Best way to execute different jspx pages from a parameterized URL

Question

JDeveloper 10.1.3.3.0
I'm looking for an elegant way for ADF to determine which page to go, based on a parameterized URL.
I currently have a way of doing it, it's not what I want, but perhaps some other ideas.
For example:
http://localhost/MyDemo-ViewController-context-root/faces/decisionPage.jspx?vehicleType=car
http://localhost/MyDemo-ViewController-context-root/faces/decisionPage.jspx?vehicleType=boat
Given vehicleType, I need decisionPage.jspx to go to car.jspx or boat.jspx immediately
Currently, I had to do this:
1. Expose a method in the application module setVehicleType()
2. decisionPage.jspx has a binding for a methodAction to call setVehicleType() and grab the vehicle type using ${param.vehicleType}. Store the vehicle type in the application module when this page is loaded.
3. In decisionPage.jspx, create a commandButton into the page
4. When the user clicks on this commandButton, it will be bound to a UI bean.
5. This UI bean will then get the vehicleType from the application module method getVehicleType()
I don't want the client to go directly to car.jspx or boat.jspx. I also don't want this extra step of the client clicking on a button to go to the proper page.
Any suggestions would be great!

Hi user,
You could create a jsp page (or a servlet) which acts as the starting point of your web application. (decisionPage.jspx in your case). In the jsp, grab the url parameters using a scriptlet, put them on the sessionScope and redirect to the correct page.
By putting the value on sessionScope, you have access to the parameters in your whole application during the session. You can use it to execute a query with bind variables.
Hope I made it a bit clear.
