Générer un Deployment Descriptor à partir de vos Classes de Service

Cette page est disponible uniquement en anglais.

In a previous article, we saw how to create run-time interfaces based on the parsing of a deployment descriptor. Here, we will see how we can generate a deployment descriptor from a Service Interface and Implementation.

This utility takes

and produces a well-formed DeploymentDescriptor, GeneratedDD.xml

The source code for this utility is in


This utility uses introspection to find out the methods for which to generate mappings, and recursion to generate Type Mappings for all beans that are linked to the service implementation. Naturally, all primitive types and all "java.lang" types do not generate Type Mappings.

The extracted info from the classes will map to the following template fields in the deployment descriptor template:

  • %serviceName%
  • %spaceDelimitedMethodNameList%
  • %fullyQualifiedImplementationClassName%

The info found for each bean will map to the following template fields in the mapping entry template:

  • %serviceName%
  • %fullyQualifiedBeanClassName%

The code simply replaces the template fields above with their real values. Care is taken not to generate the same bean mapping twice.


When you already have a set of services to export as SOAP services, you can use this utility to quickly generate a standard deployment descriptor for your services. Again, this reduces mistakes due to the strong coupling that exists between the Java code and the deployment descriptor.
