Comments on: AJAX Upload progress monitor for Commons-FileUpload Example

I am using apache file upload libraries. Have it running beautifully, except for one problem: For files that exceed specified limit we want to return immediately. The browser keeps sending data even though the servlet has closed the response stream and returned. This is a major issue for us as this experience is not acceptable to business.
I see a similar post above too. Anyone figured this? Apparently browser and server are still communicating even though the application has responded.

Thanks for this. Just what I needed. I’m not done implementing this in my application yet, but after playing around with it, it seems simple.

Hi plosson!!

Thanks a lot for a such a nice piece of working example but I have a few problems, if you or somebody can help me.
Actually the from action has been set to “upload.jsp” but in my spring-driven application I want to send my JSP directly to the controller, let me tell you the options I have tried out,

1- I didn’t set the action for this form after placing the java code inside “upload.jsp” into the targeted controller, so it went directly to my controller (which I wanted it to) but the progress bar never moved.

2- I kept the action to “upload.jsp” and did a jsp:fwd to my controller.The progress bar ran ok but the controller lost my model object being forwarded from the JSP.

I have already spent lots of time on it trying various ways but to no avail, please can you help me out a little here?

Cheers,
Kamran.

Hi, Thanks for your tutorial .. it helps me a lot
anyway I tried to copy upload.jsp into some servlet, and it’s not working.
anyone had tried before ?

or maybe this is why you wrote like this
“The example has been kept to the strict minimum to be self explanatory and it not supposed to be used as is .. (java code is a JSP aarrrggg …).”

I am trying to use this progress bar implementation in my own web application which has it’s own file upload part. But I couldn’t find some of the .js files that has been used in the .jsp pages of the web upload sample given above. Where can i get those UploadMonitor.js, engine.js, util.js files and all.

Any help will appreciated greatly.

thank you,
Bhuvana.
