Hi , I am using JCChart in my project and using applet to display the chart. The chart is created at the client machine by the applet. now there is an option to export the image as a gif file of the chart to user, so when user click on export button then the image should be save in gif formate on the server. at server side as a scripting language I am using asp. Please tell me How can I save this image On the server directory by applet

and I have to follow the http protocole thats why I try it with HttpURLConnection but I become unable to directly save the image on the server directory please tell me the exact way so that I can save the image.

if there is any other better way to do this please tell me

Thanks and Regards

    So presumably you can create the gif file content using some feature of JCChart?

    Create an ASP component to receive HTTP POST connections accepting GIF images. Get it to write the body of received POST connections somewhere on your server. Where and how you do that is up to you.

    Use an HttpURLConnection set to use the POST method. Set the mime type according to http://silk.nih.gov/public/zzyzzap.@www.silk.types.html. Write the bytes of the image to the HttpURLConnection OutputStream.
