JVx 0.8 - Source Infos

Well, after the version 0.8 of JVx was released, it's time for some LoC statistics.

Particularly the clarity and comprehensibility of the Source Code are very important to us. Therefore we are very proud also of the following lines of code.

JVx library   Swing UI

Compared to the features, we have too few lines of code :)
But exactly that makes the difference!

JVxFirstApp update

Im Zuge unseres JVx Vortrages, bei der Java User Group München, wurde berichtet, daß im Download der FirstApp die Konfiguration "config.xml" nicht inkludiert ist. Nach kurzer Analyse wurde festgestellt, daß auch die Server Konfiguration nicht enthalten ist.

Das Fehlen der Dateien ist aufgrund der Schritt für Schritt Anleitung kein großes Problem und kann rasch behoben werden!

Die Ursache für das Problem war eine fehlerhafte build Konfiguration. Diese wurde umgehend behoben und die aktualisierte FirstApp steht bereits zum Download bereit. Im Zuge des Updates wurde auch gleich die aktuelle Release 0.8 von JVx inkludiert.

JVx 0.8 released

JVx 0.8 ist out now!

We put much time and work into the new release. It contains almost 100 improvements!

But before we go into the details, it should be mentioned that JVx is now hosted on SourceForge. This step was particularly important to us, in order to be able to develop together with our Community.

Our Forum contains detailed instructions for working together.
We appreciate any help.

    • Changed, automatic, visible column detection from case insensitive to case sensitive, for compatibility reasons!Old:
