jBPM载入定义的流程的方法

ProcessDefinition processDefinition = ProcessDefinition
    .parseXMLString("<process-definition>" + "  <start-state>"
      + "    <transition to='s' />" + "  </start-state>"
      + "  <state name='s'>" + "    <transition to='end' />"
      + "  </state>" + "  <end-state name='end' />"
      + "</process-definition>");

File zipFile = new File("./Flows/MyTest_1.zip");
  FileInputStream fIn = new FileInputStream(zipFile);
  ZipInputStream zipIn = new ZipInputStream(fIn);
  ProcessDefinition processDefinition = ProcessDefinition
    .parseParZipInputStream(zipIn);
