Mobile UI upcoming release

Our mobile flutter UI is just awesome. Just sayin'

The next version will be 2.6.0.

It will fix some smaller bugs and will provide you with a killer feature. It will be possible to use multiple application configurations. Simply switch your JVx based applications.

The application overview will look like this:

Application overview

Application overview

What else?

We have support for haptic feedback and slider button. We improved screen loading and will show a skeleton with loading animation. We have support for flat/text buttons an image viewer and full-screen multiline text editor. The image viewer is automatically available for all your image editors. Simply tap on an image. If you have small multiline editors in your screen, simply double tap to get a full-screen editor.

You want more?

We have edit support for simple tables (single cells or the whole record), we have sort on header and also table reload support. The application API was updated and is now much easier to use. Our example application demonstrates many use-cases but a full API documentation is not available at the moment. This is on our todo-list!

The flutter client for JVx applications is Apache 2.0 licensed and the source code is available here.

JVx' Multi-factor-authentication documentation

The multi-factor-authentication support in JVx is not a brand-new feature but it was undocumented. If you're interested in MFA, simply read the documentation.

If you're also interested in custom REST services, read following article.

The JVx documentation doesn't explain every single feature of JVx, but it's better than you think!

JVx 2.8.5 - Statistics

JVx 2.8.5 is out and we have some Source Code statistics for you!

Our last statistics were determined for JVx 2.2. The source code grew by 50.012 lines, since 2.2. We now have 178.896 (JVx library, Swing UI, tests) compared to 128.884 in JVx 2.2. Still awesome if we compare the features of JVx with any other application framework!

Here are the actual numbers for you:

JVx library   Swing UI
LoC   Type
107.951   Code
86.032   Comments (~ 44% of Code)
28.282   Empty lines
222.265   Total
LoC   Type
41.544   Code
22.321   Comments (~ 35% of Code)
9.249   Empty lines
73.114   Total
 
JVx library (Test cases)  
LoC   Type
29.401   Code
14.620   Comments (~ 33% of Code)
9.649   Empty lines
53.670   Total

Some additional numbers:

Files and Tests
JVx library source files   825
Swing UI source files   148
Test source files   151
Total   1124
Still a small codebase ;) and still very easy to maintain. Here are more numbers, about testing:
 
Unit tests (no UI, without manual perf. tests)   1000
Class coverage (without UI)   73%
Method coverage (without UI)   62%
Our coverage is not as good as with 2.2 but still not bad.

TOP 10 classes

Classname   LoC
DBAccess 5.775
MemDataBook 4.712
JVxTable 2.704
ArrayUtil 2.613
DBStorage 2.237
StringUtil 2.230
Server 2.058
SimpleJavaSource 1.583
PostgreSQLDBAccess 1.495
DateUtil 1.468

This are interesting numbers because in JVx 2.2, MemDataBook was on 1st place. We now have more code for database support than before. The newcomers are SimpleJavaSource and PostgreSQLDBAccess.

We tried to reduce complexity of DBAccess and MemDataBook, but complex things are complex. This is why we develop JVx. It makes complex things, simple.

JVx 3.0 will change something...

The development phase of JVx 3.0 has started. We'll change some things which are important to know:

JVx 3.0 won't be Java 6 compatible. We'll switch to Java 8 and... still super backwards compatible.

We'll also change some package names like javax.rad. But we don't have a complete list right now.
So keep reading.

Log4j - CVE-2021-44228

No worries about CVE-2021-44228.

We have support in JVx for different logging libraries, but use Java logging API per default.
Our product VisionX doesn't use log4j(2) and the log4j2 jar file is not included.

So if you're using VisionX, you won't have any problems.
If you're using JVx without log4j2, also no problems.
If you're using JVx and log4j2, be sure to use one of the latest jdks and you won't have any problems. Also an update to latest log4j2 is recommended.

EPlug 1.2.43 is out

We are happy to announce that our EPlug 1.2.43 is out.

EPlug is our Eclipse plugin for JVx applications and also for our low-code platform VisionX.

The main improvements were a complete redesign and a big performance tuning.
For sure, we have some great new features like:

  • Support for ColumnViews
  • Support for MasterReferences
  • Support for SortDefinitions
  • Support for new Var(...)
  • Metadata cache improvements
  • Avoid compile Errors when columns cannot be checked
  • Show element in tree (one click)
  • Bugfixes

Feel free to try out our new version and send us your feedback.

Es fluttert gewaltig - Artikel

Es gibt seit kurzem einen neuen Artikel über unsere brandneue Flutter App in der deutschen Presse. Hier das Intro:

Wer eine App für mobile Geräte entwickeln möchte, steht zumindest vor einer wichtigen Frage: Mit welcher Technologie soll die App realisiert werden? Da es aktuell verschiedenste Möglichkeiten gibt, ist die Antwort nicht sofort klar. Mit diesem Problem war das Framework-Team von SIB Visions ebenfalls konfrontiert, als es darum ging, einen Client für das Open Source Application Framework JVx zu entwickeln. Wie
vor allem was umgesetzt wurde, wird ...
