Hello all,

I am using hibernate (hibernate3.jar) with mysql 5.0 through a JDBC driver with the mysql connector version 5.0.3. I have a problem with the stability of the connection. When I try to access to my JAVA application the session crashes and I need to restart the tomcat of my Linux machine.

The hibernate.cfg.xml I have configured:

Code:
<property name="hibernate.connection.driver_class"> com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url"> jdbc:mysql://127.0.0.1:3306/mydb?useUnicode=true&amp;characterEncoding=UTF-8</property>
<property name="hibernate.connection.username">XXX</property>
<property name="hibernate.connection.password">XXX</property>
<property name="dialect">com.myapp.hibernate.MySQLInnoDBDialectPlus</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.show_sql">false</property>
<property name="hibernate.cache.use_query_cache">true</property>


I have a HibernateSession class that controls the hibernate session. The crash happens in the get Session method:

Code:
public Session getSession() throws HibernateException  {
   LOG.debug("getSession init");
   try {
      if(session == null) {
   LOG.debug("session null");
   session = factory.getSessionFactory().openSession();
   LOG.debug("session:" + session);
            
   if(session.isConnected()){
      LOG.debug("session is connected");
   } else {
      LOG.debug("session is not connected");
   }
            
   if(session.isDirty()){
      LOG.debug("session is dirty");
   } else {
      LOG.debug("session is not dirty");
   }
            
   if(session.isOpen()){
      LOG.debug("session is opened");
   } else {
      LOG.debug("session is not opened");
   }
            
   transaction = session.beginTransaction();   
        LOG.debug("transaction:" + transaction);
      }
   }catch(HibernateException h){
            LOG.debug("HibernateException checking the session:" + h.toString());
            h.printStackTrace();
   } catch(RuntimeException r){
            LOG.debug("RuntimeException checking the session:" + r.toString());
            r.printStackTrace();
   } catch (Exception e){
            LOG.debug("Exception checking the session:" + e.toString());
            e.printStackTrace();
   } catch(Throwable t) {
            LOG.debug("Throwable checking the session:" + t.toString());
            t.printStackTrace();
   }         
   return session;
}


The catalina.out log of the crash is:

This exception is not due Hibernate.
The java.io.EOFException is raised by com.mysql.jdbc.MysqlIO.readFully(MysqlIO.java:1913) which is the jdbc-driver you are using.
There's apparently a problem in the communication between your driver and the Mysql database.
Please check if your Mysql-driver version is compatible with the Mysql database version.
Otherwise I suggest you to search in the
http://www.mysql.com/products/enterprise/knowledgebase.html
for this issue.

I have changed the JDBC driver and the problem persists, the driver is compatible with the mysql version I have installed. I will update the hibernate version in order to solve the problem.
