Hi Lance,
first, as already has been noted, Strings are checked for
equality by using equals(). Never saw something like
compareTo(); this performs a lexicographic comparison
and is to be considered bad style in this case.
Secondly, try adding a scriptlet end tag after the closing
brakes, like this: <% } <%>. You'll also have to add
another scriplet start tag before the 'else', of course.
May seem odd, but have a look at the final servlet
code. Note that this is dependant on the JSP engine
implementation; the only source of truth is the
servlet code that your specific implementation
finally produces.
HTH,

NB. Avoid naming something specific to your
application after something that has a fixed
meaning. Collection is an interface in java.util
with a fundamental role in the Collection
API (introduced in 1.2), and due to the Java
coding style guide, variables should always
start with a lowercase letter anyway :)
