Getting error during SessionFactory creation

I keep getting failed.org.hibernate.HibernateException when I want to run my hibernate code. I'm using Spring 3 MVC and Spring 3 security in my app. Any idea what can cause this?

Hibernate part of pom.xml:

<!-- Hibernate + MySQL -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.9</version>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>3.6.3.Final</version>
    </dependency>

    <dependency>
        <groupId>javassist</groupId>
        <artifactId>javassist</artifactId>

    <dependency>

        <groupId>antlr</groupId>
        <artifactId>antlr</artifactId>
        <version>2.7.7</version>
    </dependency>

The stack trace:

    <version>3.17.1-GA</version>
</dependency>
