Hi dudes,
I'm working on JSF,Hibernate,& Spring in my project.
I'm loading data for my JSF through my backing bean.
When using ajax in my JSF, I don't get what is the use of this a4j:region
and what is the difference between h:commandButton and link and a4j:commandbutton and link.
Also when i want to pass parameters to my backingbean which will be better a4j:parameter or h:paramname
Come dudes I'm waiting for your reply.

Regards.

"Dudes"? :roll:

I've got a suspicion that you didn't read our rules on using real names (http://www.javaranch.com/name.jsp), but I'll let someone else worry about that.

The a4j tags are for AJAX-enabled RichFaces support. An a4j:region is simply a block of page source that can be made the target of an AJAX operation such as partial page refresh. Except for the AJAX, it's a lot like the HTML <span> tag.

Likewise the aj4 command and link tags are like their core JSF equivalents, except that they provide attributes that permit them to be used to perform AJAX operations.


Customer surveys are for companies who didn't pay proper attention to begin with.
 
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
