List of students and ports this semester.

Fri May 01

Link to individual appointments script.

Final exam date: for our starting time (12:20 and 1:20 p.m. Tu,Th,Sa) the final is at 7:15-9:15 p.m., Thurs., May 7

Database queries for Homework Three: here.

The code we developed in class today.

Here are three files implementing a nice idea by Mason:

one.php called first
initializes session and sends data to main.php
which in turn redirects us to two.php
passing along the data; the session variables are available in it too

Idea is good, looks like Homework Five.

Note that main collects all the finalize of all the screens.

Tue Apr 28

Here's some code we will look at today.

Notes from class today.

Thu Apr 23

Today in class we will introduce ASP.NET 3.5 with C# using Visual Studio 2008.

Things to use as reference during this process: Overview, Getting Started.

We will also connect some various other loose ends (from last time, from lab last week etc.)

Tue Apr 21

In class notes will be available in real time here.

Thu Apr 16

Code developed in class today: servlet, JSP.

Tue Apr 14

Notes from today's class.

Sat-Sun Apr 11-12

Notes developed in class on Fri.

The second servlet developed on Fri from 12:20-2:15pm.

Fri Apr 10

Lab today: servlets, a servlet-applet web chat application, servlets vs. JSP.

Review pages 135-152 from the Essentials (chapters 17 and 18).

Highlights of what's relevant for the lab this week:

make sure your Tomcat is installed
create a new context and make it reloadable
add a servlet to the classes folder
add a description in the associated web.xml for the servlet
compile and access the servlet, change and recompile the servlet until done

A JSP that implements the Flag Quiz.

The notes with sample Java web server developed from scratch are here (also listed on the lab assignment page).

Notes to serve as a reference and guide when discussing servlets and JSP: one, two, three.

These are the files needed for the web chat application:

     chat/HttpMessage.class
     chat/ChatApplet.class
     chat/HttpMessage.java
     chat/WEB-INF/lib
     chat/WEB-INF/classes/MessageSource.class
     chat/WEB-INF/classes/MessageSink.class
     chat/WEB-INF/classes/Chat.java

     chat/WEB-INF/classes/ChatServlet.class
     chat/WEB-INF/classes/Chat.class
     chat/WEB-INF/classes/ChatServlet.java
     chat/WEB-INF/classes
     chat/WEB-INF/web.xml
     chat/WEB-INF
     chat/index.html
     chat/ChatApplet.java
     chat

Note that echo $JAVA_HOME and which javac/java should return consistent outputs/values.

A common mistake would be to use jdk1.5 for JAVA_HOME and jdk1.6 for javac/java. (You get bad version number in class then...)

Thu Apr 09

Brief notes from today's class.

Tue Apr 07

Here are some notes from today's class.

Fri Apr 03

Set the environment variables if you use tcsh as follows:

setenv JAVA_HOME   /l/jdk1.5
setenv CATALINA_HOME /u/dgerman/apache-tomcat-5.5.17
setenv CLASSPATH   .:$CATALINA_HOME/common/lib/servlet-api.jar

Make these changes in ~/.cshrc (for tcsh).

Use the notes for other shells.

Thu Apr 02

What we discussed on Tue and some slides for today.

Fri Mar 27

Thu Mar 26

Programs discussed in class today:

<html>
  <head><title>Program in Javascript</title></head>
  <body>
    <script language="Javascript"> 
 
      var counter = 0; 

      function up() {
        counter += 1; 
        document.getElementById("joe").innerHTML = counter; 
      } 

      function down() {
        counter -= 1; 
        document.getElementById("joe").innerHTML = counter;
      } 

    </script> 
    <table>

      <tr> <td colspan=2 align=center> <h1><span id=joe>0</span></h1> 

      <tr> <td> <input type=button value=Down onclick=down()> 
           <td> <input type=button value=Up   onclick=up()>
    </table> 
  </body> 
</html>

The program is the second we wrote, uses buttons. The one below is the same from Tue.

<html>
  <head><title>Program in Javascript</title></head>
  <body>
    <script language="Javascript"> 
 
      var counter = 0; 

      function up() {
        counter += 1; 
        document.getElementById("joe").innerHTML = counter; 
      } 

      function down() {
        counter -= 1; 
        document.getElementById("joe").innerHTML = counter;
      } 

    </script> 
    <table>

      <tr> <td colspan=2 align=center> <h1><span id=joe>0</span></h1> 

      <tr> <td> <a href=javascript:down()>Down</a> 
           <td> <a href=javascript:up()>Up</a>
    </table> 
  </body> 
</html>

The only difference is that now we can access and update HTML elements on the page.

    }     
    function goDown() {
      counter -= 1; 
      alert("The counter is now: " + counter);
    }
