Hi Hui,
                 JobID constructor is not a public constructor it has default visibility so
you have to create the instance within the same package.
                 Usually you cannot create a JobID rather you can get one from the JOB instance
by invoking getJobID().
                 If this doesnot works for you, please tell what you are trying to do?

I call the sentence "JobID id = new JobID()" of hadoop API with JNI. But when my program run
to this sentence, it exits. And no errors output. I don't make any sense of this. 
The hadoop is hadoop-core-1.0.3.jar.
The Java sdk is jdk1.6.0-34.

Any help will be appreciated.
