com.mysql.jdbc.PacketTooBigException
Packet too Big Exception originates from MySQL when the packet of data is too big for MYSQL to handle. com.mysql.jdbc.PacketTooBigException: Packet for query is too large (4739923 > 1048576). After a whole day of nerves wrecked for this, I figured out that i need to increase the size of "max_allowed_packet variable" in two places at the client's and server's end - as stated by MYSQL (http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html) mysql> show variables like '%max_allowed_packet'; mysql> set global max_allowed_packet=52428800; File: /etc/my.cnf max_allowed_packet=50M The maximum allowed packet size is 1GB ie 100MB. Oh btw, 1 MB = 1048576 bytes. And viola, then restart the server. /etc/init.d/mysqld restart && tail -f /var/log/mysqld.log Yeah ! problem solved...
