jdpm的发布问题

由于是初学jdpm，出现的错误总摸不着头脑，我已经使用jdpm创建了数据库表，可是发布流程时出现以下错误：

解决方案 »

  1.   

    jbpm高手应该很快就能解决啊，高手们呢？？
      

  2.   

    错误的意思是xml写错了，你是用eclipse生成的不、
      

  3.   

    今天下午，我将ProcessDefinition.parseXmlResource("process.xml")改为ProcessDefinition.parseXmlString("xml的文件字符串")后能够执行，可是定义好流程之后，我们一般都是读取xml而不去读取字符串啊，怎么解决这个parseXmlResource()方法的错误呢？
      

  4.   

    问题解决：process.xml路径错误，应该放在src目录下，而不是跟JbpmTest02_Deploy 同目录下
