Hi Muthu,
Download SetURL widget -> Drag & Drop this widget on the page which you want to show by URL -> Set the string url like ‘onlineapplication’ save & run the application.
Go to browser & check localhost:8080/p/onlineapplication
Did you see the docs here: https://docs.mendix.com/refguide/page-properties/#url ?
But do note that if the user is not logged in you will be directed to the login page but otherwise it will directly show this page.
Regards,
Ronald
