I am creating an object named(obj1) of some calss on page1.jsp, storing it in request attribute, and forwarding to page2.jsp using jsp:forward action tag.
On page2.jsp I am fetching object obj1. Here I am able to fetch the obj1 successfully. Now my requirement is that , On page2.jsp on clicking of button I want to call page2.jsp and also want the request attribute which I set on page1.jsp.
I can do it using session or application scoped attribute, but how to do it using request attribute ?
My requirement is to upload a file from client(browser) to my Application Server (In any directory of Application Server machine like C:\ or D:\ etc..). But before that I want to check whether the file has any data or no ?
But on clients machine I cant do File operation using java.io package. Can anyone tell me how can I read file temporary without uploading it on server and check if file has any data so that I can give message to client like File has no data.
