MyFaces Tomahawk JSCookMenu - failure to navigate to page defined by action in faces-config

问答 作者：

This is my first attempt at using JSCookMenu and its homepage (http://jscook.yuanheng.org/JSCookMenu/) has been down for more than a week, so forgive me if the answer to my question should appear on there.

I have a simple web app, stripped down in order to test JSCookMenu's action forwarding to a new JSF page.

I have an admin page with a JSCookMenu (Apache MyFaces Tomahawk tags) with 2 menu items, 'Home Without AL' and 'Home With AL'. I expect that when I click on these menu items that I will navigate to the 'home' page which will just display a 'Hello World' message for now. This navigation is not happening, however. A push in the right direction would be greatly appreciated :-)

Here's my faces-config, my admin page (which uses layout page), my home page, my web.xml (with filter mapped) and a description of what happens when I click on the menu item.

faces-config.xml:

I have tomahawk12-1.1.9.jar in my classpath (also tried tomahawk-1.1.9.jar), which I downloaded from http://myfaces.apache.org/tomahawk/download.html.

I have a jscookmenu folder at the root of my webapp, containing a folder for each theme (each with theme.css and theme.js), effect.js and the JSCookMenu.js from jscookmenu-2.0.4.zip, all of which I downloaded from http://sourceforge.net/projects/jscook/files/. Latest release was 2009-05-25.

The web app is deployed on Sun GlassFish Enterprise Server v2.1 on localhost.

I browse to http://localhost:8080/beachwater/admin.jsp and click on the Home menu item.

New window is opened with address bar, "http://localhost:8080/beachwater/form_j_id7_menu:A%5Dgo_home" and content, "Glassfish error page, HTTP Status 404: The requested resource () is not available."

Nothing gets written to the server.log

The window is being opened by开发者_如何学运维 the cmItemMouseUp function in JSCookMenu.js. Do I have the wrong version of the javascript? Any ideas why the filter isn't invoking the action specified in faces-config?

It turns out that the 'Instructions' section on http://myfaces.apache.org/tomahawk-project/tomahawk12/tagdoc/t_jscookMenu.html is out of date. It is no longer necessary to...

  • Add jscookmenu directory containing css and scripting code to your web directory (you can find it in the examples application).
  • Add scripts and stylesheets for the theme you would like to use to html-header (see also inc/header.inc in the examples application)

... as these are now contained in the tomahawk jar. So I removed the aforementioned jscookmenu folder from the root of my webapp, as well as these from the head of layout.xhtml:

<!-- JSCook Menu -->
<script language="JavaScript" src="jscookmenu/JSCookMenu.js" type="text/javascript" />
<script language="JavaScript" src="jscookmenu/ThemeOffice/theme.js" />
<link rel="stylesheet" href="jscookmenu/ThemeOffice/theme.css" type="text/css" />
etc.

I also hadn't included *.jsp in my filter-mapping in web.xml, so I added as follows:

<filter-mapping>
    <filter-name>extensionsFilter</filter-name>
    <url-pattern>*.jsp</url-pattern>
</filter-mapping>

By now, the menu was rendering on the page.

When I then tried to navigate from one page to another, I got this error:

dummyForm.elements.jscook_action is undefined

, which I solved by adding this to admin.jsp, as suggested by http://forums.sun.com/thread.jspa?forumID=427&threadID=761310:

<input type="hidden" id="jscook_action" name="jscook_action" />

Hope this helps someone, as the JSCookMenu website is still down and help seems to be pretty thin on the ground elsewhere.
