//import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Wrapper;
public class DoConnect {
public Wrapper DoConnect(String drv, String url, String uid, String pss){
try {
Class.forName(drv);
System.out.println("Driver class found");
} catch (ClassNotFoundException err) {
System.out.println(err);
}
try {
System.out.println("Connected...");
return DriverManager.getConnection(url, uid, pss);
} catch (SQLException err) {
System.out.println(err);
}
return null;
}
public static void main(String[] args) {
DoConnect ocon= new DoConnect();
ocon.DoConnect("oracle.jdbc.driver.OracleDriver", "jdbc:oracle:thin:@10.10.15.16:1521:lems", "scott", "tiger");
}
