Multiple database access

Question

Hi there!
I'm having problems with connection to my databases. The idea is:
-step 1. Check if a number exists in database A (connect A-->query-->close A)
-if the number does exist, do nothing
-step 2 else, open database B and,
-step 3 copy the record of the particular number to database A (connect B-->query-->close B --> connect A --> query --> close A)
Now the problem is that somehow the database url stays the same (URL of db A), and so I cannot connect to database B.
This is my db connection method, which I call from another class. As you can see, i've put up some println's to see where the error pop's up, but it makes absolutely no sense.
public void openConnection(String database, String username, String password)
               try     {
                    String url = new String("jdbc:mysql://" + database);
                    Class.forName("com.mysql.jdbc.Driver");
                    System.out.println("Opening database "+url +" with credentials: "+username+ " AND password: "+password);
                    connection = DriverManager.getConnection(url, username, password);
                    System.out.println("Connection opened");
               } catch( ClassNotFoundException e) {
               System.out.println("JDBC Error:");
               e.printStackTrace();
               catch ( java.sql.SQLException e ) {
               System.err.println("SQL Exception:");
               e.printStackTrace();
     }Now the following output/error occurs:
(step 1)Opening database jdbc:mysql://localhost/sms with credentials: blaat AND password: blaat
Connection opened(step 2)Opening database jdbc:mysql://otherhost/users with credentials: blaat1 AND password: blaat1
SQL Exception:
java.sql.SQLException: Access denied for user 'blaat1'@'localhost' (using password: YES)(step 3)Opening database jdbc:mysql://localhost/sms with credentials: blaat AND password: blaat
Connection openedAnyone?!

Then I call openconnection with database address "otherhost" (which it DOES display in the System.out.prinln) but the connection fails, and when you look in the errorlog you can see that it still tried to connect to "localhost"..?!??!As a guess you are reading more into that error message that what it says.
The error can only occur if it is in fact connecting to a database. So at a minimum if you stopped the local server then you can insure that it is not doing that. But as a guess I would suppose 'localhost' in the error message is meaningless. As noted in the previous post it is just telling you that the log in failed.
