Hello,
I've been try to write a simple Applet / Servlet combo that can communicate with each other and I've hit a problem. When, from the Applet, I open a URLConnection to the Servlet running on tomcat, all seems to go well. However, when I go the further step to try to get an inputstream from the connection, I get the following error:
java.security.AccessControlException:
access denied(java.net.SocketPermission localhost resolve)
I'm wondering what is really going on here. Is the problem that I'm viewing the Applet page as a localhost? Do I need to change the configuration of tomcat?
Any help or advice would really be appreciated.


Fun programming etcetera!

The problem is that Java SandBx does not allow a simple applet to communicate for such security issues...there are two workaround:-
1. Make your applet signed one...the other problem here would be signing separately for Netscape and IE...can get some info on net for same...I had some link will post ASAP
2. Perhaps other way is to make another class in applet as standalone app and than communicate through this to Servlet...
Hope this may help...all the best

regards,
arun
