I have no idea what you trying to achieve with above code, but that is one hell of example on inappropriate use of JSP.
Putting servlet logic into JSP OUCHHHHHHH

all i want to know is if the code functions or not, ie displays the error message.
and forget the servlet, its just there for the sake of being there

it is supposed to process the parameters entered in a previous page, and validate them, if they are incorrect it sends an error message. a web developer and a friend of mine told me it looks sound as a JSP but he cant debug, which is what i need, if the parameters are correct it opens 2 mailto links

Just do not tell me this is a school project and your teacher specifically told you to only use JSP and not servlets. Seriously I'm on the edge to explode on all these silly teachers demands that I seen in recent days in JSP section.
Reason is simple page1 send validation to servlet. Servlet does the validation and decide if to return back to page 1 or or go forward to page2 as validation was correct.

its university and well i just wanna make sure the syntax is correct, and i know its stupid but ill repeat the year without this

Member Avatar for peter_budo

Then do it in correct way. Split the above code on servlet(the validation section) and JSP page (the html bit). Do you actually have installed Tomcat server with appropriate libraries?
