Description

Interface Summary

OnewayListener	A marker interface for components (for example, servlets) that are intended to be consumers of one-way (asynchronous) JAXM messages.
ProviderConnection	A client's active connection to its messaging provider.
ProviderMetaData	Information about the messaging provider to which a client has a connection.
ReqRespListener	A marker interface for components that are intended to be consumers of request-response messages.

Class Summary

Endpoint	An opaque representation of an application endpoint.
JAXMServlet	The superclass for components that live in a servlet container that receives JAXM messages.
ProviderConnectionFactory	A factory for creating connections to a particular messaging provider.
URLEndpoint	A special case of the Endpoint class used for simple applications that want to communicate directly with another SOAP-based application in a point-to-point fashion instead of going through a messaging provider.

Exception Summary

JAXMException

An exception that signals that a JAXM exception has occurred.

Package javax.xml.messaging Description

Provides the API for using a messaging provider to send and receive SOAP messages. This package is specified in the Java^TM API for XML Messaging (JAXM) 1.1 specification.

A client using Java^TM API for XML Messaging technology ("JAXM client") makes its connections to a messaging provider, which means that all messages it sends or receives go through the provider. The messaging provider is responsible for the delivery of messages, performing many functions behind the scenes. With a messaging provider, it is possible to send a message to multiple destinations, and a messaging provider can be configured to do the following:

• maintain a list of endpoints to which messages will be sent
• send, and if necessary, resend a message until the message is delivered successfully or until the specified limit for retries is reached
• log messages in a specified directory

In addition, a messaging provider can make it possible for a protocol such as ebXML or SOAP RP to operate on top of SOAP, extending the Quality of Service available to JAXM messages.

The API in the javax.xml.messaging package makes it possible to do one-way messaging. One-way messaging allows the client to send a message and immediately go on to other work because the response, if there is one, will be sent as a separate operation at some time in the future.

The javax.xml.messaging package must always work in conjunction with the javax.xml.soap package, which provides the API for constructing SOAP messages and retreiving their content. (The javax.xml.soap package is defined in the SOAP with Attachments API for Java^TM (SAAJ) 1.1 specification.)
