Probably it would be usefull (JSP variant):

    private void printSaveStringButton(String fileName, String content) throws Exception {
        //add new invisible container with write / save functions
        out.println("");
        //save string in js variable
        String jScript = "\n" +
                "var SaveHelper = {\n" +
                "    content : null,\n" +
                "    saveContent : function(filename, text) {\n" +
                "        text=(SaveHelper.content!=null)?SaveHelper.content:text;\n" +
                "        var doc = document.getElementById('xmlContentId').contentWindow.document;\n" +
                "        doc.write(text);\n" +
                "        doc.execCommand(\"saveAs\",true,filename);\n" +
                "        doc.close();\n" +
                "    }\n" +
                "};\n" +
                "SaveHelper.content = '" + org.apache.commons.lang.StringEscapeUtils.escapeJavaScript(content) + "';\n";
        out.println("");
        //add button that writes content into iframe container and show save dialog.
        out.println("Save as...");
    }
