Hello Chandra,
Put the following javascript in your JSP...

<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
	setTimeout("location.reload(true);",timeoutPeriod);
}
//   -->
</script>

Merry Christmas...

Hope this will help...

Thanks and Regards...

Ajax can help in this case.

Use the method with some modifications like this

<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
   // setTimeout("location.reload(true);",timeoutPeriod);
// make a ajax call here. If you are using jquery then
$.post('<portlet:renderURL windowState="<%= LiferayWindowState.EXCLUSIVE.toString() %>"></portlet:renderURL>', function(data){
    $("#myportlet").html(data);
})
}
timedRefresh(5000);
//   -->

</script>
<div id="myportlet"></div>

The original post is 8 years old. It's 2020. If you have a portlet that dynamically updates, consider using renderrequests, headless api access from the frontend or similar.
Consider a scenario where you're entering data into a form in another portlet on the same page, while someone thought it might be a good idea to reload the full page. You'd not be a happy user. Don't be that "someone" who causes unhappy users. As a developer you're responsible for your portlet's content. The page is somebody else's business.

I'm questioning that... maybe you'll need to do that to your portlet...
And if it's that, the solution depends on the implementation of your portlet: Is it a server-side implementation? A Javascript-heavy implementation?
Updating/Refreshing dynamically typically involves some amount of JS, but if you start out fully headless and on the browser side, the answer will be different than if you started a server-side JSR-286 implementation.

Describe your situation and requirements - what is the underlying problem that you're trying to solve. And check my post above for sentences ending in a question mark

well, that part  was clear, but the underlying problem isn't. You've come up with a solution to auto-refresh. But we don't know what you'd like to refresh: A custom portlet's content (e.g. database content)? A content article? Some out-of-the-box content?
What's the business case? Apart from just triggering a page reload (which you could easily do with a bit of JS any time, at the cost of interrupting anyone currently working on a form on the page)

and if i want to do the JS method how i can do this?

I want to auto-refresh to the main page of portal because the notification can't appear to the user until he reload the page

I bet that if someone can show you a way to just show the notifications (your business requirement), you won't care much about the page being refreshed (your proposed solution).
That's why I'm always asking about the underlying business problem.
Now that this is clear, let's see if someone already solved this problem. I bet there's an API that one could trigger dynamically (e.g. under /api/jsonws) that reveals the number of notifications. It "only" doesn't seem to be utilized in the default implementation, but that's the direction that I'd go.
A trivial option is to write your own NotificationPoller portlet that polls&displays the notifications dynamically. A more elegant version would use the same signalling that Liferay uses. As I'm not your typical go-to-person for frontend questions, I'm leaving the concrete idea for someone else for now.

No i don't want a way to just show the notifications ,i want a way to reload the page to see new notifections

I still stand by my claim from above. But as you ask about it: The notifications will automatically be correct on reload, so you'll need this technique.

i think i can't understand u very well because my english language it's not very well,so please can u explain your idea in simple way?and i have another question ,i need liferay sdk plugin 7.2 put when i search about it i can't find it can u help me to find it?i'm so sorry sorry for disturbing you

[Olaf Kock, geändert vor 3 Jahren.]

My question is:
1. Do you want the notifications to appear?
OR
2. Do you want to reload the page?

Number 1 is a business problem. Number 2 is a technical question.
Especially if you say "I need 2 because 1" - that's called XY-Problem http://xyproblem.info/
You've insisted on needing 2, that's why I gave up on providing a solution for 1.

Liferay has a rich API, which you can inspect and find the way to obtain the number of notifications, through Javascript Ajax-requests. And then make use of the result any way you like. It'll require some programming skills, and we don't know about your experience level.
If someone here provides code snippets, they might be helpful or distracting - again: Because of the xy-problem: Code snippets are solutions. And often they're solutions to other problems than yours.
