Bind Error

ctranfd

Hi again,

I'm now trying to work on the real example on my machine and am coming across the same problem when I add the "environment" to the URL (local, uat, stage... etc).

The set up is as follows:

Domain: local.mysite.com
Web: local.www.mysite.com
Port: 8071
Lighstreamer: local.lightstreamer.mysite.com
Lightstreamer Port: 8090

However I have a feeling that the entries in my host file conflicts with how the domain is being interpreted.

127.0.0.1 local.mysite.com.au
127.0.0.1 local.www.mysite.com.au
127.0.0.1 local.lightstreamer.mysite.com.au
127.0.0.1 local.www.lightstreamer.mysite.com.au

This is what I have on the client side:

<script language="JavaScript" src="http://local.www.mysite.com.au:8071/lightstreamer/js/lscommons.js"></script>
<script language="JavaScript" src="http://local.www.mysite.com.au:8071/lightstreamer/js/lspushpage.js"></script>

<div table="hellotable" item="item-test" field="field1">
loading...
</div>

<script>
var page = new PushPage();
page.context.setDomain("local.www.mysite.com.au");
page.onEngineCreation = function(engine) {
engine.context.setDebugAlertsOnClientError(true);
engine.connection.setLSHost("local.www.lightstreamer.mysite.com.au");
engine.connection.setLSPort(8090);
engine.connection.setAdapterName("PROXY_HELLOWORLD_SOCKETS");
engine.changeStatus("STREAMING");
}
page.bind();
page.createEngine("HelloWorldApp", "lightstreamer/js", "SHARE_SESSION");

var pushtable = new OverwriteTable(null, null, "MERGE");
pushtable.setPushedHtmlEnabled(true);
pushtable.setSnapshotRequired(true);
page.addTable(pushtable, "hellotable");
</script>

I also noticed that I needed to specifically put the "www" in the page domain and lightstreamer host.

Many Thanks,

given that your web server is reached throug local.www.mysite.comand that your lightstreamer server is reached through local.lightstreamer.mysite.com , you can't use local.mysite.com as domain as it doesn't match neither host.

Hosts and domain must respect the "same origin policy".
So you should use as domain only mysite.com.

If you prefer/need a longer domain, another possibility is the following:
Web Server: www.local.mysite.com
Lightstreamer Server: lightstreamer.local.mysite.com
Domain: local.mysite.com

Hope that helps.

Note that Opera poses further limits to this policy. Check these thread for details: http://www.lightstreamer.com/vb/showthread.php?t=28and http://www.lightstreamer.com/vb/showthread.php?t=96

Hi Mone,

Thanks for your reply. Unfortunately, we're unable to change the way the URL is constructed for our web app. I don't envisage the domain issue to be a problem when we go live, but we would require users to test on the UAT and Stage environments before we go live.

Is there another way in which we could keep the subdomain "www" in the URL (local.www.mysite.com)?

I've also tried:

domain: local.www.mysite.com, local.mysite.com
web: web.local.www.mysite.com, web.local.mysite.com
lightstreamer: lighstreamer.local.www.mysite.com, lighstreamer.local.mysite.com

Many Many Thanks,

C

I can't understand why sometimes you use host/domain names that end with ".com.au" and sometimes you use names that end with ".com".
May you also clarify which constraints your application server imposes you on the names you can use? Does it also affect the generation of javascript code?

Referring to the above client code, setting

page.context.setDomain("mysite.com.au");

should work.
Moreover, as the domain is only a pattern, you don't need a hosts file entry for the domain name.

Hi Dario,

Sorry that was just a typo - I was removing the name of actual site that I'm working on. So for this case, I've tried to keep it generic to mysite.com.
Just to clarify, I use the hosts file for testing locally (as the site is currently live, but without the new functionality I'm currently working on).

When we go live with the new functionality, there shouldn't be a problem with using:

Site: mysite.com
Web: www.mysite.com
Lightstreamer: lightstreamer.mysite.com

The problem arises when we include the environment (local, uat, stage) and "www" in the URL, such as local.www.mysite.com.

Is there something else I need to do for this to work?

Many Thanks,

C

Setting the domain to "mysite.com" should work also with longer hostnames, provided that all of them end in "mysite.com".
Did you try it and find any problems?
Or is the "mysite.com" domain name unacceptable in your testing environment?

The name combinations that you reported should work as well.
I Refer to:

domain: local.www.mysite.com
web: web.local.www.mysite.com
lightstreamer: lighstreamer.local.www.mysite.com

domain: local.mysite.com
web: web.local.mysite.com
lightstreamer: lighstreamer.local.mysite.com

If you had them not working, then the problem may no longer be related to domain name choice.
Please concentrate on one of the above cases and provide us with more detais.

Hello,

I managed to get it working with the following:

domain: mysite.com
web: local.www.mysite.com
lightstreamer: lightstreamer.mysite.com

The site that I work on dynamically builds the location of files that are placed in a "static" file directory to be in the site root directory (i.e. mysite.com/).
The problem turned out the html files in the ls directory (mysite.com/ls) were not getting resolved properly (ie. not resolved to be in mysite.com/ls).

Thanks for all your help :Smile_Ab:

Hi.

I've read this thread and a couple more regarding "Unable to find the engine", but I still have a problem. I have LS and an IIS 6 webserver on the same machine. LS is under the default 8080 port. My Data Adapter is a C# adapter successfully opening the TCP ports specified in adapters.xml when started.

These are my configs:

Hosts file:
127.0.0.1 localhost
127.0.0.1 archtst1.test.alaskaair.com
127.0.0.1 push.archtst1.test.alaskaair.com

Client script:

<script type="text/javascript">
var page = new PushPage();
page.context.setDomain("archtst1.test.alaskaair.com");
page.onEngineCreation = startEngine;
page.bind();
page.createEngine("CBOFlightPublisher", "JSLib", "SHARE_SESSION");

function startEngine(engine)
{
engine.connection.setAdapterName("LSADAPTERDEMO");
engine.changeStatus("STREAMING");
engine.connection.setLSHost("push.archtst1.test.alaskaair.com");
engine.connection.setLSPort("8080");
}

var pushtable = new OverwriteTable(null, null, "MERGE");
page.addTable(pushtable, "EventTargetTable");
</script>

Any feedback will be most appreciated.

hi Guillermo, please see my reply in the other thread.

Hi Guillermo,

Try putting these host entries:
127.0.0.1 localhost
127.0.0.1 alaskaair.com
127.0.0.1 test.alaskaair.com
127.0.0.1 archtst1.test.alaskaair.com
127.0.0.1 push.alaskaair.com

If it helps, this was what I had:

127.0.0.1 local.mysite.com
127.0.0.1 local.www.mysite.com
127.0.0.1 lightstreamer.mysite.com
127.0.0.1 lightstreamer.www.mysite.com

And the javascript was set up like this:

var page = new PushPage();
page.context.setDomain(" mysite.com");//for you, try: alaskaair.com

//create the engine
page.onEngineCreation = function(engine) {
engine.context.setDebugAlertsOnClientError(true);
engine.connection.setLSHost("lightstreamer.mysite.com"); //for your case try: push.alaskaair.com
engine.connection.setLSPort(8090); //for your case 8080
engine.connection.setAdapterName("MyAdapter"); //change to your required adapter
engine.changeStatus("STREAMING");
}
page.bind();
page.createEngine("MyApp", "http://local.www.mysite.com/LS", "SHARE_SESSION"); //for your case, http://archtst1.test.alaskaair.com/JSLibor move the JS files to http://archtst1.test.alaskaair.com/LS

Hope that helps!
