[ADF Swing] Manage exceptions

Hi all!
I want to manage exceptions handling in a Swing ADF application. In my Application Module, I have a method that adds data in the DB (by creating a new row in the corresponding VO, etc). This method is called by an object whish is in the application view project. When a constraint violation occures, I'd like that Application Module method catch the JboException and throw it to the calling Java object. The traditionnal way to throw exception doens't work:
public void addMethod(params) throws CustomException
try
catch(JboException e)
throw new CustomException(e.getMessage());
So I create my own mechanism with event and listener, but I suppose that a common way should exists.
Could somebody help me?
Regards

Mark,
exceptions are catched and handled in the page lifecycle. See:
http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content/navId.4/navSetId._/vtAnchor.CIHHBEEJ/vtTopicFile.adfdevguide%7Cweb_val%7Ehtm/
An implementation of this is available in the SRDemo example you get through

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

Adf/swing binding problem

Hi all,
Friends i need your help.
I was a bit confused as i started developing an adf/swing application. I know that this project is not supported any more but i honestly believe that there are a lot of people still using it.
I've already faced with a number of problems and successfully solved them but the one is really strange.
Before describing it let me ask one preliminary question. It’s very important for me, but if it is too much …. skip the first question since the second one is the most important.
1. I’m creating a multiframe application where I have one main window (with a desktop pane) which does not include any bindings and is used for invoking internal frames only which in their turn have been created by dragging and dropping data controls.
Since JDeveloper only allows generating skeletons for stand-alone frames and there is lack of information concerned with adf/swing developing I’m trying to fit the automatically generated code for my purpose by myself.
I obsessively ask some GURU to check my strategy and say whether I’m doing it right.
First I create the BindingContext object in the main frame:
BindContext ctx = newBindingContext();
public MainFrame() {…………
try {
JUMetaObjectManager.setErrorHandler(new JUErrorHandlerDlg());
JUMetaObjectManager mgr = JUMetaObjectManager.getJUMom();
mgr.setJClientDefFactory(null);
ctx.put(DataControlFactory.APP_PARAM_ENV_INFO, new JUEnvInfoProvider());
ctx.setLocaleContext(new DefLocaleContext(null));
HashMap map = new HashMap(4);
map.put(DataControlFactory.APP_PARAMS_BINDING_CONTEXT, ctx);
mgr.loadCpx("minit.org.view.DataBindings.cpx" , map);
DCDataControl app = (DCDataControl)ctx.get("AppModule1DataControl");
app.setClientApp(DCDataControl.JCLIENT);
} catch (Exception ex) {
JUMetaObjectManager.reportException(null, ex, true);
System.exit(1);
Then I pass the BindingContext object into the internal frames constructors, i.e.
private void jMenuUnitVoc_actionPerformed(ActionEvent e) {
this.getJMenuUnitVoc().setEnabled(false);
FormCreateUnitView1 unitVoc = new FormCreateUnitView1 (ctx);
unitVoc.setVisible (true);
this.deskTopPane.add (unitVoc);
Then I setup the panel binding for a particular JinternalFrame instance through the automatically generated setBindingContext() method:
public FormCreateUnitView1(BindingContext ctx) {
try {
this.setBindingContext(ctx);
} catch (Exception ex) {
JUMetaObjectManager.reportException(null, ex, true);
System.exit(1);
This predefined setBindingContext () method looks like this:
public void setBindingContext(BindingContext bindCtx) {
if (panelBinding.getPanel() == null) {
panelBinding = panelBinding.setup(bindCtx, this);
registerProjectGlobalVariables(bindCtx);
panelBinding.refreshControl();
try {
jbInit();
panelBinding.refreshControl();
} catch (Exception ex) {
panelBinding.reportException(ex);
panelBinding instance variable is declared by default as
private JUPanelBinding panelBinding = new JUPanelBinding("FormCreateUnitView1PageDef");
when the internal frame is getting closed the panel binding is released:
public void doDefaultCloseAction() {
_popupTransactionDialog();
panelBinding.releaseDataControl(); statusBar.release();
MainFrame myFrame = (MainFrame)this.getDesktopPane().getParent().getParent().getParent().getParent();
myFrame.getJMenuUnitVoc().setEnabled(true);
super.doDefaultCloseAction();
Why I’m asking about this is because I met another syntax which is known to be commonly used:
Something like this:
this is the code I use to (re)create the panel,
the setBindingContext method.
public void setBindingContext(BindingContext bindCtx)
String detail2BCName = "myName";
if (bindCtx.get(detail2BCName) == null)
DCBindingContainerDef bcdef = (DCBindingContainerDef) JUMetaObjectManager.getJUMom() .findLoadedObject("mypackage." + detail2BCName);
DCBindingContainer bc = bcdef.createBindingContainer(bindCtx);
bc.setName(detail2BCName);
bindCtx.put(detail2BCName, bc);
// ... then calls to jbInit etc.
this is the code I use to release the binding when
the window is closed
getPanelBinding.release();
getPanelBinding.getBindingContext().remove(superPanelBinding.getName());
…but this syntax is badly documented, so I’m a bit confused about which is right… my code works pretty fine (all master and detail frames are synchronized and all that…) except for one issue I’m going to describe.
I’m waiting for your opinions….please help make it clear.
THE MAIN PROBLEM
2. I’ve got a master/detail internal frame. When I make any changes in it and then commit them through a navigation bar I get the following exception as I try to close it later through the standard close icon:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

… few things
-1. If I commit a transaction through the popup dialog the exception doesn’t emerge.
-2. If I remove the “panelBinding.releaseDataControl(); statusBar.release();” from doDefaultCloseAction() method the exception doesn’t emerge but then I get another well-known exception as I try to reopen the internal frame.
-3. If I debug doDefaultCloseAction() method step by step the exception doesn’t emerge.
-4. Finally…. the exception doesn’t suspend the application it just goes on as if nothing has happened (the stack is only displayed on the console).
I learned about one similar problem here:
JClient Threading Bug in JUCtrlAttrsBinding?
but the bug described has been fixed in ver 10.1.3.3.
I'm using Jdeveloper 10.1.3.3
So, please ...please…please help me overcome it.
Best regards. Alex.

Sorry for being a bit annoying...
But .... no one has answered my question yet......though you promised...
Eventually I’ve somehow solved the trouble by replacing the “ panelBinding.releaseDataControl ” with
“ panelBinding.release(DCDataControl.REL_VIEW_REFS)
panelBinding.getBindingContext().remove(panelBinding.getName());”
In the doDefaultCloseAction() method
it seems like it works good now.
I reconstructed a bit my code
Now I’m invoking the internal frames this way:
private void jMenuDeptVoc_actionPerformed(ActionEvent e) {
FormCreateDeptView deptVoc = new FormCreateDeptView();
this.getJMenuDeptVoc().setEnabled(false);
deptVoc.setBindingContext(panelBinding.getBindingContext());
this.deskTopPane.add(deptVoc);
I looked through the following how to:
http://www.oracle.com/technology/products/jdev/howtos/10g/jcmultiform/index.html
there is an additional method there, which is invoked before creating a new frame where the binding container for the panel binding is created:
private void createDetailBinding()
String detailBCName = "DetailFormUIModel";
if (panelBinding.getBindingContext().get(detailBCName) == null)
DCBindingContainerDef bcdef = (DCBindingContainerDef)JUMetaObjectManager.getJUMom().findLoadedObject("sample.DetailFormUIModel");
DCBindingContainer bc = bcdef.createBindingContainer(panelBinding.getBindingContext());
bc.setName(detailBCName);
panelBinding.getBindingContext().put(detailBCName, bc);
But since createBindingContainer(BindingContext) method has been deprecated in 10.1.3 i skipped this step.
Nevertheless my program is working now I still wonder if the way I’m doing it is right.
Thanks. Alex.

ADF Swing Deployment problem

Hi,
I have an ADF Swing project completed.
I can run my application from Jdeveloper 10.1.3.3 successfully.
Now we are ready to go to production.
I want to generate a simple JAR file which can be called like - java -jar MyApp.jar
To generate MyApp.jar:
1) I have created a new group in the deployment profile file and specify to add the Manifest.
2) I added all the jars found in my application log file (the logs when jdev run my app.).
3) I Specify the full path to my MainForm.class
4) I have added all my classes
5) Finally I generated to JAR from jdeveloper
6) I copied the MyApp.jar into the JDK\bin folder of my Jdeveloper (to avoid potential java version conflict)
Problem: When I try to run my app from the JDK\bin folder with java -jar MyApp.jar, I got the error Exception in thread "main" java.lang.NoClassDefFoundError: .....
My question is : Does anybody either successed in deploying an ADF Swing application using Jdeveloper. If yes, how?
I have read dozen of articles from this forum, nobody seemed to successed deploying ADF Swing application.
Thanks.
houevoton.

Gentlmen, thank very much.
I have made a big progress.
First, I have deploy a simple form based on Steve's scenario. It works fine. I learn from this the role of each type of File Group in a deployment profile.
I also read and dowload the following show case http://verveja.footsteps.be/~verveja/files/oracle/JarStuffThread615655-v0.01.zip
It works fine. I get how to include an external jar in my deployment file.
However, I am still having a small problem with my generated JAR.
In fact my workspace has 3 projects.
1- AppUtils.jpr contains my utility classes (date utilities, system constants, etc.)
2- Model.jpr contains BC entities, views objects and the AppModule.
3- View.jpr where my forms and panels are.
All those 3 projects are in the same workspace, which is slightly diffrent from the example of the show case above.
I created a deployment profile and add two File Groups:
- The first group is simple "Packaging" group and I check all utilities classes required in my application.
- The second one is a "Dependency Analysis" group following process described by Steve.
When I generate and run MyApp.jar, I get error [b]JBO-30003: The application pool (full.path.AppModuleLocal) failed to checkout an application.
Since yesterday I was struggling with this. I am not able to understand why this message.
My AppModule is well configured with credentials to connect to the target database. I tested it and it is ok.
I can run the application from within Jdeveloper without trouble.
Once again, I need your help.
Thank in advance.

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.

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;

NullPointerException in ADF Swing bassed application

Hello, i have an ADF Swing based application. In close window events of JFrames it executes the next code:

frameInstance = null; //3
Where frameInstance is a static reference to the current JFrame object and panelBinding is the reference to the JUPanelBinding autogenerated by the framework.
When line number 2 is executed it throws a NullPointerException:

Thanks for your help Frank. I've changed and invoque methods this way:

Now, its works but when executes the _popupTransactionDialog() method (caused trying to exit whitout save changes, and then appears the "Commit Rollback Window") the Exception appears again. I've commented the panelBinding.releaseDataControl() line and the NullPointerException dissapear...

Deploying a BC4/ADF Swing Application to a JAR File

Hello,
what do I exactly have to do, to deploy an ADF/Swing/Business Components-
Project-Application to a JAR File. I can not start it outside the JDevloper IDE,
but I created a deployment profile and deployed it to a JAR.
There is always the error "Could not find the main class", when starting the
JAR. In the JDeveloper IDE the application is running, and I also defined a "main class" there.
Could anybody help me please?
Greetings.

You need the ADF runtime libraries in your classpath or as part of your JAR.
Have a look at the command that JDeveloper is using to run your project (it is in the log window) and copy the classpath defenition provided there to the command line you use.

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.

ADF BC in ADF Swing application(global datasource connection)

Hi all!
I have ADF-Swing based application.
I have a standalone Weblogic server and global datasource (for example, name of datasource hrGlobal)
I want to use this datasource(hrGlobal) in my application module. All my entities and views must connect into the database, using this datasource.
The question is, how can I declare this remote connection in connections.xml, for using him in Application Module?
In forum or in documentation a can't find the answer for this question. So, any help is welcome:)
Thank you all for responses.
PS. JDeveloper version is 11.1.1.3
WLS version is 10.3.3

Thank you for links. Also, I found very useful link http://suns1988.blogspot.com/2011/02/adf-desktop-application.html
So, I had deployed application on WLS. Ear size is 95 MB with folder adfjars, that includes many jar libraries.
Now I'm trying to run WebStart file, but get an error "com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: http://myurl:myport/testWebStart/adfjars/xmlparserv2.jar".
Can you help me, please?
And the 2-d question is about libraries in folder "adfjars": Can I share this libraries on WLS, than not to deploy each time in Ear archive?

ADF/Swing/JClient application migration problem from 10.1.3.5 to 11.1.1.3

Hi,
I am migrating an application from JDev 10.1.3.5 to 11.1.1.3 in order to deploy it to a java 1.6 JVM which is only certified with JDev 11.1.1.3
No matter what I do the DataBindings.cpx file content is emptied by the IDE, the migration was successful => no errors displayed.
I tried to solve the problem by doing the following but the file stays empty:
1) the removing the project from the application and adding it again, migration is done again => FILE EMPTY
2) adding manually the content in the source file then running XML validation => no errors, I close the file, reopen it and EMPTY AGAIN!
Your is needed and will be appreciated!
Thanks
Fred

Ok it seems I have resolved my problem see end of thread
Still have following relevant question for an Oracle team member:
Why is my <pageMap/> empty in my migrated application cpx file?
=> when I create a new ADF Swing application this tag is not empty:
in new file:
<pageMap>
<page path="view.PanelPhotolabVO1" usageId="view_PanelPhotolabVO1PageDef"/>
</pageMap>
<pageDefinitionUsages>
<page id="view_PanelPhotolabVO1PageDef"
path="view.pageDefs.PanelPhotolabVO1PageDef"/>
in migrated file:
<pageMap/>
<pageDefinitionUsages>
<page id="PanelWeventEditParamVO1UIModel"
path="com.photoswing.view.web.PanelWeventEditParamVO1UIModel"/>
Solution to empty migrated cpx file:
It seems the migration utility couldn't cope with the BC4JDataControl definitions, so I edited them manually.
Example of 10.1.3... syntax:
<dataControlUsages>
<BC4JDataControl Configuration="BaseTablesAMLocal"
Package="com.xxx.model.system"
xmlns="http://xmlns.oracle.com/adfm/datacontrol"
id="BaseTablesAMDataControl"
FactoryClass="oracle.adf.model.bc4j.DataControlFactoryImpl"
syncMode="Immediate">
<Parameters>
<Parameter name="FactoryClass"
value="oracle.adf.model.bc4j.DataControlFactoryImpl"/>
<Parameter name="SupportsFindMode" value="true"/>
<Parameter name="Configuration" value="BaseTablesAMLocal"/>
<Parameter name="SupportsTransactions" value="true"/>
<Parameter name="Package" value="com.photoswing.model.system"/>
<Parameter name="SubType" value="DCBC4J"/>
<Parameter name="Name" value="BaseTablesAMDataControl"/>
<Parameter name="id" value="BaseTablesAMDataControl"/>
</Parameters>
</BC4JDataControl>
New syntax:
<BC4JDataControl id="BaseTablesAMDataControl"
Package="com.xxx.model.system"
FactoryClass="oracle.adf.model.bc4j.DataControlFactoryImpl"
SupportsTransactions="true" SupportsFindMode="true"
SupportsRangesize="true" SupportsResetState="true"
SupportsSortCollection="true"
Configuration="BaseTablesAMLocal" syncMode="Immediate"
ExceptionMode="Immediate"

Tip:
Do this editing outside JDev with ide closed to avoid crashing it.

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

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?

How to change text in header of ADF Swing JTable?

I need to change texts in ADF Swing JTable header.
any clue?
thanks
Branislav

Hi,
how do you need to change it? Dynamically or static. If static then - assuming ADF BC is the underlying model - you can set the label hint to override the default column naming. If not using BC, you can set the label in the ADF binding as well.

ADF Faces + hardware device in the client side.( adf swing or adf java fx)

We are using adf+swing in desktop app.
We like ADF Faces but we need interations with Hardware device in the client side: scan reader, web cam, bar code reader, finger prints reader …
How to do that’s in the adf faces web environment ( what about with sandbox security) how to obtain in the adf faces web page in the client side de video streams.
In the future adf will be use Java FX?
Thanks
Juan Carlos Llanes

Hi,
see sample 71 http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples
You can use ActiveX plugins or JavaApplet to access the client system. To reach out of the sandbox, it will require a certificate
In the future adf will be use Java FX?
No.

ADF Swing Graph Issue

Hi,
I am working on ADF Swings where i need to drag and drop the Data controller as Graph. I have Created a Datacontroller and Drap and Drop it as the Graph. I am able to see the Graph (BigGraphDef.xml is created). I am not able to set the o1, y1,y2 axis values for the graph . I am using JDev 11.1.1.3.
Any Pointers in this regard will be highly helpful.
TIA

Can any one reply to the above question?
