Atomikos Forum

I read about Atomikos integration with Tomcat7 and Hibernate both separately,but when i tried to integrate with both of them ,i confused specially about jndi.properties "org.apache.naming.java.javaURLContextFactory" not found in Tomcat 7 ,then i tried to get naming-factory.jar but i get

java.lang.NoSuchMethodError: org.apache.naming.ResourceRef.<init>(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Z)V
    at org.apache.catalina.core.NamingContextListener.addResource(NamingContextListener.java:994)
