Ugh..... sorry for all the trouble guys. Yeah, that was it. I guess I
saw the equals sign from the <%=...%> and just associated it with the
INPUT tag. It is still weird that an INPUT tag where the value part was
value"" without an equals sign would generate a value of " " and not a
null within tomcat. I'm not sure if it is the browser or tomcat created
the space.
Thanks for the help...
