We created a simple sample HTML page using a remote data source and listgrid component, based on some of the examples in BDN. We created a simple servlet which is running the new DatamoduleServlet recently released. Two problems:

1. In Firefox, we are getting a "permission denied error when calling XMLHttpRequest.open".

So, switching to IE, we now have the page loading in the browser and sending a POST request to the server (as seen in the BB debugger):

request=%7B%22read%22%3A%7B%22attributes%22%3A%7B%22page%22%3A%221%22%2C%22rows%22%3A%2210%22%7D%7D%7D

However, the server side (in the servlet?) is returning this error:

GENERIC: XML Parsing Error: Invalid at the top level of the document.Location:
Line Number 1, Column 1:
Text:Exception org.xml.sax.SAXParseException: Content is not allowed in prolog.
-^. sourceText1.

So now we're stuck.

Questions:
1. Why will this not work in Firefox???
2. What are we doing wrong with our request to the servlet?

and, most importantly:

3. Where is the source code for the Data Services? It would greatly help in understanding how to use this component, since the documentation is very very thin.

Thanks...
