Populate JComboBox from a database...i'm new!

Question

I want to populate a JComboBox from a Database. I have my query set up and I have seen people's solutions that look like this:
JComboBox CbTeamName = JComboBox();
try{
//Register Driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//Get Connection
conn = DriverManager.getConnection("jdbc:odbc:SLeague", "", "");
System.out.println("Connect Database succesfully");
//Create SQL Statement
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT teamName FROM teamInfo");
while(rs.next()){
CbTeamName.addItem(rs.getString("teamName"));
stmt.close(); //Close the SQL Statement
conn.close(); //Close the connection of Database
System.out.println("Connection close");
catch(SQLException sqlex) {
System.out.println(sqlex);
catch(Exception ex) {
System.out.println(ex);
However, I have a problem in that my database connection is in another class (which is in another package). I added this line of code into my class, which has my connection in it:
DataAccess.AppointmentDA.initialize();
Basically I can't figure where to put what code. I don't even know if I am explaining this correctly, but its 1AM and I am frustrated. If you think you can help me I would GREATLY appreciate it.

Hi,
In the class where you have your database code,add a new method
Vector getTeamNames()
Vector teamNames;
rs = stmt.executeQuery("SELECT teamName FROM teamInfo");
while(rs.next()){
teamNames.addElement(rs.getString("teamName"));
stmt.close();
return teamNames;
In the place where you need to add this in combo you can have the following code :
Vector teamNames=db.getTeamNames();
for(int i=0;i<teamNames.size();i++){
CbTeamName.addItem(teamNames.elementAt(i));
So you can maintain the database part and view part in seperate classes/packages.
Hope this helps,
