Here's a statement evaluating Martin Luther's opinion of the Epistle of James.
Luther strongly repudiated the Epistle as "a letter of straw", and "unworthy of the apostolic Spirit", and this solely for dogmatic reasons, and owing to his preconceived notions, for the epistle refutes his heretical doctrine that Faith alone is necessary for salvation.
Soley for dogmatic reasons? As I've looked at this over the years, it's more complicated than that. There's actually contradicting evidence on Luther's opinion of the Epistle of James and exactly what his "rejection" entirely entails. Let's take a look at these charges and see if the real reason (or reasons) Luther rejected James can be determined.

I came by the statement above on a website dedicated to early Christian writings. Searching for the author, the webpage cited: "Camerlynck, A. "Epistle of James." Early Christian Writings. 2023. 22 Jan. 2023." Doing a search for "Camerlynck, A," I discovered this webpage was a complete cut-and paste from the old Catholic Encyclopedia. Achilles Camerlynck was a well-educated Roman Catholic scholar from long ago. The old Catholic Encyclopedia is generally not favorable to Luther, so it makes sense that multiple shots are taken at Luther by Camerlynck.
The early Christian Writings website appears to be selling CD-ROM's (remember those?) of the entire content of the website (I'm not sure what the legality of that is... selling someone else's work?). Back in 2015, the owner of the site gave a brief overview of who he was: a young man with Roman Catholic roots that's become some sort of agnostic (as of 2015). Where he is now on his spiritual journey, I didn't spend time to discover. His blog entries stop December 2015. From a cursory search, he appears to have fallen off the cyber-radar in 2015.
Letter of Straw? Epistle of Straw?
Luther's famous statement is "Saint James’ epistle is really an epistle of straw" compared to John's gospel and epistles, Paul's epistles, and 1 Peter, and, further, that James "has nothing of the nature of the gospel about it" (LW 35:362). The "epistle of straw" line comes from Luther's Preface to the New Testament, originally penned in 1522. I suspect most realize this is a negative comment.
Divergences from the original 1522 text were due primarily to Luther’s desire to accommodate the text of the New Testament prefaces to that of the Old Testament prefaces with which they were—in the 1534 complete Bible—to appear for the first time, rather than to criticism on the part of Emser or other opponents (LW 35:357, fn 5).
106 Many, with much probability, have asserted that this epistle was not written by the apostle James, and that it is not worthy of an apostolic spirit (Luther) .
For Luther seemed to the best people to have proceeded too maliciously against the Sacred Scripture of the New Testament; since he had, with an audacious censorship, rejected the Letter to the Hebrews, the Letter of James, the Letter of Jude, and the Apocalypse of John from the canon of the New Testament. He defamed these books openly, with savage falsehoods, in his prefaces.
If ever folly has been uttered, it has been uttered especially on this subject: I will say nothing of the fact that many assert with much probability that this epistle is not by James the apostle, and that it is not worthy of an apostolic spirit; although, whoever was its author, it has come to be regarded as authoritative. But even if the apostle James did write it, I still would say, that no apostle has the right on his own authority to institute a sacrament, that is, to give a divine promise with a sign attached. For this belongs to Christ alone (LW 36:118).
A blatant thing to note here is that there's nothing in the context about faith alone. Luther is expressing doubts about the authorship of James in regard to extreme unction. Here Luther presents two options but appears to favor the Epistle of James as not apostolic, though grants the possibility of it being apostolic. For Luther, the epistle of James may have been written by a later Christian, therefore not an apostle or eyewitness of the risen Christ, therefore not canonical.
Just a year earlier (1519), Luther wrote the following, (and this may be his earliest criticism of James):
For although it is argued from the epistle of the Apostle James that ‘faith without works is dead,’ the style of that epistle is far inferior to the Apostolic majesty of St. Paul, and should in no way be compared with him. Paul speaks of living faith, for a faith that is dead is not faith but opinion. Yet you see theologians who hold on to this one authority and care nothing at all that the rest of Scripture teaches faith without works. That’s how these fellows do it. They rip out one little phrase from a text and set it up against all of Scripture. [Quod autem Iacobi Apostoli epistola inducitur ‘Fides sine operibus mortua est’, primum stilus epistolae illius longe est infra Apostolicam maiestatem nec cum Paulino ullo modo comparandus, deinde de fide viva loquitur Paulus. Nam fides mortua non est fides, sed opinio. At vide theologos, hanc unam autoritatem mordicus tenent, nihil prorsus curantes, quod tota alia scriptura fidem sine operibus commendet: hic enim mos eorum est, una abrepta oratiuncula textus contra totam scripturam cornua erigere] (WA 2:425; English translation).
...[H]e throws things together so chaotically that it seems to me he must have been some good, pious man, who took a few sayings from the disciples of the apostles and thus tossed them off on paper. Or it may perhaps have been written by someone on the basis of his preaching [LW 35: 396-397].
Moreover he cites the sayings of St. Peter [in 5:20]: “Love covers a multitude of sins” [1 Pet. 4:8], and again [in 4:10], “Humble yourselves under the hand of God” [1 Pet. 5:6]; also the saying of St. Paul in Galatians 5[:17], “The Spirit lusteth against envy.” And yet, in point of time, St. James was put to death by Herod [Acts 12:2] in Jerusalem, before St. Peter. So it seems that [this author] came long after St. Peter and St. Paul [LW 35:397].
When challenged that the Epistle of James stood against justification by faith alone, in 1543 Luther stated: "The authority of this (James) is not so great that (it detracts from the divine promise [or that] on its account one should abandon the doctrine of faith and depart from the authority of the rest of the apostles and all of Scripture" [LW 73:349-350; WA 39(2): 219].
Luther is recorded in a 1542 Table Talk utterance saying,
We should throw the Epistle of James out of this school, for it doesn’t amount to much. It contains not a syllable about Christ. Not once does it mention Christ, except at the beginning [Jas. 1:1; 2:1]. I maintain that some Jew wrote it who probably heard about Christian people but never encountered any. Since he heard that Christians place great weight on faith in Christ, he thought, ‘Wait a moment! I’ll oppose them and urge works alone.' This he did. He wrote not a word about the suffering and resurrection of Christ, although this is what all the apostles preached about. Besides, there’s no order or method in the epistle. Now he discusses clothing and then he writes about wrath and is constantly shifting from one to the other. He presents a comparison: ‘As the body apart from the spirit is dead, so faith apart from works is dead’ [Jas. 2:26]. O Mary, mother of God! What a terrible comparison that is! James compares faith with the body when he should rather have compared faith with the soul! The ancients recognized this, too, and therefore they didn’t acknowledge this letter as one of the catholic epistles.” [LW 54:424].I say "recorded in the Table Talk" because Luther didn't write these words, someone else transcribed them, context unknown. The comments do though match up to the sentiment found in Luther's earlier comments.
It is possible that the position of Erasmus had influenced Luther in some particulars. Luther had first expressed his critical attitude towards the Epistle of St. James in his Resolutiones of 1519; afterwards more energetically in De Captivitate Babylonica. Under such conditions we have no reason to be surprised that Luther entered into the question in his New Testament of 1522, especially as the fundamental understanding of Scripture that had come to him compelled him to take a stand, at least concerning James, and furthermore, he did not think that these matters were to be kept hidden from the congregations but even discussed them in his sermons [M. Reu, Luther’s German Bible: An Historical Presentation Together with a collection of Sources (Ohio: The Lutheran Book Concern, 1934), 176].
In fine, he wanted to guard against those who tried to rely on faith without works but he was too weak in spirit, understanding and words, and so he rends Scripture and opposes Paul and all Scripture, trying to accomplish by the occasion of the Law what the other apostles effect by incentives to love. Therefore I will not have him reckoned in my Bible in the number of the real chief books, but will not prevent anyone from esteeming him as he pleases, for otherwise it contains many good sayings. One man is reckoned, as no man in worldly affairs. How then should this one alone count against Paul and all the rest of Scripture ?

For it contains many good sayings.Did Luther Want to Throw the Epistle of James in the Stove?
That epistle of James gives us much trouble, for the papists embrace it alone and leave out all the rest. Up to this point I have been accustomed just to deal with and interpret it according to the sense of the rest of Scriptures. For you will judge that none of it must be set forth contrary to manifest Holy Scripture. Accordingly, if they will not admit my interpretations, then I shall make rubble also of it. I almost feel like throwing Jimmy into the stove, as the priest in Kalenberg did [LW 34:318; cf WA 39(2):199, n.2].
The preacher of Kalenberg, when visited by the duchess, heated the room with the wooden statues of the apostles. The statue of James was the last and as the preacher shoved it into the stove he exclaimed, “Now bend over, Jimmy, you must go into the stove; no matter if you were the pope or all the bishops, the room must become warm" [LW 34:318].
Even though Luther isn't saying to throw the actual Epistle of James into the stove, it's obvious there's a sarcastic intent to his comment and frustration being expressed.
James is dealing with a moral point, not theological, just as he is almost entirely about morality. Morally speaking, it is true that faith without works is dead- that is, if faith does not do works or if outward works do not follow faith. In this way then, faith cannot exist apart from works; that is, it cannot fail to do works, else there is no faith alone.
We, however, are dealing with a theological point here since we are discussing justification before God. Here we assert that faith alone is counted as righteousness before God, apart from works and merits." (LW 61:183-184).
The argument is sophistical and the refutation is resolved grammatically. In the major premise, ‘faith’ ought to be placed with the word ‘justifies’ and the portion of the sentence ‘without works justifies’ is placed in a predicate periphrase and must refer to the word ‘justifies,’ not to ‘faith.’ In the minor premise, ‘without works’ is truly in the subject periphrase and refers to faith. We say that justification is effective without works, not that faith is without works. For that faith which lacks fruit is not an efficacious but a feigned faith. ‘Without works’ is ambiguous, then. For that reason this argument settles nothing. It is one thing that faith justifies without works; it is another thing that faith exists without works. [LW 34: 175-176].
See, this is what James means when he says, 2, 26: "Faith apart from works is dead." For as the body without the soul is dead, so is faith without works. Not that faith is in man and does not work, which is impossible. For faith is a living, active thing. But in order that men may not deceive themselves and think they have faith when they have not, they are to examine their works, whether they also love their neighbors and do good to them. If they do this, it is a sign that they have the true faith. If they do not do this, they only have the sound of faith, and it is with them as the one who sees himself in the glass and when he leaves it and sees himself no more, but sees other things, forgets the face in the glass, as James says in his first chapter, verses 23-24.
[This passage in James deceivers and blind masters have spun out so far, that they have demolished faith and established only works, as though righteousness and salvation did not rest on faith, but on our works. To this great darkness they afterwards added still more, and taught only good works which are no benefit to your neighbor, as fasting, repeating many prayers, observing festival days; not to eat meat, butter, eggs and milk; to build churches, cloisters, chapels, altars; to institute masses, vigils, hours; to wear gray, white and black clothes; to be spiritual; and innumerable things of the same kind, from which no man has any benefit or enjoyment; all which God condemns, and that justly. But St. James means that a Christian life is nothing but faith and love. Love is only being kind and useful to all men, to friends and enemies. And where faith is right, it also certainly loves, and does to another in love as Christ did to him in faith. Thus everyone should beware lest he has in his heart a dream and fancy instead of faith, and thus deceives himself. This he will not learn anywhere as well as in doing the works of love. As Christ also gives the same sign and says: "By this shall all men know that ye are my disciples, if ye have love one to another." John 13, 35. Therefore St. James means to say: Beware, if your life is not in the service of others, and you live for yourself, and care nothing for your neighbor, then your faith is certainly nothing; for it does not do what Christ has done for him. Yea, he does not believe that Christ has done good to him, or he would not omit to do good to his neighbor. [The Complete Sermons of Martin Luther Vol. 3:1 (Michigan: Baker Books, 2000), pp. 71-72].
This is what St. James means when his says in his Epistle, 2:26: ‘"Faith without works is dead." That is, as the works do not follow, it is a sure sign that there is no faith there; but only an empty thought and dream, which they falsely call faith. Now we understand the word of Christ: "Make to yourselves friends by means of the mammon of unrighteousness." That is, prove your faith publically by your outward gifts, by which you win friends, that the poor may be witnesses of your public work, that your faith is genuine. For mere external giving in itself can never make friends, unless it proceed from faith, as Christ rejects the alms of the Pharisees in Mat. 6:2, that they thereby make no friends because their heart is false. Thus no heart can ever be right without faith, so that even nature forces the confession that no work makes one good, but that the heart must first be good and upright. [The Complete Sermons of Martin Luther Vol. 2:2 (Michigan: Baker Books, 2000), p. 308].
In the earliest general history of the church, Eusebius: The Ecclesiastical History (II, xxiii, 25), the author… writes, “Such is the story of James, whose is said to be the first of the Epistles called Catholic. It is to be observed that its authenticity is denied, since few of the ancients quote it, as is also the case with the Epistle called Jude’s.”… Eusebius also includes both epistles in his list of “Disputed Books” (History, III, xxiv, 3)…Cf. the statement by Jerome (d. 420) in his Liber de Viris Illustribus (II) concerning the pseudonymity ascribed to the epistle of James and its rather gradual attainment of authoritative status [LW 35:396].
Follow this up the following from The New Catholic Encyclopedia:
According to Catholic doctrine, the proximate criterion of the Biblical canon is the infallible decision of the Church. This decision was not given until rather late in the history of the Church (at the Council of Trent). Before that time there was some doubt about the canonicity of certain Biblical books, i.e., about their belonging to the canon.

Addendum #2: John Warwick Montgomery
Here's nitpicking myself: Back in 2004, I addressed the "epistle of straw" comment in Luther's View of the Canon of Scripture. I cited John Warwick Montgomery writing,
Few people realize — and liberal Luther interpreters do not particularly advertise the fact — that in all the editions of Luther’s Bible translation after 1522 the—Reformer dropped the paragraphs at the end, of his general Preface to the New Testament which made value judgments among the various biblical books and which included the famous reference to James as an “Epistle of straw.In my old paper I summarized Motgomery saying, "An interesting fact about this quote (hardly ever mentioned by Luther-detractors!) is that it only appears in the original 1522 Preface To The New Testament." It is true that, as it was back in 2004, I did not come across Rome's defenders admitting Luther deleted the comment, "epistle of straw." On the other hand, LW 35:358, fn. 5 states: "The portions here set in brackets did not appear in any editions of the complete Bible, nor in editions of the New Testament after 1537." It appears to me that editions of Luther's New Testament previous to 1537 and incomplete editions of the Bible previous to 1534 probably did include the "epistle of straw" comment.
