var bpmn = require('../lib/public.js');
var path = require('path');

var port = 9998;
var urlMap = {
    "TaskExampleProcess": path.join(__dirname, "./resources/projects/simple/taskExampleProcess.bpmn")

// Returns a restify server.
var server = bpmn.createServer({urlMap: urlMap, logLevel: "debug"});

server.listen(port, function() {
    console.log('%s listening at %s',, server.url);


var restify = require("restify");

// This example used the node-restify client
var client = restify.createJsonClient({url: "http://localhost:9998"});'/TaskExampleProcess', function (err, req, res, obj) {
  • step1:I run server.js,it has no errors,console ouput as follows
BPMNProcessServer listening at http://[::]:9998
  • step2:Then I run client.js,console ouput as follows:
