Java APIs

I am trying to run the "Simple Example Doclet" at http://java.sun.com/j2se/1.3/docs/tooldocs/javadoc/overview.html.

It appears to compile ok, but when I go to run it I get the message "javadoc: Cannot find doclet class ListClass".

Listed below is:

1. The execution command and error message
2. The version (output of javadoc -J-version)
3. The javac compile command and input and output files

All directories have been kept the same as in the example.

Any help would be appreciated.

Thanks

1. C:\jdk1.3>javadoc -doclet ListClass -classpath C:\jdk1.3\lib\tools.jar MyClass.java
javadoc: Cannot find doclet class ListClass
1 error

2. javadoc -J-version
gives
java version "1.3.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode).

3. javac -classpath C:\jdk1.3\lib\tools.jar ListClass.java
appears to give good compile ....

e. g. Input source file ListClass.java is as follows:
import com.sun.javadoc.*;

public class ListClass {
public static boolean start(RootDoc root) {
ClassDoc[] classes = root.classes();
for (int i = 0; i < classes.length; ++i) {
System.out.println(classes);
}
return true;
}
}

and.....
decompiled ListClass.class file is as follows:
