no .do's in the form action calls in the jsp's

I don't understand what I am doing wrong.  It appears that most if not all of the form actions do not have their .do's appended on the end which means I get a 404 when I hit the submit button on login or register.  Of course I could modify the JSP's by adding the .do and they would work but I have a feeling that there is some config piece I'm not doing right?


Here is a snipet of jsp for register

<html:form action="/register" focus="username">

Why isn't it

<html:form action="/register.do" focus="username">
because that works.

Any suggestion would be appreciated.

Thanks
