How to use jBPM built-in components?
I want to use Seam built-in components to deploy a xml file with a process definition. My code:
@Name("workflowHome")
@Transactional
public class WorkflowHome extends EntityHome<Workflow>
{
@RequestParameter
Long workflowId;
private Workflow workflow;
@In(required=false)
Discipline discipline;
@In(value="org.jboss.seam.core.jbpm")
private Jbpm jbpm;
@In(value="org.jboss.seam.core.jbpmContext",create=true)
private JbpmContext context;
@Override
public Object getId()
{
if (workflowId==null)
{
return super.getId();
}
else
{
return workflowId;
}
}
@Override
public void create() {
super.create();
}
@Factory("workflow")
public Workflow initWorkflow(){
return getInstance();
}
protected Workflow createInstance() {
workflow = new Workflow();
discipline.getWorkflows().add(workflow);
return workflow;
}
public void deployProcess(){
String file = new String(workflow.getWorkflowFile());
try{
context.deployProcessDefinition(jbpm.getProcessDefinitionFromXml(file));
}finally{
context.close();
}
}
}
What am I missing? Because I'm getting the following exceptions:
03:08:44,372 ERROR [PhaseListenerManager] Exception in PhaseListener RENDER_RESPONSE(6) beforePhase. java.lang.IllegalStateException: Could not commit transaction at org.jboss.seam.jsf.AbstractSeamPhaseListener.commitOrRollback(AbstractSeamPhaseListener.java:306) at org.jboss.seam.jsf.TransactionalSeamPhaseListener.handleTransactionsAfterPageActions(TransactionalSeamPhaseListener.java:47) at org.jboss.seam.jsf.AbstractSeamPhaseListener.enterPage(AbstractSeamPhaseListener.java:258) at org.jboss.seam.jsf.AbstractSeamPhaseListener.beforeRender(AbstractSeamPhaseListener.java:192) at org.jboss.seam.jsf.SeamPhaseListener.beforePhase(SeamPhaseListener.java:53) at org.apache.myfaces.lifecycle.PhaseListenerManager.informPhaseListenersBefore(PhaseListenerManager.java:70) at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:373) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:138) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.seam.servlet.SeamMultipartFilter.doFilter(SeamMultipartFilter.java:35) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.seam.servlet.SeamRedirectFilter.doFilter(SeamRedirectFilter.java:32) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.seam.servlet.SeamExceptionFilter.doFilter(SeamExceptionFilter.java:46) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595) Caused by: org.jboss.tm.JBossRollbackException: Unable to commit, tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=desktop/102, BranchQual=, localId=102] status=STATUS_NO_TRANSACTION; - nested throwable: (org.hibernate.SessionException: Session is closed!) at org.jboss.tm.TransactionImpl.commit(TransactionImpl.java:372) at org.jboss.tm.TxManager.commit(TxManager.java:240) at org.jboss.tm.usertx.client.ServerVMClientUserTransaction.commit(ServerVMClientUserTransaction.java:140) at org.jboss.seam.jsf.AbstractSeamPhaseListener.commitOrRollback(AbstractSeamPhaseListener.java:295) ... 36 more Caused by: org.hibernate.SessionException: Session is closed! at org.hibernate.impl.AbstractSessionImpl.errorIfClosed(AbstractSessionImpl.java:49) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:993) at org.jboss.seam.core.ManagedJbpmContext.beforeCompletion(ManagedJbpmContext.java:95) at org.jboss.tm.TransactionImpl.doBeforeCompletion(TransactionImpl.java:1491) at org.jboss.tm.TransactionImpl.beforePrepare(TransactionImpl.java:1110) at org.jboss.tm.TransactionImpl.commit(TransactionImpl.java:324) ... 39 more
Everything works fine if I deploy the process definition if I use this code instead:
String name=null;
JbpmContext jbpmContext=null;
String file = new String(workflow.getWorkflowFile());
ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(file);
JbpmConfiguration jbpmConf = JbpmConfiguration.getInstance();
jbpmContext = jbpmConf.createJbpmContext();
try {
jbpmContext.deployProcessDefinition(processDefinition);
} finally {
jbpmContext.close();
}
I'd rather use the Seam components. I've been loonking for some similar problems in the forum and I don't know if it is the same problem as in http://jira.jboss.org/jira/browse/JBSEAM-798. If only anyone could help me!
