One common practice to version web services is using XML namespaces to clearly delineate the versions of a document that are compatible. For example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<wsdl:types> <schema targetNamespace="http://apache.org/2007/03/21/hello_world_xml_http/mixed/types" xmlns="http://www.w3.org/2001/XMLSchema"> <element name="sayHi"> <complexType /> </element> .......... </schema> </wsdl:types> |
Among many different possible implementations of service routing, one simple way ("simple" in terms of amount of code you have to write, but it does require a certain extent of familiarity with CXF internal architecture) to do this is by writing a CXF interceptor that acts as a routing mediator.

import javax.xml.ws.Endpoint;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.testutil.common.AbstractBusTestServerBase;
import org.apache.hello_world_mixedstyle.GreeterImplMixedStyle;
public class Server extends AbstractBusTestServerBase {
protected void run() {
//implementor1 and implementor2 are published using local transport
Object implementor1 = new GreeterImplMixedStyle();
String address1 = "local://SoapContext/version1/SoapPort";
Endpoint.publish(address1, implementor1);
Object implementor2 = new GreeterImplMixedStyle();
String address2 = "local://SoapContext/version2/SoapPort";
Endpoint.publish(address2, implementor2);
//A dummy service that acts as a routing mediator
Object implementor = new GreeterImplMixedStyle();
String address = "http://localhost:9027/SoapContext/SoapPort";
javax.xml.ws.Endpoint jaxwsEndpoint = Endpoint.publish(address, implementor);
//Register a MediatorInInterceptor on this dummy service
EndpointImpl jaxwsEndpointImpl = (EndpointImpl)jaxwsEndpoint;
org.apache.cxf.endpoint.Server server = jaxwsEndpointImpl.getServer();
org.apache.cxf.endpoint.Endpoint endpoint = server.getEndpoint();

}
public static void main(String[] args) {

s.startrun();
} catch (Exception ex) {
ex.printStackTrace();
System.exit(-1);
} finally {
System.out.println("done!");
