I have generated a java library named example.jar.
I have already setted JAVA_HOME and CLASSPATH as follow:
JAVA_HOME:
CLASSPATH:
Path with jdk:
Java version from MAtlab command line:
My function takes 3 inputs (3 paths) and has no outputs.
Once the jar has been created I am trying to launch jar file from windows prompt with the following command:
java -cp MyJar.jar "C:\Program Files\MATLAB\R2021b\toolbox\javabuilder\jar\javabuilder.jar" 'path\file1' 'path\file2' 'path\file3'
And I'm receving the following error:
Error: impossible to find or upload the main class C:\Program Files\MATLAB\R2021b\toolbox\javabuilder\jar\javabuilder.jar
Caused by: java.lang.ClassNotFoundException: C:\Program Files\MATLAB\R2021b\toolbox\javabuilder\jar\javabuilder.jar
Any suggestion?

I'd strongly recommend that you create a "sample" with the Compiler SDK. Then the output will contain a getting started guide with the exact steps to run that sample and the sample will execute:

Packaging...
Failed to package Sample Generation for "quote_fun_all3Sample2.m". Additional details:
Error detected while evaluating example. "Undefined function 'pointCloud' for input arguments of type 'double'."
Creating the bundle...
Self contained installer created at C:\Users\Lorenzo Bernardi\OneDrive\Documenti\MATLAB\QuoteFunAll3\for_redistribution\MyAppInstaller_mcr.exe.
Packaging complete.
Elapsed packaging time was: 21 seconds.
I did'nt check the Logfile.
It seems that the problem is with the pointCloud method.
In the code I have the following instruction:
TR = stlread(filename);
ptCloud=pointCloud(TR.points);
