Hi,

        I've been getting this exception a lot now. It sometimes happens
after some of the statements in the script have been executed (as
reflected in the database). The only way to continue once this happens
has been to restart tomcat. Does anyone have any ideas as to why this
is happening ?
        I didn't see any problems with mysql.

Thanks,
Shishir
