Javascript ICE client setup

Hello,
I am trying to create a small javascript/html based ICE client talking to a java server. I am facing some problems setting up the examples that are part of the installer. Could someone please help me figure out what am I missing here ? I went through the documentation but couldn't find much that would resolve my error.
Running Client.js independantly
Below are the steps which I followed to run these applications.
1. cd '...\ZeroC\Ice-3.6b-demos\js'
2. node build.js
3. cd '..ZeroC\Ice-3.6b-demos\js\Ice\minimal'
4. node Client.js
At this point, I get an error saying 'Error: Cannot find module 'icejs''. I tried to manually change the dependency by copying the Ice.js and adding the dependency with an absolute path.
Any idea how could I get it running ?
Running in the browser
By only updating my object adapter with endpoints on the server side to be 'ws -h localhost -p 10000' , I was able to ping the server from the browser. However, I was not able to understand when would I have to use Glacier2 server for communication. I am sorry if I am being naive.
Thanks in advance for help.
Cheers,
Murthy

For the upcoming 3.6.0 Ice for JavaScript will be released as a NPM module, and it will not be part of the installers.
Glacier2 is not required with 3.6b, with the first lab release we only provide Web Sockets support for C++ and if you need to talk to a Java/C# server from a web socket client you need to use a C++ intermediary like Glacier2.
Thanks a lot for the help, it worked

I had a few further queries on what you mentioned.
1. With 3.6b we do not need Glacier2 for communication with a java/C++/C# servers from a web socket client
2. But in the latest stable release (I assume 3.5) Glacier2 is currently required to communicate with Java/C# servers from a web socket client.
Is my understanding as above right ? What exactly did you mean by first lab release ?
When is the 3.6 production release planned ? I would be interested in ice for javascripts and its communication with different ICE servers via websockets.
Thanks in advance for help.

Correct, the WebSocket lab project based on Ice 3.5 only included a C++ implementation for the WebSocket transport and therefore required to go through the Glacier2 service for a JavaScript web socket client to communicate with Java/C# services. This lab project has been retired after the release of Ice 3.6b. Ice 3.6 is due to be released in few days.
