I'm using Oracle 11g and have set ojdbc6.jar in my classpath. And when I am trying to connect with database with the following code:
//JdbcTest.java
import java.sql.*;
public class JdbcTest
{
public static void main(String args[])throws Exception
{
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","scott","tiger");
Statement st=con.createStatement();
ResultSet rs = st.executeQuery("select * from dept");
while(rs.next())
{
System.out.println(rs.getInt(1)+ " " + rs.getString(2) + " " + rs.getString(3));
}
rs.close();
st.close();
con.close();
}
}`
I am getting the following error:
Exception in thread "main" java.sql.SQLException: Listener refused the connection with the following error:
