Amigos estou desenvolvendo um projeto da seguinte forma
.JSP, .JS E .HTM -> CAMADA DE APRESENTAÇÃO
.JAVA ->CAMADA DE NEGÓCIO E DE PERSISTÊNCIA
SGBD -> ORACLE 9i
Quando tento me conectar com o Banco(que está num servidor da rede) ele me retorna esse erro:
Erro ao tentar se conectar ao banco
java.sql.SQLException: Exceção de E/S: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153092352)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))

O meu .java de conexão é esse:
private static final String driverName = "oracle.jdbc.OracleDriver";
public static Connection conexao = null;
public static Statement statement = null;
private static String serverName = "servdesenv:1521:sigecon";
private static String usuario = "sigecon";
private static String senha = "sigeconsql";
private static String url = "jdbc:oracle:thin:@" + serverName;
public static void abrirConexao() throws SQLException, Exception {
try {
if (conexao == null) {
Class.forName(driverName);
// DriverManager.registerDriver(new OracleDriver());
conexao = DriverManager.getConnection(url, usuario, senha);
statement = conexao.createStatement();
System.out.println("Conexão aberta!");
} else {
System.out.println("Conexão já se encontra aberta!");
new SQLException("Erro SQL ao criar a conexao");
}
}
catch (SQLException e1) {
System.out.println("Erro ao tentar se conectar ao banco");
e1.printStackTrace();
} catch (Exception e2) {
System.out.println("Erro Geral ao abrir conexao");
e2.printStackTrace();
}
}
Bem, quem puder me ajudar, agradeço desde já e até mais!
