GWT发送到远程服务器？

Question

I have a xml document I need to send to a remote server that isn't mine.

I have the url and port number for the remote server, and I've tried to implement the transfer using RequestBuilder.

Code Example:

RequestBuilder req= new RequestBuilder(RequestBuilder.POST, URL.encode(url));

req.setHeader("Content-Type", "application/x-www-form-urlencoded");
Request response = 
    req.sendRequest(message, new RequestCallback() {
       public void onError(Request request, Throwable exception) {  
           exception.printStackTrace();
       }
       public void onResponseReceived(Request request, Response response){    
           System.err.println(response.getText());    
       }
    });
} catch (RequestException e) {    
    Window.alert("Failed to send the request: " + e.getMessage());    
}

If this isn't the way to do it, it would be greatly appreciated if anyone could explain what must be done.

Btw the error I'm getting is:

Failed to send the request: The URL www.test.net:8909 is invalid or violates the same-origin security restriction

Answer 1

Simply stated, the Same Origin Policy states that JavaScript code running on a web page may not interact with any resource not originating from the same web site. The reason this security policy exists is to prevent malicious web coders from creating pages that steal web users' information or compromise their privacy. While very necessary, this policy also has the side effect of making web developers' lives difficult.
