Hello,

I'm facing this problem, and i didn't find any other case on the internet.What could it be?
It's strange because it happens only sometimes.

Code:
Caused by: org.hibernate.HibernateException: 'hibernate.dialect' must be set when no Connection available
   at org.hibernate.dialect.resolver.DialectFactory.buildDialect(DialectFactory.java:107)
   at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:142)
   at org.hibernate.cfg.Configuration.buildSettingsInternal(Configuration.java:2163)
   at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2159)
   at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1383)
   at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:954)

This error was throwed because I was using the configuration programatically...
Now I'm configuring the session factory with a xml configuration. It's right now.

But Why?? Why this error is throwed using the configuration programatically??
Is it a hibernate bug?

We are out of luck. A ticket has been opened but is not closed:

I was having the same error, my code to create session was as below
AnnotationConfiguration cfg = new AnnotationConfiguration()

annotedSessionFactory = cfg.buildSessionFactory();

Below is the modified code which solved the error

AnnotationConfiguration cfg = new AnnotationConfiguration().configure();
//cfg.addAnnotatedClass(hello.Message.class);
annotedSessionFactory = cfg.buildSessionFactory();
