Problem with updating database

Question

Hi, gurus. here is the snippet of my program, dont know why it doesnt work properly.
//this the first java bean, storing user's form inputs
public class FirstPageBean
  private String userName;
  private String docType;
  private int index;
  public FirstPageBean()
       userName = "admin";
       docType = "book";
       index = 0;
  public void setUserName(String name) {userName = name;}
  public String getUserName(){userName = userName.trim(); return userName;}
  public void setDocType(String docType){this.docType = docType;}
  public String getDocType(){docType = docType.trim(); return docType;}
  public void setIndex(int index){this.index = index;}
  public int getIndex(){index = index.trim(); return index;}
//the second java bean is basically the same fashion as the first one.
The problem is in the following sinppet of the third java bean.
Instead of instoring the user's inputs into a table in my database,
what i actually get from this entries are all their default values,
like "admin" for userName, "book" for docType etc. The first and
second bean have been tested and they successfully instored user's
inputs into their conresponding properties. But i just cant figure
out why these values are not successfully retrived from the
ControllerBean.
public class ControllerBean
   //blah blah....
   public void update(){
   String userName = new FirstPageBean().getUserName();
   String docType = new FirstPageBean().getDocType();
   int index = new FirstPageBean().getIndex();
   Connection conn = connect();
   PreparedStatement stat = conn.prepareStatement("insert into movie values (?,?,?)");
                stat.setString(1, userName);
                stat.setInt(2, index);
                stat.setString(3, docType);
   stat.executeUpdate();
}Any help would be deeply appreciated. thanx in advance.

Wherever it is that you accept input from the user for the three values, assign them to the three fields you use for the SQL statement.
If you really want to use the getXxx and setXxx methods, instantiate a single FirstPageBean and use the setXxx methods.
FirstPageBean FPB = new FirstPageBean();
FPB.setUserName( userNameFromInput );
FPB.setDocType( docTypeFromInput );
FBP.setIndex( indexFromInput);
Connection conn = connect();  
PreparedStatement stat = conn.prepareStatement("insert into movie values (?,?,?)");               
stat.setString(1, FPB.getUserName);               
stat.setInt(2, FPB.getIndex);               
stat.setString(3, FPB.getDocType);  
stat.executeUpdate();I haven't compiled this but you should get the idea.
