Dear Ms/Mr, I have downloaded jbpm-install (jbpm-5.1.0.Final-installer-full) and installed jbpm by “ant install.demo”.,After I execute “ant start.demo”, However, seems to be going wrong when running the a web-based application like the jbpm-console, Guvnor and the Designer : I can’t access http://localhost:8080/jbpm-console and http://localhost:8080/drools-guvnor by Google Chrome or Firefox? What can I do? And when I use eclipse to store bpmn diagram into Guvnor, I can’t use the existent guvnor database, why ? I attachedto the mail screenshots of the errors and the jbpm-installer/ jboss-5.1.0.GA/server/default/log directory. Thank you for your response Best Regards -- REJEB.OLFA Doctorante /PhD student Centre Génie Industriel - Ecole des mines d'Albi-Carmaux Campus Jarlard - Rte de Teillet - 81013 ALBI cedex 09 Mail: olfa.rejeb@mines-albi Tél :+33 (0)5 63 49 32 66 -- REJEB.OLFA Doctorante /PhD student Centre Génie Industriel - Ecole des mines d'Albi-Carmaux Campus Jarlard - Rte de Teillet - 81013 ALBI cedex 09 Mail: olfa.rejeb@mines-albi Tél :+33 (0)5 63 49 32 66 -- REJEB.OLFA Doctorante /PhD student Centre Génie Industriel - Ecole des mines d'Albi-Carmaux Campus Jarlard - Rte de Teillet - 81013 ALBI cedex 09 Mail: olfa.rejeb@mines-albi Tél :+33 (0)5 63 49 32 66
