How to update a .jar file in Matlab?

I have a jar file that I use in Spring Boot project and allows me to process with Matlab. Since this file was written with R2018a version 9.4 and Java 11, I have problems using it again. How can I update this .jar file for R2023a 9.14?

Hi Rozerin,

Based on my understanding, it seems that you are trying to update the .jar file for MATLAB R2023a. To update .jar file, I suggest utilizing the 'javaaddpath' method, which allows you to add one or multiple folders or Java Archive (JAR) files to the beginning of the current dynamic class path.

Please refer to the following MATLAB documentation for more information on ‘javaaddpath’ method.

I hope this helps you in updating the .jar file.

Best Regards,

Sachin.
