I've also been having problems in Tomcat 3.1 with mouse rollovers. Is
that a known issue in 3.1? If so, I'm sorry I missed it. If not, read
on...
I noticed the problem when I was using IE 5, with its caching policy set
to check on every usage. With a less frequent setting, the images get
cached once and there's no problem. But with the high-frequency setting,
IE fetches the image anew on every rollover (I'm using Tomcat standalone,
and 3.1 never emits anything to indicate that anything is cacheable, as
far as I can tell).
I could do a lot of rolling over. But eventually I'd get the following
printed to stdout/stderr from Tomcat:
java.net.SocketException: A connection is ended by software.
at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:423)
at java.net.ServerSocket.implAccept(ServerSocket.java:191)

Endpoint ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8085] shutdown
due to exception: java.net.SocketException: A connection is ended by
software.
and then Tomcat would be wedged --- no clients would ever make any more
progress.
