Exercise 2 : Additional Lab Exercise

Note : This lab is not mandatory, it is there if you would like to take things further. There is little or no sample code although it is suggested that you use the code from the initial lab exercise as a starting point.

Passing data from the servlet to the JSP page

In the lab exercise we see how to call a JSP page from within a servlet. In an actual application we would pass the results of the servlet operation to the JSP page for display.

Read in a text file in the servlet and store the text file as a Vector of String objects. The text file to read should be hard coded into the servlet. Pass this Vector of Strings to the JSP page for display. The crucial element in this exercise is how to pass information from the servlet to the JSP page. I would suggest reading the Javadoc for the HttpRequest class.

Extensions

You could make the file which is read by the servlet dynamic by taking it as a parameter to the servlet.
