In the mid to late 90's, there was a magazine called the "Java Report", which was dedicated to all things Java. I was a semi regular columnist for that magazine. The magazine lasted a few years, eventually ceasing production in the late 90's.
Years later, a book title "Java Gems" was released, which contain chosen articles from the magazine.
