Question

I dev a class to implement Connector

import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;
import oracle.toplink.sessions.Connector;
public class Class1 implements Connector{
public Connection connect(Properties properties) {
Connection conn = null;
try {
DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection
("jdbc:oracle:thin:@****:1521:***", "***", "****");
} catch (SQLException e) {
// TODO
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO
return conn;
public void toString(PrintWriter printWriter) {
public String getConnectionDetails() {
return "gaojun test";
public java.lang.Object clone(){
return this;
public static void main(String args[]){
new Class1().connect(null);
and then what to do?
I do not want to use session.xml,but need to config dbmapping.xml to define queries.
Please give help

Not sure why you are trying to implement your own Connector. To connect to Oracle JDBC just your login's connectionString and driverClass.
If for some reason you need a custom connector, then just set your instance in the Session's DatabaseLogin.
