X509Certificate in java and javax - whats the difference?

Hi,
I wonder about the two same named classes X509Certificate in
java.security.cert and javax.security.cert .
Is there any difference?
Olek

The javadocs for javax.security.cert.X509Certificate say that it is deprecated and that you should use java.security.cert.X509Certificate instead.

3000 and 3400 : Whats the difference in performance

my wife (being the wonderful woman she is) has ordered me an Athlon64 3400 for my birthday.
whats the perfomance difference like between the 3000 and the 3400, will i notice a difference at all ??
and does anyone know how well the 3400 overclocks ??

a 3400+ typically is faster than an overclocked 3000+. They both overclock in the same way. However overclocking any of these depends more on other componants and there tolerance to having the system clock changed. SATA drives and AGP cards are especially touchy about changes to the system clock.
Just the same if you can overclock say by 5% to a 3000+ then you should be able to do about the same to a 3400+.

Tints and CYMK - Whats the difference for screen display and print

Hi,
What is the 'technical' difference between a tint and CYMK? For example, if i create a box with a fill of C:0 Y:0 M:0 K:40 is this the same as a black fill with 40% tint?
Knowing that all screens and printers give different results, is the difference even noticeable? What about 'best practice' / 'industry standard'?
Workflow/context- I create artwork (documents with combinations of images, graphics and text) in either Ai or ID which all go to PDF and I present them either on screen or through print (regular printer - none of my printed artwork use printing plates).
Thanks for your advice in advance.

A tint is just a lighter version of your swatch, so yes, 0,0,0,40 CMYK is exactly the same as using the [Black] swatch and setting the tint field in the panel down to 40% or creating a tint swatch with a 40% value.
Not all colors are CMYK. On screen you use RGB and most desktop printers expect RGB data as well. On press you might use spot color inks if you have only one color and tints of that color to add, or you need some color that can't be easily produced in CMYK in a full-color job. You probably shold not be using spot color in your work since you don't go to press and printer simulations of many spot colors are quite bad. You'll find the really saturated colors tend to be out of range for most printers, too, if you use RGB, but if you can accept that your printed output may not match the screen (and unless everything in the workflow is calibrated, including ALL the monitors you might be working with and all the printers you might use for output, output on remote devices probably won't match what you see on your own monitor and printer), I would design for the screen if that's the primary presentation and let those out-of-gamut colors geet clipped in print.
Printing tints is a little trickier than you might think. Dot gain (how ink spreads as it is absorbed into paper) tends to make tints seem a little darker in print.

Tolling, Plant Abroad and Intercompany - Whats the difference

Hi All,
I need to understand the difference between the above 3 concepts from SAp point of view. Can anyone provide a suitable information pls?
rgds..Ameet

Hi,
TOLLING -
This scenario describes the process of toll /subcontracting. In this particular case, we firstly forecasts the future requirements based on past consumption. And we find the stock of similar material in the warehouse but need additional job processing, This job processing is carried out by an external service provider (subcontractor).

7455A and 7455B - Whats the difference?

Hello once again,
Sad news to report that I have the 7455A dual processor 1.25. What am I missing that the 7455B dual 1.25 has? In other words, should I consider going with a 7455B rather than the 7455A?
I am now confused!

Ok, does that make my processor bad? I don't know why I am complaining! I guess its because of the 1.42 dp that I wish I had. Although, once again coming from a digital audio 733 mhz mac to a dual processor machine for the 1st time - I guess I should be grateful and for $430 dollars that I paid for the machine I guess I really got a great deal on it.
So, really there is no speed difference or any other bump up in performance with the G4 7455B versus the 7455A?
I guess call me paranoid , but I keep telling myself that the bump in speed compared to the 1.42 is not worth for me to consider it. Only 10-13 percent which is still not alot.
Oh, I finally found out how to pull the processor card from my computer. I just cleaned off the OLD thermal compound and put fresh brand new compound on it. I seems that my machine is much more stable now at lower temperatures. I will have to wait and see.

Would you please summarize what the difference between tc and alv?

hi, experts,
would you please summarize what the difference between table control and alv base on the function and usage practice.
for example, as i know:
1.edit
tc: can edit in the same screen and save.
alv: pop up a sub screen to let user edit, so this is unconvenient.
2.functional button
alv: can have many functional button as default ,eg. sort, summary and so on
tc: developers must implements by himself.
3.color
alv: can have and change color
tc: cann't changed color
some client may required the data displayed in alv and edit in tc ,such as example BCALV_EDIT_02.
above are my idea, experts, would you give me some comments on my opinion and summarize what the difference between those two components? i should make it clear in order to consult the UI with my client.hunger for your advice, thanks!

ALV Grid is basically used for display puropse. It is more user friendly. There are arious features ( such as coloring, sorting, saving to a local file, sedning by mail etc. ) These featurs make ALV Grid a very good option to display the data .
However , the table control is not only used to display data take from the database table, but also you can do operation such as deletion of data from database table, insertion of data into the database table and updation also. Yeah it has not got the various features whihc ALV has.
So table control and ALV Grid , if you are just using for display purpose, then ALV Grid is a better option due to its layout and attractive features. But if you want to do the database operations other than display, table control can be used.
As far as execution is concerned, I think ALV Grid is faster.
ALV grid control is faster when compared to Table control. But the comaprision is Negligible .
One of the major differences comes in taking of line items - ALV has an advantage over Table Control when it comes to update database from it.Table control only allows maximum of 999 records at a time where as this limitation is not there in ALV.
Also,a main feature of ALV Grid is that it contains a standard set of functions. These functions extend beyond the functions of a table control.
These two UI elements require different keyboard navigation, with ALV Grid being more user-friendly.
An application can display table data in ALV Grid or in a table control. In some applications you can choose between displaying and editing data in either ALV Grid or a table control. If a configurable button () appears in the right upper corner of the table, it is a table control.
Basically ALV is a way to display the output and Table Control is designed in screen painter through which you can get entries in Table Control, can delete some records etc for further processing and its not use only for Display.
ALV is Application List viewer:-
Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
TABLE CONTROL:-
ABAP offers two mechanisms for displaying and using table data in a screen. These mechanisms are table controls and step loops. Table controls and step loops are types of screen tables you can add to a screen in the Screen Painter.

What the difference between getRequestMap() and getRequestParameterMap() ?

ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
Map requestMap = ec.getRequestMap();
Map requestParameterMap = ec.getRequestParameterMap();
What the difference between getRequestMap() and getRequestParameterMap() on earth?
I have read the spec but I did not quite catch it.
Thanks a lot!

With the getRequestMap() you are operating with request "attributes". (with the getRequestParameterMap() with parameters)

O. Portal XML util. Vs. O. Java XMLutil., whats the difference?????

O. Portal XML util. Vs. O. Java XMLutil., whats the difference?????
OK, in the O. Portal doc. there is this link:
http://technet.oracle.com/docs/products/ias/doc_library/1021doc_otn/dev.102/a83730/toc.htm
that talks about
oracle.portal.utils.xml.v1
And then there is the O. Java XML utils. Talked about in:
http://technet.oracle.com/docs/products/ias/doc_library/1021doc_otn/dev.102/a86030/adx17paj.htm#1000433
I guess my questions are:
1) Are there TRULY to different O. XML utils. that do the XSLT transformation, one being oracle.portal.utils.xml.v1, and the other being the O. Java XML utils????
2) When would you want to use the O..Portal XML (oracle.portal.utils.xml.v1,) stuff for XLST???? Is the oracle.portal.utils.xml.v1 stuff just as robust as O. Java XML utils???
3) When would you want to use the O..Java XML ( O. Java XML utils. ) stuff???? For XSLT???
THANKS!!!
null

Both use the same Oracle core XML Developer's Kit components for XML parsing and XSLT transformation.

What the difference and use between   of TABLES and SY-REPID?

Hi,
Experts,
I have came accross 2 cases that i can't able understand
EX1:
TABLES: VBAP   -
>( Here also Appplication Server(AS) creates Wrokarea of Structure VBAP but, by
data: v_vbeln like vbap-vbeln.    double clicking on variable v_vbeln AS taking me to DDIC VBAP table VBELN field then what the using declaring tables. )
( and )
DATA: VBAP TYPE VBAP -->( Here also Appplication Server(AS) creates Wrokarea of Structure VBAP data: v_vbeln like vbap-vbeln.    but,double clicking on variable v_vbeln AS taking me to user declared VBAP
                                              i.e., above DATA declaration statement )
Then Which one is better in Functionality wise as well as Performance wise or when we have to go for TABLES and when we have to go for DATA declaration of DDIC objects.
EX2:
what the difference between
I know that SY_REPID is not a system variable. And also that
Data: vrepid type SY_REPID.--> Predefined data type in ABAP
and
Data: vrepid like SY_REPID.-> Predefined Constatnt in ABAP( it is a constant it allowing with out VALUE
attribute)
what difference between them and when we have to go Data: vrepid type SY_REPID and when we have to go Data: vrepid like SY_REPID.
Thank U,
Shabeer Ahmed.

Hi Ahmed,
TABLES:
VBAP.   " DDIC
DATA:
v_vbeln like vbap-vbeln.
*Here you are using the DDIC VBAP
DATA:
VBAP TYPE VBAP.
DATA:
vbeln like vbap-vbeln.
*Here you are using the local data object as your data type so it will always
* take you to user declared VBAP which is declared by you.
DATA:
T_VBAP TYPE VBAP.
DATA:
vbeln like vbap-vbeln.
* here its using T_VBAP not DDIC VBAP
And for performance always the second option is better, use Data instead of tables, declare your own local structure.
Data:
vrepid type SY_REPID. thereis nop redefined data type in ABAP as SY_REPID
* its SY-REPID which is a system variable.
Data:
vrepid type SY-REPID.
Also refer to the links:
Difference between tables statement and by using type statement
for type and like:

With luck,

Whats the difference between arrayCollection = null and arrayCollection.removeAll()?

Whats the difference between arrayCollection = null and
arrayCollection.removeAll()?

In arrayCollection = null; statement you're setting this
reference to null and potentially making it available for garbage
collection. I say 'this reference' and potentially because, as you
may know, there might be other references to this array collection
object that won't be affected by this statement and hence it won't
be GC'ed.
arrayCollection.removeAll() says that I want to empty this
array collection for all the reference that we pointing to it. That
is, remove all the objects from the collection -- and of course
make them 'potentially' available for the GC -- the size of the
array collection would be reduced down to zero and all the
references would be pointing to a valid but empty collection.
Hope this helps.

Whats the difference between list and lov ?

Whats the difference between list and lov ?
i can do the same things with a list what an lov can do .
infact a list is more better. cause the list doesnt hold/show a range of values, and only has the items value iteself.
while the lov can get all the values of items depending on the query.
like
select ename, job, sal from emp
will show all the three items values in lov?

Also, if you're looking in the US store, the prices are:
- Airport Express (small, no ac) $99 - Has audio out for speaker connection using Airplay. Can share a USB printer only.
- Airport Extreme (larger, ac) $199 - No audio out, can share a USB printer or hard drive.
- Time Capsules (2TB, 3TB at $299, $399) - have ac wireless and a backup hard drive for Time Machine which the other Airports do not have.

What the difference between u0093Valuate GL Account Open Itemsu0094 and u0093Valuate G/

hi gurus
What the difference between Valuate GL Account Open Items and Valuate G/L Account Balances?
We found out that when we perform valuate GL account Open items there will be reversal done at the same time whereas when we perform Valuate G/L Account Balances there is NO reversal posting even though we hv entered the reversal posting date and Period.
Pls advise which one we should perform?

Valuate GL Account Open Items are for open item managed accounts including vendor/customer accounts. The valuation is performed for each (open) line items on key date specified.
"Valuate GL Balance" is for account NOT managed on Open Item basis but managed in foreign currency. The period balance of key date in foreign currency is valuated. Reversal document can be created by selecting 'Reverse postings' in "Postings" tab.
