This error message is about a badly formatted JSP page at line 13,
column 51 (or is it line 51, column 13 - I never can remember). Apparently
Jasper doesn't like your variable firstname. Without seeing your code its
difficult to guess the cause of this, but its probably because you haven't
declared you want to use a bean using jsp:useBean before you have called
jsp:setProperty. Again, this is just a guess from the exception you
included.
This is in no way a runtime error, but a parse and compile time
error, therefore it is impossible to infer whether or not Tomcat is
correctly handling request.getParameter(), however from my own experience,
it follows the servlet spec.

Subject: A JSP/Jasper question
The servlet spec defines that request.getParameter() returns null if the
parameter wasn't passed to the page. However, it would appear that Jasper
chokes on this case. Since JSPs are an extension to servlets shouldn't the
behavior be the same? If I hacked the URL to pass in all the parameters for
the page when the page is compiled, will I get this error with future
acceses when, theoretically, Jasper isn't involved anymore?
