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: ```...

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.

Is WebVM faster on x86_64 hosts compared to arm64 MacOS hosts?

I am evaluating WebVM as a tool to sandbox a "playground" environment for a internal company compiler tool as it allows us the ability to run unmodified linux-x86 (does it support 64 bit binaries?) binaries which simplifies our execution environment as compared to compiling the compiler to WASM and writing JavaScript bindings. One concern I have is that the performance is quite poor - but I have only had the chance to evaluate it on an M1 MacBook Pro host so I am wondering if x86 translation is the cause of this poor performance? Is WebVM faster on an x86_64 host? If so, are there plans to add support for linux-arm64 virtualization so arm hosts can perform better?...

Commercial use help

Hi! Looking at licensing for commercial use and want to test it first but running into issues. Can you assist? Can provide the JNLP file in a DM.

Cheerp ELF execution failed

I always get [1:1] ELF execution failed [-2]: /opt/ibm/java/jre/bin/java error. Also with bash or ls with own custom ext2 image and with the debian_large_20230522_5044875331.ext2 or debian_mini_20230519_5022088024.ext2. Does anyone know what i am doing wrong? Or is there a way to get more debug logging?
