JTable error!!!

Guys,
I got the code below compiled, but it does not run. I wanna start the JTable depending on a integer value. I have a runtime error. I placed it in the bottom...
//stackSize is defined before, and it's value is ok.
public class Pilha extends JFrame implements ActionListener
public String[][] data;
public int StackSize;
public Pilha()
if (stackSize ==3 )
{ String[][] data = {{""}, {""}, {""}}; }
String[] go = {"Stack"};
JTable table = new JTable(data,go);

All right, I tried it, but what I got:
Pilha.java:82: illegal start of expression
{ data = {{""}, {""}, {""}}; }
Put in other words, if I just declare data outside method Pilha() as public and inside Pilha() I try to assing a value to data, It does not work.
Can you help me?

JTable Error When Editing

I have a JTable that is created by a ResultSetTableModel class as shown below. I have written code to insert, delete, update, and reset the the rows in this table, which then updates a database. However, when the table is in editing mode, and i hit enter or tab, i receive the following error:

Nevermind...I figured it out. Just had to override the setValueAt function for the ResultSetTableModel.

Still cant get it to work ?????? jTable Error

Hi All,
not to sure how to put the problem but here goes
i have been working on a problem using a JTable
and MYSQL database and the information is coming
up twice. i am using abstractTableModel.
i am just wondering if there is something a have over looked
if any one can help me it will Much appreciated
JJ

and the information is coming up twice.
Then you are adding the information to the TableModel twice.
i am using abstractTableModel. No you aren't. You are using some class that extend AbstractTableModel. I would suggest you use the DefaultTableModel so you don't have to write your own TableModel.
Simple example:

Hi,
in this case the bind variable name comes from the viewLink definition. What is the m/d, is it based on e.g. Departments/Employees pushing the ADF BC wizard? I need to understand how to build a testcase that allows me to reproduce the issue. Do you show both , master and detail on the Swing form, or only the detail?

Edited by: YellowMurdoch on Nov 17, 2009 6:31 AM

Thanks for noting that.
you mean like this?
public void addEntry(TableData data){
        myTableModel.addRow(data);
        javax.swing.SwingUtilities.invokeLater(new Runnable(){
            @Override
            public void run(){
                    myTableModel.fireTableRowsInserted(0,0);
    }both work,
would putting "invokeLater" inside "addEntry" somehow mess other things?
i guess that means addRow() is not supposed to update the table graphically?

Error while updating JTable

WHAT I WANT TO DO:
I display a list of items and their characteristics in a JTable (the content is in a DefaultTableModel). Each time a user buys items, I refresh the list for all the users currently connected to the server. The client buying the item is also prompted through a JOptionPane that his order has been processed.
THE CODE:
controller.handleOrder();
JOptionPane.showMessageDialog(new JFrame(), message, "SUCCESSFUL ORDER", JOptionPane.INFORMATION_MESSAGE);Another thread calls the following function, which refreshes the list in the JTable:
public void updateFlowers(){
     // method in Controller
     setChanged();
     notifyObservers();
    |
    V
public void update(Observable arg0, Object arg1) {
     // method in Frame
     loadFlowers();
    |
    V
private void loadFlowers(){
     // method in Frame
     flowerTableModel = controller.loadFlowers();
     flowerTable.setModel(flowerTableModel);
   |
   V
public DefaultTableModel loadFlowers() {
     // method in Controller
     Object table[][]=null;
     flowers=ClientOperations.getInstance().getFlowers();
     if (flowers!=null){
          table=new Object[flowers.size()][3];
          int i=0;
          for (Flower flower:flowers){

Updating of Swing components must be done on the EDT. Wrap the code in SwingUtilities.invokeLater() or use a SwingWorker.
Read the section from the Swing tutorial on Concurrency for more information.

Runtime Error in JTable with JTableModel Implementation

Hi,
I tried to do a JTable (named "table) in my program, with an implementation of JTableModel, called DataContent (obj named "dc"). Now if I try to change dc's data and refresh the table in the window by doing a "table.setModel(dc);", my programm gives me just runtime errors.
class MyFrame extends JFrame implements ActionListener{
// This is the class of the JFrame which contains the table
// globally defined vars:
private DataContent dc;
private final JTable table;
// in someMethod(){
public MyFrame(){
// creates, inits and draws the table into the window - this works !
     JPanel jpPreview = new JPanel(new GridLayout(1,0));
     dc = new DataContent();
        table = new JTable(dc.getTableData(), dc.getCol());
        table.setPreferredScrollableViewportSize(new Dimension(500, 40));
        table.setBorder(borderPanel);
        jpPreview.add(table);
     jpSeparator.add(jpPreview);
public void actionPerformed(ActionEvent ae) {
// in the same class
          if(ae.getSource() == butLoadPath){
               // choose a path by clicking on a button "butLoadPath"
               szPath = sg.readPath();
               labelLoadPath.setText(szPath);
               dc.setPath(szPath);
               dc.setContent(szToken);
          }else if(ae.getSource() == butSeparator){
               // choose a different separator token by JRadioButtons
               // when someone clicks on the button butSeparator,
               // the table should be refreshed, with this function:
               setPreview();
          }else...
private void setPreview(){
          // reads out which option was chosen by the radiobuttons - this works
          // refreshes the Object[][] oData in dc - this works, too
          dc.setContent(szToken);
          // this should refresh the table obj in the JFrame,
          // this gives me some Null.pointer.exception - why ?
          table.setModel(dc);// ??? P R O B L E M ???
     }I have implemented the Interface DataContent like this:
public class DataContent implements TableModel{
     // vars
     private int iRow,iCol;
     private String szInputData = "";
     char cToken, cLineLimiter;
     private Object[][] oData;
     // ctor
     public DataContent(){
          reset(); // set Elements...
     public void setPath( String szPath){
          // read line from file obj...
     private void reset(){
          // set up an epmty set of data in the table...
     public void setContent( String szToken){
          // separate content of szInputData by szToken and set oData...
     public Object[][] getTableData(){
          // return oData...
     public String[] getCol(){
          // gives some name for each column...

...works without probs ???
Is there a better way to do this - the table should not even be editable, just to be shown in the window, to give an impression ??
THX

Why are you creating you own TableModel. Use the DefaultTableModel its easier. If you don't want you cells to be editable then you just do this:
JTable table = new JTable(...)
     public boolean isCellEditable(int row, int column)
          return false;
};

Reporting errors while filling a JTable

Hello all, this is my first post here.
When i implement a class derived from AbstractTableModel to show some data in a JTable, sometimes, specially when this data is coming from databases, i need to be able to report any errors that ocur while geting that data via a message dialog, for example, specifically inside the overriden getValueAt() function, eg.
public Object getValueAt(int rowIndex, int columnIndex) {
try{
..... read the information from the database
}catch(SQLException ex){
JOptionPane.showMessageDialog(null, "Error!"........ show the error
this actually works, the message dialog is shown if an error ocurs, however there are 2 problems:
1.- after the user closes the message dialog, the JTable is not painted properly.
2.- i get all these exceptions:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

If i just remove the line that shows the message dialog, then everything works ok. But i NEED a way to inform the user that something went wrong, how do i do this?
Thanks!

Hey numbnuts,
People keep reporting this error and you keep closing it w/o proper attention:
In SwingUtilities, sometimes "dest" becomes null. Don't tell why - sometimes its because of some library maybe you didnt write. But if you put in a "*if (dest == null) o something ...*" in there - it would fix it. Even a freshman comp sci programmer knows that.
And you wonder why nobody wants to learn Java anymore...
    public static Rectangle computeIntersection(int x,int y,int width,int height,Rectangle dest) {
        int x1 = (x > dest.x) ? x : dest.x;
        int x2 = ((x+width) < (dest.x + dest.width)) ? (x+width) : (dest.x + dest.width);
        int y1 = (y > dest.y) ? y : dest.y;
        int y2 = ((y + height) < (dest.y + dest.height) ? (y+height) : (dest.y + dest.height));
        dest.x = x1;
        dest.y = y1;
        dest.width = x2 - x1;
        dest.height = y2 - y1;
     // If rectangles don't intersect, return zero'd intersection.
     if (dest.width < 0 || dest.height < 0) {
         dest.x = dest.y = dest.width = dest.height = 0;
        return dest;
    }End Communication

JTable Print to Adobe Acrobat Error

I'm having trouble printing a jTable using Java 1.5.0_03 to Adobe Acrobat (6.0). Whenever I call print using (assuming proper try/catch statements) either
jTable.print();or
printJob.setPrintable(jTable.getPrintable(JTable.PrintMode.FIT_WIDTH, new MessageFormat("Header"), new MessageFormat("Footer")));
if (printJob.printDialog())
printJob.print();the printed jTable's column headers extend higher than they are supposed to like they were stretched (like when you drag the scroll bar down on your screen and the screen freezes), and effectively cover up parts of the header (the "Header" in this case).
My jTable is setup as follows
XYZ = new DefaultTableModel();
XYZ.addColumn("A");
XYZ.addColumn("B");
jTable = new JTable();
jTable.setModel(XYZ);I think this is an error with how the print function interacts with Adobe Acrobat as I don't have this problem printing to a normal printer. Is there any way to fix this?

Are you saying there is no Adobe PDF printer, or it does not work? If it simply that it does not seem to work, then try to print to file with the printer. Then open the file in Distiller. If you get a resultant PDF, then the problem is most likely that you have somehow deactivated AcroTray.exe in the running applications. The program is in the Acrobat folder and needs to be started in that case. It should also be listed in your boot sequence for startup.

Error mouse click header on jtable

I have a small project. I use jtable, i wrote class MymodelTable for jtable (include event mouseclicked).
On jtable, i can click on header to sort.
But, when i click button search a string (get from textfield), i was be error ...
Please help me resolve my error. (I attached my project in path: http://www.mediafire.com/?u4nw7uajdxrg97h )
Thanks

With a call to getSelectionModel() of JTable, you can get a reference to the ListeSelectionModel.
This is in fact an instance of DefaultListSelectionModel, which allows you to set a new listener object using addListSelectionListener(ListSelectionListener l).
All you have to do then is implement a custom ListSelectionListener which handles events as you want.
Unfortunately there isnt going to be a way of avoiding writing a Listener, but this is how you would go about it.

Date Format Error in Jtable

Can Somebody Guide me.I have a table in mysql database on windows 2000 which contains a short date field.Now my probem is that when I submit date values 10/01/2006 .It is entered in database as 29/12/1899 .I searched a number of websites also but nothing could help me.some examples will be helpful.
Thanks

What's the value of inserQuery? If you print out its value and run it directly on the database does it do what you expect?
It's often better to use a PreparedStatement to execute updates on the database:
PreparedStatement stmt = conn.prepareStatement("INSERT INTO my_table VALUES (?)");
stmt.setDate(1, myDate);
stmt.executeUpdate();That way you don't have to worry about what date format you need to convert your dates into to put them into the database.
Hope this helps.
