Wait for the Installed java kernel into "/usr/share/jupyter/kernels/java"message,
Refresh the browser page,
Execute any cell with Java code and get Java output.
Now, I can execute the first cell and get the "Installed java kernel" message,
but after refreshing the page,
the status of the notebook is stuck at "Connecting" forever.
I'm using Google Colab for free, but since the initial installation works, and the notebook status is "Connected" before the page is refreshed, this should not be the problem.
Any idea what has been changed, and how I can get my Java notebooks to connect again?
I was informed by a student of mine that all my notebooks stopped connecting, after the initial IJava installation and browser page refresh.
What used to work:
Execute this first cell
!wget https://github.com/SpencerPark/IJava/releases/download/v1.3.0/ijava-1.3.0.zip !unzip ijava-1.3.0.zip !python install.py --sys-prefix
