NetBeans and Java EE: Code navigation

NetBeans offers some shortcuts for code navigation. Click the mouse pointer onto a method name (or focus the name by keyboard) and press Alt-F7. This finds all usages of this method.

Focus the usage of any method and press Ctrl-B takes you to the definition of this method.

So far, this is just behavior of a good Java editor. But what about Java EE?

Java EE covers JSF as web frontend technology. Within your webpages you may use methods. Ctrl-B takes you from such a usage within your (X)HTML directly to the Java definition. And Alt-F7 on the Java method finds the usages within your pages.

Enjoy!

NetBeans and Java EE

NetBeans [1] is a free IDE, which originally focused on Java. Thinking of web development, the developer also needs to deal at least with CSS, HTML and JavaScript. Thinking of the JVM, there are Clojure, Groovy, Scala and others. NetBeans supports them as well, mainly by its powerful plugin system. Beside that, NetBeans offers strong support for languages like C(++) and PHP.

Although NetBeans today supports a couple of different languages, the main focus is to integrate well. Modern applications are commonly web applications, or at least contain a web based user interfaces. The Java Enterprise Edition is a de facto standard to built business and industrial applications (to avoid a holy war: beside Jave EE other software exists to perform theses tasks). NetBeans offers excellent support for this edition. Simply download the NetBeans Java EE edition and you might use the full software stack out of the box.

I want to present some useful small features of NetBeans, tips and tricks for the development with Java EE. I’m going to start a loose series in this blog soon.

Enjoy and stay tuned!

JSF LoopProblem

I inserted a chapter called Intermezzo into my book, which tackles some common aspects of JSF. Unlike the other chapters it is not specific to one of the discussed web applications. Today I described a problem with repetitive structures. A demo for the different loop handlers is available for download. Weiterlesen

Parallel 2015

For the second time, I visited the parallel conference (Parallel2015) [1]. This conference gave a great inside into the state of art of parallel and concurrent programming. Read my report online [2] (Ger). I talked about „Java Lambdas and (parallel) Streams“. You may download my slides from this site [3] (Ger).

To prepare my talk, I created a demo project using NetBeans. Try out its great support for Lambdas and Streams!

JavaLand 2015 & Java aktuell

Last week I visited JavaLand 2015. This great software conference [1] with lot of community activities resides in my home town Brühl [2].

Beside attending lots of tracks I had the opportunity to meet a couple of people face-to-face like Ed Burns (JSF Spec Lead), Geertjan Wielenga (NetBeans product manager), Arun Gupta (Java EE evangelist) and more, especial lot of JUG members from all over Germany. Read an article about my impressions [3].

Most slides are available for download now [4].

And I had the chance, to attend the celebration of 5 years Java aktuell, the Java magazine by the iJUG [5]. Great!
