    copied!<p>I've done quite a bit a research on this with no luck, but all the answers have a tendency to point toward the session context settings in the config file. What is odd is that I get a session connection the very first time I hit the page (and therefore, a successful result set), but then when I reload I get the following exception: org.hibernate.SessionException: Session is closed!</p> <p>Here are my config settings that are not DB connection string related:</p> <pre><code>&lt;property name="hibernate.show_sql"&gt;false&lt;/property&gt; &lt;property name="hibernate.dialect"&gt;org.hibernate.dialect.SQLServerDialect&lt;/property&gt; &lt;property name="hibernate.current_session_context_class"&gt;thread&lt;/property&gt; &lt;property name="hibernate.cache.provider_class"&gt;org.hibernate.cache.NoCacheProvider&lt;/property&gt; &lt;property name="hibernate.cache.use_query_cache"&gt;false&lt;/property&gt; &lt;property name="hibernate.cache.use_minimal_puts"&gt;false&lt;/property&gt; </code></pre> <p>Here is an example of a call I make that produces the situation I described above.</p> <pre><code>public T get(int id) { session.beginTransaction(); T type; try { type = getTypeClass().cast(session.get(getTypeClass(), id)); } catch (ClassCastException classCastException) { throw new ClassCastException(classCastException.getMessage()); } session.getTransaction().commit(); return type; } </code></pre> <p>The session variable reference is to a static field that contains the current session. All of the session connection details are textbook reference manual. For example, here is my Hibernate session utility:</p> <pre><code>import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class HibernateSessionFactoryUtil { private static final SessionFactory sessionFactory = buildSessionFactory(); private static SessionFactory buildSessionFactory() { try { return new Configuration().configure().buildSessionFactory(); } catch (Throwable ex) { System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } } </code></pre>
