Hi, please provide more information about what you tried so far and what problems you are encountering.
A good place to start is the CheerpJ tutorial: https://cheerpj.com/docs/getting-started/Java-app

I have jar not .jar.js
jar.js files are not used at all since CJ3.0
You are somehow following documentation for CheerpJ 2.3
Please follow the tutorial I have linked

Hey, CheerpJ makes use of a virtual file system since applications that are running in the browser are not able to interact with the local file system out of the box. You can read more about it in our documentation: https://cheerpj.com/docs/explanation/File-System-support
The error you are seeing likely happens because the application is using a local path for file interactions, which does not correspond to the virtual file system. A solution for this would be to create the needed directory structure in the virtual file system and move the needed files there. Or to configure the application to write to the
/files mounting point instead of using cwd.Leaning Technologies Developer Hub
