page refresh problem

[Madhav Bhargava <Ma...@infosys.com>]

Hi All,



Following is the layout of my web page:



1.	Left navigational menu which contains collapsible menu items.
2.	Top header which I static.
3.	Content section.



The content section in many pages is composed of several tabs.



Consider a scenario:



1.	User clicks on the left nav and goes to a particular page
containing many tabs.
2.	The user selects a tab, enters search criteria to fetch data and
fires a search.
3.	The business layer in turn uses an EAI engine to gather relevant
data from a federated database. This might take a bit of time.
4.	When the results come then they are displayed to the user.





To implement the same the following approach has been taken:



1.	When a request is fired then in the business layer an API call
is made to the EAI to fetch data.
2.	The EAI engine writes the data to a local repository and sends a
notification message over a socket.
3.	A servlet acting as a socket listener listens to any
notification and puts it on to a JMS queue.
4.	MDB's are invoked to handle any notification. Upon receiving any
notification then make a database call to fetch relevant data.
5.	Response is then put on to a response Queue.
6.	The refresh page request fired from the client will call a
particular method in the managed bean. Upon receiving the refresh
request the action method will look into the response Q for any response
for the request. It a response message has arrived then it will get the
message and show the results to the user.





The problem



How do you auto-refresh a page and call a particular method which is
handling the opened tab inside a page? Unfortunately the URL that is
shown never seems to change after the user has made a selection on the
left navigation menu. The action method which was called when the user
selected the left nav menu item is still getting called on every refresh
if META refresh tag is used.



I do not want to involve javascript because if I use javascript to show
a progress bar using AJAX then it will not work if javascript is
disabled in a browser.

Why the URL does not change even after different action methods are
called?



How can I refresh the page with the selected tab opened without
javascript?



Thanks & Regards,
