You should post this to the GlassFish forums.

This was cross-posted in the sun forums. I've already answered there.

The locale is changing (checked with c:out) but messages aren`t.
The funniest thing happends when i change language to english and check the chceckbox - All messages change to english and the jstl locale variable is emptied (c:out doesn`t write anything out).

This example worked with jsf1.1.5 but it doesn`t work with jsf 1.2.
Can any one tell me why??

I enclose the code of this example:

I`ve tried to download new jstl.jar and standard.jar, add tlds and declarations in web.xml but it didn`t help.

If anyone knows answer to this mystery please help.

Please let me know what i am missing.

Might try following up with the tomcat folks. Something seems wrong with your installation now.

Originally posted by M Burke:
I am new to faces. I want to build a table from a collection of objects, and make a link for each to open that item on a different form.

In the past, I added request parameters to my links to know which one is clicked. Like this: a href='view.jsp?row=1&col=1' then do a request.getParameter('row') in my servlet.

How do I do this equivalant in JSF? I can't even find any examples of a faces action even accessing the request object.

I'd recommend going through these tutorials: http://balusc.blogspot.com/2006/06/using-datatables.html

Hi,
Is it possible to access the <body> element from a managed bean?
I want to add the "onLoad" attribute programmatically.
<body id="body"> <f:view> <h:form id="form">


UIComponent body = (UIComponent) facesContext.getViewRoot().findComponent("body");

The statement above returns null. I guess this is because the ViewRoot contains JSF-Components only?

Thanks in advance.

In short yes. If you want to have access to the 'head' then you need a head component. It would be simple to write one, though component libraries such as woodstock [1] have a head component.

Additionally, JSF 2.0, there will be a basic head component included.

[1] https://woodstock.dev.java.net

I'd ensure that there are no other instances of jsf-impl within the tomcat installation (i.e. server/lib or common/lib).

Hi,

I want to use JSF 1.2 @PostConstruct annotation and for that i have downloaded latest version of JSF i.e. JSF 1.2 and also i configured Tomcat 6.x.x in my MyEclipse, but when i am using @PostConstruct in Bean it is giving compile time error,, it is not recognizing that package,,, can you please help me out...What i am missing???

Thanks,
Gaurav

You need to include the common-annotations jar in your compilation classpath. You'll also want to include said JAR with your application,
otherwise you'll have runtime issues.

Also, when posting versions, JSF 1.2 is a spec version. There are two common implementations of the specification in the wild right now. It's useful to include which implementation and version.

Originally posted by Cameron Wallace McKenzie:
Indeed...I was looking at the phase listener.

I guess you could achieve something similar with a ServletListener configured on the FacesServlet.

Looks like we're not the only ones hitting this conundrum. Seems JSF 1.2 has a solution, developed by people better looking than you and me.

Unfortunately, I'm deploying to Rational Application Developer, and IBM has a policy of not supporting new standards until they are extremely old.

If using JSF 1.2, look at the beforePhase and afterPhase attributes provided.

Refer to the discussion in the following link

NOTE: f:verbatim isn't necessary if using JSF 1.2 in combination with JSP 2.1.

In your scenario, what if I were in Page B prior to my visit in Page A? Then When I come back to Page B, this page has no state, because no state of no page is saved on the session (i.e., on the server).
But when I was in Page B on the 1st time, I did change its state to be different than its default state. So where was it saved in your algorithm?

When you change the state of PageB, then the state change will be present in the saved state of PageB. The saved state of one page has no impact on the saved state of another page.

I'd like to recommend you spend some time reading the specification if state saving is of interest to you.

Actually, you're not.

The state for PageA will be valid only for PageA.
When you submit the form, the state is used to reconstruct
PageA, apply the form data, and then navigate to PageB.
PageB's hidden field will only contain data relevant to PageB.

I don't think that these are part of JSF - they're part of the JSR-250 lifecycle spec.

Spring supports these annotations, I believe.

The JSF 1.2 spec requires support of these annotations in a Java EE 5 environment. That said Mojarra (the RI) supports these two annotations
outside of an EE environment if the annotations are present in the classpath.

As to their explanation, it's pretty straight forward.
Methods marked with the @PostConstruct annotation will be invoked after the bean has been created, any resources have been injected, and any managed properties set, but *before* the bean is actually pushed into scope.

Methods marked with @PreDestroy will be called before the bean has been
removed from scope.

It looks like your WAR is missing an XML DOM library used by the Sun JSF code.

The JAXP implementation in JDK 1.5 and above will work fine with the RI. That said, older implementations of Tomcat provided their own JAXP implementation and overrode the JDK. If this is one of those Tomcat versions, then overriding the JDK's jaxp is going to cause failures.

I'd recommend posting the JBoss forums. Hard to tell what's going wrong in all that mess.

Thanks,
Ravindra.

Would be helpful to have the exact version of Tomcat 5.x you're using.
I just tried using Tomcat 5.5.25 and the application deployed.

Also note, if you are using Tomcat 5.x, you *must* be using Facelets and not JSP.
If you're using JSP, then you *must* use Tomcat 6.x.
