Has anyone had to upgrade from Tomcat 3.1 or 4.0 TO Tomcat 4.1.x or 5.0.x
ONLY to get an IO EOFException when transferring a serialized object between
an Applet running (JVM) 1.1.8 and servlet (JVM 1.4.0).

I'm hoping that Java 2 is still maintaining object serialization backward
compatibility.  I smell a potential conflict based on different JVM
serialization architecture.  Please inform for the sake of others with this
same problem. I'm sure others are having this problem.  Maybe I'm too stupid
to see the problem :-)

Thanks to all that contribute to the help in advance,
-Alan
