hi, Even i faced the same problem while deploying the 3.1 version of jbpm on tomcat! but finally made it on tomcat. My tomcat version was 5.x and used Oracle 9i as backend! Here are the steps i followed to deploy 3.1 version of jbpm on tomcat. Download jbpm-starters-kit-3.1.1 from Jboss site Deploy jbpm-starters-kit-3.1.1\jbpm-server\server\jbpm\deploy\jbpm.war into tomcat webapps. Copy hibernate.cfg.xml from jbpm-starters-kit-3.1.1\jbpm\src\config.files to ur <jbpm-home>/WEB-INF/classes/ Run ant task for creating database tables and data from jbpm-starters-kit-3.1.1\jbpm\build.deploy.xml ( ant create.db ?buildfile build.deploy.xml) Add few jars to lib folder of your application. Start tomcat. Start jbpm application. thanks and regards diwa View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969162#...
