Define the middle tier for the Road Sign Review application.
a) Opening roadSigns.jsp. Open the roadSigns.jsp that you modified b) Displaying road sign images. In the roadSigns.jsp source code, add a while statement to roadSigns.jsp. The loop should obtain the image file name and image name from each row in the ResultSet and use them to insert an img element in the page. Note that the loop replaces the long list of image elements that you added to this JSP . The remaining img element will appear as literal HTML markup between the two scriptlets that start and end the while statement. Two JSP expressions should be used to obtain the image file name and image name from the ResultSet. c) Closing the ResultSet. In the second scriptlet and after the while statement, add code to close the ResultSet invoking its close method. d) Defining the form’s method and action attributes in the states.jsp page. In the roadSigns.jsp source code, specify "post" as the form element’s method and use the action attribute to forward the client request to roadTestRegistered.jsp. e) Saving the file. Save your modified source code file. f) Opening roadTestRegistered.jsp. Open the roadTestRegistered.jsp file that you created in Exercise 1.13. g) Displaying the client’s name. In the roadTestRegistered.jsp source code, modify the paragraph element that contains “confirmation” to use a JSP expression to obtain the client’s name from the JSP implicit object request and display it in the paragraph. h) Displaying the client’s phone number. Modify the paragraph element from the previ- ous step to use a JSP expression to obtain the client’s phone number from the JSP implicit object request and display it in the paragraph. i) Saving the file. Save your modified source code file. j) Copying roadSigns.jsp and roadTestRegistered.jsp to the RoadSign directory.
