<jsp:include> is effectively replaced by <c:import>; <jsp:useBean> and scripting variables are, with a few exceptions, superceded by JSTL's expression language; and <jsp:setProperty>'s function is handled using <c:set target="..." property="..." /> > 2.

You cannot; such functions need to be called by Java code, either in the page, in a Java-based component such as a servlet or a filter, or in a bean itself, wrapped by bean-style accessor methods. In JSP 2.0, you'll also be able to define expression-language functions in the TLD; this will let you access back-end methods as long as you've declared them accessible. -- Shawn Bayern "JSTL in Action" http://www.jstlbook.com -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
