XML Schema files
can be used to define XML within the transformation process. WSDL files are used
to define the operations that are transformed within the service engine. We won't
discuss how WSDL files and XML Schema files are created and maintained in this
chapter, however, we will discuss them in full detail later in this book.
The final type of file that can be specified within an XSLT Module is an XSLT
Service. These types of files can be created by right-clicking on the XSLT Module
within the Project explorer in NetBeans and selecting the New | XSLT Service menu
option. The result is shown in the next screenshot.
When creating an XSLT Service Unit, two different processing modes (Service type)
are available:
Request-Reply Service
Service Bridge
??? ???
Service Engines
[ 46 ]
The Request-Reply Service mode enables an XML message to be received from a
client, transformed, and then sent back to the original client.
The Service Bridge mode enables an XML message to be received from a client and
transformed into a different format. The transformed message is then used as an
input for invoking a service. The output of this service is then transformed using a
second XSL stylesheet and returned to the original caller. The Service Bridge mode
is therefore acting as a bridge between two services.
