...
pushPage.context.setDomain("foo.com");
...
lsEngine.context.setDebugAlertsOnClientError(true) ;
lsEngine.connection.setLSHost("xxx.foo.com");
lsEngine.connection.setLSPort(8080);
lsEngine.connection.setUserName("user");
lsEngine.connection.setPassword("password");
lsEngine.connection.setAdapterName("MobileStreamin g");
lsEngine.changeStatus("STREAMING");
...
