Clojure Erlang Bridge using JInterface

This library is a bridge between Clojure and Erlang using the library JInterface.

The library is a simple wrapper around JInterface. I'm writing it as a way to learn Clojure.

So far the capabilities are really simply. My goal is to add more features while I learn more Clojure. Feel free to comment on the coding style, on how I can improve it to be more idiomatic Clojure.


First launch erlang with the following command:

erl -sname a

Start the Clojure REPL

Then at the Clojure REPL:

(use 'closerl.core)

(def self (otp-self "b"))

(def peer (otp-peer "a@mrhyde"))

Once we have the nodes we can try to connect them:

(def conn (otp-connect self peer))

Then we do a rpc_call to obtain the date on the remote node:

(otp-rpc-call conn "erlang" "date")

And we call receive to fetch the reply:

(otp-receive conn)


Use mvn to install JInterface. Adapt the following command to suit your specific configuration

mvn install:install-file -DartifactId=erlang -Dversion=1.5.3 -Dpackaging=jar -Dfile=/usr/local/lib/erlang/lib/jinterface-1.5.3/priv/OtpErlang.jar

Obtain the closerl source code

git clone
cd closerl
lein deps
