Reshu,

UIMA-AS configurations are normally used in DUCC as Services for
interactive applications or to support Jobs. They can be used in Jobs, but
typically are not.

There is also a difference in the inputs between Job processes and
Services. Services will normally receive a CAS with the artifact to be
analyzed. A Job process will receive a CAS with reference to the artifact
or even collection of artifacts; this is important for Job scale out to
avoid making the Job's Collection Reader a bottleneck.

I suggest starting with one of the sample applications and adapting it to
your needs. We can help if you give some details about the format of the
input and output data.

Eddie
