Cant get data from text file to print into Jtable

Question

Instead of doing JDBC i am using text file as database. I cant get data from text file to print into JTable when i click find button. Goal is to find a record and print that record only, but for now i am trying to print all the records. Once i get that i will change my code to search desired record and print it. when i click the find button nothing happens. Can you please take a look at my code, dbTest() method. thanks.
void dbTest() {
DataInputStream dis = null;
String dbRecord = null;
String hold;
try {
File f = new File("customer.txt");
FileInputStream fis = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
Vector dataVector = new Vector();
Vector headVector = new Vector(2);
Vector row = new Vector();
// read the record of the text database
while ( (dbRecord = dis.readLine()) != null) {
StringTokenizer st = new StringTokenizer(dbRecord, ",");
while (st.hasMoreTokens()) {
row.addElement(st.nextToken());
System.out.println("Inside nested loop: " + row);
System.out.println("inside loop: " + row);
dataVector.addElement(row);
System.out.println("outside loop: " + row);
headVector.addElement("Title");
headVector.addElement("Type");
dataTable = new JTable(dataVector, headVector);
dataTableScrollPane.setViewportView(dataTable);
} catch (IOException e) {
// catch io errors from FileInputStream or readLine()
System.out.println("Uh oh, got an IOException error!" + e.getMessage());
} finally {
// if the file opened okay, make sure we close it
if (dis != null) {
try {
dis.close();
} catch (IOException ioe) {
} // end if
} // end finally
} // end dbTest

Here's a thread that loads a text file into a JTable:

And my reply in this thread shows how you can use a text file as a simple database:
