When a Web service is invoked from a Rich UI application, a request for that Web service is sent to the EGL Rich UI Proxy. Before you can access the proxy, you must enter a valid user id and password into a browser-specific dialog, such as the following dialog for Mozilla Firefox V2.0. For this example, the user id and password that you use to log in to your operating system are also used to authenticate to the EGL Rich UI Proxy.
You can use EGL single sign-on to combine custom authentication to your application with JEE authentication to the EGL Rich UI Proxy and bypass this dialog.
