Humm I can't see log() method in class GenericServlet nor field log see:
http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/GenericServlet.html

Clear, it's 2.2 API and you use 2.0 API.

[...thinking in progress...]

Arrg, Tom's solution may not work with servlet as System.setErr() and
System.setOut() call security manager as describe in
http://java.sun.com/products/jdk/1.2/docs/api/java/lang/System.html#setErr(java.io.PrintStream)

Let's try that class (not tested)

public class LogThruServlet extends PrintStream {
    private GenericServlet gs;

    public LogThruServlet (GenericServlet gs) {
        /* dummy initialisation of super classes */
        super (new OutputStream() {
               public void write(int b) throws IOException {
               /* Do nothing */
               });
        this.gs = gs;
    }

    public void print(String s) {
        gs.log(s);
    }
}

Then, in your servlet (may be in a constructor) add:
    
    PrintStream log = new LogThruServlet (this);
    System.setOut(log);
    System.setErr(log);

Hope this help.
