Dear Mr. Tilman Hausherr, Please kindly accept my deep apology. And I cordially thank your quick and excellent, delightful answer. So far, I analyzed only the link to stackoverflow but will check all the link suggested by you. My major is not related to software but just bio-chemistry and I'm finalizing the development of my application these days. Therefore, I must take care of from A to Z, a millions of matters....I've been really hectic. Please kindly understand. While I didn't fully check all the link from you, but it doesn't make sense I need all the many dll files to only extract text from PDF. (But I'm really satisfied with the quality of PDFBox) Hope you can also develop a 'nitro turbo' button as a library(.dll)
Again, my deepest appreciation to you. All the best !
