/**
 * This class is the application being tested and also the client which
 * is used to test if the given version is enabled. This is because an appclient/jws
 * application is executed on the client side.
 *
 * We have to setup a system to retrieve the client-stubs of the currently enabled
 * version. This is because "asadmin get-client-stubs" always returns the client-stubs
 * regardless the given version is enabled or not. On the other side lauching
 * the appclient from the stubs either by hand or with appclient script will succeed
 * regardless the version enabled.
 *
 * Using this appclient after a deployment (without enabled=false) or an
 * activation process (enable) will always succeed with testPositive=true
 * (expectedVersionIdentifier will always be equals to retrievedVersionIdentifier).
 *
 * Moreover using this appclient after a deactivation process will always fail
 * with testPositive=false.
 *
 * As a conclusion we can say that this test isn't consistant if launched from a
 * client-stub retrieved with the "asadmin get-client-stubs" command. Instead,
 * we choose to use the Java Web Start URL ([host:port/contextRoot], the
 * contextroot equals to the untagged if not provided in the deployment descriptor)
 *
 * The stubs are retrieved with JWS mechanism, it allows us to change the enabled status
 * and make some tests.
