Not sure what I'm doing wrong but it gives some error which I don't really understand. The other kernels which I installed like R, Julia, Wolfram work fine.

Below are installation, console & web notebook outputs.

Win 10
python 3.9.16
jupyter --version

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.

https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html

Please note that updating to Notebook 7 might break some of your extensions.

Could you please go to run_kernel.py from you stacktrace and add print of this list?
[java] + jvm_args + ['-jar'] + debug_list + jar_args

I suspect that you have misconfigured JAVA_HOME environment variable, check it first

Yes, I see, you have java executable in your JAVA_HOME directly, but it should be located in bin subfolder

Yes, I see, you have java executable in your JAVA_HOME directly, but it should be located in bin subfolder

thanks to your clue. I changed the path manually but now I'm getting a different error.

So I did some investigation. Apparently changing JAVA_HOME doesn't make a difference as it still uses the java.exe from the Common Files folder, so I added the new java bin subfolder manually to the PATH and JAVA_HOME.

System default

(jup) C:\jupdir>where java
C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe

Adding new path manually

(jup) C:\jupdir>set path=C:\Program Files (x86)\Java\jre1.8.0_261\bin;%path%

Now bin folder java take priority.

(jup) C:\jupdir>where java
C:\Program Files (x86)\Java\jre1.8.0_261\bin\java.exe
C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe

changed JAVA_HOME to bin folder

(jup) C:\jupdir>echo %java_home%
C:\Program Files (x86)\Java\jre1.8.0_261

Could you please go to run_kernel.py from you stacktrace and add print of this list? [java] + jvm_args + ['-jar'] + debug_list + jar_args

I suspect that you have misconfigured JAVA_HOME environment variable, check it first

I'm not really sure what is the command to print these things but I tried to do a manual print() statement in that file.

java

C:\Program Files (x86)\Java\jre1.8.0_261\bin\java

jvm_args

[]

debug list

['-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044']

jar_args

Thanks for your help. I think it is working now, right?

So I downloaded the JDK 11 and set the JAVA_HOME to java 11.

Yes, it seems that it works now. However it should be compatible with Java 8, I'll recheck it, thanks!

After this commit kernel should be compatible with Java 8 again (except for detecting client type which uses Java 9 API). Thank you again for checking!

I think the fix works.

I also moved java path is back to the C:\Program Files (x86)\Common Files\Oracle\Java\javapath system original and also I removed JAVA_HOME.

It still works. 👍🏼
