Hi Ted, what if I wrote a HOW-TO on creating Struts/JSP web components? Not standalone ones that can be created with Struts Dialogs, but real page fragments, that are created using bare JSP, five or so tags and any action framework like Struts or WebWork?
I started up a new project on SourceForge, called JSP Controls. This is basically a further improvement on ideas of Struts Dialogs. The deficiencies of current servlet spec forced me to handle input and output on a JSP page, basically creating a sort of view helper thing. The best feature is that a component is fully independent of page it is contained in, and can work both in in-place update mode (Ajax mode or, some may say, AHAH mode, whatever) as well as in standard synchronous mode using good old redirection. I started moving some stuff from Struts Dialogs to JSP Controls, and a new project is simpler and more powerful. I think demo while not looking terribly mindblowing, shows the features: http://www.superinterface.com/jspcontrols/index.html This is how the source code for login component looks like: === cut here === <%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib uri="/WEB-INF/lib/jspcontrols.tld" prefix="jc" %> <span id="LoginComponent"> <%-- Accept phase --%> <jc:accept> <jc:handler event="login"> <jsp:include page="/login.do" /> </jc:handler> <jc:handler event="logout"> <jsp:include page="/logout.do" /> </jc:handler> <jc:reload/> </jc:accept> <%-- Render phase --%> <jc:prerender> ... </jc:prerender> <jc:render view="notloggedin"> ... </jc:render> <jc:render view="loggedin"> ... </jc:render> </span> === cut here === The sample above uses simple Actions, but dispatching action also can be used. The Mini Blogger uses Ajax mode if possible for Comment Component, when you click on "Add Comment" or "Cancel". If you submit a comment, it uses full page reload, but composite page knows nothing about what happened. Login Component uses page reload because I needed to update Admin Component *after* I changed the user status, so doing this in Ajax mode did not ensure proper sequencing. I am working on that. The login/password for admin mode is "user"/"password" like in MailReader. I am going to rewrite MailReader using this page fragment technology, should look really cool. Michael.
