Use this task to develop your own extensions for the gateway.
Before you begin
The filters that you create as described in this topic and sub-topics use the gateway WorkArea to maintain context. The gateway WorkArea is only available with IBM WebSphere Application Server Enterprise Version 5 or WebSphere Business Integration Server Foundation Version 5.1. Therefore you can only deploy these filters on WebSphere Application Server Enterprise Version 5 or WebSphere Business Integration Server Foundation Version 5.1.
