One of the requirements of a JavaBean is that it have a no-args constructor.
You can use <jsp:setProperty> to set property values in the bean.

Better... instantiate and configure the bean in Servlet code, place it in
the appropriate scope and forward to a JSP that just uses the
already-existing bean.

Otherwise, you'll have to resort to a scriptlet to instantiate the bean.
