jBPM-jPDL学习笔记——流程设计与控制

想问一下 simple.jpdl 这个文件是在哪里的啊，我找不到这个文件，而且我只要 test connection 的时候就报错了，好象是连不上服务器。

原来博主就是林信良啊
汗，我还早就收藏了这个blog呢，居然现在才知道

按林兄写的代码测试，已经在数据库部署成功，但第一个4000元测试就过不去了，林兄能麻烦你看下是什么问题造成异常吗？是在'com.firstflow.task.NewApplicationAssignmentHandler' 出现问题的

从提示上看就是执行你的任务分配handler时出错了。看不出其他的，你应该在NewApplicationAssignmentHandler类中加一些跟踪代码调试一下

能帮我看一下这是什么错吗，谢谢了
Exception in thread "main" 00:00:21,171 [main] DEBUG JbpmContext : closing jbpmContext org.jbpm.JbpmContext@e48e1b
00:00:21,171 [main] DEBUG Services : closing service 'persistence': org.jbpm.persistence.db.DbPersistenceService@17f11fb
org.hibernate.HibernateException: Errors in named queries: GraphSession.findTokensForProcessInNode
at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:341)

执行查询时是这个错
org.hibernate.hql.ast.QuerySyntaxException: Invalid path: 'node.name' [
   
      select token
      from org.jbpm.graph.exe.Token token
      where token.processInstance.processDefinition.name = :processDefinitionName
        and node.name = :nodeName
   
  ]

我看了一下在org.jbpm.db中hibernate.queries.hbm.xml中有这样一个查询
<query name="GraphSession.findTokensForProcessInNode">
    <![CDATA[
      select token
      from org.jbpm.graph.exe.Token token
      where token.processInstance.processDefinition.name = :processDefinitionName
        and node.name = :nodeName
    ]]>
  </query>
也不明白这个查询是做什么用的，直接删除了，部署成功,可在执行代码时出现

楼主能看一下是什么问题吗

我觉得还是没有部署成功的问题，我在下载的文件中没有发现web.xml,于是新建了一个web.xml在webapp/WEB-INF/web.xml，然后把
<web-app>
<servlet>
  <servlet-name>GDP Deployer Servlet</servlet-name>
  <servlet-class>org.jbpm.web.ProcessUploadServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
  </servlet>
 
<servlet-mapping>
  <servlet-name>GDP Deployer Servlet</servlet-name>
  <url-pattern>/upload/*</url-pattern>
  </servlet-mapping>
 
</web-app>
加入到web.xml中，这样做不知道有没有问题
然后在流程设计器界面的“deployment”标签页中操作：
点击Test Connection会出这样的错
An exception happened while testing the server connection.
Resaon:
An unexcepted exception caused the test connection operation to fail
不明白是怎么回事，我初学java还望指点一下

楼上的兄弟，不要随便删除hibernate.queries.hbm.xml中的sql，有些是目前没有用的，但是为了后期jBPM的扩展，有用的。

看了你的异常，很多是数据库的session被关闭的原因。查查代码吧，有没有在关闭session后又对数据库进行操作的。

至于servlet部署异常，这个比较奇怪，不过尽量不要用“GDP Deployer Servlet”这种带空格的名字，我自己没有试过这个行不行，但最好不要吧。

这个servlet没有必要<load-on-startup>1</load-on-startup> 的。

org.jbpm.JbpmException: task node does not have leaving transition '主管同意'

查询这个错误时找到这里，看到很多人都有这个错误，原因大侠们说的也很一致，就是流程定义文件中transition name＝"主管同意"找不到。

但是问题是我的流程定义文件里有transition name＝"主管同意"这个东西呀？？？

十分迷惑……
下附流程定义文件的这一部分的定义：

   <task-node name="部门主管审核">
      <task name="主管审核">
         <controller>
            <variable name="baixiaoId" access="read" mapped-name="报销ID"></variable>
         </controller>
         <assignment class="org.springmodules.workflow.jbpm31.JbpmHandlerProxy" config-type="bean">
            <targetBean>managerAssignment</targetBean>
            <factoryKey>jbpmConfiguration</factoryKey>
         </assignment>
      </task>
      <transition name="要求修改" to="申请人修改报销单"></transition>
      <transition name="主管同意" to="判断走向"></transition>
   </task-node>

调试时是执行到以下代码报错的：
TaskInstance ti=jbpmContext.getTaskMgmtSession().getTaskInstance(Long.parseLong(tid));
if(result.equals("主管同意")||result.equals("主管不同意"))
{
ti.end("主管同意");
}
这一句ti.end("主管同意");完事就跳到catch块去了。
不知道怎么回事。楼主可以帮忙解答一下吗，不胜感谢！
