, and not to Version 1.0.2b, are clearly marked. Both the point-to-point and publish/subscribe models of JMS are supported. Using WebSphere MQ JMS as the API to write WebSphere MQ applications has a number of benefits. Some advantages derive from JMS being an open standard with multiple implementations. Other advantages come from additional features that are present in WebSphere MQ JMS, but not in WebSphere MQ base Java. Benefits arising from the use of an open standard include: The protection of investment, both in skills and application code. The availability of people skilled in JMS application programming. The ability to plug in different JMS implementations to fit different requirementsSun’s Web site at http://java.sun.com provides more information about the benefits of the JMS API. The extra function provided over WebSphere MQ base Java includes: Asynchronous message delivery. Messages can be delivered to an application as they arrive, on a separate thread. Message selectors. Support for publish/subscribe messaging. Structured, more abstract, message classes. Implementation details are left to the JMS provider.
