Difference Between java.lang.ClassNotFoundException and java.lang.ClassDefNotFound Exception
bye
Ram

ClassNotFound when the actual class requested can't be found
NoClassDefFound when some required/referenced class of the actual class can not be found
EG: if foo.A references foo.B in such a way that foo.B is required when foo.A is loaded (EG, foo.A is a subclass of foo.B) then you'll get NoClassDefFound when you try to load foo.A

Difference between exception aggregation in keyfigure

Hi
what is the difference between exception aggregation in key fig properties in modelling and key fig properties in query

Hi Promod,
Exception aggregation in key fig properties is GLOBAL (it will affects all queries,where ever used these key figures),because ur defining at Info object level.
Key fig properties in query is LOCAL (it will affect only for that particular Query) ,because ur defining at query level.
hope it helps.....

Difference between Exception and Error?

PLz i want this for my interview. PLz describe as much as possible with example.

Valid and nice question
Lets try to understand in Short
Exception and Error are designed to manage unexpected behaviour of an application. If the problem is related to the business logic rule say for an instance If I am having an account in a bank and trying to withdraw more than the balance amount this is a scenario where i m trying to break the business policy of the bank.
This is a kind of situation where exception can be thrown so the program wont exit but the rest of the logic of the withdraw() method wont perform.
Error is something related to the system where we cant programetically manage to avoid that problem like memory problem stack overflow if this is a problem no language help u in managing such a problem so it is an error which cannot be handled

Differences between Exception 20 and 10 in MD04

Hello experts,
Depending on the material, I have two scenarios:
Sometimes MRP says to reschedule the PO (message 10):
And other times MRP says to cancel a PO and create a new one (message 20):
Why does this happen? According to which data does occur one behavior or another?? Is there any value in the material master??
Thanks in advance.
Laura

Hi Laura,
10, 15 and 20 are Rescheduling Exception messages.
10- Rescheduling In
15- Rescheduling out and
20- Cancel Process.
If the PIR meets future date demand ie production order then the status would be 10.
Ex: if the PIR is 100 for 01/07/2014 month, and a Production order for 50 in a same month or with in the rescheduling horizon.
If the production order is meets by a future dated PIR ie planned order then the status would be 15.
Ex: if the Production order is 50 for 10/07/2014 month, and a PIR ie planned order for 100 in a same month or with in the rescheduling horizon.
If the Production order created on 10/07/2014 and the PIR in future or within the rescheduling horizon then Exception message is 15.
if the order date is not within the rescheduling horizon days then the exception msg is 20 (cancel process).
Please check the rescheduling horizon - OMDW
hope your clear Laura,

Is there a difference between ipad demo and normal ipad except the software?

Helli, i want to ask if someone know is there any significant difference between ipad demo version and normal ipad for selling ? Except the software difference and is true that ipad demo can be erased to a normal OS And worked normally after that? Thanks

As far as I know only Apple can potentially change the iOS on a demo model iPad to be the proper version, due to limitations within the demo version you probably won't be able to change/update it yourself.

Difference Between Errors and Exception?

I want to know what is the difference between Error and Exception?

Everything is sadly enough catchable as Throwable but
you should never catch Errors. They are an indication
that something has gone wrong in the JVM and they are
not recoverable.Although it is clear that Sun recommends against catching Errors (".. indicates
serious problems that a reasonable application should not try to catch.. etc.."), sometimes, it makes sense to catch some type of Errors.
There was that Java editor (I forgot the name) which would catch OutOfMemoryErrors when the user would try to open a file that was too large.
So instead of crashing, the application would recover from the Error, and I personnally thought that was an interesting feature. At least, a better alternative than the whole application failing.

Difference between Error and Exception

Can anyone tell me the difference between error and exception
Thanz

Errors and Exceptions, in a Nutshell
Errors and exceptions both inherit from Throwable, but they differ in these ways:
Exceptions
Can be checked or unchecked
Indicate an error caused by the programmer
Should be handled at the application level
Errors
Are always unchecked
Usually indicate a system error or a problem with a low-level resource
Should be handled at the system level, if possible
pretty much exceptions cause abnormal flow of the program, errors stop it, least thats my idea, it can get pretty complicated, below is a really good link for htat, also, Google it.

Difference between ERROR_LOGGING and SAVED EXCEPTION

Hi All,
greetings for the day.
i would like to know the difference between SAVED EXCEPTION and ERROR_LOGGING.
my requirement is like without interrupting the main procedure flow (although we got BAD file during the bulk collection, bulk insert )..?
what should i proceed for this scenario?

As already mentioned one is SQL the other is PL/SQL.
So the first decision to make is whether you need PL/SQL to do what you are doing. Use SQL whenever possible.
If you are using SQL then you can't use SAVE EXCEPTIONS so the choice between that and LOG ERRORS is made for you.
There are some major difference between the two:
1. SAVE EXCEPTIONS will work for all datatypes whereas the use of a log table has restrictions.
2. SAVE EXCEPTIONS will not provide ANY indication (other than the error code) of which column(s) caused the exception. A log table can be used to check for problems in a user-specified list of columns
3. SAVE EXCEPTIONS will not providing the offending value whereas a log table will log the offending value so you can examine it.
4. SAVE EXCEPTIONS will not save any of the offending data you must save it yourself if you want it. The log table will save all of the offending data but you must then manage/delete it yourself.
5. SAVE EXCEPTIONS will trap ALL errors whereas dml logging will not.
See 'Error Logging Restrictions and Caveats' in the DBA guide
http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables004.htm
>
Some errors are not logged, and cause the DML operation to terminate and roll back. For a list of these errors and for other DML logging restrictions, see the discussion of the error_logging_clause in the INSERT section of Oracle Database SQL Language Reference.
>
And see Restrictions on DML Error Logging in the SQL doc
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_9014.htm#SQLRF01604
One use of logging tables is in ETL and data cleansing processes. For example incoming data might be 'dirty': values out of range (i.e. CHECK contraint violations), null data when it must be NOT NULL and the like. If a log table is used this data can be filtered out and saved in the log table where it can be examined and/or fixed.
If I have 5 columns that might be 'dirty' an error in ANY of the five can cause all five values to be recorded in the log table. Only one of the values actually CAUSED the error (the exception is raised as soon as there is an error) but the other four values will be recorded. Then when I examine the log table I check all five values to determine which ones are 'dirty'. I can then take appropriate action.
If I were using SAVE EXCEPTIONS I would need to have code that identifies and saves the original source data so I can examine it later.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload

              filename                = filename

         changing
              data_tab                = iflatf
         exceptions

              file_read_error         = 2

What is difference between Iterator and Collection Wrapper?

Hi all,
I dont understand the actual difference between Iterator and Collection Wrapper. I observed both are used for the same purpose. Could any one please let me know when to use Collection Wrapper and when to use Iterator??
Thanks,
Chinnu.

L_Kiryl is right.
Collections support global iteration (through collection->get_next( )) and local iteration (through iterator->get_next( )).
Each collection has a focus object. Initially, the first object has the focus.
Any global iteration moves the focus, which is published by the event FOCUS_CHANGED of the collection.
If you want to iterate on the collection without moving the focus (and without triggering timeconsuming follow-up processes) you can use local iteration. To do so, request an iterator object from the collection and use this to iterate.
And one more advantage of using iterator: it takes care of deleted entities. If you use global iteration then when you reach deleted entity it will be an exception. But there is no exception with iterator in the same situation.

What is difference between Shared ,Exclusive and Exclusive but not commulat

what is difference between Shared ,Exclusive and Exclusive but not commulative lock modes plese tell me

Lock objects are used to synchronize access to the same data by more than one program.
The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table.
There are three types of lock modes
1.Exclusive
2.Shared
3.Exclusive not cummulative
Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
please go through these links:

http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eed9446011d189700000e8322d00/frameset.htm
briefly :
You can lock the table or record by using following types of locking:
1) Exclusive (E) the locked data can only be displayed or modified by single user i.e the owner of the object. Access to other users is denied.
2) Shared (S) several users can access the same record simultaneously, but only in display mode and except the first one, who has asked for the data in update mode.
3) Exclusive not cumulating (X) it is similar to exclusive lock. It allows only a single user access. E can be called several times from the same transaction. In contrast, a lock type X can be called only once during the transaction. Any other call for this lock is rejected.
Activation of Lock Object
1) When you activate the lock object, the functions are automatically generated. And these are ENQUEUE-EZN and DEQUEUE-EZN. EZN is name of the lock object.
2) While ENQUEUE is used in program to set the code over the selected data depending upon the lock object arguments. DEQUEUE is used to release the lock.

What is the difference between PUSH and FETCH

I am a little confused. I use my iphone for both my personal POP email accounts and my business exchange account. I am trying to save as much battery as I can so I turned off push and set everything to manual...but now when I try and get may mail....it either says "connecting" or "checking for new mail" at the bottom of the screen and nothing happens from there.
What is the best way to setup this situation for the most battery life? I don't need it to automatically download emails just when I open the email accout would be nice.
I also noticed that when I delete an email from my iphone on my exchange account, it also deletes is on my desktop at work...I need to turn this off...is it possible?

Hi maxum25,
The difference between push and fetch is that:
When using push, the server sends a signal to the iphone and lets it know that an email is coming its direction. Kind of like receiving a call. The iphone does not need to do anything except receive the email.
When using fetch, the iphone has to wake up every so often and send a request to the server to see if there is any new email waiting for it on the server to download. This takes more time because the iphone sends a request, the server says yes there is some, the iphone says ok give me the new email.
Now the exchange email uses active sync to keep all changes on the exchange server and mobile device in sync. This is automatic and is the nature of exchange and active sync. In order to keep this from happening you would need to talk to your IT dept. and see if they have an imap or pop alternative. Even using imap reflects the changes back to the server.
Hope this helps.

What is the difference between variable and Define

WHAT IS THE DIFFERENCE BETWEEN
these different declarations when it is done using the keyword "variable" and "define"
and both of these are done OUTSIDE "DECLARE"
VARIABLE g_monthly_sal NUMBER
DEFINE p_annual_sal =5000
-- I understand that p_annual_sal will be taken as a CHAR.
-- ALSO IF DEFINE variable acts as macro variable, SO is it necessary to give it some value whenever we define it.
if not what value would be substituted for it?
OR does that mean whenever we want to specify data type for a bind varible we should use VARIABLE and
when we do not want to specify type we use DEFINE?
THANK YOU

Edited by: user6287828 on Feb 24, 2009 11:04 AM

Both are SQL*plus commands. In a real programming environment you will not use such constructs (except a few rare scripting cases).
The difference is how the construct is later used. DEFINE is more like a copy&paste string. Whereever the name of this substitution variable is found it will be pasted into the sql*plus session.
VARIABLE creates a real variable. You can change the value and if follwos the usual principles of variables (including binding).
Example can be found the docs:
from the docs
Where and How to Use Substitution Variables
You can use substitution variables anywhere in SQL and SQL*Plus commands, except as the first word entered. When SQL*Plus encounters an undefined substitution variable in a command, SQL*Plus prompts you for the value.
You can enter any string at the prompt, even one containing blanks and punctuation. If the SQL command containing the reference should have quote marks around the variable and you do not include them there, the user must include the quotes when prompted.
SQL*Plus reads your response from the keyboard, even if you have redirected terminal input or output to a file. If a terminal is not available (if, for example, you run the script in batch mode), SQL*Plus uses the redirected file.
After you enter a value at the prompt, SQL*Plus lists the line containing the substitution variable twice: once before substituting the value you enter and once after substitution. You can suppress this listing by setting the SET command variable VERIFY to OFF.
Using Bind Variables
Bind variables are variables you create in SQL*Plus and then reference in PL/SQL or SQL. If you create a bind variable in SQL*Plus, you can use the variable as you would a declared variable in your PL/SQL subprogram and then access the variable from SQL*Plus. You can use bind variables for such things as storing return codes or debugging your PL/SQL subprograms.
Because bind variables are recognized by SQL*Plus, you can display their values in SQL*Plus or reference them in PL/SQL subprograms that you run in SQL*Plus.
Creating Bind Variables
You create bind variables in SQL*Plus with the VARIABLE command. For example
VARIABLE ret_val NUMBER
This command creates a bind variable named ret_val with a datatype of NUMBER. See the VARIABLE command for more information. (To list all bind variables created in a session, type VARIABLE without any arguments.)
Referencing Bind Variables
You reference bind variables in PL/SQL by typing a colon (:) followed immediately by the name of the variable. For example
:ret_val := 1;
To change this bind variable in SQL*Plus, you must enter a PL/SQL block. For example:
BEGIN
:ret_val:=4;
END;

What's the difference between a web site and a web application?

I'm stumped trying to come up to a difference between a web site and a web application for myself. As I see it, a web site points to a specific page and a web application is more of some sort of 'portal' to content and information.
But where I'm stuck is that a web application is still viewed through a browser (is it not?) and a web site can still view content dynamically, making the line between web site and application prety gray.
For instance, does a web site using ASP.NET or AJAX (I assume ASP.NET is AJAX's proprietary sibling, if not, ignore ASP.NET AND concentrate on the AJAX), becomes a web application because it can retrieve data dynamically and asynchronously or would a website
using PHP and a CMS be more of a web application because it forms the pages on request, based on the request of the client and its content in its databse?
Or maybe I'm totally wrong here - what differenciates between a web application and a website?

This is totally personal and subjective, but I'd say that a website is defined by its content, while a webapplication is
defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that's dealt out to all visitors, while a web application depends on interaction and requires programmatic user input and data processing.
For example, a news site would be a "website", but a spreadsheet or a collaborative calendar would be web "applications". The news site shows essentially the same information to all visitors, while the calendar processes individual data.
Practically, most websites with quickly changing content will also rely on a sophisticated programmatic (and/or database) backend, but at least in principle they're only defined by their output. The web application on the other hand is essentially a program that
runs remotely, and it depends fundamentally on a processing and a data storage backend.

There is no real "difference". Web site is a more anachronistic term that exists from the early days of
the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites).
Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.
If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels
more like an application as a web app.
The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com
as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.
Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some
http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.
