Transport-level Asynchronous Support Example
Now let's use full asynchronous support in Axis2, which requires WS-Address support for both the client and server sides. You can engage the addressing module on the server side using any of the available ways for doing that, but in this example, you use the following source code to start Axis2 and engage addressing (in real life, however, you would not use the following code to start Axis2).
1 package org.sample;
2
3 import org.apache.axis2.engine.AxisServer;
4 import org.apache.axis2.context.ConfigurationContext;
5 import org.apache.axis2.context.ConfigurationContextFactory;
6 import org.apache.axis2.transport.http.SimpleHTTPServer;
7 import org.apache.axis2.description.AxisService;
8 import org.apache.axis2.description.Parameter;
9 import org.apache.axis2.description.java2wsdl.Java2WSDLConstants;
10
11 public class AddressingEnableServer {
12 public static void main(String[] args) throws Exception{
13 ConfigurationContext configurationContext =
ConfigurationContextFactory.createConfigurationContextFromFileSystem(null, null);
14 SimpleHTTPServer smt = new SimpleHTTPServer(configurationContext, 8080);
15 AxisService service1 =
AxisService.createService(EchoService.class.getName(),
configurationContext.getAxisConfiguration());
16 configurationContext.getAxisConfiguration().engageModule("addressing");
17 configurationContext.getAxisConfiguration().addService(service1);
18 smt.start();
19 }
20 }
21
Now let's run the code. You will be able to access the service from http://localhost:8080/axis2/services/EchoService.
As previously mentioned, you also need to engage addressing on the client side. You can do that as follows:
