Hello Valter Oliveira,
Thanks for your answer. But I need some more detail about blank line text. i.e thrid point.
Could you please tell me how to insert blank line text.
1 - in your table, create a line type with only one column, with the same width of the table
2 - in table painter, create a line under the line type
3 - insert a blank line text in the footer section with the line type you have created.

How to enter the values in JTable in runtime

how to enter the values in JTable in runtime

Basically you need a vector of vectors or an array of arrays. Example (off the top of my head):
With Arrays
String[] cols = { "colone", "coltwo", "colthree", "colfour", "colfive" };
String[] numbers = { "one", "two", "three", "four", "five" };
String[] letters = { "A", "B", "C", "D", "E" };
String[][] data = { numbers, letters };
//make sure that the table has a scroll pane wrapped around it otherwise the header is not displayed
JScrollPane scroll = new JScrollPane(new JTable(data, cols));
With Vectors
Vector cols = new Vector();
cols.addElement("colone");
cols.addElement("coltwo");
cols.addElement("colthree");
cols.addElement("colfour");
cols.addElement("colfive");
Vector numbers = new Vector();
numbers.addElement("one");
numbers.addElement("two");
numbers.addElement("three");
numbers.addElement("four");
numbers.addElement("five");
Vector letters = new Vector();
numbers.addElement("A");
numbers.addElement("B");
numbers.addElement("C");
numbers.addElement("E");
numbers.addElement("F");
Vector data = new Vector();
data.addElement(numbers);
data.addElement(letters);
//make sure that the table has a scroll pane wrapped around it otherwise the header is not displayed
JScrollPane scroll = new JScrollPane(new JTable(data, cols));The array or vector can be easily populated at runtime.

Query by example - how can I display VCRow in JTable?

I would like to provide the user with a searchable table.
Actually I would like to use two tables: one, displaying one row where the user can specify the search criteria. And the second table should display the data found.
I could store the entered criteria locally in a hashmap in TableModel, for example, then create a WHERE clause. This solution is quite messy, since the user can add, remove and rearrange the columns of both tables.
Or I could use -I hope- the query-by-example feature, like this:
am = app.getApplicationModule();
ViewObject vo = am.createViewObject( "MyVO", "mypackage1.PatView" );
ViewCriteria vc = vo.createViewCriteria();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
Now I can set attributes and use vo.applyViewCriteria() to find my data.
But how can I bring the first JTable to display this single ViewCriteriaRow, so that the user can do the editing?
The JUNavigationBar does it, if I am not mistaken. It switches the PanelBinding to find mode, and then a JTable displays a ViewCriteriaRow (?) instead of the ViewObject's data. But I don't want to use the bar. How do I create this behaviour manually?
The javadoc of JUPanelBinding says:
"Sets this panel and all its associated iterators into find mode."
So I guess that setting iterators into find mode is what I need. But I cannot figure out how to do that. Who can?

You cannot set the iterators in a panelBinding to separate find/data modes individually.
However you can create two JUPanelBinding objects one for the findMode form and one that displays Data.
here's what I did to modify a generated SingleForm, to display two panels of the same type one in find mode and other in data mode.
I changed the jbInit method of the "LayoutPanel" class to be like:
//declare this as a member of the class.
JButton findBtn;
public void jbInit() throws Exception
// Panel layout
masterViewPanel = new PanelDeptView(panelBinding);
//create another instance of PanelBinding for a second (findform) DeptView panel.
JUPanelBinding binding = new JUPanelBinding("Project3.Mypackage1Module", this);
binding.setApplication(panelBinding.getApplication());
masterViewPanel1 = new PanelDeptView(binding); //create second instance
findBtn = masterViewPanel1.navBar.getButton(JUNavigationBar.BUTTON_FIND);
findBtn.doClick(); //set the second instance in find mode.
//add a listener on the second instance's execute button so that it resets the form into find mode
//this forces the second instance to be in find mode when execute button is pressed.
masterViewPanel1.navBar.getButton(JUNavigationBar.BUTTON_EXECUTE).addActionListener(new ActionListener()
public void actionPerformed(ActionEvent ev)
SwingUtilities.invokeLater(new Runnable() {
public void run()
findBtn.doClick();
this.setLayout(panelLayout);
add(masterViewPanel, BorderLayout.WEST);
//add the second instance.
add(masterViewPanel1, BorderLayout.EAST);
I also had to call findBtn.doClick() again in the "constructor" that takes (JUApplication, boolean) after the panelBinding is executed,
to force the initial startup of this panel in findmode

How to populate data in a JTable?????????

hi there
can anyone tell me how to populate data in a JTable? when a table is displayed, the table should have data retrieved from a file. thank you.

Hi,
it is correct, that the best way to learn about JTable is to read the online tutorial about JTable. To give you a quick guideline, where to start your implementation, I will add this:
A JTables data is hold in a TableModel. TableModel is an interface, so if a class implements this interface correctly, you can simply populate the data hold by this TableModel by constructing a JTable this way
JTable jt = new JTable(MyTableModel);
where MyTableModel is your class, which implements the TableModel interface.
When JTable has to render a cell, it will call the getValueAt(...) method of the TableModel for example.Your implementation of this method must deliver the requested data - if you prefetch a bunch of data from a file and store it internally in this TableModel or fetch it from the file just in time, is up to you.

How to append records in a file, through file adapter.

Hi All,
How to append records in a file, through file adapter.
I have to read data from database and need to append all records in a file.
Thanks in Advance.

Hi,
I think you have a while loop to hit the DB in your Process (As you said you have to fetch data from DB 10 times if 1000 rec are there)
First sopy your DB O/P to one var
and from second time append to previous data.(Otherwise you can directly use append from starting instead of copy and append)
When loop completes you can transform to File adapter Var.
Otherwise you can configure yourFileadapter such that it will aapend current records to previous records.
You can use 'Append= true' in your file adapter wsdl.
It will append previous records to current records in the same file.

 StringBuffer buf = new StringBuffer();
 try {
 buf.append("bb");
 buf.append("ccc");
 // First append to document
 g.pane.setText(buf.toString());
//Second append
 buf.append("ddddd");
 g.pane.setText(buf.toString());
 } catch (Exception e) {
 System.out.println(e.getMessage());
I know that this method is not smart and doesn't look good, but it works.
If you know how to append html using HTMLEditorKit and HTMLDocument please write some example.

CREATE OR REPLACE TRIGGER checkout_trg

DECLARE

> It's for an assignment...I think thye're just trying to show us what's possible.
Just as it is possible to show a learner driver to jump a red light, drive on the wrong side of the road, or do doughnuts in an intersection...
But none of this will make that learner driver a good driver. Never mind able to correctly handle high performance cars on the professional circuit.
Sorry mate - what they are showing/teaching you is pure bs. A trigger is not the "same thing" as a callback event in client programming.
And feel free to give them this URL and tell them that I think they are full of it. Let's see how they defend their non-real world, totally irrelevant and wrong assignments in this very forum.
