In this lesson, we run the secure version of the Openwings HelloWorld
demo. In the original
demonstration, the HelloWorldProvider component provides the
com.gd.openwings.demo.helloworld.synchronous.HelloWorldServiceSync
service using a basic Java RMI connector. The HelloWorldUser component
uses the service provided by the HelloWorldProvider and makes
calls on the service, displaying the results in a window.
In this version of the demonstration, the same HelloWorldUser
component is reused, but we introduce a new provider called "HelloWorldProviderSecure".
This demo component is also configured to provide the HelloWorldServiceSync
service, but it does so using a secure RMI GSS connector.
Follow the steps outlined in the Getting
Started tutorial. That trail describes how to install the
components for the synchronous HelloWorld demonstration, including
HelloWorldServiceSync and HelloWorldUser. The only difference
is that you should install and run the HelloWorldProviderSecure
component instead of the HelloWorldProvider component.
When you run the demonstration, you should see no difference
(assuming you've already started the Openwings core, you won’t
even see a login screen). This is by design; the use of secure
connectors is meant to be as transparent as possible.
Also note that there are basically no differences in source code
between the HelloWorldProvider and HelloWorldProviderSecure components,
with the exception of package names. The HelloWorldProviderSecure
component is simply configured to use a secure connector. The
HelloWorldUser component required no changes at all, it transparently
uses any service that implements the HelloWorldServiceSync interface.
In the next lesson, we begin to explore how the HelloWorldProviderSecure
component was built, starting with generating a secure connector.
