ADF Error Handling
Dear Steve Muench,
Iâve studied your Toy Store Demo Application so I could apply your way of working to handle errors in my ADF-application.
But the problem is that itâs quite difficult for me to understand it all.
It would be very helpful if you would explain it to me in some steps. Iâve read your documentation of the Toy Store Demo, but didnât understand it all. Maybe itâs because Iâm only a beginner.
Iâve already had contact with you on the Oracle forum for other questions and Iâm hoping you can also help me with this one.
Best regards,
Robbie Vanhove
You can refer to the JavaDoc for the Struts HTML errors tag for more information on how the <html:errors> tag works.
http://struts.apache.org/userGuide/struts-html.html#errors
In a nutshell,
The struts <html:errors> tag has two ways it can be used.
<html:errors/>which displays all ActionError objects in the ActionErrors collection, and...
<html:errors property="SomePropertyName"/>which only shows the ActionError objects that have be constructed with the specific property name.
There is a specially-named property that identifies "GLOBAL ERRORS", it's a string defined by the constant GLOBAL_ERROR in the Struts ActionErrors class.
Next to different fields, you'll see that the ADF toy store JSP implementation uses the property name that matches the name of the ADF binding (whose name matches the name of the underlying view object attribute).
To show global errors at the top of the page, it uses the special string name given by the constant just described.
The customized error reporting logic in the ToyStoreDataForwardAction class basically is pulling apart the "tree" of bundled ADF exceptions and constructing ActionError objects for each interesting error that it finds. Errors that are specific to a given attribute are constructed with that attribute name so they will be "selected" by the <html:errors property="ThatAttrName"/> tag.
Errors that are not specific to a single attribute are created as global ActionErrors.
That's a quick brain dump.

JDeveloper 11.1.1.5
I'm tring to handle errors to avoid showing java stack trace, SQL, and instead show user friendly messages.
(A) To handle errors in the model layer I setup DataBindings.cpx by I adding as ErrorHandlerClass="package.MyDCErrorHandler" that extends DCErrorHandlerImpl.
Inside MyDCErrorHandler I simply log the exception then throw a new JBO exception with a generic "Unhandled error call customer support" message instead of the exception message.
(B) On the task flow I created a method and marked it as exception handler as descibed here.
http://andrejusb.blogspot.com/2011/03/exception-handler-for-method-calls.html
http://andrejusb.blogspot.com/2011/03/exception-handler-for-method-calls_19.html
I do similar logic here, log the exception then show generic faces message "Unhandled error call customer support"
Is this a good methodolgy?
This seems to work fairly well but ocassionaly an exception slips through and shows default error message.
I'm now looking at this option
http://blogs.oracle.com/jdevotnharvest/entry/extending_the_adf_controller_exception_handler
How does this compare to extending DCErrorHandlerImpl(A) and task flow exception handler method(B)?
I note that this option uses Throwable instead of Exception. Will this handle java errors (like OutOfMemory)?Hi,

Actually the default ADFc Exception handler does not listen for all kind of exceptions but only those that can be handled by the controller. If you have an exception that is not handled by the ADFc exception handler then you can take a chance and handle this in your own exception handler class. You would handle the specific exception you are interested the most to handle and re-throw all the rest for the ADFc controller to try and handle.
Just create a custom handler and print the exceptions you receive in there. If this prints the OOM error then you can handle it. If it isn't shown here then you cannot handle it this way

ADF: Gracefully handling JDBC connection errors? Part II
Hi gang
I while back I posted a forum post to find a solution to "display a specific web page when the JDBC connection drops out on our ADF application, specifically the following error: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection"
...you can see the original post here:
Re: ADF: Gracefully handling JDBC connection errors?
For the life of me I can't get this to work now. It appears I can't redirect to another page during the call to reportException. I've had a play with different methods of redirecting, as seen in the following code sample:
public class ErrorHandlerImpl extends DCErrorHandlerImpl {
public ErrorHandlerImpl() {
super(true);
@Override
public void reportException(DCBindingContainer dCBindingContainer, Exception exception) {
// try {
String message = exception.getMessage();
if (message.indexOf("JBO-26061") >= 0) {
// Method 1
FacesContext fc = FacesContext.getCurrentInstance();
UIViewRoot viewRoot =
fc.getApplication().getViewHandler().createView(fc, "faces/errorPage.jspx");
fc.setViewRoot(viewRoot);
fc.renderResponse();
// Method 2
// FacesContext fc = FacesContext.getCurrentInstance();
// fc.getApplication().getNavigationHandler().handleNavigation(fc, null, "goError");
// fc.responseComplete();
// Method 3 - required IOExcepition handler
// FacesContext.getCurrentInstance().getExternalContext().redirect("faces/errorPage.jspx");
} else
super.reportException(dCBindingContainer, exception);
// } catch (IOException e) {
}... with no success.
Has anyobody any other solutions or advice on getting this to work?
Your help appreciated.
Thanks & regads,
CM.
PS. JDev 11gR1 ADF BC + ADF Faces RCHi Frank
Yep, I' tried redirect, that was method 3 (you can see all 3 methods I've attempted, last 2 are commented out).
With the declarative ADFc exception handler, problem is it's a catch all, not specifically for JBO-26061. Can you think of a way I can tailor fit it for JBO-26061 with a custom message "Database down"?
In addition the exception handler is not consistently called. As example, if you're moving between pages rather than operating on 1 page, the standard af:messages error dialog is shown if the db connection has been dropped, rather than navigating to the exception handler page. As such it seems the DCErrorHandlerImpl.reportExceptions is the better chokepoint to work from.

ADF Mobile Error handling and redirect
I'm stuck on how to handle errors within my ADF Mobile application. My application consumes a number of web services and we have found we often get error messages when phone connections switch from wifi to 3g or lose connection altogether. These are errors such as SSL handshake failure, HTTP500 errors, and also errors where it can't display the binding eh "Unable to get value for the property due to invalid binding iterator" because a WS call has failed. From the little information I can find - and none of it specific to ADF Mobile, I think I need to write an error handler class which I set against ErrorHandlerClass in databinding.cpx - if that correct? Am I able to catch these errors using that method and if so has anyone got any examples at all. Ideally what I'd like to do when I've caught those errors is redirect to another page (showing something like facebooks app does when it loses a connection and says tap to try again), does anyone have any suggestions or examples?
thanks

ADF Custom error handler not working.
Hi All,
i am using jdev version 11.1.1.5.0. i have created one custom error handler class in model layer which extend DcErrorHandlerImpl class.
and do the entry in Databinding.cpx file
*<Application ErrorHandlerClass="mypackage.classname"/>*
i have override getDisplayMessage(BindingContext ctx, Exception ex) method to show SQL Exception which comes from database table trigger.
code is following-
package com.in.jagran.view.services;
import java.sql.SQLException;
import oracle.adf.model.BindingContext;
import oracle.adf.model.binding.DCErrorHandlerImpl;
import oracle.jbo.JboException;
public class AclasErrorHandler extends DCErrorHandlerImpl {
public AclasErrorHandler(boolean setToThrow) {
super(setToThrow);
System.out.println("Inside Error Handler class");
public AclasErrorHandler() {
super(true);
// this(true);
* Returns the message that will be reported to JSF for each error that occurs.
* Returning "null" is the way the custom error handler signals that a given exception
* should not be reported to the client.
@Override
public String getDisplayMessage(BindingContext ctx, Exception ex)
if (ex instanceof oracle.jbo.ValidationException) {
return super.getDisplayMessage(ctx, ex);
else {
// Extract and return the error message that has to be displayed
Exception exception = ex;
String message = "";
// If this exception is an instance of JboException,
// try to find the cause by recursing over the eventual causing exceptions
if (exception instanceof JboException)
Throwable[] exceptionList = ((JboException)exception).getExceptions();
while (exception instanceof JboException
&& exceptionList != null && exceptionList.length > 0)
exception = (Exception)exceptionList[0];
if (exception instanceof JboException) {
exceptionList = ((JboException)exception).getExceptions();
// *** Special processing of SQLExceptions
if (exception instanceof SQLException) {
message = exception.getMessage();
// Ignore the lines in the error message that indicate the line number in the PLSQL code that the error resulted on.
int ind = message.indexOf("ORA-06512");
if (ind > 0)
message = message.substring(0, ind);
// *** If the the reason for the JboException was data creation exception then display the message
// of the top JboException (i.e. JBO-*****: Invalid numeric value, date format or time format)
else if (exception instanceof NumberFormatException || exception instanceof IllegalArgumentException) {
// Report the top exception
message = ex.getMessage();
// Otherwise report the message of the lowest exception in the hierarchy
else {
message = exception.getMessage();
return message;
}but it is not working for me.
thanks in Advance.yes i have used dubugger.
i have set break point to following line-
return super.getDisplayMessage(ctx, ex);
if (ex instanceof oracle.jbo.ValidationException) {
return super.getDisplayMessage(ctx, ex);
}when atttribute validation done like i have attribute of type number and i have done the validation "must be greater than 0" now when i have given negative value control go to above line.
and i have added following code also in handler class
@Override
public void reportException(DCBindingContainer dCBindingContainer,
Exception exception) {
System.out.println(exception.getMessage());
super.reportException(dCBindingContainer, exception);
}now when i have done commit operation control go to here and println statement print follwoing error on log window.

Database Constraint Error Handling on create/edit (Struts ADF)
Hi,
In our project we use Struts ADF (JDeveloper 10.1.3) technology. And we're facing the following trouble with it.
If we try to create a record that violates say Unique constraint in the database, then during commit procedure of the AppModule's Transaction an exception occurs.
We handle this exception with our extension of DCErrorHandlerImpl. And we have to do the rollback action because the Transaction became invalid and we cannot do the commit since there was an error.
But unfortunately appModule.getTransaction().rollback(); forces ViewObj to loose all of the newly created rows. Because of this, after pressing submit with the same (violating) data once more our edit form shows the first row in a rowset.
Are there any ideas about what we may be doing wrong?
Any standard approaches on database constraint error handling?
The "before/after commit/rollback" approach is very effort-consuming because we have a lot of views in our app and tracking all of them may become a nightmare in future.
Thanks in advance.

LarryHi Steve!

Configuring the ADF Javascript error handler
I've noticed that ADF has a default Javascript error handler which seems to swallow all Javascript errors. Now this is a problem since all errors disappear into this logger system.
How can I get this logger to write error messages to the Firebug console?Hi,
please read page 23 onwards of: http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf

I'm working on a JPA/TopLink Essentials/ADF faces application. It's going well except that I don't have a clue how to get on top of the error handling. JPA doesn't seem to have any. I would assume that there must be a Toplink extension[b] to find out what errors/codes etc are being produced. ADF faces does a ok job of showing them on screen but the handling should be more user friendly for errors like invalid foreign key, unique key violation etc.
Since there is no return and no exceptions declared on JPA functions like persist(), I assume that there must be some sort of listener that I can register to handle the errors myself. If ADF Faces can get the errors then so can I, but how??
Any help would be appreciated
MarkThe "errors" raised by the persistence provider for the types of "errors" you mentioned are all runtime exceptions of the PersistenceException variety. See the javadoc for this class and also look at its subclasses: http://java.sun.com/javaee/5/docs/api/javax/persistence/PersistenceException.html
Since PersistenceException is an unchecked runtime exception, its up to you to catch it at whatever point you decide to handle these types of problems in your application (i.e. in the service layer which would communicate the problem to your view layer to display something user friendly). Make sense? -

if (mapper.canMapException(ex)) {
ex = mapper.mapException(ex);
super.reportException(bc, ex);
I got errors
DisableJboExceptionCodesMapper not fount
canMapException not fount
mapException not fountAbhilashs01,
Yes, that example from the docs appears to be missing a few things, to-wit: the ExceptionMapper class and the DisableJboExceptionCodesMapper class. Without the ExceptionMapper class, JDeveloper's import assistance is finding one in com.sun.jndi somewhere, which is obviously the wrong one. So, yes, the docs are good, but they appear to be missing some key things, making it kind of hard...
Another place to find an example error handler class is in the Fusion Order Demo: http://www.oracle.com/technology/products/jdev/samples/fod/index.html

Hello,
I am using Build JDEVADF_11.1.1.2.0_GENERIC_091029.2229.5536
I defined the custom error handler as mentioned in the ADF development guide.Facing weired issue when AM method is called from task flow.
e.g,
AM method
public showSuccessMessage(){
this.getDBTransaction().addWarning(new JboWarning("Hello Sample message from AM"));
Above method is called from taskflow and corresponding action is specified in the page.I have task flow ErrorHander activity defined for the task flow also.When I click the button to call the AM method,Jbo warning raised in AM and catched by the task flow error handler and after this control is passed to CustomErrorHandler and message shows properly.But this happens only first time.After that control never goes to custom error handler. Am I missing some thing??
Any idea why??
Thanks
RBHi Frank,
Thanks
What I noticed is,
Case:1
when warning is raised using the addWarning api from AM, binding layer throws exception of type Warning,catches in task flow error handler and directly goes to get getDisplay message method of the custom error handler which is defined in databinding.cpx only once.After that it catches in taskflow error handler and never goes to custom error handler defined in data binding.cpx
Case2:
When I raised it as throw new JboException flow goes reportException of custom error handler and which calls the getDisplay message.In this it even not going to task flow error handler.
If you can confirm this is expected behavior or it is bug that would be great,it helps us define the exception handling framework.
Thanks

Error Handler and Page Bindings
Hi,
I have a task flow with an error-handler defined. Any action-binding method calls which throw exceptions from the business layer are handled nicely by the error handler. The same doesn't happen though when the binding is in the page, tied to a button (as created when you drag a method from the data control palette onto the page). The exception is instead displayed in the calling page. What am I missing here?
Thanks,
Barry.Hi,
the ADF Controller catches excptions occuring while it processes an activity. If JSF catches the exception then this does not involve navigation and therefore the message displays on the page

How to take control back from service error handler in osb
I am using osb to send data to multiple services at the same time.since x query is a procedural language if any single operation fails the flow goes to service error handler which calls a BPEL webservice and logs the error in a database but the control doesnt comes back to my code I have tried everything including RESUME,REPLY operations but all in vain similarly i cannot use service callout call to my business service because its not allowing to select my BPEL wsdl operation
If your statement "the control doesnt comes back to my code" means you expect that your xquery will continue in processing than your expectations are just too high. :-)
Resume action is supposed to resume the next action in the message flow. It means the action that follows the action which caused an error. -
Report and Alert don't executed in the error handler with a JMS proxy service
Hi,
I'm working with OSB 11.1.1.4.0 and I'm facing a problem with the error handler of my JMS proxy service.
My error handler contains two main elements :
- a Report action
- an Alert with a JMS destination defined
When the business service failed the message remain in the queue. It's the expected behavior.
The problem is :
- the report is missing
- the alert is raised but missing in the JMS destination defined in the Alert setting.
I've noticed if I add a Reply with Failure or Success, Report and Alert are successfully executed.
Unfortunately the message don't remain in the JMS queue.
What can I do in order to have my report/alert done and the JMS transaction rollback in order to keep the message in the queue ?
I've already met this problem in the past with alsb v3 and my solution was to add Service Callout in the error handler in order to externalize these actions.
This solution is not convenient and I hope another solution is possible.Inventorying workgroups can be difficult, especially when it comes to remote access and network security. Because workgroups are not centrally managed, some of the items discussed in this
wiki article on preparing your workgroup environment may require you to visit each machine individually.
For non-domain credentials, you do not use the <systemname>\<user> format, you simply enter the user name. Regarding how to enter the credentials, if you have an account that uses the same username and password on all machines and is an administrator
on all of those machines, then you can enter that in the All computers credentials page of the wizard. You can also do this if they are different user names. However, if some machines have an account with the same user name, such as Administrator,
but different passwords on each machine, you will need to use the Manually enter computer names discovery method, and then enter the information for each group or each machine.
As you can tell, workgroup environments can quickly negate any benefit that the agentless inventory nature of MAP provides.
