You have built a web application that you license to small businesses. The webapp uses a context
parameter， called licenseExtension， which enables certain advanced features based on your client’s licensepackage. When a client pays for a specific service， you provide them with a license extension key that theyinsert into the  of the deployment descriptor. Not every client will have this contextparameter so you need to create a context listener to set up a default value in the licenseExtensionparameter.

You have a simple web application that has a single Front Controller servlet that dispatches to JSPs togenerate a variety of views. Several of these views require further database processing to retrieve the necessary order object using the orderID request parameter. To do this additional processing， you pass therequest first to a servlet that is mapped to the URL pattern /WEB INF/retreiveOrder.do in the deploymentdescriptor. This servlet takes two request parameters， the orderID and the jspURL. It handles the databasecalls to retrieve and build the complex order objects and then it dispatches to the jspURL.
