java.sql.SQLException: ORA-01005: null password given; logon denied

I’m getting the follwing exception while trying to connect to a database:

java.sql.SQLException: ORA-01005: null password given; logon denied

        at com.alting.med.Main.main(Main.java:252)

here the method used to get the connection:

private Connection getConnection(String url, String driverClass, String user, String password) throws ManagerDBException 
{
    try
    {
        Class.forName(driverClass);
    } catch (ClassNotFoundException e) {
        throw new ManagerDBException(e.getMessage());
    }

    try
    {
      this.connection = DriverManager.getConnection(url, user, password);
    }
    catch (SQLException e)
    {
      throw new ManagerDBException(e.getMessage());
    }
    return this.connection;
}

But even when the params (url, password..) are hardcoded, I still get the exception.

Could you tell me how to fix this problem ? thanks

Answer

it appears the problem is linked to the “-Djava.endorsed.dirs” parameter from the java startup command line.

By removing this one, everything goes well.
