The following resolved the above issue for me. I have TomCat 7.0.34 installed with 5.4.0 Final of Guvnor.

You can disable the seam transaction listener by adding appropriate <context-param> to the web.xml file that you should find in

[tomcat-dir]\webapps\[nameOfGuvnorJar]\WEB-INF\

where [tomcat-dir] is your top level directory path to where you have installed Tomcat. and [nameOfGuvnorJar] is the name you gave to the guvnor application that you have deployed in Tomcat.

The lines required are

<context-param>
   <param-name>org.jboss.seam.transaction.disableListener</param-name>
   <param-value>true</param-value>
</context-param>

It needs to be added inside the <web-app> element

You will probably need to restart the webserver for the change to be picked up.

Thanks! That solved the problem. By the way, no need to restart the server if Guvnor is deployed in vfabric-tc-server-developer-X.X.X.RELEASE/base-instance/webapps. – Insobriety
