The purpose of this tutorial is to illustrate how to use jinterface for communicating with an Erlang backend

The reader is also encouraged to read the mailing list question.It's about 'Strategies to connect from Java' Refer Erlang Manual for more details on jinterface


This tutorial demonstrates how to communicate with an Erlang process (node) using a Java program For this example I have used java 1.5.0_07 and Erlang OTP12B distribution.

PartOne : Erlang Backend

First we need to have a erlang process (node)to communicate with Java program. If we are going to connect to an existing erlang node. we need to know the name of the Erlang node and the cookie. Otherwise we can create an Erlang node. In windows we can create a erlang node by using the command prompt using below command.

    werl -sname enode -setcookie  erlang

For Linux

    erl -sname enode -setcookie  erlang
