Hi.

pid's right - you should really put your classes in packages (although I'm
pretty sure it's not technically mandatory). But looking at your attached
files, I think I see another problem - confusion between the Java class
package and the servlet mapping.

In the web.xml <servlet> element, you reference a Java class and give it a
servlet name. Looking at your web.xml, I see a ukjava1900 servlet with the
class com.multitel.ukjava1900. This means that you must have a
myApp\WEB-INF\classes\com\multitel\ukjava1900.class in your webapp. All good
till now.

The web.xml <servlet-mapping> element maps a servlet name (defined above) to
actual URLs that will be used to access that webapp. This URL has nothing to
do with the Java class. In your web.xml, I see
<url-pattern>/com/multitel/ukjava1900</url-pattern>
- this is wrong (unless you want users to access
/servlet/com/multitel/ukjava1900). Change this to
<url-pattern>/ukjava1900</url-pattern> and it should work.

Try to understand the difference between your Java classes, their packages
and the directory hierarchy under WEB-INF\classes on the one hand, and the
URL namespace of your webapp on the other.
