Hello, my goal is to use and manage Drolls Flow (start, stop ,....) through the gwt-console. I'm using Drools 5.1 M1. 1) Create the files users.properties, roles.properties in \drools -5.1.0.M1-guvnor-standalone\jboss-4.2.3.GA <http://jboss-4.2.3.ga/>\server\default\conf. also create the file 'testDS1-ds.xml' in \default\deploy 2) Download from http://www.mvnbrowser.com/ gwt-console-drools-5.1.0.M1.war and gwt-console-server-drools-5.1.0.M1.war. . copy these files in \drools-5.1.0.M1-guvnor-standalone\jboss-4.2.3.GA<http://jboss-4.2.3.ga/> \server\default\deploy 3) Start the jboss and handed me the following errors 2009-10-28 10:28:28,937 ERROR [STDERR] 28-10-2009
