Using custom table model with the Net Beans JTable
I am using the net beans editor to create an application. For the JTable that net beans provides, I would like to use my own Table Model instead of the default one that is provided. How do I specify to the form editor that I want to use my own TableModel instead of the DeafaultTableModel?

JTable column headers not displaying using custom table model
Hi,
I'm attempting to use a custom table model (by extending AbstractTableModel) to display the contents of a data set in a JTable. The table is displaying the data itself correctly but there are no column headers appearing. I have overridden getColumnName of the table model to return the correct header and have tried playing with the ColumnModel for the table but have not been able to get the headers to display (at all).
Any ideas?

public class PublicationTableModel extends AbstractTableModel

JTable: Custom Table Model (pI)
This is a follow-up to thread http://forum.java.sun.com/thread.jspa?threadID=725162 and thread http://forum.java.sun.com/thread.jspa?threadID=725158.
As I'm hoping to have a table of 5 columns, where the 4th and 5th columns are for integer and float data types respectively, I am creating a custom table model under the assumption that I will not know beforehand the number of rows the table will contain.
Problems? Having not specified the cell contents of the table, since it will be pupulated by users unknown to me, I did not declare or initialize a variable similar to TableDemo's data variable of type Object (see the TableDemo tutorial http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/TableDemo.java). As such, I am unable to specify the return parameters for the getRowCount() and getValueAt(~, ~) methods.
To overcome this, I sought to replicate the example shown in TableDemo by doing the following:
Object[][] cell = {"", "", "", new Integer(0), new Float(0.00f)};
public int getRowCount()
returncell.length;
public Object getValueAt(int row, int column)
return cell[row][column];
//...I got the following errors:
pathname\CustomTableModel.java:line #: incompatible types
found: java.lang.String
required: java.lang.Object[]
and the errors continue...
So I tried
Object[] cell = {"", "", "", new Integer(0), new Float(0.00f)};
// ...However, I got this error:
C:\...\CustomTableModel.java:line #:array required, but java.lang.String found
return cell[row][column];
.......................... ^
I just want to set the return parameters for getRowCount() and getValueAt(~,~) in the custom table model I'm creating. How do I do this?
Cheers!
PS Thanks for reading this far...I decided to use the DefaultTableModel, after all. I was using it before, but at the time, i didn't know that certain things I wanted to accomplish, it could too.
Anyways, here's what I have been doing: http://forum.java.sun.com/thread.jspa?threadID=725861
Thanks nonetheless for your help. And by the way, my client is adamant that I use a LinkedList, rather than a Vector for this project. But nevertheless, thanks. -
Want to add rows from database in custom table model
Hello all,
I have written custom table model which has single blank row intially.
Once user clicks on button, i want to add more rows in custom table model and display them in JTable.
I have created JTable object as shown below.
Jtable patientTable = new JTable( new DiagnosticTableModel());
My custom tabel model is as shown below.
import javax.swing.table.AbstractTableModel;
public class DiagnosticTableModel extends AbstractTableModel
private String[] columnNames = {
"Date",
"Diagnosis",
"Severity",
"Medications"};
private String[][] data = {
public int getColumnCount()
return columnNames.length;
public int getRowCount()
return data.length;
public String getColumnName(int col)
return columnNames[col];
public Class getColumnClass(int col)
return getValueAt(0, col).getClass();
public Object getValueAt(int row, int col)
return data[row][col];
public boolean isCellEditable(int row, int col)
return true;
public void setValueAt(Object value, int row, int col)
data[row][col] = value.toString();
fireTableCellUpdated(row, col);
}Thanx a lot in advance.I have written custom table model which has single blank row intially.Why did you write a custom TableModel? The DefaultTableModel will work fine and it has methods that allow you to dynamically add rows to the table.

Dynamic Table Creation with the sortable collection model in the bean.
Hi all,
My requirement: I want to create the table dynamically with the set of rows. This set of rows will be holded in the Bean for the sortable variable.
(private SortableModel viewDeleteCollectionModel)
Issue: "_No Data to Display_" is coming in the Dynamic Table. Whereas when i checked with the collection model row count it is showing the correct no of rows.
Code for Dynamic Table in JSFF:
<af:table varStatus="rowStat" value="#{ViewHistoryDelete.viewDeleteCollectionModel}"
rows="#{ViewHistoryDelete.viewDeleteCollectionModel.rowCount}"
rowSelection="single" width="99%" var="row" id="t2" summary=" " >
<af:forEach items="#{ViewHistoryDelete.viewDeleteColumnNames}" var="name">
<af:column headerText="#{name}" sortable="true" sortProperty="#{name}" id="pt_c1">
<af:inputText value="#{row[name]}" label="#{row[name]}" readOnly="true" id="it2"/>
</af:column>
</af:forEach>
</af:table>
Bean Code:
Varaible DEclaration : private SortableModel viewDeleteCollectionModel;
Row assignig to collection model : viewDeleteCollectionModel = new SortableModel(new ArrayList<Map<String, Object>>());
((List<Map<String, Object>>) viewDeleteCollectionModel.getWrappedData()).addAll(viewDeletedData);
viewHistoryDelete.setViewDeleteCollectionModel(viewDeleteCollectionModel);
After this iam checked by putting sop for the table row count
iam getting actual no.of rows. But to the screen it is not showing the rows.
Any solution............

JButton in JTable with custom table model
Hi!
I want to include a JButton into a field of a JTable. I do not know why Java does not provide a standard renderer for JButton like it does for JCheckBox, JComboBox and JTextField. I found some previous postings on how to implement custom CellRenderer and CellEditor in order to be able to integrate a button into the table. In my case I am also using a custom table model and I was not able to create a clickable button with any of the resources that I have found. The most comprehensive resource that I have found is this one: http://www.java2s.com/Code/Java/Swing-Components/ButtonTableExample.htm.
It works fine (rendering and clicking) when I start it. However, as soon as I incorporate it into my code, the clicking does not work anymore (but the buttons are displayed). If I then use a DefaultTableModel instead of my custom one, rendering and clicking works again. Does anyone know how to deal with this issue? Or does anyone have a good pointer to a resource for including buttons into tables? Or does anyone have a pointer to a resource that explains how CellRenderer and CellEditor work and which methods have to be overwritten in order to trigger certain actions (like a button click)?
thanksYes, you were right, the TableModel was causing the trouble, everything else worked fine. Somehow I had this code (probably copy and pasted from a tutorial - damn copy and pasting) in my TableModel:
public boolean isCellEditable(int row, int col) {
//Note that the data/cell address is constant,
//no matter where the cell appears onscreen.
if (col < 3) {
return false;
} else {
return true;
}A pretty stupid thing when you want to edit the 3rd column... -
Custom table model, table sorter, and cell renderer to use hidden columns
Hello,
I'm having a hard time figuring out the best way to go about this. I currently have a JTable with an custom table model to make the cells immutable. Furthermore, I have a "hidden" column in the table model so that I can access the items selected from a database by their recid, and then another hidden column that keeps track of the appropriate color for a custom cell renderer.
Subject -- Sender -- Date hidden rec id color
Hello Pete Jan 15, 2003 2900 blue
Basically, when a row is selected, it grabs the record id from the hidden column. This essentially allows me to have a data[][] object independent of the one that is used to display the JTable. Instinctively, this does not seem right, but I don't know how else to do it. I know that the DefaultTableModel uses a Vector even when it's constructed with an array and I've read elsewhere that it's not a good idea to do what I'm trying to do.
The other complication is that I have a table sorter as well. So, when it sorts the objects in the table, I have it recreate the data array and then set the data array of the ImmutableTableModel when it has rearranged all of the items in the array.
On top of this, I have a custom cell renderer as well. This checks yet another hidden field and displays the row accordingly. So, not only does the table sort need to inform the table model of a change in the data structure, but also the cell renderer.
Is there a better way to keep the data in sync between all of these?To the OP, having hidden columns is just fine, I do that all the time.. Nothing says you have to display ALL the info you have..
Now, the column appears to be sorting properly
whenever a new row is added. However, when I attempt
to remove the selected row, it now removes a seemingly
random row and I am left with an unselectable blank
line in my JTable.I have a class that uses an int[] to index the data.. The table model displays rows in order of the index, not the actual order of the data (in my case a Vector of Object[]'s).. Saves a lotta work when sorting..
If you're using a similar indexing scheme: If you're deleting a row, you have to delete the data in the vector at the INDEX table.getSelectedRow(), not the actual data contained at
vector.elementAt(table.getSelectedRow()). This would account for a seemingly 'random' row getting deleted, instead of the row you intend.
Because the row is unselectable, it sounds like you have a null in your model where you should have a row of data.. When you do
vector.removeElementAt(int), the Vector class packs itself. An array does not. If you have an array, when you delete the row you must make sure you dont have that gap.. Make a new array of
(old array length-1), populate it, and give it back to your model.. Using Vectors makes this automatic.
Also, you must make sure your model knows the data changed:
model.fireTableDataChanged(); otherwise it has no idea anything happened..
IDK if that's how you're doing it, but it sounds remarkably similar to what I went thru when I put all this together.. -
Error while binding the model with the custom controller
Hi All,
I first started with a dummy project and in that binded the model with the custom controller.
For some reason, I deleted the project and created a new one. I have deleted the whole project from the workspace.
Now, when I am trying to bind the model again , I am getting an error when selecting the response parameters saying that DUPICATE ENTRIES.Ideally it should not happen when I am deleting it completely.
I am using a Webservice Model. Can any one help me out to resolve the same.
Looking forward for your response.

I did that and even I have Installed the IDE again.
Still I have that error.

I have a team site collection and I want to add a new App of type Issue Tracking list. so I did the following:-
From the site collection I created a new App of type issue tracking.
Then from the site collection I created a new Content type named “CustomIssue” which has its parent as “Issue” content type.
I went to the Issue tracking list and I changed the default content type from Issue , to the new “CustomeIssue” content type.
I open the site collection using SP designer and I created a new Create form for my Issue tracking list based on the "CustomIssue" content type and I select to have the Create form as the default form when creating an item.
Everything till this point worked well. But when I open the “customIssue” content type , and I re-order the columns and I hide some columns, this was not reflected inside the custom Create form …
although when using the default content type and the default create form you can control the order of the fields and to specify if certain fields hold be hidden inside the Create form.. so can anyone advice on this please?Hi,
According to your post, my understanding is that you lost the ability to order and hide site columns if i use custom content type with a custom Create Form.
I try to reproduce the issue, the result is the same as yours.
As a workaround, if I modify the custom content type form the site setting, and then change the NewForm as the default form, it will change the column orders.
However, if I use the new created form as the default form, it will remain the original orders.
I recommend that you modify the custom content type form the site setting, and then reset the NewForm as the default form.
The result is as below:

How to use a menu model with a dynamic region and a task flow parameter
I am using JDeveloper/ADF 11.1.2.1
I have a menu model that changes which task flow is displayed in a given dynamic region using a backing bean. That works fine. I would like to be able to pass parameters to that task flow based on which menu item is clicked. For example: i have a task flow which shows a page where input fields are used to filter a table. Depending on the value of the task flow parameter I want to change which input fields are displayed. So i will have multiple menu items which refer to the same task flow but have a different set of parameters. I have tried using request scope variables and setting them in the backing bean for the dynamic region which works until the query is submitted at which point the request scope has changed and the value is no longer available. I have tried a number of other 'creative' approaches but have not gotten anything to work. Anyone done this before? Or have an idea on how to solve it?Frank,
I did a fair bit of digging based on your suggestions and some things I found in your Oracle Fusion Developer's Guide book and I came up with something that works really well. It is fairly elegant but requires code. It would be nice if something like a setPropertyListener could be rolled into the menu model. That would make my solution completely declarative.
Here is my solution:
My task flow requires a the value #{pageFlowScope.type} to be set. My application has a dynamic region that is changed on the fly using a menu model. The region uses a backing bean (mainRegionManagerBean) which is in the viewScope to manage what taskflow is shown in the region. There are multiple menu items in the menu model that point to the same task flow but pass different values to the #{pageFlowScope.type} parameter. So i wired the menu items up to different methods in the mainRegionManagerBean which set the value for me. See the relevant code below.
I would be very interested in the feedback from someone with more experience than I on my solution. Maybe there is a more elegant way...
In the backing bean there is a primary method that was created by generating a dynamic region link which sets the task flow id and then other methods which call it and set the relevant parameters. (JSFUtils is a helper class i wrote to centralize some common tasks):
public String shipmentTraceMasterTaskflow()
taskFlowId = "/WEB-INF/taskflow/master/shipmentTraceMasterTaskflow.xml#shipmentTraceMasterTaskflow";
JSFUtils.setValue("pageFlowScope.type", "");
return null;
public String shipmentTraceProNumber()
shipmentTraceMasterTaskflow();
JSFUtils.setValue("pageFlowScope.type", "pronumber");
return null;
public String shipmentTraceBOLNumber()
shipmentTraceMasterTaskflow();
JSFUtils.setValue("pageFlowScope.type", "bolnumber");
return null;
In the menu model (notice that these reference the different methods from above):
<itemNode id="itemNode_ProNumberTrace" label="ProNumber Trace" action="#{viewScope.mainRegionManagerBean.shipmentTraceProNumber}" focusViewId=""/>
<itemNode id="itemNode_BOLNumberTrace" label="BOL Number Trace" action="#{viewScope.mainRegionManagerBean.shipmentTraceBOLNumber}" focusViewId=""/>
On the page:
<af:region value="#{bindings.dynamicRegion1.regionModel}" id="r1"/>
In the pagedef:
<taskFlow id="dynamicRegion1" taskFlowId="${viewScope.mainRegionManagerBean.dynamicTaskFlowId}" activation="deferred" xmlns="http://xmlns.oracle.com/adf/controller/binding" Refresh="ifNeeded">
<parameters>
<parameter id="type" value="#{pageFlowScope.type}"/>
</parameters>
</taskFlow>

JTable: Custom Table Model (pII)
As was explained in pI, I'm creating a custom table model to overcome a few pitfalls I came across using the DefaultTableModel class, such as aligning cells, and getting certain columns to return only numeric type data. However, I've come upon a few roadblocks myself.
How do I create each of the following methods:
insertRow(int ow, int column)
remove row(int row)
addRow(Object[] rowData)Assuming that I decide to allow the user to add a column to the table, how would I create the methodaddColumn(Object columnName, Object[] columnData)And also, as I'm creating a custom table model, would I need to replicate DefaultTableModel's methods that inform the listeners that a change has been made to the table?
Thanks!Thanks!
I just got this response. Anyways, I found another solution that was, interestingly, from one of your threads written in 2005.
This is what I did:
// Letting the JTable know what each column stores and should return by
// overloading the getColumnClass() method
public Class getColumnClass(int column)
if(recordsTable.getColumnName(column) == "Ranking")
return Integer.class;
/* Why do I keep ketting an IllegalArgumentException here? *
* It keeps saying it cannot format given object as a Number */
else if(recordsTable.getColumnName(column) == "Price (�) ")
return Float.class;
else
return getValueAt(0, column).getClass();
}However, another problem has arisen.
The if method for the int column (Ranking column) works okay, and is even right-aligned. The else if arguments for the Price (�) column however is returning an IllegalArgumentException. This I just cannot figure out.
Here's the code:package Practice;

Unable to get the SharePoint 2013 List names using Client object model for the input URL
Please can you help with this issue.
We are not able to get the SharePoint 2013 List names using Client object model for the input URL.
What we need is to use default credentials to authenticate user to get only those list which he has access to.
clientContext.Credentials = Net.CredentialCache.DefaultCredentials
But in this case we are getting error saying ‘The remote server returned an error: (401) Unauthorized.’
Instead of passing Default Credentials, if we pass the User credentials using:
clientContext.Credentials = New Net.NetworkCredential("Administrator", "password", "contoso")
It authenticates the user and works fine. Since we are developing a web part, it would not be possible to pass the user credentials. Also, the sample source code works perfectly fine on the SharePoint 2010 environment. We need to get the same functionality
working for SharePoint 2013.
We are also facing the same issue while authenticating PSI(Project Server Interface) Web services for Project Server 2013.
Can you please let us know how we can overcome the above issue? Please let us know if you need any further information from our end on the same.
Sample code is here: http://www.projectsolution.com/Data/Support/MS/SharePointTestApplication.zip
Regards, PJ Mistry (Email: [email protected] | Web: http://www.projectsolution.co.uk | Blog: EPMGuy.com)Hi Mistry,
I sure that CSOM will authenticate without passing the
"clientContext.Credentials = Net.CredentialCache.DefaultCredentials" by default. It will take the current login user credentials by default. For more details about the CSOM operations refer the below link.

Using custom tables in jdeveloper
Hi,
I've created a custom table using toad. I created the table in applsys and created a synonym to apps. I've also grant all the priveledges to apps as well. However, when I create a query OA to query a standard table eg. PER_ALL_PEOPLE_F, I have no problems however, using the same OA to query my custom table, I get the JBO-25017 Cannot create row for entity error.
Is someone able to help??Why it was required to chnage your EO to abstract class?. May be your custom table doesn;t have the standard WHO columns (created_by, Creation_date etc..), and the EO doesn't compile with out a attribute setter/getter methods for these columns.
this may be the reason why you changed the class to abstract. But, EO class should not be abstract. Work around is to have empty functions for these standard columns.
