You dont mention anything about where the username/role comes from or is stored.
So I assume you are approaching this in a the wrong for a spring MVC app.
Perhaps you have come from php or something, where you just put your code in the php file and display the value in html, also in the same file.
In MVC, there is a completely different way of approaching things.
First you should consider your model/domain. This would be a User object and a Role object in your case.
Then you would build controllers to manage these objects. Then you would look at views (jsp) to present these objects to the end user. So in your case, jsp is the last thing to consider.
I recommend using spring ROO to build your simple app. It will generate/scaffold a spring MVC app based on your model/domain classes. It also uses all the spring best practices, so is a good way to learn how it all works.
