Hi all,

I am trying to follow the example listed here and I am trying to compile the java file using javac. Following the example, I am running

javac -classpath "matlabroot\toolbox\compiler_sdk\mps_clients\java\mps_client.jar" MPSClientExample.java

where matlabroot is the Matlab installed folder.

I am having the following error message, that suggests I am not linking the classpath properly. I am sure the path to the mps_client.jar is correct and that the file is the folder, but I don't know how to fix the error. Any idea?

Thank you in advance.

MPSClientExample.java:3: error: package com.mathworks.mps.client does not exist
import com.mathworks.mps.client.MWClient;

What is your JDK version? You can find your JDK version from Commamd Prompt.
