Ok i need some help with this JSP page that has some java in it. My assignment is to create a fictional webpage that requires a login or registration and that checks with the database to make sure that it will verify that no user with the proposed user id presently exist.

When i try to compile this program i get the following error:

HTTP Status 500 -

They could flap their wings 12-90 times per second  (depending on the species). Their English name derives from the characteristic  hum made by their rapid wing beats.<br></td>

		or perching. Hummingbirds feed in many small meals, consuming many small

Hummingbird flight has been studied intensively from an aerodynamic perspective 
using wind tunnels and high-speed video cameras. Writing in <i>Nature</i>, the
biomechanist Douglas Warrick and coworkers studied the Rufous Hummingbird, <i>Selasphorus rufus</i>, 
in a wind tunnel using particle image velocimetry techniques and investigated 
the lift generated on the bird's upstroke and downstroke. They concluded that 
their subjects produced 75% of their weight support during the down-stroke and 
25% during the up-stroke. <br> <br>Many earlier studies had assumed (implicitly 
or explicitly) that lift was generated equally during the two phases of the 
wingbeat cycle, as is the case of insects of a similar size. This finding shows 
that hummingbirds' hovering is similar to, but distinct from, that of hovering 
insects such as the hawk moths.The Giant Hummingbird's wings beat at 8-10 beats 
per second, the wings of medium-sized hummingbirds beat about 20-25 beats per 
second and the smallest can reach 100 beats per second during courtship 
displays.</td>

Break all those scriptlets out into a Bean or three. Do not use scriptlets in a JSP any more than absolutely necessary (which they never really are). They are nothing but a maintenance nightmare (as you are now experiencing).
