WebSphere Transformation Extender
WebSphere Transformation Extender (WebSphere TX) is a separately licensed product and is not included as part of WebSphere ESB. Using WebSphere TX, you can create maps that can transform data between a wide variety of formats.
WebSphere TX for Integration Servers adds and enables the following components for use in your message flows:
- A mediation primitive for running WebSphere TX maps, called the WTX Map primitive
- A data format transformation for running WebSphere TX maps called the WTX Data Format Transformation
For more information on using WebSphere TX, see 
http://publib.boulder.ibm.com/infocenter/wtxdoc/v8r3m0/index.jsp.
There are some circumstances in which it is not possible to transform the message to your required structure using the BO Mapper, Mapping and Data Handler mediation primitives. In these cases WebSphere TX maps can be used to transform the data. WebSphere TX maps can be called using the WTX Map mediation primitive or by using the WTX Data Format Transformation in a Data Handler mediation primitive or in an Import or Export.
You can use the WebSphere TX maps and type trees in the following ways:
- Pulling data from sources such as files and queues within a map
- Calling external programs and services from a map
- Splitting and routing batches of messages
Use WebSphere TX type trees if you need message modeling features that are not available with native data format transformations, such as:
- Modelling complex binary or text message formats that Business Objects are unable to model
- Complex validation without having to write code, using component rules on type trees
- Use WebSphere Transformation Extender Industry Packs to integrate a range of industry standard data formats with your enterprise infrastructure through predefined type tree templates and maps that the packs provide.
