How do I send an XML document to the client in GWT?

Question

I have this piece of code:

public void generateXML(DynamicForm form) {
        Document doc = XMLParser.createDocument();

        Element root = doc.createElement("root");
        doc.appendChild(root);

        Element node1 = doc.createElement("node1");
        node1.setAttribute("attribute","test");
        node1.appendChild(doc.createTextNode("my value"));
        doc.appendChild(node1);

        Element node2 = doc.createElement("node2");
        node2.setAttribute("attribute","anothertest");
        doc.appendChild(node2);
        System.out.println(doc.toString());
    }

How do I send this document to the client for download without storing it in a directory?

It really depends on how you wish to process it on client side.

If you wish the file downloaded popup to appear for user then follow How can a user download a file in client side (Google Web Toolkit)

If you wish to process the xml file download to display it some chart/etc then use request builder concepts with gwt xml processing.

Hard to say "NO".But its true.

You cannot do it on client side itself.Gwt(Javascript) does'nt have permission to write the content into user drives.

You have to make a request.(ex:FileDownLoadServlet).

Anyways you have to make a request to server.
