} `How can I use this? I need to integrate this with jsp by default swf file is embedded in jsp. How can I save only username (email-id)? If user reenters again it should show in dropdown. how can I pass text input text into the cookie? Please help me in these Thanks in advance.

The posted code uses the ExternalInterface class to access the browsers cookies through JavaScript. I guess your question is about how to use that class. Here you go:

// Initialize the object: 
var cookie:Cookie = new Cookie("NAME OF THE COOKIE");

// Retrieve and trace the value of the cookie:
trace(cookie.value());

// Set new value for the cookie:
cookie.value = "NEW VALUE";

I cannot answer the remaining questions about the drop down. You'll need to be more specific what your actual question is.
