Rise JVM is a minimal Java VM based on WASM. No server needed.

Live Demo

This is only a frontend of Rise JVM Core.

Automatically via GNU make:

make all

For TinyGo users:

tinygo build -o main.wasm -target wasm ./main.go
cp $(shell tinygo env TINYGOROOT)/targets/wasm_exec.js .

For Go users:

GOARCH=wasm GOOS=js go build -o main.wasm main.go
cp "$(shell go env GOROOT)/misc/wasm/wasm_exec.js" .

We recommend TinyGo instead of Go, which results in a smaller binary size.

These features are tested and work well:

• Simple Integer Arithmetic
• Calling functions
• System.out.println
• Creating Objects
• Looping

Not working yet:

• Polymorphism
• Standard Input

You can find implemented opcodes here.
