I am able to connect Oracle19 db instance using SQL developer
hostname-localhost
port-1521
servicename- xepdb1
----
I am writing a simple java class - ConnOracle which connects with oracle db and fetch few information.
import java.sql.*;
class ConnOracle{
public static void main(String args[]){
try{
//step1 load the driver class
Class.forName("oracle.jdbc.driver.OracleDriver");
//step2 create the connection object
Connection con=DriverManager.getConnection(
"jdbc:oracle:thin:@//localhost:1521/xepdb1","username","MyPassword");
System.out.println(".. created the connection object..");
//step3 create the statement object
Statement stmt=con.createStatement();
//step4 execute query
ResultSet rs=stmt.executeQuery("select * from accounts");
while(rs.next())
System.out.println(rs.getInt(1)+" "+rs.getString(2));
//step5 close the connection object
con.close();
}catch(Exception e){ System.out.println(e);}
}
}
The program is failing at line
Connection con=DriverManager.getConnection(
"jdbc:oracle:thin:@//localhost:1521/xepdb1","username","MyPassword");
java.sql.SQLException: ORA-01017: invalid username/password; logon denied
