  Using the Very Large Array (VLA) in the A-configuration, we have obtained a
high-resolution 3.6 cm map of a hard X-ray source detected by the Chandra X-ray
Observatory in a protostellar clump in Orion molecular cloud 3. Two radio
continuum sources were detected in the vicinity of the X-ray source, both of
which have NIR counterparts. We conclude that these VLA sources are free-free
emission produced by shocks in protostellar jets from the NIR class I
protostars. Using the centimeter data, we determined the power and orientation
of the protostellar jets. The center position of the X-ray emission was found
to be ~1--2" offset from the exciting sources of the jets, and the displacement
is in the direction of the jets and molecular outflows. We discuss the nature
of the X-ray emission as the shock-excited plasma at the shock front where the
jet propagates through interstellar medium at a speed of ~1000 km/s.
