Even though this API abstracts from the really low-level details, the interfaces are also considered somewhat low-level and the average application developer in Java EE is either assumed to be relying on transparent handling of transactions by the higher level EJB abstractions, or using the annotations provided by this API in combination with CDI managed beans.

You package everything in a single, executable JAR file, driven by a good old Java main method. Once upload is done go to the directory and check if the file is uploaded or not. File upload Example.
Angular 6 App Client — upload-file. See the other example s for uploading larger files. There has been a lot of discussion lately about WebSockets. For this I am using here pdfbox API. Note that sending large files over WebSocket by reading them into array buffers may not be the most optimum way to upload them as it can quickly occupy to much memory resulting in a poor experience.

So this unknown smart developer in Iran called Youness downloaded a copy of my book illegally because it was nearly impossible to get a hard copy posted to him.
He liked my book so much and felt so guilty that he decided to give me some feedback and corrections. So for weeks Youness sent me pages and pages of reviews. Hundreds of items, from small typos to technical thoughts. All in a table format in a very structured way with page number, problem encountered and possible correction.
I was amazed by this guy. Most of his comments were accurate. He had spent hours and hours reading every single page of my book, every code example, compiling it, analyzing it and giving me his opinion.
And here I am now, in writing a Java EE 7 book, the one you have in front of you legally I hope ;o. As usual I was late, I was begging APress to give me a few extra weeks, I was sleeping 4 hours per night, writing during days, nights and weekends… and still running late.
I only had two more chapters to go… and thought of multi-threading. Four years after our email exchanges, I remembered Youness. Thanks for helping me out Youness, thanks for taking the time to write most of the chapter.

I just want to thank the Internet for this magic communication channel it has become. So no matter how bad I think the Internet could go, I will always remember this virtual meeting I had with Youness four years ago.
Who is Youness? In which Google Circle should I add him? When my editor read this text, he just deleted it without informing me. Weeks later, when I was reviewing the final chapters, I noticed that a couple of pages were missing. I asked my editor what had happened and received the following : The main problem with the anecdote, though well-intentioned, was that it seemed to condone piracy which we spend a lot of money trying to combat.
I would never have thought that my Java book could be part of such censorship. History has shown that censorship is the best way to alienate people.
Piracy Another issue about this text was piracy. It is a very difficult topic. I am an author, I spent months of very hard work writing a book, taking literally months off work, with no incomes and putting myself into a difficult financial situation.
