Question

I have a web service with several methods, each method has its own response and request (POJO classes).

I want to distribute XSD files to my users, so I have decided to use JAXB to generate the schema files.

My problem is that I want to have individual files (one per service)!!

I have tried JAXB but all I get is a big XSD with all my objects

When you publish your Web Sevice with JAX-WS, wsdl tells everything what each client’s needs and scopes.

Anyway.. say JAX-RS?

You can generate small scope of XSDs for each class or some classes with JAXBContext#generateSchema

public void generateSchema(final Class<?> classesToBeBound,
                           final OutputStream schemaStream)
    throws JAXBException, IOException {

    final JAXBContext context = JAXBContext.newInstance(classesToBeBound);

    context.generateSchema(new SchemaOutputResolver() {
        public Result createOutput(final String namespaceUri,
                                   final String suggestedFileName)
            throws IOException {

            return new StreamResult(schemaStream) {
                @Override
                public String getSystemId() {
                    return suggestedFileName;
                }
            }
        }
    });
}
