"Re: How to reload knowledgeSession from database?" To view the discussion, visit: http://community.jboss.org/message/613608#613608 -------------------------------------------------------------- Thank you! I have tried this method, #but after the intercepted human task was completed, the Ksession couldn’t know it, the state of the task was still 1, and I couldn’t continue with the other tasks. How can I solve this problem? Here are codes: package com.sample; import java.util.HashMap; import java.util.Map; import java.util.Properties; import javax.naming.InitialContext; import javax.persistence.EntityManagerFactory; import javax.persistence.Persistence; import javax.transaction.UserTransaction; import org.drools.KnowledgeBaseFactory; import org.drools.base.MapGlobalResolver; import org.drools.runtime.*; import org.drools.persistence.jpa.*; import org.jbpm.process.audit.JPAWorkingMemoryDbLogger; import org.jbpm.process.workitem.wsht.CommandBasedWSHumanTaskHandler; import bitronix.tm.TransactionManagerServices; import bitronix.tm.resource.jdbc.PoolingDataSource; public class TestLoadSession { public void loadSession(){ EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" ); Environment env = KnowledgeBaseFactory.newEnvironment(); env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf); env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager()); env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() ); StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession( 1, KBaseFactory.getKbase(), null, env ); } public static final void main(String[] args) { try{ UserTransaction ut = (UserTransaction) new InitialContext().lookup( "java:comp/UserTransaction" ); PoolingDataSource ds1 = new PoolingDataSource(); ds1 = new PoolingDataSource(); ds1.setUniqueName( "jdbc/testDS1" ); ds1.setClassName( "com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" ); ds1.setMaxPoolSize( 3 ); ds1.setAllowLocalTransactions( true ); ds1.getDriverProperties().put( "user","root" ); ds1.getDriverProperties().put( "password","111111" ); ds1.getDriverProperties().put( "URL", "jdbc:mysql://localhost:3306/jbpm5db" ); ds1.init(); ut.begin(); EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" ); Environment env = KnowledgeBaseFactory.newEnvironment(); env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf); env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager()); env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() ); //Properties properties = new Properties(); //properties.put("drools.processInstanceManagerFactory", "org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory"); //properties.put("drools.processSignalManagerFactory", "org.jbpm.persistence.processinstance.JPASignalManagerFactory"); //KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties); StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession( 1, KBaseFactory.getKbase(), null, env ); ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new CommandBasedWSHumanTaskHandler(ksession)); JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(ksession); //ksession.notifyAll(); //ksession.abortProcessInstance(1); //ksession.startProcessInstance(1); //ksession.getProcessInstance(1). ut.commit(); logger.dispose(); ut.begin(); Map data2=new HashMap(); Map data3=new HashMap(); data3.put("name", "This is my test Human Task param 222222！！"); data3.put("second", "The Second is KYO！！"); data2.put("name1",data3); System.out.println("This is before commit："+data2); JbpmAPIUtil.completeTask(1, data2, "krisv"); ut.commit(); System.out.println("LOADSSESSION success!"); } catch(Exception e){ e.printStackTrace(); } } } -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/613608#613608] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
