Threads provide functionality by implimenting thier run method. When the
run method exits the thread terminates. Your applet implements the
run interface so when after your (blocking) readLine() you exit. So
this is why you only get one line of text. You will want a loop to
get more lines.
Hope this helps,
Walt
P.S. you had a variable engine which was a instance of a plain vanilla
Thread. I don't think you need it.
