html post origin,html - having problems integrating Kaazing with my website: Unable to post message ...

I keep getting the error trying to integrate Kaazing jms version with my .net website and activemq message broker:

Unable to post message to http://www.xgateway.com:8001. Recipient has origin http://www.x.com.

When I try to build a javascript client that is hosted by my Asp .NET website trying to connect to kaazing gateway.

I know I have everything setup ok, because i can go to www.xgateway.com:8001 and i can browse all the documentation and run the demos. I have run the stock ticker demo and watch it work perfectly. so all setup seems OK.

Now the problem is, I also have my asp .net website hosted on IIS 7 on the same machine. i'm trying to build javascript clients hosted on my .net website (port 80) that connect with the kaazing gateway. But I keep getting the above cross origin error.

In my client I am referencing StompJms.js as instructed. I have activemq setup up properly and working as well as the message broker. All demos working prove everything is setup properly.

i have also taken these steps following the instructions in the documentation:

Copy the file GATEWAY_HOME/lib/client/javascript/PostMessageBridge.html and serve it from the source origin web server (http://www.example.com); for example at http://www.example.com/bridge/PostMessageBridge.html.

Note: You must ensure that the file PostMessageBridge.html is hosted on the same origin (same scheme, host, and port) as the web server.

Add the following tags (shown in lines 2 and 3) to the section of your main application page:

content="http://www.x.com/PostMessageBridge.html" >
