kettle从XML文件加载转换[null]

Question

我已经准备好使用kettle api来执行作业dynamically.In的过程，我需要加载转换从XML文件。问题:从XML文件加载转换为空

代码：

KettleEnvironment.init();
JobMeta jobMeta = new JobMeta();
jobMeta.setName("jobMeta");
int x=50,y =50;

JobEntryCopy startCopy = JobMeta.createStartEntry();
startCopy.setLocation(x, y);
startCopy.setDrawn();
jobMeta.addJobEntry(startCopy);
JobEntryCopy lastCopy = startCopy;

JobEntryTrans jobEntryTrans = new JobEntryTrans("transData.ktr");


jobEntryTrans.setSpecificationMethod(
    ObjectLocationSpecificationMethod.FILENAME);
JobEntryCopy transCopy = new JobEntryCopy(jobEntryTrans);
transCopy.setName("Execute" + GlobalMethodAndParams.TRANS_NAME);
transCopy.setDrawn();
jobMeta.addJobEntry(transCopy);
JobHopMeta transHop = new JobHopMeta(lastCopy,transCopy);
jobMeta.addJobHop(transHop);
lastCopy = transCopy;

Job job = new Job(null,jobMeta);
job.start();
job.waitUntilFinished();

谢谢

这一行

JobEntryTrans jobEntryTrans = new JobEntryTrans("transData.ktr");

最可能的意思是“jvm启动目录中的文件transData.ktr ”。至少尝试绝对文件路径。
