I have a written a
servlet, pretty standard, which provides a
jsp file.
I have an
applet embedded in the jsp file with applet which performs this code on a button press:
This code works fine if in a standard
Java program but if in the applet I get this error:
appletviewer chat.jsp

Do I have to perform the POST differently in an applet?
Is there any way I can POST data to the servlet using an applet?
