Having problem with image upload....
1 Answer(s)      2 years and 6 months ago
Posted in : JSP-Servlet


I am uploading profile pictures in my site.But after uploading when I visit my home page where it is supposed to show my profile picture,it's not showing.My profile picture is getting uploaded successfully and there is no doubt about that because I checked on the server that the image is getting uploaded.I also right clicked on the home page and went through it's source.At the place of my profile picture I found the url of the image absolutely correct.But when I click on the url it is saying requested resource is not found on server.The same problem is occurring in case of updating.Getting updated my profile picture successfully but not showing while the url is correct.I have renamed the image after uploading with time stamp so as to prevent caching problems.Please help me.I am using JSP.
