I you install the default installation package and use "ant start jboss" when you first test the installation and load data into guvnor, then there are a good chance that you will see this error when you later start the jboos server through another means, from with-in eclipse or directly in say ${jboss.home}.bin The reason is that Guvnor install the repository.xml and repository in the start-up directory. This can easily be fixed in the build.xml file by adding the dir="${jboss.home}/bin" in the ant exec command. I hope this help  -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/726210#726210] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
