For Tootired2care and Garyneal: in the early Christian Church at the time the letters of James and Paul were written there were two churches in fact, one was the Judaic which continued with the traditions of Judaism and differed from other Jews only in that it had accepted Jesus as the Messiah (of the Jews) and Pauline or gentile Christianity that had rejected the Mosaic law and moved beyond it.
So you must have in mind that James wrote as a Judaic christian and follower of the Mosaic Law while Paul had moved beyond the Mosaic Law. Though the two churches came to an agreement to respect each other's approach as valid they never saw eye to eye and eventually the Judaic church disappeared.
The JWs being a strongly judaising religion would inevitably focus on the legalistic letter of James and ignore or minimise the ideas presented by Paul who had a far more flexible approach but never went as far as saying that just believing is enough and corresponding works were totally redundant as if one could do all sorts of bad things and then say: I believe in Jesus and so I will nonetheless be saved.
