Table 14 2. Struts Faces tags (continued)

Tag name

Description

html

Generates an

 element with optional locale sensitivity, similar to the Struts

html:html

 tag

javascript

html:

javascript

 tag

loadMessages

Loads messages resources into a map for access by JSF tags such as

h:outputText

message

Displays a localized message, similar to the

bean:message

 tag

stylesheet

Generates a link to a stylesheet

write

Renders a property value from a model object, similar to the

bean:write

 tag

The

FacesRequestProcessor

processes the submitted logon form and executes the

LogonAction

. This action doesn't have to do anything special related to JSF. The

Struts Faces library integrates Struts and JSF so your action classes and action forms

require no modification when using JSF. Example 14 24 shows the

LogonAction

for

this application. A  real  action would authenticate the user.

Example 14 24. Action for logon

package com.oreilly.strutsckbk.ch14;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.commons.beanutils.PropertyUtils;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

public class LogonAction extends Action {

    public ActionForward execute(ActionMapping mapping, ActionForm form,

            HttpServletRequest request, HttpServletResponse response)

            throws Exception {

        String name = (String) PropertyUtils.getSimpleProperty(form, "username");

        User user = new User( );

        user.setUsername(name);

        request.getSession( ).setAttribute("user", user);

        return mapping.findForward("success");

    }

}

The application culminates by rendering a  welcome  page that includes text from

the message resources bundle as well as the username entered on the preceding form.

The welcome.jsp page, accessed through the welcome.faces path, is shown in

Example 14 25.

Example 14 25. Rendering HTML with JSF and Struts Faces tags
