I see the following error in the log:
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.Connection was implicitly closed by the driver.
I have reduced the wait_timeout in my.cnf to 60 Should I set the default value for this parameter? I am told my Java Programmers that this may be one of the reasons.
I've had a same exception as yours, I think you did some operations after you closed the connection.For example:
{
try{ Connecton conn = DriverManager.getConnection(...);
....
....
....
conn.close();
conn.commit();//Any operations on conn after conn.close() will throw //com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException
}catch(Exception e){
...
}finally{
...
}
}
The example shows how the exception come out.I think you did something like it does.
