When executing the command parpool() from the MATLAB prompt, with or without arguments, the following error occurs:
Undefined variable "com" or class "com.mathworks.toolbox.distcomp.pmode.SessionInfo.NULL_SESSION_INFO".
Error in parpool (line 96) sessionInfo = com.mathworks.toolbox.distcomp.pmode.SessionInfo.NULL_SESSION_INFO;
The error message seems to be helpless. How can I fix it?

This looks like an installation problem. I suggest contacting MathWorks support.

Did you start matlab with the -nojvm option, I got the same error when staring matlab using "matlab -nodisplay -nojvm"and and starting matlab using "matlab -nodisplay" solved it for me.

I had the same problem when using (as documented here) :
matlab -nojvm -nodisplay -nosplash
But I manage to make it work without the -nojvm
matlab -nodisplay -nosplash

Can you provide the complete error message? Are you able to validate the profile successfully? Also, did you start MATLAB with -"nojvm" option?

Have you tried to validate your cluster profile?
