Developing a Transformation Service

To map the content of an XML document from one XML schema to another, you must develop a transformation service. The result of this process is a transformation service file you can deploy to provide transformation functionality at runtime.

For additional information, see Transformation Services.

The following workflow guides you through the development process. For assistance in performing these tasks, open the Developing a Transformation Service cheat sheet.

Complete the setup.
1. Open the Service Development perspective.
2. Create a Sybase project in your workspace.
3. Import source and target content models to your project. Normally, content models are obtained by browsing an XSD or WSDL, but you can also use a Java service, EJB service, database service, or message definition created in Message Designer as long as the resources contain the right information.
Create the transformation service.
The transformation service editor opens.
Edit the service interface in the Service Interface page, if necessary.
1. Add an operation parameter.
2. Edit operation parameter properties.
Define the service implementation on the Map page.
1. Define links from source to target elements in the content models.
2. Add literals if necessary.
3. Add test conditions if neccesary.
4. Set up transformation rules using the Expression Editor.
Test the transformation performance using the Test tab.
1. Select an instance document for each source content model.
2. Verify the transformation functionality by reviewing the output documents.
Test the transformation service.
Test the transformation service by packaging and deploying it in a test environment. Testing the service assists in verifying its functionality prior to using the service in a composite service or publishing the service.
