jre version issues
Hi
I am not exposed to under the hood of netbeans settings, hence require
hand-holding.
Application is working fine in Netbeans IDE. But when I use a shortcut link
to the jar file or try to run in the console, I get the following error
message.
~~~~~
Error: A JNI error has occurred, please check your installation and try
again
Exception in thread "main" java.lang.UnsupportedClassVersionError:
gabellattemvpn/GabellatteMVPn has been compiled by a more recent version of
the Java Runtime (class file version 62.0), this version of the Java
Runtime only recognizes class file versions up to 52.0
~~~~~
Please inform what changes have to be done and where (Netbeans/Console).
I am using MS Windows 11(or 10).
Warm regards
Amitabh Choudhury

TQ Michael for the info. The JNI error on clicking the short-cut link from
the desktop happens. For now I have set short-cut to a ".bat" file on the
desktop and working around that mode.
Have to looking into this JNI issue.
Warm regards

oh. This sounds like you installed both, a 32bit and a 64bit JVM. Since
windows keeps them separated in those two folders.
java -version should show what is what in case of doubt.
with JNI you have to be extra careful when the architecture changes.

michael

Re: jre version issues

Yes Ernie. I am not getting a JNI error when I attempt to open JAR from
desktop shortcut.
Have to figure out how to reconfigure. There were two folders from Oracle
in the path
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\Program Files\Common Files\Oracle\Java\javapath

Glad you got things going.
I'm guessing that means jdk18 was not installed with the oracle windows
installer. Keep in mind if/when you update to a newer jdk you may need
to fiddle with your path.

Re: jre version issues
Posted by Pieter van den Hombergh <pi...@gmail.com>.
the path is a sequence of directories. the algorithm that tries to find an
executable file uses the directies in path order and the first file in any
directory that matches the request is the one used. so adding a directory
at the end will have no effect if an earlier directory satisfies the
request.

Re: jre version issues
Posted by Amitabh Choudhury <am...@gmail.com>.
Hello Alexander and Ernie
Thanks for the reply.
Was able to get into the System variable of Windows 11 and found that
"Path" started with "C:\Program Files (x86)\Common
Files\Oracle\Java\javapath".
Even though 1.18 was installed and placed in "Path" at the end, the x86
javapath was being picked up and had version 1.8.
deleted the string from "Path" and was able to get the app (GabellatteMVPn)
running.
Meanwhile got aware of (https://javaalmanac.io/bytecode/versions/). TQ
Ernie.

And of course, you can use the jdk/jre that NetBeans runs on to execute
your jar file.

Taking a look at https://javaalmanac.io/bytecode/versions/
I see that 52 is java 8, 62 is java 18.
Your jre is java 8 (presumably this is the default jre on your windows
system), you compiled it (assuming GabellatteMVPn is yours), on java 18.
I'd be inclined to update your system with a newer jre. The alternative
is to compile your program to run on java 8.
