Data base tables

Within this blog, and especially within my book “Practical JSF in Java EE 8” [1] I described the Books project. Some listings show the structure of the tables which are used by this app. But I did not describe all every table. In my poor opinion I assumed, it would be very simple to create […]

Live continues…

…and so my blog does. You may have wondered that I didn’t have written any article within this blog such a long time. Last year I agreed, when apress asked me to publish a new version of my book “Web Development with Java and JSF”. My book had been a living book so far. I […]

JavaLand slides

My talk about JSF at JavaLand had been a surprisingly great success – more than 200 attendees. I assume my slides will be available soon at the conference web site. For the impatient, here it is too: JSF – the GUI of Jakarta EE

JSF: import constants

With the current version of Java EE 8 / JSF 2.3 we can implement an internal navigation using enums. And this is what we use for Alumni’s [1] navigation. As an example we pick the forgot password link. 1 <div> 2 #{msg.lblForgotPassword} 3 <h:link value=”#{msg.lblRequestPassword}” 4 outcome=”#{Page.RequestPassword.url()}”/> 5 </div> Take a look onto line 4.

Custom Realm

Custom Realm

Do you remember the requirements for secure passwords? • We need an algorithm, which takes some time to calculate to prevent from brute force attacks (or at least to reduce its chance to success). JdbcRealm allows to determine the algorithm. • We need to add a salt to every password to protect against rainbow tables. […]

Securing my WebSites

In my book about web development, I’m describing how to build applications with Java EE 7 and Java EE 8 (including some step by step tutorials by means of NetBeans). One application is a social network app called Alumni. This needs to be secured. I finally installed TLS on my web sites (including this blog), […]

Living book. Pausing soon.

Living book. Pausing soon.

In 2014 I started writing my book “Web Development with Java and JSF”. My intention was to write a book of apx. 200-250 pages. In my book I combined the theoretical background with a practical approach by building real applications. Can you build applications with JSF only? Nope. A JSF app runs within a servlet […]

Impressions from Tenerife II

Impressions from Tenerife II

I took a snapshot down into a Aloa Vera or similar plant. The camera automatically focused onto the ground and the picture shows very clear a leaf at the bottom of this plant. Then I manually focused on that little animal I discovered there. Two photos taken from the same position, showing very different details. […]
