jbpm 创建流程实例时 org.jbpm.scheduler.exe.Timer is not mapped.java.lang.IndexOutOfBoun

[牛肉干]

项目中的代码是：
public JbpmContext getJbpmContext() {
JbpmConfiguration config = JbpmConfiguration.getInstance();
JbpmContext jc = config.getCurrentJbpmContext() ;
if(jc == null){
jc = config.createJbpmContext() ;
}
return jc ;
}

/**
* 开始一个流程
*/
public void newProcessInstance(String issueperson,String wzId , String approvePersonId){
JbpmContext jc = getJbpmContext() ;
try {
jc.setActorId(issueperson) ;
ProcessDefinition pd = jc.getGraphSession().findLatestProcessDefinition("zwTest") ;
ProcessInstance pi = pd.createProcessInstance() ;
ContextInstance ci = pi.getContextInstance() ;
ci.setVariable("issue_person", issueperson) ;
ci.setVariable( APPROVE_ONE_PERSON , approvePersonId) ;
ci.setVariable( "wzId" , wzId) ;
TaskInstance ti = pi.getTaskMgmtInstance().createStartTaskInstance() ;
ti.setVariable("wzId", wzId) ;
ti.end() ;
} catch (Exception e) {
e.printStackTrace() ;
} finally{
if(jc != null){jc.close() ;}
}

}

执行到ProcessDefinition pd = jc.getGraphSession().findLatestProcessDefinition("zwTest") ;
得时候报出：

我部署的是jbpm3.2.2；ssh框架；在启动的时候报19:38:28,718 [main] ERROR SessionFactoryImpl : Error in named query: GraphSession.deleteJobsForProcessInstance
org.hibernate.QueryException: query must begin with SELECT or FROM: delete [

delete from org.jbpm.job.Job job
where job.processInstance = :processInstance

]
19:38:28,765 [main] ERROR SessionFactoryImpl : Error in named query: JobSession.deleteTimersForProcessInstance
org.hibernate.QueryException: query must begin with SELECT or FROM: delete [

delete from org.jbpm.job.Timer timer
where timer.processInstance = :processInstance

]的错误。这个是怎么回事啊？

有出问题了~~迷糊！！
我想问下：在根据用户名得到tasklInstance的时候出现13:40:00,046 [http-8082-3] ERROR JDBCExceptionReporter : ORA-00904: "TRUE": 无效的标识符

13:40:00,046 [http-8082-3] ERROR TaskMgmtSession : org.hibernate.exception.SQLGrammarException: could not execute query
org.jbpm.JbpmException: couldn't get task instances list for actor '301'
这个是为什么？
public List getTaskList(String userId){
List taskList = new ArrayList() ;
JbpmContext jc = getJbpmContext() ;
try {
taskList = jc.getTaskList( userId ) ;
} catch (Exception e) {
e.printStackTrace() ;
}finally{
if(jc != null){jc.close() ;}
}
return taskList ;
}这个是我调用的方法。我用的是SSH框架。
在线等待回答！~

你现在还在线吗？

在~这个问题我解决了~还是query.factory_class.xml得问题，可能是我spring其中解析hibernate的类不支持那种HQL的写法。

[牛肉干]

自己结贴吧！~这个问题已经解决了~
原因是org.jbpm.db.hibernate.query.factory_class.xml里面的语句有问题，delete from org.jbpm.job.Job job 应该改成delete from org.jbpm.job.Job as job 。这个原因可能是和spring对语句执行时监察出不规范的写法。还有一个是'node.name'的错误，是因为没有这个别名的原因。
这个可能和你的SPRING版本有关系。
呵呵~如果我没有描述详细的话，可以加我QQ724247860进行询问。或给我发邮件[e-mail]
