I have a applet which communicates with a servlet.
When my applet attacks my servlet and when my servlet is installed on the same machine (, the communication is done without problem. But, when the servlet is installed on a another machine ( I've a java.security.AccessControlException. I work with jdk 1.3.1 and i've tested with jdk 1.1.8 and all works!! I suppose that my problem is with jdk 1.3.1.
below sources:


The exception

I've tried also with a simple application in the place of a applet and that works!!
How can i resolve that?
Thanks for your help

The exception you are getting is exactly what one would expect. Normal Applet security policy enforced by the browser prevents accessing data from another server. I think you would have to use a signed applet.

Correct. In fact, unsigned applets are forbidden to open ANY sort of network connection to any place other than the server that they were loaded from.

Customer surveys are for companies who didn't pay proper attention to begin with.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
