thanks for you tip of searching in stackflow.i did it as http://stackoverflow.com/questions/8615226/eclipsenode-js-error-when-debugging-failed-to-connect-to-standalone-v8-vm-con told.

then it works.it does make very sense to me.i wish it can be like debug java in eclipse(.just debug as java application in ide).why do we need debug it in command line first,and then we can debug in eclipse.

[haroldjiang]

sorry,it does not make very sense ,wrong typo

[paulvi]

Question http://stackoverflow.com/questions/8615226/eclipsenode-js-error-when-debugging-failed-to-connect-to-standalone-v8-vm-con is not related to Nodeclipse directly.

Check #72, the reason may be Java version incompatibly.

Please give

• Nodeclipse version number (like 0.5 or 0.6)
• Eclipse version number (like 4.2.2 or 3.8.0)
• Eclipse distribution (e.g. Eclipse for JEE Developers)
• A detailed description of the steps necessary to reproduce the problem.

OS WIN7/64 Eclipse Java Development Tools 3.9.1 Eclipse PlatForm 4.3.1 nodeclipse - http://dl.bintray.com/nodeclipse/nodeclipse/0.8.0/

Eclipse Standard 4.3.1

step to reproduce. 1 right click on the main node js file.it prompts out with a dialog. 2 choose "Debug AS Node Application" 3 get a message of "Failed to connect to Standalone V8 VM Connection refused: connect"

[haroldjiang]

thanks very much for help

[haroldjiang]

by the way after run "node --debug-brk app.js" in command lin first.then do those steps above,you wont get the error message.it works as expecation

[paulvi]

What is your Java version?

Do you mean the solution was to run node --debug-brk app.js first?

[haroldjiang]

java version "1.6.0_30" Java(TM) SE Runtime Environment (build 1.6.0_30-b12) Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)

yes,the solution is to run node --debug-brk app.js first.

[paulvi]

That is interesting. Then maybe #72 was also not about java, but something that should trigger inside Node

[haroldjiang]

yeah,maybe.if click "Debug AS Node Application" without running node --debug-brk app.js first,always get the error message of "Failed to connect to Standalone V8 VM Connection refused: connect"

Nodeclipse 0.9.0 is just released http://www.nodeclipse.org/

Welcome to update

[haroldjiang]

hi,paul.how do i upgrade nodeclipse from 0.8.0 to 0.9.0. if i install 0.9.0 directly in "Install New Software" of Eclipse.will it override the old version. thanks in advance.

[haroldjiang]

i already click the button "Check for updates",it got nothing to update

[paulvi]

that is because every version has it's own update p2 site. check http://www.nodeclipse.org/

I still cannot get it to work

my js file is simple

`
var http = require("http");

// create a http server that writes hello world
http.createServer(function(request, response) {

    // Send the HTTP header 
    // HTTP Status: 200 : OK
    // Content Type: text/plain
    response.writeHead(200, {
        'Content-Type' : 'text/plain'
    });

    // Send the response body as "Hello World"
    response.end('Hello World\n');
}).listen(8081);

//Console will print the message
console.log('Server running at http://127.0.0.1:8081/');

` When I try to debug this as a Node Application, I get following at Eclipse Console

Debugger listening on ws://127.0.0.1:5858/b1bdf38d-c53a-472d-89f8-6819c5e4c8b1 For help see https://nodejs.org/en/docs/inspector

But then V8 fails. I am not sure where I need to make the changes. Below is the error I get.

Nodeclipse/chromedevtools failed to connect to Standalone V8 VM ( Check Help (F1) and Support http://www.nodeclipse.org/#support ) . Info: Timed out waiting for handshake

I am using Node: v8.1.0 and Eclipse Version: Neon.3 Release (4.6.3) Build id: 20170314-1500

Any suggestions?

[bryanpham85]

Seem the issue has been solved somewhere, however I'm still facing this issue with Eclipse Oxygen + Nodeclipse. Constantly got this error message "Failed to connect to Standalone V8 VM Timed out waiting for handshake"

Already set up Debug configuration with argument "--inspect-brk".

Any help much appreciate it!
