There is nothing like this in the standard servlet API. However, you could build a
utility method that did this for you. It could accept a JavaBean instance and your
current HttpServletRequest as arguments, use the Java Reflection API to introspect
the property names supported by that bean, and do the appropriate assignments based
on the parameters included in the request.
Because this process is so similar to what a JSP engine does for the servlet
generated by your JSP pages, it might be possible to look at the source code for an
existing JSP engine implementation (such as Jakarta's Tomcat at
<http://jakarta.apache.org>), extract the code that does this for that
implementation, and use it as a starting point for your utility class.
