## Package com.sun.messaging.jms Description

Provides additional Oracle GlassFish(tm) Server Message Queue classes for features that relate to the MQ implementation of the Java Message Service (JMS).

Oracle GlassFish(tm) Server MQ classes in this package fall into the following basic categories:

- Custom messaging functionality that is available when standard JMS objects are cast using the interfaces in `com.sun.messaging.jms`.
- Enhanced exception classes that enable the application finer grained error handling than JMS exceptions.

### Custom Messaging Functionality

Oracle GlassFish(tm) Server Message Queue provides custom message acknowledgment functionality that allows an application to acknowledge consumed messages in a `CLIENT-ACKNOWLEDGE` session with finer grained control than that available in the Java Message Service Specification.

### Enhanced exception classes

Oracle GlassFish(tm) Server Message Queue provides exception classes that enable MQ JMS clients to perform finer grained error handling than that available with standard JMS exceptions.
