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;

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.getDriverProperties().put( user,root );

ds1.init();
ut.begin();

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 22！！);
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();
}

To view the discussion, visit: http://community.jboss.org/message/613609#613609 -- The key point for the session to know about when a task is completed is the CommandBasedWSHumanTaskHandler in this case. If you're using the Mina based human task service your session must be up and your handler connected to be notified that a task was completed. There is a jms based human task service and handler that can help you to keep this service independent from the session. -- Reply to this message by going to Community [http://community.jboss.org/message/613609#613609] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1containerType=14container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
