Same problem here. The Hibernate pom should have a runtime dependency:

<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
<scope>runtime</scope>
</dependency>

Or is it an optional dependency?

<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
<optional>true</optional>
</dependency>
