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();

} 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
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);
}
}
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 mensagensUsing CATALINA_BASE: C:\Documents and Settings\Administrador\.netbeans\6.0\apache-tomcat-6.0.14_base

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