Help! Add Result into JTree or JList.

Question

Hi,
I retrived some values from one of the table from database using ResultSet. And I want to add
the result into the JList or JTree. Any help will be greatly appreciated.
Thanks in advance
Sam.
Here is the code.
void searchButton_actionPerformed(ActionEvent e) {
try{
String query = "SELECT * FROM PINFO WHERE POLICYNUMBER = '" +
searchTextfield.getText().toUpperCase() + "'";
ResultSet rs = Application1.stmt.executeQuery(query);
while(rs.next()){
pid = (rs.getInt("PID"));
System.out.println(pid);
catch(SQLException ex){
System.err.println("SQLException: " + ex.getMessage());
try{
String query = "SELECT * FROM (UNMATCH U LEFT JOIN DOCUMENTTYPE D ON U.DOCUMENTTYPE=D.DOCNUMBER) WHERE PID = '" + pid + "'";
ResultSet rs1 = Application1.stmt.executeQuery(query);
while (rs1.next()){
String documentcode = (rs1.getString("DOCUMENTCODE"));
//************** I want to add these documentcode into the Jlist or jTree.
System.out.println(documentcode);
catch(SQLException s){
System.err.println("SQLException: " + s.getMessage());
}

public class blah
Vector v;
JList j;
public blah()
v = new Vector();
j = new JList(v);
JPanel jP = new JPanel();
jP.add(j);
public getResults()
v.removeAllElements();
j.setListData(v);
String query......
Resultset rs = .....
while(rs.next())
String s = rs.getString("");
v.add(s);
j.setListData(v);
