Failed to execute Kettle job file by java

Question

It's my first time to deal with Pentaho Data Integration, so i'm trying to execute the job from the java, but i failed to to this ! although of the job is working good from Spoon .

this is my code:

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

and this is the result which has an error !:

so any suggestions please ?

Thank you,

Once have a look at the code pasted below and it worked. You need to add all the Jars present in the data-integration/lib to the classpath not only the ones you have mentioned above.

   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!”);
 } }
  }
