Hi,
never used mysql (so take this with a pinch of salt ;-)), but it seems that by default reconnected connections set to 'read-only' mode. Did you try to set failOverReadOnly=false
http://dev.mysql.com/doc/connector/j/en/index.html#id2423002
In jdbc-connection-descriptor you should set useAutoCommit="1", this guarantee that all connections returned to pool set with autoCommit 'true'. Only in this case autoReconnect seems to work in mysql.
http://db.apache.org/ojb/docu/guides/repository.html#useAutoCommit
If you don't have succeed in doing so, you can specify a 'validatioQuery' to check connection before delivered by the connection-pool
http://db.apache.org/ojb/docu/guides/repository.html#connection-pool-N10230

I reproduced the exeption by stopping and restarting the sql server.
the probleme is that OJB dont auto-Reconnect in spite of putting in my repository.xml in the connection declaration dbalias="//localhost/MyDB?autoReconnect=true"
How can i tell to OJb to auto reconnect?

Subject: org.apache.ojb.broker.PersistenceBrokerSQLException
Hi all,
I have a SQL probleme, it seems like the connection died after some time, it happen only for the OJB connection, because I have another connection that use classic java connection managed with a connection pool, this kind of connection dont throw any exception at the same time the ojb connection throws that exception.
Did anyone had the same problem?
