Bryan Shaw [http://community.jboss.org/people/silverhoof] created the discussion "JBPM 4.4 and Spring Integration Problem: Session is closed" To view the discussion, visit: http://community.jboss.org/message/587042#587042 -------------------------------------------------------------- I have encountered problem when I am using JBPM 4.4 with Spring 3.5 and Hibernate 3 and Struts2. When we put multiple users to use the system, JBPM operation will randomly cause Hibernate Exception states: "Session is closed". I have checked the JBPM + Spring integration configuration and I can't found error. Did anybody encountered the same problem here? Please lend a hand to help me. This is my "jbpm.tx.spring.cfg.xml" * * <?xml version="1.0" encoding="UTF-8"?>      <jbpm-configuration spring="enabled">      <process-engine-context>             <command-service name="newTxRequiredCommandService">               <retry-interceptor />               <environment-interceptor policy="requiresNew" />               <spring-transaction-interceptor transaction-manager="transactionManager" policy="requiresNew" current="false"/>             </command-service>          <!-- Default command service has a Spring transaction interceptor-->          <command-service name="txRequiredCommandService">                 <retry-interceptor />                 <environment-interceptor />                 <spring-transaction-interceptor transaction-manager="transactionManager" current="true"/>          </command-service>     </process-engine-context>      <transaction-context>          <transaction type="spring" />          <hibernate-session current="true" close="false" tx="true"/>     </transaction-context> </jbpm-configuration> And my jbpm-cfg.xml looks like this: <?xml version="1.0" encoding="UTF-8"?> <jbpm-configuration>   <import resource="jbpm.default.cfg.xml" />   <import resource="jbpm.tx.spring.cfg.xml" />   <import resource="jbpm.jpdl.cfg.xml" />   <!--<import resource="jbpm.bpmn.cfg.xml" />-->   <import resource="jbpm.identity.cfg.xml" />   <import resource="jbpm.businesscalendar.cfg.xml" />   <import resource="jbpm.console.cfg.xml" />   <import resource="jbpm.jobexecutor.cfg.xml" />   <types resource="jbpm.variable.types.xml" /> </jbpm-configuration> We use OpenSessionInView filter in our web application that means every request will have its own hibernate session opened for it. But we find that even I begin a request handling action method with a call to the JBPM task service it still may cause session is closed error. Any idea? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/587042#587042] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
