In 2024, JavaETK 1.4.4 may not be compatible with the Java Development Kit (JDK) version 21.

Shall I change the Compiler compliance level" to a version supported by JavaETK 1.4.4 (e.g., Java 8 or Java 11) or if there is any other latest version supported by Java etk 1.4.4.

Furthermore, 
I get error when I try to use the following line of code:

System.out.println("eWON JavaETK Version: " + ewonitfVersion);

Exception occurred executing command line. Cannot run program "C:\Program Files\javaetk_1.4.4\bin\java" (in directory "C:\Users\MyUser\eclipse-workspace\JavaPackageCom_Ewon_EwonITF"): CreateProcess error=2, The system cannot find the file specified.
There is no java.exe file in bin folder!
Please help me with the aforementioned.

Many thanks again.

  Hello iot!

  You can find a Guide on how to set up the Ewon JAVA toolkit v1.4.4 with eclipse here:

  https://developer.ewon.biz/content/java 

  https://developer.ewon.biz/system/files_force/AUG-072-0-EN-%28JAVA%20J2SE%20Toolkit%20for%20eWON%20Flexy%29.pdf?download=1

  We only support J2SE JVM 1.4

  You ask about the Compiler setting. Java 8 and 11 are based on JAVA SE not J2SE.

  Here is a Version history: https://en.wikipedia.org/wiki/Java_version_history 

  As you can see in the history you need to choose an older one.

  As for basic tips on how to use Println: Maybe try only text first before trying to access any variables.

  For more in depth support on how to setup your environment please contact your Distributor you can also consult the developer Forum: https://techforum.ewon.biz/
