Adding database elements to a list box?

[StephNicolaou]

Hi developers,
I'm not sure if this is possible, but I've tried to add database elements to a list box.
There are no errors shown, but it simply does not work. Here is the code below:

if(criteria1 == 1){
getDBConnection();
try 
{

    stmt = conn.createStatement();

    if(stmt.execute("SELECT Clients.Firstname FROM Clients WHERE Clients.Firstname= '"+ searchCriteria1 + "' "))
    {

	rs = stmt.getResultSet();
	System.out.print("STEP 2");

    }

	while(rs.next()) {
	//Add to record List box

	searchListModel.addElement(rs.getString(1).trim());
	System.out.print("STEP 3");

	}

}

catch (SQLException ex) {

    System.out.println("SQLException: " + ex.getMessage());

    return;

}

statements, listbox, listmodel and criteria and all been previously initialised.
Thanks in advance,
Cleo

Have verified your query is returning results? Have you set the list model on the JList?

I've tested the statement edited below in mySql and it does return the record I expect. Althout when I try to print out to the terminal, it only gets up to the print out 'STEP 2' :

if(event.getSource() == search) { //if search button is clicked
   System.out.print("STEP 1");
  System.out.print("criteria" + criteria1);

if(chosenCriteria1.equals(search1)) { 
//search 1 = firstname //search string
//chosenCriteria1 = firstname // (from combobox)
	criteria1 = 1;
	System.out.println("criteria 1: hellooooooo:" +criteria1);
}

if(criteria1 == 1){
getDBConnection();
try {
stmt = conn.createStatement();
if(stmt.execute("SELECT Firstname FROM Clients WHERE Firstname = '"+ searchCriteria1 + "' "))
{
  rs = stmt.getResultSet();
  System.out.print("STEP 2");
}
while(rs.next()) {
	String name = rs.getString("Firstname");
                System.out.println("name :" + name);

	//Add to record List box
	searchListModel.addElement(rs.getString(1).trim());
						System.out.print("STEP 3");
}
}
catch (SQLException ex) {
	System.out.println("SQLException: " + ex.getMessage());
	return;
}

And I have added the model to the list :

searchListModel = new DefaultListModel();
searchListModel.addElement("TEST");
searchList = new JList(searchListModel);

"Test" is currently seen in the list box...
