Thank you, one small step for me....
I have found the .jar, by the way for a beginner this was not full obvious. But the next error message comes in a msgbox right after I try to run the .jar:
"A JNI error has occured, please check your installation and try again"
What is the correct CLASSPATH entry is Java? Now I have on my 32bit Windows7: .;C:\Program Files\Java\jdk1.8.0_60\lib;
And if I check the logs in B4J, the "compile and run" logs this:
WARN
ejh.MimeTypes:main: java.util.MissingResourceException: Can't find bundle for base name org/eclipse/jetty/http/encoding, locale hu_HU
Is there any connection?
