My SmartGWT application connects to external web-application, which generates jasper report in XLS format. This web-application returns binary data (XLS file) or error message, therefore I cannot use just Window.open feature from GWT. How can I offer save dialog with downloaded "rawData"?
Code:
RPCRequest req = new RPCRequest(); req.setActionURL("http://myservlet/"); RPCManager.sendRequest(req, new RPCCallback() { @Override public void execute(RPCResponse response, Object rawData, RPCRequest request) { String contentType = ((String)response.getHttpHeaders().get("Content-Type")); // if error msg if (contentType != null && contentType.contains("text/html")) { // show error msg SC.info("Error message: " + rawData); } else { // want to save downloaded file (rawData) } } });
