AIR apps developed using HTML+Javascript

Hi…

I am working on Adobe AIR.

And now I have 3 options to develop AIR applications 1)Flex 2) Flash 3) HTML+javascript.

But can you please explain me when do I exactly use Flex Or HTML+JS Or Flash.

One of the reason I know is Flex used for Rich UI applications

Is there any list of requirements for which one of the 3 option is most suitable to use.


And I have some more questions.

1) Can AIR applications(developed using HTML+Js) invoke a web service running on a different server

2) Can AIR application(developed using HTML+Js) detect the connectivity of USB drive (I have developed 1 application that can detect the Network connectivity and periodically reports the status I want the same in case of USB(plug & play) connectivity)

3) I have one AIR application that has one HTML form on click of button I am posting the form Data to Java Servlet using “air.sendToURL()” as shown

<script src="AIRAliases.js" />

<script>

function sendURL()
{
var url = " http://localhost:8080/InvokingServlet/Registration";

var variables = new air.URLVariables();

variables.username = document.f1.username.value;

variables.password = document.f1.password.value;

var request = new air.URLRequest(url);

request.data = variables;

air.sendToURL(request);

alert("Data has been added to Remote DB...");

}
</script>

The data goes to Servlet and then Servlet thru Jdbc Connectivity adds the data to database “MySQL” database named “user”

If I read the data from database and print in Servlet it displays that to “tomcat server window(log)” But I want the data from Servlet to send back to HTML page where I can display it on the same HTML page where user entered his details. So even if I put the result into some Scope like session or request, but Can I read that it in HTML+Javascript page .
