Hey there, I am very much a newbie to Drools, and I have been following the sample Application setup in the Drools Jboss Rules 5.0 developers guide. However, I am having some very very annoying problems with my persistence setup. My application is giving the following error, and then appears to use a default database jdbc:h2:mem:mydb, SEVERE: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed;

The setup I have following the book to the finest detail, and my transaction manager has been set up using the http://docs.codehaus.org/display/BTM/Tomcat13 site. Please can somebody advise me on where I could be going wrong? Is there something in the book that I am missing? I have put the h2-1.0.77.jar in both my classpath and in the lib directory of Tomcat6.
