The reason I asked is because during His ministry, the family of the Lord (except His Mother) were not followers of Him. It was only after Jesus appeared to James that he believed. He was the leader of the Church in Jerusalem for 19 years and remained a devout Jew. James was martyred because he would not recant having seen the Lord after the crucifixion.
Of course you are right that traditionally the Epistle of James is attributed to James the Just, not James the son of Zebedee or James the son of Alphaeus. (The writer of the epistle simply calls himself James, with no other identification.) My mistake.
Whoever wrote it, I see nothing wrong with the Epistle of James.
