Description of problem:
To get BRMS 6.1 working on Tomcat, the following libraries need to be copied to $TOMCAT_HOME/lib:

• btm-<VERSION>.jar
• btm-tomcat55-lifecycle-<VERSION>.jar
• h2-<VERSION>.jar (or other DB driver)
• jta-1.1.jar
• slf4j-api-<VERSION>.jar
• slf4j-jdk14-<VERSION>.jar
• kie-tomcat-integration-<VERSION>.jar
• javax.security.jacc-api-<VERSION>.jar

These binaries are not bundled in jboss-brms-6.1.0.GA-deployable-generic.zip

Additional info:
This has already been reported in https://bugzilla.redhat.com/show_bug.cgi?id=1201555, and set to verified with the CR1 release, but is still an issue in the GA package.
