macromedia flash flash remoting: Hello,

I have a bunch of servlets already written. Now I have to use them with new
flash pages. I am using Flash Remoting with Flash MX 2004 and Jrun4. I was able
to invoke the servlet from the Flash. But how can I pass the parameters, the
servlet is expecting. For example I have a Logon.java servlet . It is expecting
two parameters 'userid' and 'password' in the HttpServletRequest. The action
script I am using is as follows:

#include "NetServices.as"

NetServices.setDefaultGatewayUrl("http://localhost:8101/flashservices/gateway");
gatewayConnection = NetServices.createGatewayConnection();
servletService = gatewayConnection.getService("compass", this);

function logon_Result(result)
{
_root.output.text = result;
}

function logon_Status( error )
{
_root.output.text = error;
}

In the login button actions I have placed the following code.
on(click) {
_root.servletService.logon();
}

It is invoking the logon servlet on the server. but I have to pass the
parameters and handle the results which it returns.

Thanks & Regards.

You invoke your servlet like any other remoting object:

servletService.ServletNameGoesHere( userID, password );

Except you use your servlet's name as the method name.

On the server side, your servlet's service method is invoked. You extract the
FLASH.PARAMs attribute:

List params = (List)request.getAttribute("FLASH.PARAMS");

Your userid should be the first parameter (params[0]) and the password the
second (params[1]).

There may be other ways to do this, but this way is working for me.

Thanks for the solution. But the main thing here is we have to change the
servlet to read the parameters. I don't have any authorisation on changing the
servlet. Is there any way that I can reuse the servlets as it is?

Thanks & Regards.
