Today I launched my new web site http://webdevelopment-java.info. This site is related with my book “Web Development with Java and JSF”, which is a superset of my “Tutorial web development (with JSF)”. In fact, this book contains much more info than my tutorial. By now, there isn’t much content on my new site. However, source […]
I just published the first version of my book “Web Development with Java and JSF” (and with a bit of NetBeans too) . It’s in an early state now. Start reading yet and get all updates for free. Enjoy!  https://leanpub.com/jsf
Developing web applications with Java, JavaServer Faces and NetBeans had been a great pleasure (and success) to me for a couple of years, when I first wanted to write a book about JSF in late 2010. At this time, I got in touch with some German publishers. My goal was to write apx. 200-250 pages […]
To prevent injections and other attacks, input validation is a kind of must. JSF supports this by its own validator concept.

So far, I recognized a lot of visits, and some people reported similar problems in their comments. Beside the possible solution I described in my blog, memory tuning seemed to help. Read […]
I recently visited the German conference for parallel programming. Read my report  (German).  Parallel2014 – klein, aber fein
Java 8 introduced some impressive new features. Lambdas in conjunction with Streams finally support a functional style of programming. But, unlike LINQ of the .NET world, there is no operator to join streams. Thus, I tried to join streams manually. My approach is to use second a stream in a lambda expression within a map […]
Ok, we secured our JSF web application by using a JSF form. The user information is still stored in a flat text file. But as stated before, your application server provides more. This lesson, we move forward to GlassFish’s JDBCRealm, which allows you to store the user information within the database.
