Where's the Exception???

Try creating a JSP containing nothing but this:
<%
String bad = null;
bad.equals("death");
%>
This will show a 404 error and NOT display a stack trace! What gives? When
I have a real problem, how I am I supposed to debug it if
handlePageException eats the exceptions without giving me a stack trace or
even a Exception name?
Try the same code under tomcat and it prints the exception. If I wanted to
put a error page in I believe it would display the page, but I don't care
about that right now. For now I'm just trying to get my stack trace so I
can debug the application.
Any help is greatly appreciated.

And you think this is bad.... Try using entity EJBs and throw an exception
in ejbStore. In the 'standard' SP2, the client (typically a servlet) will
never be notified.

Where is the exception stacktrace - weblogic.webservice.core.handler.Invoke

Hi, I am debugging a Web Service. It sometimes throws an exception while deserializing the input. But when I look through the log all I see is:
####<Jul 27, 2010 9:20:43 AM EDT> <Info> <WebService> <myhost.net> <prodServer114> <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1280236843573> <BEA-220024> <Handler weblogic.webservice.core.handler.InvokeHandler threw an exception from its handleRequest method. The exception was:
java.lang.NumberFormatException: For input string: "".>
How do I make weblogic spit out the exception stacktrace?
I am using Weblogic 9.2.
Thanks in advance!

Where is the cookie exception list in Firefox 17.0.1

i'm looking for the cookie exception list that seems to have moved in later versions. I'm having trouble with Facebook and yahoo mail in that Firefox is showing those sites in frames. If I reset Firefox it works fine, but I am tiring of resetting it twice a day to read my email. It was suggested to add these sites to the cookies exception list - except that it's not where it used to be.

Hi,
You can try setting '''Firefox will:''' to '''Use custom settings for history''' in '''Tools''' ('''Alt''' + '''T''') > '''Options''' > [https://support.mozilla.org/en-US/kb/Options%20window%20-%20Privacy%20panel?as=u Privacy] to reveal the '''Exceptions''' button.

Is there any exception used any where in the block

Hi All,
Is there is any Exception that can be used inside any where in the pl/sql block.
Thanks & Regards
Srikkanth.M

Yes, Srikanth.. many kind of exceptions are there which can be raised within a pl/sql block, after a begin keyword..
for example: if you have wrote select query, it can raise no data found exception (if select query doesn't return anything), multiple rows fond exception ( if query selects multiple rows) other select query related exceptions like table or column not found..
Exception List is here:

How do I delete a Security Exception from the list of items where 'Confirm Security Exception' has been selected?

I looked at all the previous solutions, some of which were the same., but they didn't answer my question.
Firefox 17.01
Ubuntu 12.04
If I go to
Edit --> Preferences --> Advanced --> Encryption
it looks like 'View Certificates' is the likeliest place to look for the Security Exceptions resulting from me clicking 'Confirm Security Exception'.
I have looked at the five tabs on the next dialog box 'Certificate Manager', and the most likely looks like the 'Servers' tab.
On this tab, I can see that there is a button to 'Add Exception...', but nowhere to 'Show Exceptions', and the 'Add Exception...' button only provides means to add a new exception.

Correct: you can find the exceptions under the '''Servers''' tab. Unlike other entries, your custom exceptions should have the '''Server''' column filled out; this should make them easier to locate. Select an entry, then click the '''Delete...''' button.

How to log the exception using Log action in Oracle Service Bus

Hi,
Whenever an exception is raised how to log the exception using Log action in oracle service bus.After logging where I have to find the logged message.

It would be in the log file for the managed server which ran the request. If you are logging the message at a lower level than your app server, however, you won't see it. You should be logging the exception at Error level.

How to get rid of the Exceptions

When I tried to open the client i.e User interface which is MainMenuApp received NO_PERMISSION CORBA exception while attempting to get an initial reference to the mvcf_ControllerFactory from the FactoryFinder. Software defect that should be addressed is that the UI did not recover after catching the exception and required a restart of the UI to connect.
The problem is that cleanWorkspace() in CorbaAdapter doesn't have any failover logic in it at all. The adapter is assumed to be good and if it is not cleanWorkspace() attempts to use a factory that doesn't exist. This throws an uncaught NullPointerException that blows out to MainMenuApp where it is interpreted as a fatal exception and prevents the main menu from starting. So please help me in writing the failover logic in CorbaAdapter
The code for cleanWorkspace is
* Cleans up the entire logical positions workspace.
* @throws AdapterException UserError or Error occured
public synchronized void cleanWorkspace() throws AdapterException
cut_ContextInitData cid = getContextInitData();
cid.clientId = "*";
MVC2CleanWorkspaceCmd cmd = new MVC2CleanWorkspaceCmd(cid);
execute(cmd);
I am giving the whole logic of Corba Adapter. This might help:

Is there a report to track the exception messages after a MRP run ?

We have a scenario at our client site where MRP run is not optimized to the fullest.
The planners are not trained on how to interpret those exception messages.
They are not trained on how to reschedule / expedite planned orders resulting from an MRP run.
Is there a report out in SAP that keeps track of
1) History of number of exception messages by type ( Expedite/Reschedule/Cancel)
2) History of number of exception messages that were acted on or ignored by the planner.
This is to create metrics on the usage of MRP exception reports by planners.
Appreciate your inputs..

The exception messages are dynamic and time dependant. You cannot have history of exception message.. If your user is feeling difficult to use standard MRP reports. Create a new report using a function module MD_STOCK_REQUIREMENTS_LIST_API
It gives all MRP data including exception messages.

Where is the parameter panel on the embedded Crystal Report preview in Visu

Where is the parameter panel on the embedded Crystal Report preview in Visual Studio?
I found a tweet on google about this.. but the link is invalid.. and I could not find the article on SDN.
KB #1486469 - Where is the parameter panel on the embedded Crystal Report preview in Visual Studio? http://tinyurl.com/22thlcg
How do I the show parameter dialog in either WPF or Winforms viewer of Visual Studio 2010.
Parameters are not even visible in the Parameters Side panel. It is empty too..
I see two classes ParameterPrompting and ParameterPrompt both, on initialization throws exception.. even to manually invoke them...
Is it permanently removed?

Hello,
Seems like a reported Bug.
Please check:

How to handle the Exception when RegisterEventProcessorAsync

In our Cloud Service project, we have 2 instances for work role (deploy to Azure), the work role is consume events from the EventHub using EventProcessorHost).
When we want to register EventProcessor to consume data (see below):
await eventProcessorHost.RegisterEventProcessorAsync<eventProcessor>();
Sometimes we will got the Exception:
Microsoft.WindowsAzure.Storage.StorageException: The remote server returned an error: (412) There is
currently a lease on the blob and no lease ID was specified in the request.. ---> System.Net.WebException: The remote server returned an error: (412)

If we got the Exception, we won’t got messages any more.
From the Call Stack, we found it was cause by delete the Blob. So we wonder that, when we call
RegisterEventProcessorAsync,
the hub will delete the blob and renew one in Storage?
If we delete the blob for the EventHub manually and then run our server again. It worked as usual.
But we can do it like this way manually, so is there any way to handle the exception in code to make the EventProcessorHost worked?
Thanks so much!

If we use different blob container name for different EventProcessorHost, is it a workaround for the issue?
 var
eventProcessorHost = new
EventProcessorHost(
 hostName,
 hubName,
 consumerGroupName,
 serviceBusConnectionString,
 storageConnectionString,
leaseContainerName);

Where is the software for the Lenovo G550???

I want to do a clean install and replace the pre-installed Vista with Windows 7.
I see that the Lenovo G550 download page has drivers for Windows 7, but where is the pre-installed software, like Veriface, camera software, and all other pre-installed Lenovo software? I looked at all OS options for the G550 on the download page, and NONE of them had the G550 laptop software, all they had for each OS option was only the drivers.
I understand that I can make a recovery DVD, but as I understand it, it will return the system to the factory fresh state (all pre-installed programs installed, but also with the factory installed VISTA - yuck!). I didn't see any option to only re-install the Lenovo software without also re-installing the OS.
When I look at the download pages for other Lenovo laptops, I see that they have drivers AND SOFTWARE, but the G550 has no software except for the drivers. Since the G550 came with no software disks, and there doesn't seem to be any of the software online, how exactly does one do a clean installation of an operating system, and then re-install the Lenovo software, on a G550?
I was able to find downloads of programs like Veriface on the Lenovo site for different laptop models, but unfortunately those were much older software versions, and for a different Operating system.
Why can't Lenovo post all of the software online? If they aren't going to provide the software on DVD when they ship the PC, then they should at least have it online; so that people can do a reinstallation if necessary. DELL doesn't seem to have a problem putting all of the software for their PCs online, and they also provide it on disk with the PC.
Do I have to find the hidden backup partition and then copy the Lenovo software installation files to a DVD or different drive myself? Has anyone done this, and if so, can they please provide some assistance as to the best way to accomplish this task?
If there is a different/easier way to accomplish my end goal of a G550 with a Windows 7 clean install, and also with a re-installation of all pre-installed Lenovo software, I would be extremely grateful for any assistance. If there is also a way for me to select which factory software I wanted to install, that would be even better ( I don't need all of the crapware that came on the PC)
Thanks in advance,
Sven

Thanks, I'll give that a try when I finally get the Windows 7 upgrade disk.
It seems ridiculous that Lenovo doesn't support this product for Windows 7, especially when they mentioned the "FREE" upgrade (with ridiculous "shipping and handling charge") to Windows 7 on the web page where I ordered it. Being a reasonable person, I assumed that when they offered a "Free" upgrade to Windows 7 with the PC, they would also provide the basic software to allow the built-in hardware like webcams to keep on functioning as they did under Vista.
Had I known that they would refuse to offer any software on disks or download, I would have ordered a DELL or some other PC that has a reasonable level of customer service. I am not a typical user; I don't call in for customer support. All I need is the software and drivers, and I will install it myself.

The exception Privileged instruction.

Hello,
I builded a dll which communicates with TDC card. But when I call dll from labview. It gives me the error
The exception Privileged instruction.
(0xc0000096) occured in the application at location 0x02e6121c.
I have installed giveio driver.
I am not getting where am I geeting wrong. Can somebody help me out.
Regards,
Maithili

Maithili,
It very much sounds like the error is in the DLL that you built. I assume that you have tested it outside of LabVIEW?
Do you know exactly where the error is happening? You should set a breakpoint on the Call Library Function node and if the error happens before then, then the error is in LabVIEW. If the error happens during the Call Library Function, then the error is in the DLL itself. From there, you can print information from your DLL as you go to see where the crash is happening or use the information in the "Using External Code in LabVIEW" manual that is on your PC in the manuals directory under your LabVIEW directory.
With no files (and no hardware to test if I had), I cannot offer any more advice. If you can do a little more digging or post a
more detailed explaination of your issue, then the community can take another look.

Where did the analogue in feature go?

Where did the analogue in feature go?
None of the HD cameras I have searched for have a analogue input. In fact, I have found only one MD camera that has that capability.
http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=1055 1&storeId=10151&langId=-1&productId=11038809

Hello! I said... I want the ability to input analogue video into my camcorder so I can continue to transfer VHS and input and record video from other sources. The new HD cameras on the market will not allow you to record video from any source except for the lens.
I have HD cable box. I want to record my HD programs from cable (HBO, Starz, etc) to my camera, download the video to my Mac from the camera and then edit them in iMovie and create professional looking movie DVD's in iMovie.
iMovie HD can work with mini DV HD cameras and HD video. I was not aware of a system requirement for working with HD content.

How to write the exceptions in function module

dear all,
how to write the exceptions in function modules with example.
thanq
jyothi

Hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
· The RAISEstatement terminates the program and switches to debugging mode.
· The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION read_spfli_into_table.
""Local Interface:
*" IMPORTING
*" VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*" EXPORTING
*" VALUE(ITAB) TYPE SPFLI_TAB
*" EXCEPTIONS
*" NOT_FOUND
SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
IF sy-subrc NE 0.
MESSAGE e007(at) RAISING not_found.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
wa LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
EXPORTING
id = carrier
IMPORTING
itab = jtab
EXCEPTIONS
not_found = 1
OTHERS = 2.
CASE sy-subrc.
WHEN 1.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Or
just have to decide what exceptions u want and under what conditions.
then declarethese exeptions under the exceptions tab.
in the source code of ur function module.
if
like this u can code .
now when u call the function module in tme mainprogram.
if some error occurs and u have declared a exception for this then it will set sy-subrc = value u give inthe call of this fm.
in the fm u can program these sy-subrc values and trigger the code for ur exception.
Please reward if useful
Regards,
Ravi

Unable to resolve the exception READ_REPORT_LINE_TOO_LONG in Abap program.

Hi,
I am getting the exception READ_REPORT_LINE_TOO_LONG in my abap program.Given below is the full analysis of the exception and then the program code :-
Error Analysis :-
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_READ_SRC_LINE_TOO_LONG', was
not caught in
procedure "K_KKB_FIELDCAT_MERGE" "(FUNCTION)", nor was it propagated by a
RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
There was an attempt to read program "ZANI_TEST_INTERACTIVE_ALV" from the
database.
The READ REPORT statement allows you to copy a program text into an
internal table. The occupied line length in the program text must not
exceed the width of the internal table.
The internal table "\FUNCTION=K_KKB_FIELDCAT_MERGE\DATA=L_ABAP_SOURCE[]" is 72
characters wide. The program line is

hi,
it is getting because of fieldcat hear ur internal table is having all fields in lfa1, lfa1 is having more fileds alv cont display that much fields at a time . for that u are getting that messgae . u can solve this problem by filling fieldcat table manuvally insted of by FM 'fieldcat_merge'. fill filedcat table some fields which are need to display by manuvally.
thanq,
