Question

这是我第一次处理Pentaho数据集成，所以我正在尝试从java执行这项工作，但我未能做到这一点！虽然这项工作从Spoon开始运作良好。

这是我的代码：

jobMeta = new JobMeta(LogWriter.getInstance(), "E:\\rubbish\\job.kjb", null);
Job job = new Job(LogWriter.getInstance(), null , jobMeta);
job.start();
job.waitUntilFinished();

这是一个错误的结果！：

我正在使用这些罐子：

釜芯3.2.2.jar
釜-DB-3.2.2.jar
釜发动机3.2.2.jar

所以有什么建议吗？

谢谢，

一看下面粘贴的代码就可以了。 您需要将data-integration / lib中存在的所有Jars添加到类路径中，而不仅仅是您上面提到的那些。

   public class ExecuteJob {
   public static void main(String[] args) throws Exception {
  String filename = args[0];
  KettleEnvironment.init();
  JobMeta jobMeta = new JobMeta(filename, null);
  Job job = new Job(null, jobMeta);
  job.start();
  job.waitUntilFinished();
  if (job.getErrors()!=0) {
    System.out.println(“Error encountered!”);
 } }
  }

无法通过java执行Kettle作业文件
