Pessoal, estou tendo problemas ao tentar fazer uma conexão com o bd
Oracle.
Estou tentando fazer esta conexão com um programa simples:
import java.sql.*;
class jdbc_test {
public static void main (String args []) throws SQLException {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn =DriverManager.getConnection
("jdbc:oracle:thin:@amazonia:1521:orcl","scott@lacta","tiger");
Statement stmt = conn.createStatement ();
ResultSet rset = stmt.executeQuery("select ename from emp");
while (rset.next ())
System.out.println (rset.getString (1));
}
}
E os erros são estes:
Exception in thread "main" java.sql.SQLException: Exceção de I/O:
Connection
refused(DESCRIPTION=(TMP=)(VSNNUM=135286784)(ERR=12505)(ERROR_STACK=(ERR
OR=(CODE=12505)(EMFI=4))))

Já agradecido pela atenção !
