The production of forward jets of transverse energy E-T similar or equal to
Q and large momentum fraction x(jet) much greater than x is calculated in
next-to-leading order including consistently direct and resolved virtual ph
oton contributions. The predictions are compared to recent ZEUS and H1 data
. Good agreement with the data is found. (C) 1999 Published by Elsevier Sci
