There are non-Orthodox synagogues that are willing to perform homosexual ceremonies, but that is not the stance of classical Judaism, which does not condone homosexuality as a legitimate alternative lifestyle. Therefore, my answer would be as follows: Jewish tradition is strongly opposed to the very notion of "homosexual marriage" but there are plenty of contemporary rabbis who disagree with the traditional view. It's merely part of the traditionalist versus progressivist battle that is taking place within both Judaism and Christianity.
