I want to save data from *HttpServlet* to *DataStore*.
*--> HttpServlet*
@Override
public void doPost(HttpServletRequest req, HttpServletResponse res) throws
ServletException, IOException {
/**
* response
*/
res.setContentType("text/html");
final PrintWriter out = res.getWriter();
/**
* request
*/
final String strData = req.getParameter(Constants.REQ_DATA);
MyData data = new MyData(strData);
MyServer.getService().createData(data, new AsyncCallback<MyData>() {
@Override
public void onFailure(Throwable caught) {
// TODO Auto-generated method stub
}
@Override
public void onSuccess(MyData result) {
// TODO Auto-generated method stub
out.println("success!");
out.close();
}
});
}
But I get error in this line MyServer.getService().createData(data, new
AsyncCallback<MyData>() {
*--> Error*
