ADF Swing Form Layout

Hi,
I am new to ADF swing and developing my very first applications and I am running into following challenges.
1. After creating business components(model) and view components, I created an empty form
2. From Data Control , I selected collection of attributes and dragged to the ADF Form area.
3. Then, clicked on Edit Form ,and made necessary changes and then confirmed the changes.
Now, I see that layout is completely locked or frozen. I can not drag or move any labels or any fields. I also can not resize any text field.
After reviewing further documentation, I set column property in helper.java file but still I can not resize, or move any of the field.
Any idea why it is not working? Also tried passing following in the code but still no luck
setMaximumSize(new Dimension(80, 70));
setPreferredSize(new Dimension(50, 50));
Please advise.
Thanks,
Darsh

Thanks Frank.
I have gone through the link provided. This approach sounds like more time consuming from development standpoint. I will explore more. But now I am contemplating to move to Netbeans. Not being able to use Java Swing in same manner as ADF swing and the fact that ADF Swing has been deprecated makes me think that way.
This does bring up a point from Oracle's technology direction though. It appears that technology to deliver native, standalone, traditional desktop applications are just not going to be supported anymore from Oracle and with cloud computing gaining momentum as time passes, it will become increasingly challenging to find a desktop development tool in Oracle's offering.
Would you agree?

Adf swing form login problem (Frank, look at this please)

Hi All. I'm using JDeveloper 10.1.3
Can anybody please give me a clue on how to create a simple stand alone adf swing form with a login dialog and the oracle jaas authentication?
For me this kind af appllications works well only in design time :(. When i try to launch my generated .jar application the login dialog does appear but the authentication
doesn't work "incorrect username or password".
So i think i followed all the instructions from jDeveloper online help concerned with generating a login dialog... but my application still doesn't work properly after deployment.
Please somebody look at what i've done and tell what is wrong.
1. I created an adf swing form with a login dialog.
2. I set the jbo.security.enforce property for my application module to Must.
3. I added to my application a dialog for adding, removing and modifying application users via oracle.security.jazn api.
4 I tested my appllication in Jdeveloper. It works great! I even added a number of application specific default users via my application.
5. I assured myself that the oc4j security library has been added into the adf/swing project as well as into the deployment profile.
6. I deployed my apllication to a .jar file.
7. I created "config" folder inside the directory where the.jar file has been dropped. I copied there the following files: jazn.xml and system-jazn-data.xml (the last one file includes all my previously created principals) from /jdev_home/j2ee/home/config.
8. Now when i start the application the login dialog appears as i've mentioned but authentication doesn't work.
I found only one similar topic over the whole forum:
http://kr.forums.oracle.com/forums/thread.jspa?threadID=665430
but what i've done seems to meet all Frank's advices.....
Oracle staff please dont ignore my post.
Thanks in advance.

Hi, rob nice to learn that i'm not the only one stumbled over this issue.
Hope that this question will be finally answered...
...just a few additional comments.
1. It appears that the position of the jazn.xml and jazn-data.xml files pointed in the documentation (config subfolder of the root .jar's folder) is right for if i rename or delete the jazn.xml it runs into the error: jazn configuration file not found, but nevertheless it works strange, it looks like it doesn't use the mentioned files at all....given the fact the i've already spent a number of days experimenting and looking for a solution i learned that after a first startup the files mentioned above (jazn.xml and jazn-data.xml) are modified in some way that prevents using them on another oc4j server instance (if i have i.e. another jdeveloper instance, i cant run and go through authentication in my application by simply coping the old jazn.xml and system-jazn-data.xml files into the /jdev_home/j2ee/home/config
folder...instead i need to copy a pure "initial" jazn.xml file from the initial jdeveloper archive) ... something like the thing mentioned here:
http://radio.weblogs.com/0118231/stories/2007/05/08/jdeveloperadf11gTechnicalPreviewTipsAndTricks.html
also i noticed that if there is no system-jazn-data.xml file in the config folder it is created automatically after a first startup...so when i tried to delete the system-jazn-data.xml file from my deployed application's folder it would't create a new one though it saw the jazn.xml file (since no "jazn configuration file not found" error had ever appeared)...i also tried to place "pure" copies of jazn configuration files in my config subfolder but of course it would give no effect.
2. i also changed the login.module.provider as well as the auth.policy.provider properties in the java.security file as documentation sais - no effect.
So it would be great if Frank gave us a direct link to the white paper he was working on (and i hope had finished :) few years ago....or even better gave me the simpliest example of a finished adf swing application with authentication implemented.

ps. we know it's really really time consuming answering all questions but considering the lack of documentation on adf swing technology i hope we can rely on your help here.
thanks.

Adf swing form problem

i created two adf swing new empty forms.. and i'm triying to open form2 (form2
have some components) with a click button from form1.
i'm using this code on the event click button
Form2 a = new Form2();
a.setVisible(true); //or a.Show();
after the click, the new form (a) appears without components and in a minimum
size bar.

It sounds like you have them displaying properly in a JFrame if you can get to the button from Form A and click the button. Your subject says "ADF Swing", so I assume you have bound your components that are on Form B. If that is the case, then you need to call setBindingContext() on Form B to get the ADF binding to execute. Here is a small sample assuming that you are using ADF Swing bindings and have also generated a Form with a binding context.
// In the actionPerformed method of your button
BindingContext ctx = panelBinding.getBindingContext();
Form2 a = new Form2();
a.setBindingContext(ctx);
a.setVisible(true);
...Hope this helps.

ADF Swing Empty form probmlem

Hello,
I'm trying to follow the "Build a Java Swing Application with Oracle ADF"Cue Cards. I'm stocked at the step 5 (create a Master Form in ADF Swing Form).
When I try to add a collection OrdersView1 to empty form I've got error messages:
D:\JDeveloper\tutorial\OrdersApplicationADF\View\src\view\PanelOrdersView1Helper.java
Error(99,30): identifier $objects not found
Error(105,30): identifier $objects not found
Error(111,30): identifier $objects not found
Error(117,30): identifier $objects not found
In the xml there is following code:
if ("Hide".equalsIgnoreCase(panelBinding.getDisplayHint("OrdersView1",
"OrderDate",
null))) {
dataPanel.remove(mOrderDate);
dataPanel.remove($objects.LabelVariableName);
if ("Hide".equalsIgnoreCase(panelBinding.getDisplayHint("OrdersView1",
"OrderId",
null))) {
dataPanel.remove(mOrderId);
dataPanel.remove($objects.LabelVariableName);
if ("Hide".equalsIgnoreCase(panelBinding.getDisplayHint("OrdersView1",
"OrderStatusCode",
null))) {
dataPanel.remove(mOrderStatusCode);
dataPanel.remove($objects.LabelVariableName);
if ("Hide".equalsIgnoreCase(panelBinding.getDisplayHint("OrdersView1",
"OrderTotal",
null))) {
dataPanel.remove(mOrderTotal);
dataPanel.remove($objects.LabelVariableName);
Can you help me? What I did wrong?

Hi,
Timo's approach works if you use e.g. ADF BC and then drag the "Create" operation as a method activity to the task flow diagram before you navigate to the view. As Timo mentions, if you want to abandon the row you can't just press cancel but i) navigate to another method activity you create from the "Delete" operation, or ii) access the current row in the iterator to remove it there before navigating off.
Another approach is to expose a method on the ADF BC client interface that creates a new row in ADF BC. You can then drag and drop the method as a parameter form, which initially would be empty

How to bind value from one form to another form in ADF Swings

I am very new to ADF Swings need an Help ! . I have generated two forms one in FILTER FORM and another one is DETAILS FORM. Two parameter are defined in Filter Form 1. Name and 2 .Id and values are entered in textbox and combo box .Based on selected record or entered value in FILTER FORM i have to display that matching or filtered records in DETAIL FORM .I working this in ADF Swings . At present i am retrieving and displaying the records from a single table .
Regards

Hi frank,
Thanks for the reply . I was trying in other way by the following code . But here i am getting class cast exception in line number five. Can you provide a few step to sort out the issue.
private EatonSalesOrderDemo eatonSalesOrderDemo=new EatonSalesOrderDemo(); [Object Created For Details Screen]
eatonSalesOrderDemo.setBindingContainer(createDetailBinding()); [ With the reference setting Binding Container]
DCIteratorBinding iterBinding = getPanelBinding().findIteratorBinding("...."); [get master current row, get detail accessor iterator, then bind detail form iterator binding to detail accessor iterator ]
Row row = iterBinding.getCurrentRow();
RowSetIterator detailAccessor = (RowSetIterator)row.getAttribute("....");
eatonSalesOrderDemo.getPanelBinding().findIteratorBinding("....").bindRowSetIterator(detailAccessor, false);
eatonSalesOrderDemo.setVisible(true);
int count = 0;
private DCBindingContainer createDetailBinding()
String detailBCName = "EatonSalesOrderDemoPageDef"+count;
if (panelBinding.getBindingContext().get(detailBCName) == null)
DCBindingContainerDef bcdef = DCBindingContainerDef.findDefObject("oracle.eaton.view.pageDefs.EatonSalesOrderDemoPageDef");
DCBindingContainer bc = bcdef.createBindingContainer(panelBinding.getBindingContext());
bc.setName(detailBCName);
panelBinding.getBindingContext().put(detailBCName, bc);
++count; //make sure the next name is unused thus far.
return bc;
return null;

Help required building ADF-Swing/ADF-Faces using ADF Business Components

My question is in regards to how you can go about building a light swing application to an ADF model?
In particular if I were to say that we were developing a 3-tier project whereby we had a database tier, a series of EJB-ADF façade session beans to the database (middle-tier), and a swing client communicating with the session beans (view-controller tier), how would you go about developing these screens?
In particular can we develop these screens using ADF-Faces and also ADF-Swing?
The EJB session façade beans of course are ADF app modules with customised methods. The methods would return back customised DTO objects. These DTO objects are wrappers to row objects ADF would create. This would be mainly due to making these facade beans web service enabled (Oracle state that these methods cannot return oracle.jbo objects if they are to be web service enabled).
This would be typically deployed to an app server, like Oracle App Server 10G.
Could you please have a look at this, as I am doing a lot of research into this.
eg. Taking example from oracle magazine sept/oct 2006
with slight enhancements
package oramag.frameworks.example.common;
import oracle.jbo.ApplicationModule;
import oramag.frameworks.customdto.EmployeeDTO;
public interface HRService extends ApplicationModule {
void deleteCurrentEmpAndCommit();
EmployeeDTO findEmployee(int employeeId); // new method
import oramag.frameworks.customdto.EmployeeDTO;
public class HRServiceImpl extends ApplicationModuleImpl {
public void deleteCurrentEmpAndCommit() {
Row empRow = getEmpView().getCurrentRow();
if (empRow != null) {
empRow.remove();
getDBTransaction().commit();
public EmployeeDTO findEmployee(int employeeId)() {
EmployeeDTO employeeDTO = null;
EmployeesImpl employees = getEmployees();
employees.setNamedWhereClauseParam("EmployeeId", employeeId);
employees.executeQuery();
if(employees.hasNext()) {
EmployeesRowImpl employee = (EmployeesRowImpl)employees.next();
employeeDTO = new EmployeeDTO(employee);
return employeeDTO;
public EmployeesImpl getEmployees() {
return (EmployeesImpl)findViewObject("Employees");
Now given the above code snippet, how could you turn this into an ADF-Swing/ADF Faces application so that if a user using the swing application enters an employee id, then the application will execute the query on the app server, the app server in turn returns the results to the client, and the client finally display the results. Typical MVC example.
Cheers
Rodney

The tutorial is for ADF BC used with JavaServer Faces.
While the tutorial doesn't cover it, we also support drag and drop development for Swing and visual WYSIWYG layout for Swing panels and windows, too. For a very simple example, watch screencast #4 on my blog here:
http://radio.weblogs.com/0118231/stories/2005/06/24/jdeveloperAdfScreencasts.html
One thing I have noticed is that when using ADF business components, when the app module returns a custom DTO object like the above example, it returns the data in a element structure according to the data control palette.
You don't generally ever need to create your own custom DTO's when working with ADF for use by client UI's. The only situation where can be necessary -- until we simplify this in the JDeveloper/ADF 11g release -- is when you desire to expose custom methods that can return sets/arrays of typed row structures through a web service. However, web services are not involved/required in building 3-tier Swing applications.
When dropping onto a page it does so like a string and doesnt give option to display the data in a read only form etc. Is there anything we need to do, to get the functionality.
It's more of what you don't need to do :-)
Just leverage the active data model that the ADF application module provides. You can read more about it in section 4.5 "Understanding the Active Data Model" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html). Your UI's bind to view object instances in the data model, and your UI's are automatically kept up to date without needing to write methods that return data. I short article I wrote that preceeded my writing the ADF Developer Guide content on this topis is here:
http://radio.weblogs.com/0118231/stories/2006/01/26/theAdfBusinessComponentsActiveDataModel.html
I know that when dropping a view object you get this functionality. Also was wondering if we were to pass an object of thios type back to the model it might not give us the rich functionality like input forms, like what Oracle provides if we were to drop a enitity view object.
Just use the active data model and everything becomes totally easy, with no changes required to switch between local or three-tier deployment configurations.
Trying to do everything with hand-coded DTO beans is really going the hard way.
Could you help us regarding this?

ADF Swing LOV problem

Hi,
I created an application using ADF Swing with JDeveloper version 10.1.3.2.0.4066.
I made a form contains JTable and Edit Form which using some LOVs to insert or update data. Something weird happen when user insert data using LOV.
Scenario:
1. firstly, JTable contains some data, let say 5 records.
2. User want to input some new data (the sixth record), then user push (+) button in JUNavigationBar, then one new record is added into JTable
3. User want to edit the new record, then user push Edit button which will display Edit Form
4. User push button which will display LOV to insert the correct record, after selecting a record from LOV then user push OK button from LOV form, then LOV form will be closed.
5. User performing commit to permanently save data to database.
now, the weird part:
6. User want to input the second record, then user push (+) button in JUNavigationBar, then one new record (the seventh record) is added into JTable
7. User want to edit the new record, then user push Edit button which will display Edit Form
8. User push button which will display LOV to insert the correct record, after selecting a record from LOV then user push OK button from LOV form, hoping that LOV form will close but NOT. User need to push OK button twice to make the LOV Form closed.
so that is the weird thing, if user input the third record (the eighth record), then user need to push OK button three times to make the LOV Form being closed, if user input 100 record then user need to push OK button 100 times to close LOV Form. Weird?
but if user close the main form first, then display the form again and input the new record using LOV (the seventh record), the weird thing is not gonna happen.
how I can solve this weird thing?
thanks

below is step by step creation of ADF Form and how the error happened and handled (using Oracle JDeveloper 10.1.3.3.0.4157) :
1. create database connection using JDeveloper wizard.
a. supply connection name: dbscott
b. supply username: scott, password: tiger, deploy password is checked.
c. Driver: thin, hostname, JDBC Port, and SID as installed
d. test connection: sucess
2. from JDeveloper, open Application Navigator and then create new application:
a. application name: ScottApp
b. application path: default
c. application package prefix: test.scott
d. application template: [Swing, ADF BC]
e. OK button pushed
3. now, configuring Oracle Business Component:
a. from Model project, right click and select New
b. select ADF business component from business tier and select Business Components from tables on the right pane
c. click OK
d. select dbscott on the connection option. SQL Flavor and Type MAp: default
e. click OK
f. with only object type table is selected, shuttle all table object into selected pane and specify package to test.scott.model.entities
g. click next
h. shuttle all object into selected pane and specify package to test.scott.model.queries
i. click next twice
j. specify application module: ScottModule
k. click next and then finish
4. now, creating ADF Form object
a. on the View Project, right click and select New
b. select ADF Swing on the client tier and empty form on the right pane
c. click OK
d. supply form name: EmpForm, generate menu bar and generate login dialog option is unselected
e. click next and then finish
f. then JDeveloper will display its excellent Swing Editor, select JUNavigationBar on the EmpForm and then delete
g. click form EmpForm and on data Panel specify layout to FormLayout
h. on the FormLayout popo up menu, specify rows to 8 and columns to 3, insert gap is selected, click OK of course.
i. on the data control palette, drag and drop EmpView1 to the first rows and column, then on the Add Child menu select Navigation Bar
j. select NavigationBar, on the blue point, drag to the third column. right click NavigationBar, select Column Properties menu and click grow. then OK
k. on the component palette, select Swing Container, drag and drop JScrollPane to the second row and first column
l. with JScrollPane selected, on the blue point drag JScrollPane so its covers second to seventh row and first to third column
m. right click on JScrollPane, select Row Properties menu and select Grow. click OK then
n. on the Data Controls palette, drag and drop EmpView1 to JScrollPane, on the Add Child menu select table.
5. now, creating ADF Edit Form object:
a. rigth click on the View Object, select New
b. select ADF Swing on the client tier and select Empty Panel on the right pane.
c. Panel name: EditEmpForm, other option default
d. click next and finish
e. then JDeveloper will display EditEmpForm editor
f. on the Data Controls palette, drag and drop EmpView1 to EditEmpForm then select Add Edit Form
g. then Select Contrl window will be displayed. Click new to add LOV for Deptno
h. new attribute will be added on the bottom, change attribute to Deptno and its control to Button LOV. create label option for this attribute is unselected.
i. click OK
j. adjust width and height the new panel created by JDeveloper properly
k. in the Application Navigator, double click PanelEmpView1Helper, supply text for Deptno LOV JButton.
6. configuring Deptno LOV JButton:
a. with LOV JButton is selected, select model in its property inspector, then model window will be displayed
b. LOV Update Attribute Tab is active, in Lov (source) Data Collection Pane, select DeptView1 and click New buttion below to create new iterator, click OK to create new iterator for DeptView1.
c. click add button to add LOV attributes
d. select deptno in the LOV Attributes and select Deptno in the target attributes.
c. select LOV Display Attributes, shuttle all attributes to the right pane.
d. click OK to finish configuring LOV
7. adding EditEmpForm to EmpForm:
a. with Empform is active in the editor, from Application Navigator drag and drop EditEmpForm.java to the last row on the first column of EmpForm.
b. Select Option window will be displayed, select Display Panel in JDialog and Invoke JDialog from Button option is selected
c. then a JButton will be added to last row on the first colum of EmpForm. Adjust this button to be displayed properly
Then the creation of ADF Form is complete. We're able to create this powerful form with NO CUSTOM PROGRAMMING AT ALL, it's all because of Oracle ADF. But wait... we will run this scenario to perform how the error happen.
Assumption, a user want to perform edit and insert data on EmpForm. He will perform following task:
a. Run EmpForm, then the form will be displayed at runtime.
b. The user want to edit data first, so he select a row then click Edit button, then EditEmpForm will be displayed.
c. user edit one or more data, displaying LOV to edit Deptno. at this time, he just need to push OK button at LOV Form once. After completing edit, user close EditEmpForm by clicking OK button, EditEmpForm will be closed.
d. now, user want to insert new record, simply at EmpForm user click (+) button at navigation bar to create new record, user click Edit button to display EditEmpForm, the user filling new information and of course diplaying LOV to select Deptno, now user need to click OK button in LOV form TWICE to be able to close the LOV Form. The user then click OK button to close EditEmpForm and back to EmpForm.
e. The user think that just intermittent error, now he want to update data again. So, he do perfectly the same step before but now he need to click OK button from LOV Form THREE TIMES to close LOV Form. The user then click OK button to close EditEmpForm and back to EmpForm.
f. after thinking hardly why this happened to him, the user then performing commit transaction then close EmpForm and open again.
g. now user perform update data again but this time he just need to click OK button from LOV form once.
The above error will not happened if the user open EditEmpForm just once ! if he close and open again EditEmpForm then he need to click and click OK button from LOV Form as many as he open EditEmpForm.
I don't know why this happen, if something not right from how I create the application which causing this error, please let me know.

Problem with "find" mode in adf/swing application

Hi all,
I'm working on ADF Swing application which uses MS SQL Server 2005 (JDeveloper 10g 10.1.3)
I think that my issue might be well-known…sorry if it has been already discussed somewhere else…
I have a problem with the “find” mode for a detail panel in a master-detail form…(To make it clear the “find” mode is switched on when clicking on the special button on a navigation panel).
So this mode works well in a master panel, but it demonstrates strange behavior on a detail panel, i.e. it takes me two attempts to find the necessary child object and it doesn’t switch back in a simple way from this mode to the normal mode….say if we are in the department 10 (Dept is a master form) we can’t simply find KING employee (Emp is a detail form)…is there any workaround for this?
Thanks in advance. Alex.

Hi Frank, please look this issue

How to build a BIG TREE with Tree-Form layout

Hi,
I do have a self-referenced table with our org structure - 15 000 positions.
I do want to create a tree with this structure.
Requirements :
a, to have a tree-form layout
b, to have search capabilities
I have tried to use several combinations (maybe all)
- from using only one View object and create recursive tree - doesn't even run
- to use two View objects, first as top level nodes, the other as the rest - it runs
but I can search only top level, and what is worse, by clicking on the node for showing additional information (tree-form layout) I'm waiting for ages for seeing the info
(it seems that all records are loaded one by one into AS)
Could you provide some ideas how to deal with this ?
Thanks.

I am sorry, this is beyond the scope of this forum.
As with any functionality not directly provided by JHeadstart, you can build it yourself using the ADF design time tools in JDeveloper. Please use the JDeveloper forum for help on this first step.
Then, to keep your pages generatable you can move these customizations to custom templates. We are happy to help you with this last step, should you have problems there.

ADF Swing panel Issue

Hi,
I have requirement where i need to use 2 Panels in a form. I have used JPanel in ADF Swing like what we used Panel Box in ADF. When I am running the application, The data in the first panel is coming up where the second panel data is not showing. I am using J dev 11.1.1.3.
Can you please help me in this regard.
Regards,
Kalyan.

As I understand you have 2 JPanels implemented as 2 separate Java classes and you invoke <tt>panel.setBindingContext(bctx)</tt> on each of them. This method binds the corresponding panel to its PageDef. If you use only one common PageDef instance then one of your panels will remain unbound. In order to resolve this problem you have to either combine your panels in a single JPanel or to provide a separate PageDef instance for each of them. You should either define a separate PageDef or you can try to duplicate PageDef's declaration in DataBindings.cpx (without duplicating the PageDef's XML file). If you choose the second one then open the <tt>DataBindings.cpx</tt> file and copy the corresponding line, for example:
<pageDefinitionUsages>
<page id="MyPanelPageDef" path="view.myproject.pageDefs.MyPanelPageDef"/>
<page id="MySecondPanelPageDef" path="view.myproject.pageDefs.MyPanelPageDef"/>
</pageDefinitionUsages>In this way you will declare a new PageDef instance without duplicating the PageDef's file. Then go to the beginning of the 2nd panel's Java class and set the new PageDef ID into it, for example replace the line:
private String pageDef = "MyPanelPageDef"; with private String pageDef = "MySecondPanelPageDef"; (Of course, these names are just sample ones and you should set the corrent ones).

ADF Swing problem

Hi,
We have some ADF Swing projects converted into libraries.
and these Library files are going to be used in another project.(it's done already)
problem :
this is an event that is supposed to call a form from a library :
private void jButton1_actionPerformed(ActionEvent e) {
LocationListForm lf = new LocationListForm();
Lf.main(null);
"LocationListForm " has a JPanel named "locationListPanel1"
when the "Lf.main(null)" is called we have a problem with this line (in main method) :
locationListPanel1.bindNestedContainer(panelBinding.findNestedPanelBinding("view_LocationListPanelPageDef1"));
"panelBinding" is returned null and on the Bold line we get an exception.
public void bindNestedContainer(JUPanelBinding ctr) {
//Exception on this line
*if (panelBinding.getPanel() == null) {*
ctr.setPanel(this);
panelBinding.release(DCDataControl.REL_VIEW_REFS);
panelBinding = ctr;
registerProjectGlobalVariables(panelBinding.getBindingContext());
try {
jbInit();
} catch (Exception ex) {
ex.printStackTrace();
ctr.reportException(ex);
Please Advise,
Thank you
