Hi, Please I need your help on this one. I keep getting the following exception on Tomcat (both 6 and 7) when running Guvnor. I can deploy it without problem, but when I hit the URL (http://localhost:8080/drools-guvnor/) the error message is printed on the Tomcat console and a 500 error message ( 500 The call failed on the server; see server log for details) is displayed in the browser. What am I missing in the installation process? Thanks, Klaus.
