Hi all,

I have two tomcats with same web applicattion running on two machines. They have Persistent sessions by Postgresql Database.

When I initialize two tomcats and i load page all goes okey. Apache redirects request to tomcat1 or tomcat2. Problems come in this case:


- Initialize two tomcats with its owns hibernate Sessions.

- Web Access to Apache. It redirects requests to, for example, tomcat1.

- Session is inserted into database tomcat_sessions table with hibernate session object thanks to session in view implementation.

- Stopped Tomcat1 before session expires (forced by me).

- In same web session try to do something, for viewing that tomcat2 take control of that session and continues request from that session but... ERROR!!!



I think this is because when you stop tomcat1 and tomcat2 tries to get SessionFactory, its session factory hasn't this id. I was thinking about binding SessionFactory to JNDI in order to have same names to each one tomcat but... Context is read-only in tomcat.

Any ideas?

Best regards

Yes, session factories in both Tomcat's should have the same name, the message you see is just a warning telling that there is no serialized instance of the session factory found. Makes sense...
SessionFactoryImpl::

private Object readResolve() throws ObjectStreamException {
log.trace("Resolving serialized SessionFactory");
// look for the instance by uuid
Object result = SessionFactoryObjectFactory.getInstance(uuid);
if (result==null) {
// in case we were deserialized in a different JVM, look for an instance with the same name
// (alternatively we could do an actual JNDI lookup here....)
result = SessionFactoryObjectFactory.getNamedInstance(name);
if (result==null) {
throw new InvalidObjectException("Could not find a SessionFactory named: " + name);
}
else {
log.debug("resolved SessionFactory by name");
}
}
else {
log.debug("resolved SessionFactory by uid");
}
return result;
}
