CheerpJ usage patterns... ?

For some background: We have a native application that we have ported to WASM. This native version has features that run a JVM, manage it, load and run code in it, and communicate over JNI/JNA. I'm trying to get a handle on how we might use CheerpJ here, and wondering where to start. It's not as simple as run this lib from this web address... jar files would exist on a WASM filesystem. We also use features like a security manager....

Hello I am trying to open a webpage from an Asrock Rack motherboard so I can view the bios

of the motherboard through a webbrowser but it works wiht java, but I tried to open it but it won't open. I installed this extension but no luck yet.

Possible?

Hello. I need to solve this on client side: Pull down a git repo of 3 mb and save all files client side in browser Run a python script to modify these files Upload to same git repo ...

Page Loads Blank

I am trying to access a Tripp Lite SNMPWEBCARD web interface that uses Java Applets. Currently I have to access it by using the Pale Moon browser along with JRE version lower than Update 8 v71 as apparently that version does not allow MD5 for certificates. I am not a developer and don't really know much about how this works. I am a systems administrator though so I'm not completely illiterate with computers. I am not sure what information I need to provide to help and I hope this is the right place to ask for help. When I load the page without CheerpJ it directs me to learn about appelets. With the extension it loads the "frame" that the interface would appear in but it's just a blank white page along with the learn about applets text below. The text part is normal....

Running Steam through CheerpX

Hello all, If possible, I would like to run an application file, specifically Steam, in a VM in the web. I don't know if this is possible since Steam isn't 32 bit but I would like to at least try. If anyone has any other solutions that would be great as well. Thanks :D...

Issue loading game

Attached are demos for two games from the same series, one that loads with CheerpJ and one that will not. Both are able to load with Java 8 through the terminal. The broken demo begins to load in CheerpJ, but then stops suddenly. I am using the 6 Dec CheerpJ build. Due to the filepath requirements in the html files, you will need to place the demo folder at the root of the test web server or change the filepath within the html files.

Issue loading game

This game is unable to load. All of the other java games in this series load great in CheerpJ. No error messages are coming through in the console. I've tried running in both Edge and Firefox. I'm using the 5 Dec build of CheerpJ.

Custom device in CheerpX

How easy would it be to write a custom device for CheerpX? I'm interested in a device that can provide an async function to handle all file access within its mount point, responding with data that's already available in the browser client.

Firefox Issues

Are there any known issues with CheerpJ compatibility with Firefox? I've had a few issues with applets not being able to load on Firefox. These same applets load just fine in Chrome and Edge.

When adding tailscaleAuthKey, nothing loads and no console messages

I have an exit node set up on centos, and select the exit node through the app on my phone and lookup my IP to verify everything with the exit node is working. My jar runs (to the point that it can without networking) on both my phone and pc, but if I add tailscaleAuthKey: "MY_KEY", nothing runs and there are no browser consoles messages to suggest anything is wrong with my key

Verbose compilation

Anyway to develop a progress bar for the compilation process? I found "preloadProgress" in CheerpJ docs for the init function but I'm pretty sure it doesn't provide information about how far the browser is with compiling the program.

Java Compilation on CheerpX and not CheerpJ

Hey i'm new to using Cheerpx, and I think its super cool! I've been playing around with my fork of https://github.com/leaningtech/webvm and seeing how I can change the Dockerfile. My current objective is to have Java work on my container. While I could just use Cheerpj, I wanted to be able to support user input through Scanner (and as far as I know, this isn't supported with CheerpJ) and also have more file flexibility. Has anyone figured out how to do it? Here's my Dockerfile: ```...

Downloading documents in the /files/ file system

I've written a Linux manuscript and I'd like to host WebVM for the exercises.

Hello, I've written a Linux manuscript and I'd like to host WebVM in an environment for the exercises in the book. I plan to keep the environment free for anyone to use but customized with exercises so people can practice learning Linux while reading the book and if they want they can follow along with a Capture the Flag, for learning Linux. My reason for being here is to explore using WebVM before I start building the environment. My first question was if there is support, which it appears there is, next is there any licensing issue if I host it on my own domain and infrastructure, and would Learning Technologies be interested in a shout out in the book or some sort of relationship more than me using your product for my readers?...

I keep getting these errors when trying to run my Java app

I have compiled my Java code (including the dependencies) into a Jar file, which runs smoothly. However, when I try to use CheerpJ, I keep these errors.
