Flash Scope Lab for Tomcat 7
-----------------------------

- Create a Dynamic Web Project named flashWeb and 
  configure it for JSF.

- Create a domain class named Student that implements
  Serializable and provides properties for studentID,
  name and GPA.

- Create a managed bean class named StudentManager
  and annotate at request scope. This class should
  define a property of type Student and an action
  method named addStudent. 

  The addStudent method should store the student
  properties in the flash object and return a navigation
  string "displaystudent?faces-redirect=true".

- Create a JSF page named editstudent.xhtml with a 
  form that lets the user enter student info. The
  submit should invoke the addStudent() method.

- Create a JSF page named displaystudent.xhtml
  that displays the student info that was stored
  at flash scope

- Test and note that the URL changes after page
  submission (but refreshing the 'display' page
  doesn't work???)

Note that there are potential issues with Mojarra (we
are using a pretty old version in lab)
