Jbpm-console seam to be a very good starting point if we need to write an application that allow user to deploy is own defined processes. In order to package the jbpm-console with additional feature specific to our customers, I plan to benefit for the ease of development that seam allows. I have written some small seam application. Then, I try to integrate the seam jar and required configuration in web.xml, faces-config.xml seam.properties... Since then, the jbpm-console seems to work fine (I am able to initiated process, complete task ...). However, I keep getting the stack trace, which will follow, for almost every action I perform in the jbpm-console. Do you have an idea how to fix this? The stack trace is something I have tried to fix. However, since the application seems to work fine, I have tried to use backing bean. I still have some problem (probably due to my short experience with seam) but I have been able to use the websale demo and add a call to a backing bean in the form.create.xhtml file. For now I have add to put my backing bean directly into the WEB-INF/classes/… folder. Does anybody have tried to have the seam backing been versioned in the par file like the action handler and forms are? thanks in advance for you precious help, An Phong Do I have added the stack trace add content of configuration files here. 07-12-05 08:17:03,578 DEBUG [org.jbpm.persistence.db.DbPersistenceService] rolling back hibernate transaction 2007-12-05 08:17:03,578 DEBUG [org.hibernate.transaction.JDBCTransaction] rollback 2007-12-05 08:17:03,578 DEBUG [org.jbpm.persistence.db.DbPersistenceService] closing hibernate session 2007-12-05 08:17:03,578 ERROR [org.jbpm.svc.Services] problem closing service 'persistence' org.jbpm.persistence.JbpmPersistenceException: hibernate commit failed at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:219) at org.jbpm.svc.Services.close(Services.java:225) at org.jbpm.JbpmContext.close(JbpmContext.java:139) at org.jbpm.jsf.core.phase.JbpmPhaseListener.closeContext(JbpmPhaseListener.java:94) at org.jbpm.jsf.core.phase.JbpmPhaseListener.afterPhase(JbpmPhaseListener.java:45) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:280) at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:144) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:245) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:83) at org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:58) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:85) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:64) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:44) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:524) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619) Caused by: org.hibernate.TransactionException: JDBC commit failed at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:130) at org.jbpm.persistence.db.DbPersistenceService.commit(DbPersistenceService.java:256) at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:214) ... 38 more Caused by: java.sql.SQLException: You cannot commit during a managed transaction!
