servlet throwing exception in applet servlet communication

[Ashish Kulkarni <ku...@yahoo.com>]

Hi,

I am working on a project where i have a lot of applet
servlet communication,
I am using tomcat4.1.12 
Some times i get this error when sending data from
servlet to applet in log file, although there is no
problem and the data is passes properly.

what may be the reason
