WTX data handler concepts
Several WTX concepts should be known to you.
WTX data handler and IBM Integration Designer servers
The WTX data handler communicates with Websphere Transformation Extender over JNI since Websphere Transformation Extender is a C++ product. As a result, the WTX data handler runs in the same process space as Websphere IBM BPM or WebSphere Enterprise Service Bus.
WTX maps
The WebSphere Transformation Extender Data Binding invokes a WebSphere Transformation Extender map in order to perform the transformation. The map provides the system with the details of conversion from one format to another. The WTX data handler determines what map to call based on the configuration properties on the data binding or the data binding descriptor which is described in the runtime documentation. When converting native data like Electronic Data Interchange (EDI), for example, to data object, the map must be built with the input card from EDI and the output card based on XML Schema. When converting data object to native data, the map must be built with the input card based on XML Schema and output card based on native data.
