Generating an XML Schema

To generate an XML schema from a Java object model:

1. Create a class that extends javax.xml.bind.SchemaOutputResolver.

   private class MySchemaOutputResolver extends SchemaOutputResolver {
    
       public Result createOutput(String namespaceURI, String suggestedFileName) throws IOException {
           File file = new File(suggestedFileName);
           StreamResult result = new StreamResult(file);
           result.setSystemId(file.toURI().toURL().toString());
           return result;
       }
    
   }

2. Use an instance of this class with JAXBContext to capture the generated XML Schema.

   Class[] classes = new Class[4]; 
   classes[0] = org.example.customer_example.AddressType.class; 
   classes[1] = org.example.customer_example.ContactInfo.class; 
   classes[2] = org.example.customer_example.CustomerType.class; 
   classes[3] = org.example.customer_example.PhoneNumber.class; 
   JAXBContext jaxbContext = JAXBContext.newInstance(classes);
    
   SchemaOutputResolver sor = new MySchemaOutputResolver();
   jaxbContext.generateSchema(sor);
