Throw JBO exception from doDML method-urgent HELP

Hi,
I am catching an exception on deleting a parent record without deleting a child record(FK constraint) in doDML delete operation method,when i am throwing a JBOexception with a custom message with in the catch block it is not refelecting in the front end,how can i display the FK contraint as a custom message in the front end?
however i was able to throw a jbo exception in TP2 with in the doDml method,which was displaying to the front end.
im using ADf TP3 11g
-regards

Hi,
a similar question was posted last week. I replied saying that TP3 is supposed to work as TP2. If this isn't the case, please wait for TP4 to verify if the problem still exist and if, post another message with a reproducible testcase. TP4 will be out soon

Is it possible to throw an exception from run method of a thread?

Is it possible to throw an exception from "run method of a thread"(implemented as runnable implementation)?
Is it advisable to do so?

Is it possible to throw an exception from "run method

implementation)?Yes, an unchecked one. Runtime exceptions.
Is it advisable to do so?If you mess up it happens automatically. But basically: no.

Throwing jbo exception from AppModule class

If a JBO exception does not appear on the JSF page when thrown from the AppModule class, what are some things that should be checked?

Jaime,
I'm not really sure what your question is, but backing beans would generally be considered part of the controller layer, in my opinion.
JBO exceptions are typically raised from the Model layer.
What exactly are you trying to do here? Can you share the use case?

Throwing an exception from XSLT

Just wanted to share a finding with the Oracle XDB community and possibly suggest an enhancement to the xdb product development team (care of MDRAKE).
I had a scenario where I wanted to throw an exception from the XSLT.
A little Googling revealed this helpful post:
http://weblogs.asp.net/george_v_reilly/archive/2006/03/01/439402.aspx
...so I gave it a shot.
In my XSLT, I have a <xsl:choose> block with the following <xsl:otherwise> block:
<xsl:otherwise>
    <xsl:message terminate="yes">Unknown Document Type</xsl:message>
</xsl:otherwise>I used a stub test to run this through, giving it a file which would exercise the exception:
select xmltype(bfilename('XML_RESOURCES', 'data.xml'),0).transform(xmltype(bfilename('XML_RESOURCES', 'sanitize_xml.dev.xsl'),0))
from dual;..and to my 'joy', I did get an exception:
ORA-30998: transformation error: execution of compiled XSLT on XML DOM failedHmm...would of been nicer to get something like what Eclipse/Xalan pops out:
file:/H:/eclipse_indigo_workspace/XSLT/sanitize_xml.xsl; Line #28; Column #59; Unknown Document Type
(Location of error unknown)Stylesheet directed termination...i.e. my custom error message "Unknown Document Type" isn't output by Oracle.
Just to be safe, I tried a file which would NOT exercise this xsl:otherwise block and it did run through OK.
So, could XDB report a better error?
Thoughts?

Now with respect to message the question is where...
We 'could' output into the same buffer as is used by DBMS_OUTPUT, but that has limits in terms of the amount of output that can be generated.
We could write it to the trace file, but that may be difficulat for a developer to get to
We could write it to a log file in the XDB repository, but where and how to name it...
We could another parameter to XMLTransform, which would be a Message Buffer
All of these are in effect enhancements..
BTW I checked with XML Spy and they seem to ignore message too, so I'm wondering how widely used this is...
We cannot add it to the output of the XSL since XMLTransform defines the output of the XML to be well formed XML, and adding a random set of text nodes would viloate that rule..

Is it possible to throw an exception from a handler chain with JAXWS???

I know I cannot throw directly an exception from the handler cause my handler extends SOAPHandler and the method handlerMessage cannot throw exceptions. The problem is that I would like to validate some authorization and if the client doesn't have the appropriate rights, I would like to throw an exception from the handler without calling the web service itself, so the client would receive a valid soap response from the server. Is it possible?? Is there another mechanism that I can use to do that??
Thanks a lot
Korg

You can throw a ProtocolException or RuntimeException from handleMessage().
If you throw ProtocolException, HandleFault() is called on previously invoked handlers.
If you throw a RuntimeException, handleFault() or handleMessage() is not called on previously invoked handlers, and the Exception is converted to Fault message and dispatched.

Raise customized JBO exception from AM to Client

All
I want to raise exception in am, vo or eo to client side when some kind of business rules hit. How can i raise the JBO exception with info to identify the failed root reason?
If execute the binding operation I can call the getErrors() to check if the last execute succeed or not. How can i get this error message when call the operation via web service which exported from am,
follow are the code part in DemoAMServiceImpl for example, the DemoAMServiceImpl is generated by default when export DemoAM to support web service:
public EventsVOSDO updateEventsVO1(EventsVOSDO eventsVO1) throws ServiceException {
return (EventsVOSDO)update(eventsVO1, "EventsVO1");
when call this method to update event via web service to update event in AM, logic in eventEO checks the event property and raise custom event to client to indicate failure.
any one have good ideals on this requirement?

Try something like this in your method:
throw new JboException("Don't do that.", "101", null );

A problem with 3 exceptions from 1 method!!!

I don't like it and I need advice on how to avoid it. I have been given an interface and am required to use ech of its methods. Here is what happened...
The interface declares that when a record is searched for in the database and cant be found then a database exception must be thrown.
When a operation is performed on a record it gets locked with a lock cookie and this cookie must be the same when the lock is released at the end of the operation or a Security Exception gets thrown.
The file accessing itself throws IO exception which ofcourse has to be handled too.
So far I have done the following(data level). I have a general databaseException which is a parent to all database exceptions. This means my Security and RecNotFound exceptions can be caught by one exception as they bubble up the stack. My IOException gets converted to a runtime exception and will be converted back to a checked exception in the GUI layer where I cater for all exceptions (The user does not see them).
Moving on....
In my service layer layer I have a business Exception to all business logic errors. Here is why it gets tricky...
A record can not be booked if it is already booked. So I have a bookedRecException and the booking process involves locking the record(throws databaseException as mentioned). I also catch my RuntimeIOExceptions and throw them in my service layer up the stack as an IOException which gets handled in the GUI.
As you can see this does not look good and I want to fix it. I thaught of making my databaseException into a IOE my service interface methods are all throwing DatabaseException AND IOExceptions.

So what you are saying is: you don't want to deal with all the different exceptions?
No what I am saying Is it's the SCJD and I am trying to avoid messy code with 3 exceptions. I am very much for custom exceptions where having a strongly typed exception tells you enough just by the fact that AlreadyBookedRecordException in your stack explains it all.That is not apparent from you post, what you seem to be saying is that you don't want them. In any case I've never found it messy to handle all exceptions individually, nor have I found it messy to use the method I mentioned.

Getting the name of the page that throws an exception from an error page

How can I get the name of the page that throws an
error exception from an error page?.
Thanks.

In each of your jsp pages, u should set the name of page in the request object. e.g.
In jsp page called main.jsp you should do request.setAttribute("pageName","main.jsp");
Then in error page you can get the name like
String pageInError = (String) request.getAttribute("pageName");
I hope that answers your question.
thx

Throwing Runtime Exceptions from BPM. How?

Hi !
I want to make appear a red flag in the SXMB_MONI as a result of a custom condition inside a BPM. I tried with the control step, but it makes no "red flag".
Should I make a transform step between 2 dummy message types with a UDF that throws the runtime exception there?? is there another way ?? We want a red flag as a result of a expired deadline while waiting a file adapter transport acknowledgement.
Thanks !!
Matias.

Matias,
As you said before you want the BPM to be errored out if it reach the deadline, am I right. In control step if u say cancel process it equivalent to logically deleting the work items, so obviously you will get an succesfull message. What I suggest you to do is in Deadline branch - control branch select throw exception. The exception name has to be defined in Block level. So if you throw an exception it will look for the exception branch in the same block level if not the higher(super)block level, if it couldn't find the exception branch it will run out to error. Actually the exception branch is used to catch that exception and continue the rest of the process, so i think there is no need for defining the exception branch itself.
Hope it helps you!!!
Best regards,
raj.

Throw an exception from one class to another?

I have an applet that analyzes different sorting algorithms. Each sorting algorithm is a seperate class. The applet passes the sorting algorithm class an unsorted array, the sorting algorithm sorts the array, and returns the sorted array to the applet. Sometimes the sorting class will generate a stack overflow exception. How do i catch the exception in the sorting class and throw it to the applet, which can then display a dialog box. In the sorting class I have setup a try/catch block that throws the exception and in the class decleration it says "throws Exception". The code in the applet that executes the sort class is inside of at try block as well. When the prog generates an exception in the sorting class it wont throw and be caught by my applet. How can this be done?
Thanks,
Dave

StackOverflowException is not descendand of Exception class:
java.lang.Object
|
+--java.lang.Throwable
        |
        +--java.lang.Error
              |
              +--java.lang.VirtualMachineError
                    |
                    +--java.lang.StackOverflowErrorSo if you like to catch it dont declare method to throw Exception (Error class is unchecked exception so it doesn't need to be declared to be thrown). Just try to catch StackOverflow or Throwable. Good luck !

How do i throw BPEL exception from java embedded activity

Hello everybody,
i want to use some embedded java code in my BPEL process (bpelx:exec). This code would sometimes throw exceptions. How can i deal with these exceptions to control my BPEL process? I would like, in a sense, to do some catching of java exceptions but at the BPEL level... for example, my java code would throw an exception, that my BPEL process would "catch" and react the way i want. Is it possible to do that?
Thanks for your help!

How to detect JBO Exception from within Apps Module Custom Method ?

Hi all,
I have a custom method in apps module (AM) to set "Status" attribute to "A' in an antity, this is for approval.
Also there is a rule that the transaction cannot be approved if it is already cancelled by another user (in multi user environment).
The problem is :
If the AM custom method fail (because it throws JBOException in the entity setter method), How can I know that it fails ?
and report it back to the backing beans that call the custom method ?
Thank you for your help,
xtanto
Below is the code :
1. create a custom method in AM to do : setStatus ("A") ;
public void approve(){
ViewObject bphVo = findViewObject("BpHView1");
BpHViewRowImpl vBphViewRow = (BpHViewRowImpl)bphVo.getCurrentRow();
vBphViewRow.setStatus("A");
2. Do a validation inside setStatus method of the entity :
public void setStatus(String value) {
if (! getCancel() == true )
setAttributeInternal(STATUS, value);
else
throw new JboException("Error ! transaction already cancelled");
3. On backing beans :
public String approveButton_action() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("approve");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
System.out.println("There is JBO Error !!");
return null;
else{
commitButton_action();
return "back";
}

Try this code:
approveButtonAction() {
String navigationString = null;
try {
Object result = operationBinding.execute();
naviagionString = success;
catch (JboException e) {
navigationString = null;
(DCBindingContainer)bc.cacheException(e);
} finally {
if(navigationString != null)
return commitButtonAction();
else
return navigationString;
}

Hi,
The FM might be calling a dialog or bringing a GUI screen up. This would cause the Webdynpro session to disconnect abruptly.
Any conversion exit, GUI screen,dialog popup, transaction handling..etc would cause the webdynpro to disconnect. So you cannot use all FM's as it is.

Bug in Sun code sample... throwing an exception from a static variable decl

I got this line from a Sun tutorial (on logging):
private static FileHandler fh = new FileHandler("mylog.txt");
Declared in a class as a variable. The compiler (1.4) warns that an IOException must be thrown or caught, and refuses to compile this line. I thought I could program Java (been at it for 4 years) until now, and I realize that I don't know what to do. How do you catch an exception thrown outside of a method? Is this really such a hard case, or am I stupidly missing something obvious?
Everlasting gratitude to the kind person who can solve my quandry.
(Code sample taken from http://java.sun.com/j2se/1.4.1/docs/guide/util/logging/overview.html#2.3)

You can do this:
private static FileHandler fh;
static
   try
      fh = new FileHandler("mylog.txt");
   } catch (IOException e)
      //Handle the exception
}I don't think there's anyway of handling exceptions outside the scope of a function.

Readind Date and Time from a folder.Urgent help please

Folks,
I need some help regd reading of date and time from a folder.
I have a folder which has 5 files.
I need to read these files along with the date and time
The date and time has to be in the format:
mm/dd/yy and the time in 11:55
I am attaching my code below,
The f.lastModified() doesnt display the data in the current format
Can some one please please help me to get the data in the format defined above
private void readFoldert(){
   String folder = "/images/";

Here's how to format a time. I hope you can figure out how to format a date:import java.text.*;
import java.util.*;
public class Test {
    public static void main (String[] parameters) {
        Calendar calendar = new GregorianCalendar ();
        calendar.setTimeInMillis (new java.io.File ("c:\\windows").lastModified ());
        System.out.println (DateFormat.getTimeInstance (DateFormat.MEDIUM).format (calendar.getTime ()));
