 Dear HP & windows 10 user community, I hope this might help you bypass the vicious circle of windows 10 or even 11, never ending preparing automatic repair process. My current laptop model is HP Pavilion Power - 15-cb007nv, which I used to teach & present IT lessons. One cannot image how much time I have spent in setting up the development environments, servers, database, middle

This new post will offer some solutions for users testing their simple, non database driven, PHP web application on the standalone internal PHP server of Netbeans IDE 12. If one does not want to start the Apache server within xampp, ampp,lamp or whatever distribution one likes, the PHP internal web server option during the project creation screens of Netbeans will do the job.However, the page

This new post concerns only greek speaking people, willing to study IT in Athens, at the vocational school of the hellenic handycrafts society. Therefore the invitation text will be only in Greek!

Did you notice the strange circular arc stand? This new post describes my experiences regarding the use of the 43 inch  LG 43UK6400PLF Ultra High Definition 4k, following the review path of the 32LF650V smart tv. More or less the contents of the other post concerning the LG 32 LB650 still apply, but there are some more or less stale news as well. On the bright side, the PMI refresh rate

As the title says the authors emphasizes on proprietary open source technologies based on Spring Boot and Java 1.8. The  huge text assumes an advanced reader who  not only has solid experience in several Cloud computing  vendors, namely Amazon web services,   but also in Spring, REST web services, integration and design architecture. This is clearly not a book for

On the bright side the book is well organized, written in American English and presents a neat introduction to the three most popular cloud providers Amazon Web Services, Azure and Google Cloud. Although Heroku is not presented, but only mentioned once,  neither IBM nor Oracle cloud is even mentioned at all, as if they did not exist... Rainy days for both Oracle cloud and IBM? I only hope

This new post addresses another repetitive task which draws the attention of a Java developer, as the time goes by and newer versions of the jdk become available for the public. That is updating the Netbeans IDE with the most current version by editing the file:  "C:\PathtoProgramFiles\NetBeans 8.1\etc\netbeans.conf" Although the IDE is smart enough to locate an existing jdk, every

More or less the contents of the other post concerning the LG 32 LB 650 still apply, but there are some news as well. On the bright side, the refresh rate has been increased to 900 Hz offering a clearer high definition view then the predecessor, especially during satellite reception.  The

The specific model at hand is 32LB650, which comes with WebOS and also provides a satellite receiver.

In case you could not wait to migrate your last project to the currently newer version of JDeveloper 12c, you might have been disappointed with several recurring  errors, or an entire EJB 3 application not running at all. Familiar or not? In this new post a solution for returning to the older version will be presented, for those who receive an error message that the workspace cannot

Image may differ! On the bright side, the text is of very good quality with only few spelling errors, accurate definitions and plenty of examples. The most important advantage of the book is that it offers a plethora of exercises both for the beginner and the advanced student. Its colourful design offers an image, which is very pleasant to the reader's eyes. A separate key to the exercises,

HP keys can be faulty I have used a minimum of three HP laptops, two of them Pavilions, still working. The older one running Windows xp flawlessly, came with many CD's such as drivers, including two CD's with versions of Windows in different languages. On the other hand, the newer one has been rather a disappointment! Starting from unpacking I found out the printed configuration label

  Following the trend of discovering ancient Greece is a new exhibition in Frankfurt am Main. More details one can find here: http://kulturfonds-frm.de/projekte/zurueck-zur-klassik-ein-neuer-blick-auf-das-alte-griechenland One step further for those who have been taught some form of Greek at school, is visiting the available online museums of Greece and reading the literature

On the bright side, the text is of average quality written in American English. It is well organized, full of  helpful images though of the older JDeveloper 11.1.1.5 version, with minimal if any tutorials or hands on practice. The author explains clearly some points, such as  the different kinds of BPEL processes, synchronous, asynchronous, one way or bilateral, especially in the

In this post an alternative code version to the traditional ImageServlet  will be given, supplementing the one presented in the book named Oracle Fusion Developer Guide (p.409), by F.Nimphius and L.Munsinger and other official Oracle aces' and employees' blogs. This alternative version will use the  EJB 3 way to get rid of the surplus database definition hard coded in the doGet() method

Following the articles by J.Stegeman and E.Biemond about building via ant scripts,  external to JDeveloper, one can quickly find out that the former does show how to create a war file, out of mostly .xml files, but not an ear; and the latter  misses on creating a war file out of the ViewController project! This article comes as supplement of both, showing how to jar the ejb3 model

Searching for selectManyChoice  in the J2EE or fusion  11g developer guides does not return more than a series of drag and drop instructions. Again, the programmer is left at one's own devises, to improvise in order to find the solution. This is no exception to the rule that when in need or emergency, the only thing one is certain to find in a technical guide document is missing

Apart from setting up a domain with the jrf libraries and data sources, presently the books and developer guides for  ADF 11g development do not delve into deployment troubleshooting details, as the prior ADF 10g documentation did. Moreover, the older docs included deployment directions for Tomcat, JBoss, etc, which is currently missing from the 11g versions. This rough guide is a supplement

This new post is an exception to the rule of commenting on  books I have read, or better studied even their code. Since the author is an old colleague and a friend of mine who has helped me in the past, I feel obliged to present his new book, which is currently in preparation. I am afraid I have not studied the whole text, the complete source code is though available; just read some parts of

On the bright side the text is well written in American English. It is well organized, full of  helpful images of the older JDeveloper 11.1.1.2 version, tutorials and hands on practice. The setup instructions are accurate, detailed and the full source code is available online too.  On the dark side, the text is full of marketing lecture, whole chapters of promoting the suite, using

On the bright side, the text is very well written without spelling errors. The author has organized each sequence of paragraphs so well, as neat as a chain having rings following  one chapter after another.  There are plenty of metaphors, analogies and examples from the daily life to help the reader grasp the Spring fundamentals. On the dark side, the book has no tutorial format; in

On the bright side the cook book is well written, in American English, with some spelling errors.The error page of the book presents at the moment only unconfirmed errata: http://oreilly.com/catalog/errataunconfirmed.csp?isbn=9780596520731 The book consists of a series of  useful stand alone ...dishes; articles structured like this: specific problem, relevant solution, discussion of java

In this new article we shall discuss about implementing the model layer for a simple REST style web service, presented in a book authored by Eben Hewitt, called SOA Cookbook.  In example 8-1 the author presents a plain servlet which draws  hard coded values from a pojo called ProductCatalog. The XML values returned in the browser are the ones that are statically hard coded in the pojo's

On the bright side, the text is well written, showing step by step instructions how to proceed with coding in each autonomous chapter. Each code snippet is explained line by line. Some basics of xpath and xquery are presented as well. What is surprising is an introduction to Berkeley DB XML in chapter 13: Storing XML in Oracle Berkeley DB XML. One can find more information on the internet
