Adding Security Elements to the Deployment Descriptor

To enable basic authentication for the service, add security elements to the application deployment descriptor, web.xml. The security elements that need to be added to the deployment descriptor include the <security-constraint> and <login-config>elements. These security elements are discussed in more detail in Declaring Security Requirements in a Deployment Descriptor and in the Java Servlet Specification. Code in bold is added to the original deployment descriptor to enable HTTP basic authentication. The resulting deployment descriptor is located in tut-install/javaeetutorial5/examples/jaxws/helloservice-basicauth/web/WEB-INF/web.xml.
