java - Android and servlet communication and displaying -

-

I have the name of an Android app that model and String which sends Java Servlet it Adds Weblet's combo box for servlets this is not happening yet, the following exception is seen in Logcat. 

  10-28 14: 25: 05.733: D / Exception (7518) ): java.io.FileNotFoundException: MyServletProject / Connection_Servlet

this is my app code 

  on public void (see V) {switch (V .getId ()) {case R.id.doubleme: new thread (New Runnable () {public void run () {try {uRL url = new URL ( "Http://l92kl68klk5:8080/MyServletProject/Connection_Servlet"); // URL Url = new URL ( "Http: // 10.0.2.2:8080/MyServletProject/DoubleMeServlet "); URLConnection connection = url.openConnection (); string inputString =" 11 ", the string model = getDeviceName (); // inputString = URLEncoder.encode (inputString," UTF-8 " ); Log D. ("InputString", InputString); Log D. ("Input String", Model); Connection.setDoOutput (true); / OutputStream Water Out = New OutputStream Water (connection.getOutputStream ()); Out.write (inputString); Out.close (); * / DataOutputStream Out1 = New DataOutputStream (connection.getOutputStream ()); Out1.writeUTF (model); Out1.writeUTF (inputString); Out1.flush (); Out1.close (); InputStream = connection.getInputStream (); DataInputStream dis = New DataInputStream (); While (dis.available () == 0); String WTF = dis.readUTF (); Dis.close (); Log.d ("Message", WTF); } Hold (exception e) {log d. ("Exception", e.ostustring ()); }}

This is my servlet code 

  protected void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {response.setIntHeader ( "Refresh Do ", 5); Request.setAttribute ("item", list); Request.getServletContext (). GetRequestDispatcher ("/ BarcodeScannerTest.jsp") Forwarded (request, response); } Boolean daton = false; Boolean device_connected = false; Public string model; ArrayList & LT; String & gt; List = new array list & lt; String & gt; (Arrays.asList ("Buenos Aires", "Cordoba", "La Plata")); Protected void doPost (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {// TODO Auto-generated method stub InputStream = request.getInputStream (); DataInputStream dis = New DataInputStream (); While (dis.available () == 0); Model = disk.readUtf (); String input = dis.readUTF (); Dis.close (); Println ("model:" + model); List.add (model); OutputStreamout = response.GetOutputTream (); DataOutputStream Data = New Data Optical Stream (DUTA); Dat.writeUTF ("work"); Dat.flush (); Dat.close (); DoGet (request, feedback); }}  
 url = new URL ("http: 8080 / MyServletProject / Connection_Servlet")

itemprop = "text" ); There was an error in the url I have given the wrong path. Correct url url = new url ("HT: 8080 / Scanner artemption web app / connection server");

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
