Add this in your pom file:

<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.2</version>
</dependency>

Include hibernate jar files (especially the required jars) in your lib folder

antlr-2.7.7.jar
commons-collections-3.2.1.jar
dom4j-1.6.1.jar
javassist-3.12.1.GA.jar
hibernate-core-4.0.1.Final.jar
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
jboss-logging-3.1.0.CR2.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar
