Supplied jar files

WebSphere MQ Everyplace is supplied with a set of class libraries in the form of jar files that can be used when deploying applications that utilize WebSphere MQ Everyplace. There are two types of jar file; base jar files and extension jar files. The base jar files allow a usable queue manager to be created, administered and run. The extension jar files can be used in addition to the base jar files to provide additional capability.

Base jar files

MQeBase.jar
Contains classes that provide for a basic queue manager running in client and server mode on a J2ME CDC/Foundation or J2SE or better Java runtime.

MQeMidp.jar
Similar to MQeBase.jar but for use on a J2ME CLDC/MIDP Java runtime. Allows a queue manager to run in client mode. All MIDP compliant classes are included in this jar. No extension jars can be used with this one, as they are not MIDP compliant.

MQeGateway.jar
Contains classes that provide for a basic queue manager running in client, server and bridge mode on a J2SE or better Java runtime.

Extension jar files

MQeJMS.jar
Contains the classes that extend an WebSphere MQ Everyplace queue manager to provide a JMS programming interface.

MQeRetail.jar
Contains extra classes for use in retail environments. In particular, these classes are useful on a 4690 retail system.

MQeSecurity.jar
A set of classes that are used to provide both queue and message based security. It contains a set of cryptors, compressors and authenticators.

MQeBindings.jar
This file contains all C bindings specific information. It is required if access to a Java queue manager from a C application is needed (only on Win32 platforms).

MQeMigration.jar
Contains classes that assist in migrating from an earlier version of WebSphere MQ Everyplace.

MQeDeprecated.jar
This contains all of the deprecated class files that are no longer needed by a WebSphere MQ Everyplace application. These deprecated class files help you run applications written using a previous version of WebSphere MQ Everyplace, without making any changes.

MQeDiagnostics.jar
This file helps to diagnose problems with WebSphere MQ Everyplace classes. It contains tooling to search the class path to find out the level of each class found.

Other jar files

MQeExamples.jar
A packaging of all the WebSphere MQ Everyplace examples into one jar file. This includes all of the examples supplied with WebSphere MQ Everyplace, but excludes the deprecated classes.

MQeCore.jar
This contains a minimal set of classes. On its own it is not usable but it can be used as a base for building a small footprint WebSphere MQ Everyplace system. More details on reducing footprint can be found in the "Optimizing footprint" section.
