I am trying to execute a simple applet program in Java. I have compiled the .java file of the code successfully but, when I try to execute the .html using the command appletviewer sourcecode.html, I get the error,
"No X11 display variable was set, but this program performed an operation which requires it."

Your program seems like it was written to be stand-alone, and pop up a GUI. When you try to run it, it's looking for an X server, so it can display the windows. Your browser doesn't know such things, so you get the error.
I know i am digging on to a very old question here.
However i am facing a similar kind of problem when i am trying to run the xuggler media container code using my servlet application.
Any idea where i can look for in my code and what type of thing should not be there in the code so that such error does not pops up.
