Duvida POST

#1

Galera é o seguinte estou montando um midlet que acessa um servlet, ele funciona corretamente, o problema surge no momento em que mudo a forma de transmissão de GET para POST, segue abaixo os codigos.

MIDLET

Método utilizado GET “FUNCIONA CORRETAMENTE”

private void verifica_Login() throws IOException { String url = "http://localhost:8084/RKAM_ServLet/ServLet?"; url = url + "login=" + loginScreen.getUsername() + "&senha=" + loginScreen.getPassword() + "&metodo=LOGIN"; //String url = "http://localhost:8084/RKAM_ServLet/ServLet"; HttpConnection http = null; //OutputStream out = http.openOutputStream();//enviar dados InputStream in = null; try { http = (HttpConnection) Connector.open(url); http.setRequestMethod(HttpConnection.GET); /*http.setRequestMethod(HttpConnection.POST); http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); //http.setRequestProperty("Conexão", "close"); String teste; byte dados[] = ("login=" + loginScreen.getUsername()).getBytes(); teste=new String(dados); out.write(dados); dados = ("&senha=" + loginScreen.getPassword()).getBytes(); teste=teste+new String(dados); out.write(dados); dados = ("&metodo=LOGIN").getBytes(); teste=teste+new String(dados); out.write(dados); out.flush();*/ //--------------TRATAR RESPOSTA DO SERVLET---------------------- in =http.openInputStream();//pegar resposta if (http.getResponseCode() == HttpConnection.HTTP_OK) { int length = (int) http.getLength(); String str; if (length != -1) {//tamanho da resposta conhecido byte data[] = new byte[length]; in.read(data); str = new String(data); } else {//tamanho não conhecido, deve ser pegar bit por bit até chegar ao final ByteArrayOutputStream aux = new ByteArrayOutputStream(); int ch; while ((ch = in.read()) != -1) { aux.write(ch); } str = new String(aux.toByteArray()); aux.close(); } if (str.equals("TRUE")) { set_boo(true); } else { set_boo(false); } } else { System.out.println(http.getResponseMessage()); } in.close(); http.close(); } catch (IOException e) { } }

Método utilizado POST “C/ PROBLEMAS”

private void verifica_Login() throws IOException { //String url = "http://localhost:8084/RKAM_ServLet/ServLet?"; //url = url + "login=" + loginScreen.getUsername() + "&senha=" + loginScreen.getPassword() + "&metodo=LOGIN"; String url = "http://localhost:8084/RKAM_ServLet/ServLet"; HttpConnection http = null; InputStream in = null; try { http = (HttpConnection) Connector.open(url); // http.setRequestMethod(HttpConnection.GET); http.setRequestMethod(HttpConnection.POST); http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); //http.setRequestProperty("Conexão", "close"); OutputStream out = http.openOutputStream();//enviar dados String teste; byte dados[] = ("login=" + loginScreen.getUsername()).getBytes(); teste=new String(dados); out.write(dados); dados = ("&senha=" + loginScreen.getPassword()).getBytes(); teste=teste+new String(dados); out.write(dados); dados = ("&metodo=LOGIN").getBytes(); teste=teste+new String(dados); out.write(dados); out.flush(); //--------------TRATAR RESPOSTA DO SERVLET---------------------- in =http.openInputStream();//pegar resposta if (http.getResponseCode() == HttpConnection.HTTP_OK) { int length = (int) http.getLength(); String str; if (length != -1) {//tamanho da resposta conhecido byte data[] = new byte[length]; in.read(data); str = new String(data); } else {//tamanho não conhecido, deve ser pegar bit por bit até chegar ao final ByteArrayOutputStream aux = new ByteArrayOutputStream(); int ch; while ((ch = in.read()) != -1) { aux.write(ch); } str = new String(aux.toByteArray()); aux.close(); } if (str.equals("TRUE")) { set_boo(true); } else { set_boo(false); } } else { System.out.println(http.getResponseMessage()); } in.close(); http.close(); } catch (IOException e) { } }

SERVLET

[code]public class ServLet extends HttpServlet {

private Connection c;
String metodo;


public void init() {
  conectar();
}

public void destroy() {
  desconectar();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    this.doPost(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    metodo = request.getParameter("metodo").toUpperCase();
    if (metodo.equals("LOGIN"))//login
    {
        login(request, response);
    }

    if (metodo.equals("CONSULTA")) {
        consulta(request, response);
    }

}

private void login(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    try {
        String senha = request.getParameter("senha").toUpperCase();
        String login = request.getParameter("login").toUpperCase();
        //conectar();
        ResultSet res = consultar("select * from login where login='" + login + "' and senha='" + senha + "'");
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        boolean aux = true;
        while (res.next()) {
            out.print("TRUE");
            aux = false;
        }
        if (aux) {
            out.print("FALSE");
        }
        out.close();
        //desconectar();
    } catch (SQLException ex) {
        Logger.getLogger(ServLet.class.getName()).log(Level.SEVERE, null, ex);
    }
}[/code]

O erro ocorre na linha 22 do SERVLET, no momento em que a variavel metodo na servlet recebe o parametro “metodo” passado, caso ele for passado por GET esta variavel recebe o parametro sem problemas, mas se foi passado pelo metodo POST, no momento que a variavel recebe o parametro a servlet fecha e exibe uma mensagem de erro “Internal servlet error”, assim nada é retornado para a midlet, creio que o problema esta na passagem dos dados pelo modo POST pela midlet caso seja isso como resolver?

Quando executo a servlet na saida tenho as seguintes mensagens

Alguem pode me confirma o código e me dar uma dica? Obrigado!!!
