NumberFormat Exception

I have no idea why I am getting this error. It is kind of freaky because sometimes it appears and other times it doesn't. This is the piece of code it is coming from:
for (int w = 0; w <= pm-pf; w++) {
   jTable4.setValueAt("Survey", new Integer(SelectionList.get(w).toString()).intValue(), 6);
   jTable4.setValueAt("Survey", new Integer(SelectionList.get(w).toString()).intValue(), 8);
   Double surveyvalue = new Double(jTable4.getValueAt(new Integer(SelectionList.get(w).toString()).intValue(),3).toString());
   jTable4.setValueAt(surveyvalue,new Integer(SelectionList.get(w).toString()).intValue(),5);
   jTable4.setValueAt(jTable4.getValueAt(new Integer(SelectionList.get(w).toString()).intValue(),4),new Integer(SelectionList.get(w).toString()).intValue(),7);
}The error is on this line:
   jTable4.setValueAt(surveyvalue,new Integer(SelectionList.get(w).toString()).intValue(),5);When I test out this line:
jTable4.setValueAt(new Double(-0.1801),4,5);It works just fine. The value of surveyvalue is:
-0.1805
so I don't understand why I am getting this error:

Now, if I put a System.out.println(); in before the setValueAt, it works. I am banging my head against the wall.
Any ideas?
Thanks.

Here is my table model:
class MyFTableModel extends DefaultTableModel {
    public Class getColumnClass(int c) {
      return getValueAt(0, c).getClass();
    public MyFTableModel(Vector columnNames, int numRows)
      super(columnNames, numRows);
    public boolean isCellEditable(int row, int column) {
      return false;
}Is this the reason why?
Thanks.

Help with New NumberFormat Exception

Hello. I'm new to java and I can't figure this out. I'm trying to prevent customers from entering a negative value for the quantity or price with a (quantity <= 0)New NumberFormat Exception but it's not working. The negative values are being calculated in the grand total giving impossible results. -$4.50 can't be. How can I fix this problem?
Is this the right forum for my question? If its not, please move this away.

I suggest changing your code slightly. In the actionPerformed() method when you are calling other methods to parse the input, use a try/catch block around those methods. Something like thispublic void actionPerformed(ActionEvent e) {
          if(e.getSource() == calcButton) {
               try {
                    Title = txtTitle.getText();
                    Author = txtAuthor.getText();
                    quantity = getQuant();
                    price = getPrice();
                    transCount();
                    lastTot();
                    numBooks();
                    subTotal();
                    salesTax = salesTax();
                    shipping = shipping();
                    total = total();
                    answer = outFormat();
               } catch(NumberFormatException ne) {
          } else {
               //resetButton should clear all the fields.
     }Then, inside the methods that parse the data, change the code so the exception is thrown to the caller, something like this     //Prevent user from entering invalid quanity numbers.
     public int getQuant() {
          boolean error = false;
          try {
               quantity = Integer.parseInt(txtQuantity.getText());
          } catch(NumberFormatException ne) {
               error = true;
          error = error | quantity <= 0;
          if (error) {
               statusArea.setText("Please enter a valid number for quantity.");
               throw new NumberFormatException();
          return quantity;
     }This allows the error to cause the program to skip calculating.
I also think you have a logic problem with how you are calculating shipping.

Handling Consecutive NumberFormat Exceptions

I have written a Binary Search Program for which I am asking the user to enter the size and the elements of the array.
If the user enters the size say 5
Now he can enter up to a max of 5 max numbers to populate the array.
If the user enters an alphabet it should not be accepted and it would throw an exception and its caught properly for the first time and the user is asked to enter the number again. Now again if the user enters an alphabet my program is not robust enuf to throw an error to the user and continue the user to enter a number from that point. How do i handle such exceptional conditions.
import java.util.Arrays;
import javax.swing.JOptionPane;
public class BinarySearch {
     public static void main(String[] args) {

Java.lang.numberformat exception

Hi,
I have a situation wherein i am trying to assign a integer parameter value (coming from a SQL Server Stored Procedure) into an int variable in the program and i am getting the above exception.
The data format is same in the sense, incoming parameter can have a possible value of 0 or 1 or 2. The local variable in the program is initliazed to 3.
Please let me know if you have a solution.
Regards
Ramesh

What is the line of code causing the Exception? What is the datatype that the stp returns and what is the datatype of the column in the db?

This URL is the Agent Dashboard you are talking about, this page cannot be used to Create SR, in this the agent can only view SRs in his queue.
No patch would be there from Oracle which makes SR flow in OAF, this is a CRM module and is built on JTF fwk using AK dictionary.
For CS, few setups screens have been converted into OA pages in 11.5.10, these were forms in 11.5.9, for example the req type-resp mapping screen.

Numberformat exception, xdk bug ????

Hi,

oracle.xml.sql.OracleXMLSQLException: 'java.lang.NumberFormatException: 5.2' encountered during processing ROW element 0. All prior XML row changes were rolled back. in the XML document.
i want to ask whether this is a bug of the xdk !!!
i am using :
jdbc - classes111.zip
xdk version - xdk_java_9_0_2_0_0B
can anybody HELP me ???
i tried to fix it using 3 days already !!!
Thanks

Same problem wth the 90110a XDK release for plsql on unix and win. An earlier version of this worked (we were on whatever version shipped with Oracle 8.1.7 near the beginning of this year). Bug workaround is to create views of your base tables making all of your numeric columns into character columns (to_char(col_name) ) and then to write instead-of triggers on the views to insert the data to the target table. When will this be fixed or is this the way it will work from now on?

Throwing NumberFormat exception

iam using this code but it is throwing NumberFormatException can anybody help thanks in advance.
int p_in_size=Integer.parseInt(request.getParameter("p_init_size"));

"p_init_size" is either the wrong name or it contains non-numeric data.
Try printing out request.getParameter("p_init_size") before the parseInt to see what data it is actually getting.

Exception already caught

when i try to compile this code it tells me NumberFormat Exception has already been caught, but this is the only try/catch statement in the program... why is this?
                         try
                              //make the new automata
                              automaton = new CellularAutomaton(neighbors,depth,base,Integer.valueOf(rule.getText()).intValue(),states);
                              timer.start();
                              goButton.setText("Stop");
                              status.setText(" ");
                         catch(IllegalArgumentException e1)
                              status.setText("Invalid decimal number");
                         catch(NumberFormatException e2)
                              status.setText("Invalid decimal number");
                         }

If you want. It just depends on what you want your program to do. You may want one behavior if there's a NumberFormatException and something else for an IllegalArgumentException. If not, IllegalArgumentException will catch NumberFormatException...
Hope this helps!

How to Increase size of order no field in the existing acc registration?

Hello All,
My question is How can I increase the size of the Order number field in 'Need online access to your existing account regisrtation' form?
In the B2B registration process of a user of an existing account.
When a user clicks on 'Need online access to your existing corporate account?'
The following form appears with 3 fields Account number, Order Number and Order Date along with username, password and email fields.
The order number field is only 10 characters. We need the ability to enter order number with 11-12 characters . Can you please describe the changes that need to happen?
Do we need to modify the ibeCRgdBusinessCreatePartial directly?
I have modified this jsp but I get a java.lang.numberformat exception whenver I try to input more than 10 characters.
I will be very grateful if you can help.
Many Thanks
SR
Edited by: user624059 on 23-Jun-2011 06:18

Thank you for replying to my question...
Raised an SR,l it needs a change in ibeCRgdBusinessCreatePartial.jsp & ibeCRgpBusinessCreatePartial.jsp.

Error in retrieving value from the inputfield.

Hi Experts,
There is this behaviour I saw in WD which was understood by me.
Let me explain it :
I am doing a comparison scenario where I compare 2 products in a grid format.
For this I have a table with a various types of variants.
In this grid I have a inputfield which takes an integer input and based on which there is an effect on other variant field of that product.
Now I am retriving the value of the input field in the modify view through
input.getValue(); parse this string to an Integer and then pass it to the model.
Here is the problem everything works fine when the user goes and changes the value for the firsttime but if he does the same thing without the input field loosing focus it throws a Numberformat exception this occurs because the string value retrived this time is an empty string which obviously can't be parsed.
Can anyone explain me the why is it behaving in this way?
Any help will be truly appriciated.
Best Regards & Thanks in Advance
Amit

Hi,
If u want to change the focus before retrieving the data from input field, try
IWDButton b=(IWDButton)view.getElement("Button");
b.requestFocus();
before
IWDInputField in1=(IWDInputField)view.getElement("InputField2");
int a=Integer.parseInt(in1.getValue());

Problem retreving datetime

hi
how to retrieve datetime with result;
if i use rs.getDate("CREATE_DATE") i am getting numberformat exception?i am using oracle database?
i want in this format 12-Jul-2003 14:20 format???
can anybody give me code
SELECT TO_CHAR(CREATE_DATE, 'DD-MON-YYYY HH24:MI') AS CREATE_DATE FROM COMPLAINT_DETAILS A,COMPLAINT_MASTER B, OFFICE_HIRARCHY C,CONSUMER_MASTER D,USER_MASTER E WHERE RECORD_STATUS='ACTIVE'

Remove the TO_CHAR() in your sql string. Else it just return a String but not a Date then cause the NumberFormat exception.

Help me

I'm trying to create configure for JDE XE and 8.11 for Oracle AS for the integration with FMW. I finished configuring the JDE adapter, but while connecting JDE instances getting error in Application Explorer like, NumberFormat Exception as displayed in the question above.
Can anyone tell please tell me where exactly I need to copy these .jar files from the JDE 8.11 as well as JDE XE. Actually I asked my JDE team to provide jar files to cinfigure the adapters and they are saying like they have multiple .jar files available across the folders.I have gone thru the docs but not sure where exactly the files to be copied. If I use different version the error changes to ArrayIndexOutOfBoundsException 0 > 0.
For JDE XE connector.jar and kernel.jar
and for 8.11 additional jdeutil.jar and log4j.jar.
Please let me know where exactly the files to be copied.
Thanks,
Nirav

Invalid value

Hi,
I have the following actionListener with a numberformat exception, when an invalid value is entered into the textfield the exception is thrown but the program still takes the number an repaints the graphics. How do I make the program not do anything when an invalid number is entered.
can anyone help?
cheers
void jTextField5_actionPerformed(ActionEvent e) {
    Float tempf = Float.valueOf(jTextField5.getText());
    f = tempf.floatValue();
    NumberFormatException df_g0_exception = new NumberFormatException("Invalid value");
    try
if(Float.parseFloat(jTextField5.getText()) < 0)
        throw df_g0_exception;
if(Float.parseFloat(jTextField5.getText()) > 100)
        throw df_g0_exception;
    catch(NumberFormatException nfex)
      //Error message if a number forma exception has occured
      JOptionPane.showMessageDialog(this,"enter number between 0 and 100","Number format exception",JOptionPane.WARNING_MESSAGE);
    calc();
    can.repaint();
}

You must do everything in the TRY statement. Thus calc(); and can.repaint(); must be called in the try. If a problem occurs the JVM gets out the Try and goes to the corresponding catch statement. In that case, the GUI is not refreshed.
Try that!
Hope it helps,
