CGS4825, Assignment 6

Due Friday 12/5 at midnight

You are to create a project that has one servlet and several JSPs. Create a JAR file and upload it.

Use POST when submitting the data from the browser to the server.

Add a link to your server's default page that links to this servlet.

• You should place .class files in your classes directory for your web app on Otter and run them from the path
  /cgs4825_your-user-name/servlet/MyServlet
• You should be able to place .jsp files in the java-servlets directory and run them from the path
  /cgs4825_your-user-name/MyJSP.jsp
• In general, you should give directories 705 permissions and files 604 permissions. There is one exception: the directory where you will be storing your database file. In order to create the database the first time, the directory will need 707 permissions. After you run your servlet once, you can go back and change the permissions to 705. 707 is a very dangerous permission!
• The path name that you use in Java to construct the simple database must be the full path name: /aul/homes/........
• You can use a .jar file to upload your work from your PC to otter. I suggest you just unpack it on the server with
jar -xvf file.jar.

There will be several different JSP pages displayed by this project.

• The Login Page.
• The Form Page. If this page is loaded in repsonse to the submit button from the Login Page and the Phone Number is in the database, then fill in the form elements with the data from the database. If this page is loaded in response to any other form button, then be sure that the form elements are filled in with the previous values (make it sticky).
• The Confirmation page. This page displays all the information that the user has submitted, but as plain text, not in HTML form elements. Arrange the data in a nice HTML table.
• Each page should include a header and a footer. These files should be in the /cgs4825_your-user-name/includes directory of your server. The header should contain some information about the servlet that you are creating. The footer should contain some information about your website. Each page will display the same header and footer. Remember that when you use the <jsp:include> directive, paths that start with a / are relative to the web app root, not the document root.
• Use the same style sheet to control the look of each page. Use an HTML <Link> tag to control this. Remember that this is a HTML statment, so that paths start with a / are relative to the document  root.
<LINK REL="STYLESHEET" TYPE="text/css" HREF="location-of-style-sheet">

The Login Page will display a form with a Submit button and a text box for the Phone Number, and a text box for an E-mail Address.

• The Phone Number should be "sticky".
• The Phone Number cannot be blank.
• Validate that the Phone Number is in one of these formats:
  999-999-9999; 999 999 9999; 999.999.9999; 999999999.
• You might find these links helpful for checking that the phone number is in one of these formats

  • http://java.sun.com/j2se/1.4.1/docs/api/java/util/regex/Matcher.html
• If the Phone Number is invalid, then redisplay the Login Page with an appropriate error messages.
• If the Phone Number is valid, then initialize the Form Page as follows
  • If the Phone Number is already in the database, then fill in the Form Page with the user's data from the database. Note: the database is read only when the Form Page is called in response to the button on the Login Page.
  • If the Phone Number is not in the database, then all the form elements in the Form Page should be empty.

The Form Page will have the following.

• The form should be sticky.
• Display the Phone Number on the page as plain text (do not display it in a form element). Display it in the format (999) 999-9999, regardless of how the user entered it.
• The form will contain the following elements. Arrange them in an HTML table: place the text describing the element and the element itself in separate <TD> tags.
  • A text box.
  • A radio group with at least four options.
  • A multiple selection drop down list with at least five options.
  • Add some text that identifies each element.
• A Submit button. When this information is submitted, the script should verify that
  • The text box contains at least two words.
  • The radio group has been selected.
  • Between 2 and 4 selections have been chosen from the selection list.
  • If there are invalid fields, then redisplay the Form Page with all appropriate error messages. If there are multiple errors, then display all the errors. Change the background color of each <TD> element that contains an invalid field. Use your stylesheet to control the color. Be sure that the form is sticky.
  • If all the fields are valid, then display the Confirmation Page.

The Confirmation Page will have the following:

• Display the user's information as plain text (do not display them in form elements.)
• Display the following buttons in a form:
  • Edit: if clicked, then the Form Page is redisplayed, with all of the user's information filled into the form. Use the information from the Confirmation Page, not the information in the database. The Phone Number should still be displayed as plain text in the Form Page.
  • Confirm: if clicked, then write the user's information to a database. Do not write to the database until this button is clicked. Use the Phone Number as the key field. Redisplay the Confirmation Page with with an extra message indicating that the data has been entered into the database.
  • New User: if clicked, then display an empty Login Page.

Please note that the data is not entered into the database until the user presses Confirm on the Confirmation Page.

I have created a simple database for you to use: SimpleDB.java
