application-data.xml
XML code
<bean id="dataSource" destroy-method="close" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.dirver}" />

jbpm.hibernate.cfg.xml中
XML code
   <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
     <property name="hibernate.connection.url">jdbc:mysql:///**</property>
     <property name="hibernate.connection.username">root</property>
     <property name="hibernate.connection.password">root</property>
     <property name="hibernate.format_sql">true</property>
     
     <mapping resource="jbpm.repository.hbm.xml" />
     <mapping resource="jbpm.execution.hbm.xml" />
     <mapping resource="jbpm.history.hbm.xml" />
     <mapping resource="jbpm.task.hbm.xml" />
     <mapping resource="jbpm.identity.hbm.xml" />
     


jbpm.cfg.xml中
XML code
  <import resource="jbpm.default.cfg.xml" />
  <import resource="jbpm.businesscalendar.cfg.xml" />
  <import resource="jbpm.tx.hibernate.cfg.xml" />
  <import resource="jbpm.jpdl.cfg.xml" />
  <import resource="jbpm.bpmn.cfg.xml" />
  <import resource="jbpm.identity.cfg.xml" />

  <import resource="jbpm.mail.templates.examples.xml" />
  
  <process-engine-context>
    <string name="spring.cfg" value="classpath:applicationContext-data.xml" />
  </process-engine-context>


问题：
1.application-data.xml 中的数据源 和jbpm.hibernate.cfg.xml中的数据源分别有什么用？jbpm.hibernate.cfg.xml不配置数据源会报错。
2.jbpm+s2sh的配置加载顺序是什么
3.只配置<bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper" />
  <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />
可以成功
加上
  <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
会报错。
