Convert this nodejs page to run my own .jar file in browser

This website allows you to run .jar files in the browser including your own shell and ability to save files from java: [login to view URL] Currently to run my own jar file, I have to: 1. Visit [login to view URL] 2. Click start the demo 3. Upload my jar file. 4. Run "java -jar [login to view URL]" (See video attached to see what I mean) Instead I want users to be able to just load my own web page and the jar gets loaded from an HTTP url. A different JS library may have done some of this work: [login to view URL] But I am not sure it supports writing files to disk (which is required) like the first doppio library. The end deliverable I expect is: 1. A standalone HTML file NOT requiring running a nodeJS server but hostable on a static website that allows: 2. Running the [login to view URL] or another specified .jar without the user having to launch it manually. 3. Within that [login to view URL] a user should be able to save files (as shown in the video with the commands below) Ideally I could also: 4. Link to a URL http://xxxxxxxx/jpad?commands="2+2" Where the command 2+2 would be the first commands when the system gets loaded. 5. Show a loading bar as my own .jar loads. 6. Allow pressing the up/down arrow to go to old commands AND pasting commands using ctrl+c/v. I would pay more for these functions. Name your price. [login to view URL] can be downloaded here: [login to view URL] JPad commands used to save a file: Object o = new int[] {1,2,3}; final File file = new File("[login to view URL]"); [login to view URL](o, file);
