Make sure that the following configuration is complete before trying to use an WebSphere MQ-bridge.
To use the WebSphere MQ-bridge you must have the WebSphere MQ Classes for Java (version 5.1 or greater) installed on your WebSphere MQ Everyplace system. WebSphere MQ Classes for Java is available for free download from the Web as supportpac MA88. The Web address for the download is: http://www.ibm.com/software/mqseries/txppacs/ma88.html. (The WebSphere MQ classes for Java for NT is shipped with WebSphere MQ Version 5.1 for NT.)
These classes must be added to the classpath set in the options file - see JVM options for details on how to specify the classpath.
