When you define setCategoryNo and/or getCategoryNo, the property name is
"categoryNo" (first letter lowercase !), like a normal member variable would
be called if you follow the java coding conventions.

The parameters you pass to your jsp-page need to be in the proper case as
well, that's why the <jsp:setProperty name="category" property="*" /> didn't
work either...
