Hi Nommi, the above line tells you. You have data in your Java objec that is to long for the database column where it should be written.
Either increase your database column length or truncate the Java attribute.

Hi Nommi,

I'm sorry, but I cannot really help you, because your problems are not related to Hibernate (or other Java software) - as far as I can see.

Looking at:


I guess you really have heavy problems on the network layer!

hi carlof thanx fr reply but i figer out that what is actual happning with my application...

i read these forum to guess why it is happning to me

http://forums.mysql.com/read.php?39,199404,199404

http://www.michaelstudman.com/fullfatho ... -hibernate


what i do simple use these variable in mysql.ini configation file

wait_timeout=31536000
connect_timeout=31536000


i know it is not good idea but fr urgent use it is better fr me now i hope it would not be timout..

if u have any idea realted to hibernate to reconnect to DB if connection drop than tell me


i use these statement in the hibernate.confg.xml file but it not suported

<property name="connection.url">
jdbc:mysql://localhost:3306/epes?autoReconnect=true
</property>


thanx again fr reply ...
