[fedora-java] HelloWorld Example Won't compile

I took the source for the HelloWorld example in the Tomcat5 samples
(http://your.server:8080/servlets-examples/helloworld.html), and tried
to compile it.

    [javac] Compiling 1 source file to /home/ccurley/src/com/charlescurley/hello/classes
    [javac] ----------
    [javac] 1. WARNING in /home/ccurley/src/com/charlescurley/hello/src/HelloWorld.java
    [javac]  (at line 5)
    [javac]     public class HelloWorld extends HttpServlet {
    [javac]                  ^^^^^^^^^^
    [javac] The serializable class HelloWorld does not declare a static final serialVersionUID field of type long
    [javac] ----------
    [javac] 1 problem (1 warning)

What am I missing here?

[ccurley at taltos src]$ echo $CLASSPATH
/usr/share/tomcat5/bin/:/usr/bin:/usr/share/java/servletapi5.jar:.
