About this task
The channel component is restructured in
IBM® WebSphere® Multichannel Bank
Transformation Toolkit version
8.0. Besides
ChannelRequest and
ChannelResponse,
which help to achieve protocol and channel independency, there are
some other changes in structure and code, including:
- In WebSphere Multichannel
Bank Transformation Toolkit version 5.2, CSReqServlet implements ChannelDriver.
In BTT version 8.0, CSReqServlet is
only a servlet and does not implement the ChannelDriver interface.
- In WebSphere Multichannel
Bank Transformation Toolkit version 7.0,
the BTTChannelDriver class was introduced, which
implements the ChannelDriver interface. In WebSphere Multichannel
Bank Transformation Toolkit version 8.0, the BTTChannelDriver class
is still used to implement the ChannelDriver interface.
- Because BTTChannelDriver implements ChannelDriver in WebSphere Multichannel
Bank Transformation Toolkit version 8.0, some
functions and methods in CSReqServlet are not in ChannelDriver.
To migrate the customer extended channel request handler and
response handler, you only need to refactor your application to the WebSphere Multichannel
Bank Transformation Toolkit version 8.0 channel
interface and move some methods and logic to the classes in WebSphere Multichannel
Bank Transformation Toolkit version 8.0.
