EDT custom exception handler

Hi,
Is there any posibility to add custom exception handler to EDT? I'm thinking to implement an automatic feed-back from a client aplication. When an exception occurs in EDT it will automatically send to server. The problem is that unsigned webstart application have no permissions to call Thread.setUncaughtExceptionHandler() on EDT.
Is there any workaround?

Problems with Custom Exception Handler

Hi,
I have defined a custom exception handler for my workflow (WebLogic Platform
7).
I have a workflow variable called 'count' , which gets incremented for every
time an exception occurs.
The exception handler checks if the count is less than 3(using evaluate
condition),
if yes then it executes the action "Exit Execption Handler and retry"
else
it executes the action "Exit Execption Handler and continue"
The Workflow simply hangs, nothing on the console , the worklist from which
i call it hangs too.
Has anyone managed to use this kind of exception handling?
Thanks in advance,
Asif

Is the 'misscfm.cfm' file somewhere in the
'd:\wSites\GBMain\html\CFMS\'
directory. I will presume this is the 'web root' as defined
in your web
server (IIS or Apache or built-in or ???). The missing
template handler
file needs to be in the ColdFusion root. This is going to be
a
directory such as
'{drive}:\JRun4\servers\{server}\cfusion-ear\cfusion-war\misscfm.cfm'
for J2EE flavors OR '{drive}:\CFusionMX\wwwroot' for Standard
I think.
It has been a very long time since I have dealt with
Standard.
This is probably completely different from the above web
root. That is
the point I am trying to get across. ColdFusion has TWO roots
where it
will look for a CFML file. But the Missing and Sitewide
templates can
only be in the ColdFusion root listed above, they will not
work in the
web root.

Webservices and custom exception handling

hi all,
I have one ejb method which promote as webservices.
@WebMethod

my Custom Exception class STARS21BOException extends from EjbException and it has no-arg constructor.
but when i deploy on server i get following exception.
if i remove throws clause from method, it is working fine.

}As per method signature it is asynchronous web service however you are trying to throw soap fault. Isn't the soap fault is also a kind of response?
Do you really want your web method to be asynchronous?

Custom code as an exception handler not working.

Hi,
I worked on Custom Handler for unauthorized access to a taskflow following the link below and it worked. But a special case in this doesn't work.
http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/taskflows_complex.htm#ADFFD22602
Scenario-1: I have a link that opens an unauthorized taskflow as blank page. I tried the solution of custom handler and am able to display message or display error page --- WORKS FINE
Scenario-2: I have a link that opens an unauthorized taskflow in a pop-up as blank page. The above solution doesn't work. I tried displaying SOPs but nothing gets print --- DOESN'T WORK.
Details:
The custom handler doesn't work with Pop-ups. I have an unauthorized taskflow that gets called inside a pop-up using a link. Being an unauthorized user, I click on the link and it pops-up with a blank page. As per the custom handler it is supposed to display error-page. But it doesn't.
I tried displaying SOPs inside the handleException method and nothing prints. The exception handler is unable to catch the exception. If this use-case throws some exception, my exception handler would have handle it but it doesn't raise any exception.
Is this something issue that I need to discuss with FMW team?
Any workaround for this would be of great help.
Code Sample:
public void handleException(FacesContext facesContext, Throwable throwable,
PhaseId phaseId) throws Throwable {
String errorMessage = throwable.getMessage();
if (errorMessage != null && errorMessage.indexOf("ADFC-0619") > -1) {
setEL("#{sessionScope.errorMessage}",
"You are not authorized to view this page.");
ExternalContext externalContext =
facesContext.getExternalContext();
externalContext.redirect("ErrorPage");
} else {
super.handleException(facesContext, throwable, phaseId);
Thanks
Raza

Hi Frank,
This scenario is not specific to a particular TaskFlow. In General, there are links in some views, that invokes taskflows and a particular user may not have permission to that TaskFlow. In this scenario, I am not sure where I need to define the method or router. And Hence I registered the Custom Exception Handler as a service as per the documentation.
But the logic in documentation doesn't work with Pop-ups.
Thanks
Raza

Exception Handling in Web Center for UI related Errors not working.

Hi Guys,
I have implemented Error Handling in ADF Application with Custom Model Exception Handler ( which is "CustomExceptionHandler extends DCErrorHandlerImpl") to catch all Model Layer Exception and to customize those error messages.
I have implemented Error Handling in ADF Application with Custom View Exception Handler ( which is "CustomViewErrorHandler extends oracle.adf.view.rich.context.ExceptionHandler";) to catch all View Layer Exception and to customize those error messages.
The design for this is , in Model Custom Exception Handler i find the exception message in "public String getDisplayMessage(BindingContext bindingContext,Exception exception) " method and throw RuntimeException to pass this exception to Custom View Layer Exception , so that i can handle all the exception @ View Layer it self .
In the View Layer Exception Handler i am navigating to specific error page using
String contextPath = ((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest()).getContextPath();
ExternalContext ectx = facesContext.getExternalContext();
ectx.redirect.
All these things absolutly working in ADF Application for all the exception ( Model , View ) and i am successfully navigating to error page.
Problem :
When i implement the same thing in Webcenter Application ( Model Custom Exception Handler and View Custom Exception Handler), Model Part is working as expected , but View Custom Exception Handler is not all calling .
i am assuming that ,this View Custom Exception Handler (CustomViewErrorHandler extends oracle.adf.view.rich.context.ExceptionHandler) works only for JSF Life cycle
"Allows frameworks to intercept otherwise unhandled exceptions thrown during the JSF lifecycle. ExceptionHandlers can be registered by adding a service file with a class name at META-INF/services/oracle.adf.view.rich.context.ExceptionHandler." from http://jdevadf.oracle.com/adf-richclient-demo/docs/apidocs/oracle/adf/view/rich/context/ExceptionHandler.html";
As Webcenter Portal uses ADF Life Cycle this Exception Handler is not calling , i am not sure.
if any one has any idea please let me know .
Thanks

Struts exception handling - Exception handler

Hi ,
I need some help for struts exception handling . Global exception is working fine in my struts application . But I need to show the exception stack trace also in the screen whenever the exception occurs.I guess this can be achieved if we use a custom exception handler instead of struts default exception handler . Can anyone please provide me a sample code to deal with a custom ExceptionHandler class ?
Thanks in advance...
Regards,
BG

The struts provides org.apache.struts.action.ExceptionHandler class for creating the custom exception handlers. All the custom Exception Handlers should extend the ExceptionHandler class and override the execute() method.
//An Example
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ExceptionHandler;
import org.apache.struts.config.ExceptionConfig;
public class CustomExceptionHandler extends ExceptionHandler {
public ActionForward execute(Exception exception, ExceptionConfig config, ActionMapping mapping, ActionForm formInstance,
HttpServletRequest request, HttpServletResponse response) throws ServletException {
try {
// TODO CustomeCode
System.out.println("Exception Handler for the specific error");
}catch (Exception e) {
return (super.execute(exception, config, mapping, formInstance, request, response));
Struts-config.xml File
<exception key="error.system" type="java.lang.RuntimeException"
handler="com.visualbuilder.handler.CustomExceptionHandler" path="/index.jsp" />
Note:- This will transfer the control to the index.jsp after calling the exception handler. In the struts-config.xml we are adding the global exception for RuntimeException. You can add any exception like the previous example to some actions only.
I have taken this example from following link. You may visit it.
http://www.visualbuilder.com/jsp/struts/tutorial/pageorder/38/
I would like if you share knowledge with me.

Exception handling in Custom Login procedure

Hi,
I have a custom login procedure. Now instead of handling the possible exceptions in a custom way too, I want to use the syntax of the exception handling API (probably the one in the PDK) the default login procedure uses. Can someone point me to the values the default login procedure uses?
Thanks, Tony

Tony,
The default login page (the source of which is now unwrapped in 3.0.0), uses the following snippet of code to report the errors:
if p_error then
wwerr_api_error_ui.show_inline_html;
end if;The errors are stacked when the ls_login procedure is executed, and the next time the login page is called up, it just displays the stacked errors.

Implementing Exception Handling Application Block in custom web parts, event receivers

hi,
I am currently implementing try {} catch(Exception expp) { throw expp;} to handle exceptions in my intranet appln.
I have several custom web parts, event receivers, few console applciations as timer jobs etc. If i want to implement a robust exception handling what should be the approach. by searching, i saw, ms patterns n practices provides the
appln blocks.
But I think[ pls correct me if i am wrong ] those appln blocks are meant for asp.net applns ONLY.
if not, anyone has implemented those appln blocks in SP development? if yes, can anyone provide one sample / link to implement Exception Handling in SP.
help is appreciated!

Exception Handling with Custom Tags/Exceptions

Hello all --
          I'm looking for some guidance in handling Custom errors in my app. I can't
          seem to find the message string of my custom exception when trying to call
          my JSP Error page. I'm consistently getting:
          javax.servlet.jsp.JspTagException: runtime failure in custom tag
          'CalendarHandler' .
          I am using custom JSP tag libraries to process logic on my EJBs. When I
          reach an error in business logic I raise a custom exception and propogate
          this back up to doStartTag:
          public int doStartTag() throws JspException {
          CalendarProcessor cp = new CalendarProcessor();
          try {
          String eventAction = getEventID();
          // pageContext contains information for the JSP;
          // Initialize the page with the current context and session
          cp.init(pageContext.getServletContext(), pageContext.getSession());
          HttpServletRequest req = (HttpServletRequest)pageContext.getRequest();
          cp.processRequest(req, eventAction );
          } catch (CalendarException ce) {
          throw new JspException(ce.getMessage());
          return SKIP_BODY;
          Then, in my JSP, I am enclosing the TagHandler in a try...catch block; I
          can't catch CalendarException because it is Throwable and conflicts with
          JspException.
          <% try { %>
          <gtc:CalendarHandler eventID="updatecal"/>
          <% } catch (Exception e) {
          throw e instanceof JspException ? (JspException) e : new
          JspTagException(e.getMessage());
          %>
          many thanks in advance!
          s.

Exception Handling In Struts, Declarative, programatic and customized excep

hello .
I'm workingon exception handling in struts , i executed the gobal exceptions.
In glabal exception handling , one will not get the root cause of exception , rather we print the message from resource bundle.
How to get the root cause of exception in jsp page.

11g: Custom error handling for all application raised exceptions?

Hi,
the only thing I can find in the documentation regarding an error handler is this: http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/web_adv.htm#BABEHFHI (26.8)
However, this kind of error handler seems to ignore exceptions thrown in backing beans and underlaying business logic inplemented in app modules.
Is there a way to globaly handle those exceptions and show an error message if an exception is throw or is the only way a catch block in each backing bean method?
Thanks

So, If I understand correctly, the only option is to redirect to exception handler view and show eror informatin there.
If, however, we want to present errors in popup messages, we have to handle exceptions in all backing bean's methods, e.g.:
catch (Exception ex){
handleError(ex);
public void handleError(Exception ex){
FacesContext fctx = FacesContext.getCurrentInstance();
FacesMessage message=
new FacesMessage(
FacesMessage.SEVERITY_ERROR,
"Error",
ex.getMessage());
fctx.addMessage(null,message);
Is that correct?
Thanks

Best Practice for Implementing Exception Handling in BPEL

Hi All,
what is the best practice and the approach to follow Exception Handling in BPEL.
1) Do we need to implement Exception Handling in BPEL as we do in Java, means
     method 3 throws error to method 2 (if any) and
     method 2 throws error to method 1 (if any) and
     finally method 1 throws error to the main Class.
If we replicate the above scenario to BPEL
In BPEL main Scope have Custom Fault, Catch ALL
     Each Invoke is surrounded by a Scope Activity with Remote Fault, Binding Fault & Custom Fault
and follow the paradigm of Java, assuming we have Inner Scopes
     [ OR ]
2) In BPEL main Scope have all exceptions defined like
     Remote Fault,
     Binding Fault,
     anyOther System Fault (selectionFailure / forcedTermination),
     Custom Fault (if required) and
     CatchALL
     and also
     each Invoke is surrounded by a Scopes Acitivity with Custom Fault (business fault) exception Handling
I feel 1st one may not be a good practice, may be i am wrong...
Any Suggestions from experts.
Thanks in Advance
anvv sharma

Hi-
In you can create different scope and use catch branch to catch binding, remote, custom faults, business faults etc. If an error happens in a scope it will not move to the next scope( eg: you have 3 scope, error occured in 2nd scope then it will not propogate to the 3rd scope. One thing to be noticed here is your transaction in the 1st scope doesnt gets commited when an error happens in 2d scope).
You can have a catch all to catch error which are not being caught at catch level. So if any error happens which is not defined in catch block then then it will be caught in catch all branch.

Exception handling for Null/Incorrect input parameters

Hi,
My BI Publisher report has input parameter name as <region>. It is a text field and is mandatory parameter.
But if I run the report without giving value to the parameter it gives the error "The report cannot be rendered because of an error, please contact the administrator."
How can I handle this scenario so that User defined message is displayed, asking user to give correct input.
I am using Oracle BI Publisher 10.1.3.3.3
Is there some documentation available for Exception Handling/How to display User defined messages in case of error?
My requirement is that after displaying the error message (say for example "Please enter Region name"), the report processing should stop there only and it should not display the blank pages of the rest of the PDF template.
Thanks in advance.

Hi,
Thanx for the solution.
I have another query linked to this issue. My requirement is that after displaying the error message (say for example "Please enter Customer name"), the report processing should stop there only and it should not display the blank pages of the rest of the PDF template.
Thanx in advance.

Exception handling for mis-addressed messages

We are using ebXML messaging in WLI. In many of our workflows we start new conversations with trading partners based on the contents of address fields in the messages. Now and again during development a message comes in which is addressed to a TP who doesn't exist. The message fails to be sent and rolls back repeatedly. Is there a simple way to remove these messages from the WLI hub? Can exception handling be used to move messages which are failing to enter the workflows to a special queue automatically?
thanks
Ben

Hi Holger,
I will not translate the coding into VB. So if you want to do this it is OK with me.
An idea would be after some testing by the community to provide the functionality as a DLL. This way it could also easily be added to a VB project.
However I assume that some developers prefer to integrate the coding themselves so that they might add additional customer specific functionlity.
For example not to raise an exception if a specific error is in the return parameter because they want to ignore it.
Best regards,
Andre
