WebSphere Transformation Extender data binding descriptor

The WebSphere® Transformation Extender data binding descriptor is a URI that describes the incoming message.

Purpose

The WebSphere Transformation Extender data binding descriptor is set by the client in the headers of the incoming message. It provides the information required to associate the incoming message with the correct map in the WebSphere Transformation Extender.

Using the WebSphere Transformation Extender data binding descriptor is one of two ways that you can set the invocation of the map. The alternative is to configure the properties of the WebSphere Transformation Extender data handler in WebSphere Integration Developer. However, you should use the WebSphere Transformation Extender data binding descriptor when you want to use a different map for each invocation of the operation.

For example, consider an export with an operation Create(Customer). If you want every invocation of this operation to use the same WebSphere Transformation Extender map for each customer, then configuring the properties of the WebSphere Transformation Extender data handler in WebSphere Integration Developer is an appropriate choice.

However, you might want to invoke a different map depending on the customer. In this case the operation is invoked with customer and uses a different map for every invocation. Such a scenario cannot be configured in the properties of the data binding and you must instead use the data binding descriptor.

Syntax

The WebSphere Transformation Extender data binding descriptor has the following syntax
databinding://domain/property?queryParameters
domain is WTX for this data binding.
property has the value map in this case.
queryParameters is either name=mapname where mapname is the name of the map required, or businessObject=Customer&contentType=format, where Customer is the name of the Business Object and format is the format of the data stream (for example, COBOL, EDI, and so on).

Sample

Examples of a WebSphere Transformation Extender data binding descriptor are shown below:
databinding://WTX/map?name=WTX/CustomerToCOBOL
Note: A directory called WTX must be in the top level of the module and must contain any maps that are required by this binding.
databinding://WTX/map?businessObject=Customer&contentType=COBOL
databinding://WTX/map?contentType=COBOL
