The embedded JMS provider is a scaled-down version of
WebSphere MQ 5.3 and is installed with WebSphere 5.0. It is meant to be
used only internally by applications running on WebSphere Application
Server. Messaging into or out of the WebSphere environment is not
supported and is a violation of the WebSphere Application Server license
agreement.. The full WebSphere MQ product is needed for messaging that is
external to WebSphere..
Messaging external to the WebSphere environment includes:
- Application clients running on machines that are remote to
WebSphere
- WebSphere applications on remote machines
- Any application not running within WebSphere
These applications cannot use the embedded JMS provider. Messaging that is
internal to WebSphere, and is supported with embedded messaging, includes:
- Applications running in WebSphere
- Application clients on the same machine as WebSphere
A WebSphere node within the same administrative domain as the node on
which embedded messaging is installed can also use the embedded JMS
provider. This is possible by federating both nodes to the same cell using
WebSphere Application Server Network Deployment.
The full WebSphere MQ 5.3 CSD 1, or higher, can run on the same machine
as WebSphere Application Server's embedded JMS provider; however, earlier
versions of WebSphere MQ cannot coexist with the embedded provider.
It is important that WebSphere MQ is installed before WebSphere is
installed when MQ and embedded messaging coexist. Also, only WebSphere MQ
5.3 CSD 1 or later versions are supported for use with WebSphere
Application Server version 5.0.
