We encountered a big problem on the session. In our program, we use org.quartz.Job,
According to treat about 900 lines of file, it affichie an error as "Session is closed." If we implementong interface
org.quartz.StatefulJob it trailte about 3000 lines, then it makes the same mistake. We tried to change the properties of hibernate in
the file 'persistence.xml', for example


Thanks
