When i copy and paste and below in browser url, i am able to view the all the properties of appletviewer.

http://11.22.33.44:9080/my_app_context/AppletPak/jsp/viewer/../../ViewerGetConfig?

I dont know where i am missing it. No logs at server end. I think, at browser stage it is getting restricted by some security. I am using IE11 for the same. IS there any issue with servlets deployments ??? First thing is it is not reaching server as far i know.

Your suggestions are more valuable. Thanks for your support.

  • Hi Thanks for your reply. But, i have enabled java applet in IE under security. Still i am getting the same. – Naresh Oct 23 '15 at 05:52
  • One more input like, it actually failing at input = urlConnection.getInputStream(); . I tried with few sample URL's like google.com and i am getting response back to my code. But with my application URL as mentioned above , i am getting IOException. Do i need to add anything in web.xml of my war file.. – Naresh Oct 23 '15 at 05:56
  • What type of authentication scheme are you using on the server side? Basic? Some type of single sign on? – Brian Ochs Oct 24 '15 at 01:10
  • Its basic. Because in login page itself i had singlesignon check box and i am not check in. So, singlesignon is false. It should be basic. I suspect the URL here.Is ../ is allowed in URL ??"http://11.22.33.44:9080/my_app_context/AppletPak/jsp/viewer/../../ViewerGetConfig". – Naresh Oct 24 '15 at 05:21
  • Any observations from any one ??? – Naresh Oct 26 '15 at 05:45
  • I have observed this in logfile. "". This is the last statement i am getting and after thereafter i am getting error – Naresh Oct 26 '15 at 06:52
