• Create a screen with three clickable buttons equally spaced horizontally. If you can put them at the bottom of the screen, it would be great. But the vertical location is not critical for now.

  Click on the left button will lead to another HTML page, e.g., CSCI 479 Home Page, click on the other two buttons will lead a message of your choice, e.g., Job well done!

  Here is a sample page that resembles the look.

• Create a program that can read a local file, print the file name on the screen. (I'd recommend working on the survey paper first.)

  Here are some pointers that may help.

  • HTML5:

• Practice with mysql database. This description is based on Java and JDBC, other programming languages follow similar patter.
  • Edit your .cshrc file, add the following line to the file in a proper place. The save the file.

    # for mysql 10/01/2012
    setenv CLASSPATH /usr/share/java/mysql-connector-java.jar:${CLASSPATH}:.
    

  • At the command line, type

    source .cshrc
    

    for the path to take effect.
  • For bash users, edit the .bashrc file

    export CLASSPATH=/usr/share/java/mysql-connector-java.jar:${CLASSPATH}:.
    

  • At the command line, type

    source .bashrc
    

    for the path to take effect.
  • Copy the Java example program PQQuery.java to your own directory.
  • Go to the program and revise the part where my name (meng) appears and change it to your user name and DB name of your choice.
  • Compile the program using the command

    javac PQQuery.java
    java PQQuery
    

  • Type in the user name and the password. (If you don't like to see the user name and password in plain text, you can create an input file that contains your user name and password in one line, sperated by a space, e.g. "user pass".) and run the program in this fashion.

    java PQQuery < userinfo
