Executing a PDI job

When we say execute a job we actually mean: "execute a job as described in the job metadata object".  So naturally we first need to load a JobMeta object from XML (with a JobMeta constructor as described below where repository can be null) or from a repository.

JobMeta jobMeta = new JobMeta("/foo/bar/job.kjb", repository);
Job job = new Job(repository, jobMeta);
job.start();
job.waitUntilFinished();
Result result = job.getResult();

The Result object will then contain all sorts of interesting results pertaining to the execution, including the number of errors, parsed files and much more as described over here.
