This request / response works correctly while I implement the full method with request XML and call the Webservice, i.e. it works correctly. But requirement is --> there will be three webservice URLs (configurable from my Application by Admin User). First, I have to check whether the first URL one is connection or not. If Not connecting, then go

问题 I am attempting to download a jpg using HttpURLConnection and am encountering a very peculiar bug. Here's the url: http://www.vh1.com/sitewide/promoimages/shows/m/my_antonio/video/supertrailer/seg_1/320x240.jpg if you open it in a browser you will see the image. However, when I use HttpURLConnection I don't get the image...
