  Context. The Sun is an active star that produces large-scale energetic events
such as solar flares and coronal mass ejections and numerous smaller-scale
events such as solar jets. These events are often associated with accelerated
particles that can cause emission at radio wavelengths. The reconfiguration of
the solar magnetic field in the corona is believed to be the cause of the
majority of solar energetic events and accelerated particles. Aims. Here, we
investigate a bright J-burst that was associated with a solar jet and the
possible emission mechanism causing these two phenomena. Methods. We used data
from the Solar Dynamics Observatory (SDO) to observe a solar jet, and radio
data from the Low Frequency Array (LOFAR) and the Nan\c{c}ay Radioheliograph
(NRH) to observe a J-burst over a broad frequency range (33-173 MHz) on 9 July
2013 at ~11:06 UT. Results. The J-burst showed fundamental and harmonic
components and it was associated with a solar jet observed at extreme
ultraviolet wavelengths with SDO. The solar jet occurred at a time and location
coincident with the radio burst, in the northern hemisphere, and not inside a
group of complex active regions in the southern hemisphere. The jet occurred in
the negative polarity region of an area of bipolar plage. Newly emerged
positive flux in this region appeared to be the trigger of the jet.
Conclusions. Magnetic reconnection between the overlying coronal field lines
and the newly emerged positive field lines is most likely the cause of the
solar jet. Radio imaging provides a clear association between the jet and the
J-burst which shows the path of the accelerated electrons.
