Problem with Table.getSelectedColumn() method plz help its so urgent

Question

Hi,
I need to display a input msg box while the given icode( coloumn name) is not there in database and the the input value should goto the product( 3rd column in my table) column in table. my code is bellow.
private void TablePropertyChange(java.beans.PropertyChangeEvent evt) {
// ss
i=0;
int s=1;
String icde=new String();
String Prdct=new String();
String result=new String();
// String CODE=new String();
String ICDE=new String();
String prd=new String();
int Colselected=Table.getSelectedColumn();
//column.getPreferredWidth();
try
TableColumn ICode = Table.getColumnModel().getColumn(1);
TableColumn product = Table.getColumnModel().getColumn(2);
TableColumn unit = Table.getColumnModel().getColumn(3);
TableColumn rate = Table.getColumnModel().getColumn(4);
TableColumn Amount = Table.getColumnModel().getColumn(5);
for(;i<s;++i)
//For loop starts
ICode.setPreferredWidth(76);
product.setPreferredWidth(157);
unit.setPreferredWidth(75);
rate.setPreferredWidth(85);
Amount.setPreferredWidth(95);
Table.setValueAt(i+1,i,0);
float gr=0,//Gross amt
qt=0,//Qty
rt=0,//Rate;
dcp=0,//Disc%
dcam=0,//Disc Amt
edrt=0,//EDrate
edrt1=0,
edam=0,//EDGross
taxrt=0,//TaxRate
taxam=0,//TaxAmt
netam=0;//netamt
try
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
Connection con1 = DriverManager.getConnection(url1,"suresh", "special");
Statement stmt1 = con1.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
                    ResultSet.CONCUR_READ_ONLY);
Prdct=Table.getValueAt(i,1).toString();
Statement stmti= con1.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
                    ResultSet.CONCUR_READ_ONLY);
ResultSet rsi = stmti.executeQuery("select * from prd where ICODE='"+Prdct+"'");
java.util.Vector <String> prdct = new java.util.Vector <String>();
if(rsi.next())
String prodct=rsi.getString("ITEM");
prdct.add(prodct);
Table.setValueAt(prdct,i,1);
Double RT=rsi.getDouble("saleprice");
String RTS=RT.toString();
Table.setValueAt(RTS,i,4);
// int ColValue=Colselected==1;
else if(Colselected==1)
result = (String)JOptionPane.showInputDialog(this,
"Enter the new Item", "S-appsys's INFO",JOptionPane.INFORMATION_MESSAGE);
System.out.println("asdrf "+i);
Table.setValueAt(result,i,2);
// Colselected=0;
// Table.setV
// System.out.println("asdrf "+i);
}// Table.setValueAt(result,i,2);
}catch ( java.lang.ClassNotFoundException cl)
System.out.println("Error"+cl);
catch(java.sql.SQLException sq)
System.out.println("Error"+sq);
qt=Float.parseFloat(Table.getValueAt(i, 3).toString());
rt=Float.parseFloat(Table.getValueAt(i, 4).toString());
gr=qt*rt;
Table.setValueAt(gr,i,5);
s=Table.getRowCount();
}catch(java.lang.NullPointerException e){}

Your description of the problem makes no sense to me.
The code you posted in not formatted or executable so I'm not going to waste time trying to understand it.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.
