再集成的时候有个如下配置
<process-engine-context>
    <string name="spring.cfg" value="applicationContext-system.xml" />
</process-engine-context>

请问上面的这个配置有什么用，我去掉后做了很多测试没有影响啊。那个value值我也改了，改成根本不存在的也没有什么影响，这是怎么回事呢？

没啥用，只有在spring没启动，先启动jbpm4的情况下，才会有用。

这是applicationContext.xml文件的配置：

 这是spring-jbpm4.cfg.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<jbpm-configuration>
	<process-engine-context>
    	<string name="spring.cfg" value="spring-jbpm4.xml" />
  	</process-engine-context>
	<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" />
	-->
</jbpm-configuration>

 

 

 按照这样的配置一定能搞定！

 

 

我在jpdl.xml中调用了一个类，写法如下：
   <task form="manager.html" g="172,225,92,52"  name="经理审批">
     <assignment-handler class="com.zwl.action.JointlySignAction">
       <field name="participants">
         <list>
         <string value="#{manager}"/>
         </list>
       </field>
     </assignment-handler>

类文件：
package com.zwl.action;

import java.util.List;

import org.jbpm.api.Configuration;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.TaskService;
import org.jbpm.api.model.OpenExecution;
import org.jbpm.api.task.Assignable;
import org.jbpm.api.task.AssignmentHandler;
import org.jbpm.api.task.Participation;
import org.jbpm.api.task.Task;
import org.jbpm.pvm.internal.task.OpenTask;


public class JointlySignAction  implements
AssignmentHandler {

/**
*
*/
private static final long serialVersionUID = 1L;


private ProcessEngine processEngine = Configuration.getProcessEngine();
//    private RepositoryService repositoryService;
//    private ExecutionService executionService;
private TaskService taskService = processEngine.getTaskService();
private List<String> participants;


@Override
public void assign(Assignable assignable, OpenExecution execution) throws Exception {
// TODO Auto-generated method stub
// String pid = execution.getProcessInstance().getId();
// Task task = taskService.createTaskQuery().processInstanceId(pid).
// activityName(execution.getName()).uniqueResult();
// createSubTasks(task);
return;
}

// public void createSubTasks(Task task) {
// if(participants != null) {
// for(String participant : participants) {
// Task subTask = ((OpenTask)task).createSubTask();
// subTask.setAssignee(participant);
// taskService.addTaskParticipatingUser(task.getId(), participant, Participation.CLIENT);
// }
// }
// }

public void setProcessEngine(ProcessEngine processEngine) {
this.processEngine = processEngine;
}


}

然后，每次调用这个类的时候，都会报classpath下无法找到spring-jbpm4.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<jbpm-configuration>
<process-engine-context>
    <string name="spring.cfg" value="spring-jbpm4.xml" />
  </process-engine-context>
<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" />
-->
</jbpm-configuration>

求教啊！

请问一下，事务你们是怎么配置的。
