kettle从XML文件加载转换[null]

Question

我准备使用kettle api动态执行一个作业。在这个过程中，我需要从XML文件加载转换。 问题：从XML文件加载转换[null]

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();

感谢

这一行

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

很可能意味着＆＃34; 在启动jvm的目录中传输transData.ktr ＆＃34;。至少尝试绝对文件路径。
