I am writing a simple JSP to calculate the distance between 2 points.  When I click on the "Submit" button, I get the following HTTP 404 error:

HTTP Status 404 - /distanceCalc/distanceCalculator.jsp%20method=

--------------------------------------------------------------------------------

type Status report

message /distanceCalc/distanceCalculator.jsp%20method=

description The requested resource (/distanceCalc/distanceCalculator.jsp%20method=) is not available.


--------------------------------------------------------------------------------

Apache Tomcat/6.0.16

What am I missing here?  Thank you in advance!
