Overview

Packages
Package	Description
com.ibm.mq	WebSphere MQ classes for Java consist of a set classes that provide an object model that maps directly to the WMQ object model.
com.ibm.mq.constants	This package contains the Java versions of the MQ header files, which are implemented as Java interfaces which define constants used with the main MQI.
com.ibm.mq.exits	This package comprises a set of classes and interfaces which allow the Java programmer to work with MQ Channel Exits.
com.ibm.mq.headers	This package comprises a set of classes and interfaces which allow the Java programmer to work with Message Headers.
com.ibm.mq.headers.pcf	This package comprises a set of classes and interfaces which allow the Java programmer to work with Program Control Format (PCF) Message Headers (C) Copyright IBM Corporation 2012.
com.ibm.mq.jmqi	The Java Message Queueing Interface (JMQI) is the interface which represents the native MQI in the Java environment.
com.ibm.mq.pcf	This package comprises a set of classes and interfaces which allow the Java programmer to work with Program Control Format (PCF) Message Headers.

This set of JavaDoc comprises all of the API reference information for using the WebSphere MQ classes for Java. It includes what are known as the "Base Java" classes (in package com.ibm.mq) and the IBM Java implementation of the MQI (in package com.ibm.jmqi), together with interfaces containing the constants used in these APIs (in package com.ibm.mq.constants).

To use Client Exits in Java applications, the package com.ibm.mq.exits is needed.

There are also specialised classes to handle message headers in package com.ibm.mq.headers, including classes for PCF processing in package com.ibm.mq.headers.pcf.
