Why should we use WSDL for developing webservices

I need to develop Webservice Application for our Client .
I dont know anything about WSDL4J
Hi from the net i found this
"The Web Services Description Language for Java Toolkit (WSDL4J) allows the creation, representation, and manipulation of WSDL documents.
Is the reference implementation for JSR110 'JWSDL' (jcp.org)."
But anybody please tell me why should we use WSDL for developing webservices ??
Is there any specific advantage we will get ??
And Can body please point me a link where to start for working with WSDL4j ?
Thank you very much

i seriously doubt you want to use wsdl4j unless you are doing really advanced webservice work. assuming you are developing this webservice from scratch, you basically want to use JAXWS: define an appropriate interface and your value classes, and let JAXWS do the rest. metro is the JAXWS implementation included in the oracle jdk and it has great tutorials and reference documentation online. i'd suggest you start here: http://metro.java.net/getting-started/

Why should we use BRTOOLS for oracle data backup?

Hi there,
Any one of you have any idea on specific advantages with using BRTOOLS for backup over using only Oracle RMAN?
Are there any advantages using brbackup in databackups which we do not get with RMAN alone?
thanks

Why should I use BO BI 4.0 for my existing SAP NetWeaver ?

Dear Sirs,
Question about BusinessObjects BI 4.0 & SAP Netweaver 7.0.
In my company we use NetWeaver for a year. We have some reports on portal, so we have some analysis via www. It seemed to me that this is enough for us.
Now on the market is available new version of BusinessObjects - version 4.0.
My question is :
Why should I use BO BI 4.0 for my SAP BW?
What will I gain by implementing BO BI 4.0 in conjunction with SAP BW?
Can I use existing reports on the new platform?
Can you give some links to documents, presentations and notes to answer these questions?
Best regards,
Emmo

Hi Emmo2000,
Please see my answers below:
Why should I use BO BI 4.0 for my SAP BW?
What will I gain by implementing BO BI 4.0 in conjunction with SAP BW?
Please see this SDN article which covers a lot of the new features of BI4.0 :
/people/ingo.hilgefort/blog/2011/03/24/sap-integration-update-9--should-you-start-with-sap-businessobjects-40-or-wait-for-41
Can I use existing reports on the new platform?
There is the ability to integrate BexWeb applications via our BI Launchpad. I'm not sure if this is what you are referring to but the following should clarify:
http://wiki.sdn.sap.com/wiki/display/BOBJ/HowtointegrateBExWebApplicationsintoBI4.x
Can you give some links to documents, presentations and notes to answer these questions?
For detailed information on the BI4.0 suite, I would direct you towards our product documentation:

I hope this is helpful and fully answers your question.
Kind regards,

CCMS is used for system monitoring , why should we use solution manage ?

CCMS is used for system monitoring , why should we use solution manage ?
Whats the relationship between CCMS system and SolMan?
Thank you .

hi,
I just want to ask a question. At our client we have solution manager and CCMS. There is data in CCMS I can extract, it is loading on BW side ok the same number of recs, but the problem on CCMS cubes says there are the same number of record in the cube and also showing as the data is ready for the reporting. But when I run the report and view the data as listcube it is empty.
ANy of you have the situation like this cube say it has the data but when do th BEX or infocube contents the cube is empty nothing in there. The same thing is happening with hourly, 15 minute and daily cubes.
Anyhelp on this matter is appreciated

Why should I use EJB

Hi,
My name is Gandharv Sirohi. I am a student, and new to EJB. I want to know why should I use EJB, before I can start learning it if every thing can be done using Java Servlets and JSP.
I tried to find out the answer to this question in books but there is no satisfactory answer.
Can some body help me understand this simple question. I will be thankfull

Hi gandharv,
It's true there are a lot of services available to both the web tier and the EJB tier. One of the
real strengths of EJB is support for transactional business logic. Web components can
explicitly demarcate transactions via UserTransaction, but container-managed transaction
support in EJB components at the business method level offers a much simpler approach
for developing and maintaining such applications. An example of some EJB services not available
in the web tier are : method-level security, RMI-IIOP access, message-driven beans,
transactional/persistent timer service, stateful components, extended container-managed
persistence contexts, guaranteed single-threaded execution, and interceptors.
Of course there are many services available to the web tier that are not in EJB. It's not
about picking one of the two that should always be used. Like any tool/technology, each has its strengths, weaknesses, and design center.

64 bits: why should I use it?

Just for the sake of discussion: If I have a program offered in 32 and 64 bit modes, why should I use the 64 bit version?
For example, the well known Videolan Player, aka VLC Media Player, recently updated to version 1.0.2, comes in 32 an 64 bit flavors. When would one version be used in lieu of the other?
And saying "because it is bigger and hence better" is not true. Even Apple points out in the developer pages about the 64-bit fallacy: in that mode, all data structures duplicate in size and if the hardware remains the same, performance will suffer cause you have to push twice the amount of information.

I just did a test with VLC Player (version 1.0.2), I played the same video in both 32 bit and 64 bit modes (NOTE: NOT talking about the kernel, but the program). Played it several times in both modes and even alternated between modes. In 64 bit mode it caused one of my processors to spike to 104% usage for the first 20 sec before dropping to 4-5%. In 32 bit mode processor usage remained at 4-5% the entire time.
Played the same video in Quicktime Player X in both modes and saw no difference (used 5-8% processor usage).
So to answer the question about when to use one version over the other I would say if one version causes notable problems/issues and the other doesn't than use the one that doesn't. Generally you shouldn't see a noticeable difference except in high-end programs that are crunching massive amounts of data.

Why should we use DSO instad of Infocube i BW7.4-SAP BW7.4

Dear All,
now I'm working with HCM- Payroll (BWreports) Standard reports, data flow is datasource--->Infocube--->Reports, but my architecture given data flow datasource--->DSO--->Multiprovider-->Reports, this is in SAP BW7.4, could any one explain me why should we use DSO instead of infocube..
Thanks for your helping...
Regards,
Narasimha

Hi
In Loading purpose:
Better to use DSO, becouse it involves 3 tables ie New data table, Active data table and Change log table.
in case of INFO CUBE, here it involves more than 3 tables ie by default 3 dimension tables are existedby SAP... at least we will create 2 tables ie 1 dimension table and 1 fact table ....here it involves 5 tables.( 3 default+1 dimension+1 Fact table)
Conclusion: When we create INFO CUBE it will takes more time compared to DSO because it involves 3 table
Conclusion: Best practice is when we load data to taget, better to use DSO
In Reporting:
Cube will give summerised data whyle reporting and it is multi dimensional,ie we can analyse the data in multiple ways.
DSO will give detailed data whyle reporting and it is 2 dimensional , ie we can analyse the data in 2 dimensional way only
Conclusion: Best practise is Whyle reporting better to use INFO CUBE

Why should I use SQLJ

Why should I use SQLJ instead of JDBC, is it for faster Acess than JDBC, or for any other reasons

Why should I use SQLJ instead of JDBC, is it for
faster Acess than JDBC, or for any other reasonsJust guessing...
It should be faster - but you should test.
I would suspect that it is going to be harder to maintain because it is less used (thus less tested), less known (so harder to hire people to maintain) and less 'standard' (thus figuring out what went wrong can be harder.)

Why should I use xinetd?

Im using inetd, but in mandrake I had xinetd, and somewhere I had read that it is better. Is this true?, and if so, ahow do I install it, cause it's not in pacman (i know I cant install it from source, but I wonder if it's hidden somewhere in the distro)

http://www.xinetd.org/faq.html
Q. What is xinetd ?
A. xinetd is a replacement for inetd, the internet services daemon.
Q: I am not a system administrator; what do I care about an inetd replacement ?
A: xinetd is not just an inetd replacement. Anybody can use it to start servers that don't require privileged ports because xinetd does not require that the services in its configuration file be listed in /etc/services.
Q. Is it compatible with inetd ?
A. No, its configuration file has a different format than inetd's one and it understands different signals. However the signal-to-action assignment can be changed and a program has been included to convert inetd.conf to xinetd.conf.
Q. Why should I use it ?
A. Because it is a lot better (IMHO) than inetd. Here are the reasons:
1) It can do access control on all services based on:
a. address of remote host
b. time of access
c. name of remote host
d. domain name of remote host
2) Access control works on all services, whether multi-threaded or single-threaded and for both the TCP and UDP protocols. All UDP packets can be checked as well as all TCP connections.
3) It provides hard reconfiguration:
a. kills servers for services that are no longer in the configuration file
b. kills servers that no longer meet the access control criteria
4) It can prevent denial-of-access attacks by
a. placing limits on the number of servers for each service (avoids process table overflows)
b. placing an upper bound on the number of processes it will fork
c. placing limits on the size of log files it creates
d. placing limits on the number of connection a single host can initiate
e. place limits on the rate of incoming connections
f. discontinue services if the load exceeds specified limit
5) Extensive logging abilities:
a. for every server started it can log:
i) the time when the server was started
ii) the remote host address
iii) who was the remote user (if the other end runs a RFC-931/RFC-1413 server)
iv) how long the server was running
(i, ii and iii can be logged for failed attempts too).
b. for some services, if the access control fails, it can log information about the attempted access (for example, it can log the user name and command for the rsh service)
6) No limit on number of server arguments
7) You can bind specifc services to specific IP's on your host machine

Why should i use Apple 'Mail' if i use others like G-Mail?

Simply: Can or should i just remove 'A-Mail' so it's icon stops jumping & bothering me to sign up?
•THANK YOU, and gratitude to whoever can help me unerstan.
*I'm 67 and not up to speed on such things.
BACKGROUND, if necessary:
•For years I've used only the Mail service of my ISP, Dslextreme ('DSLX').
I've never used Apple 'Mail' , & never set it up to service mail from any of the mail services that i do use.
I never activated 'A-Mail' and i don't think there is mail in it. Nor have i deactivated 'A-Mail', and it's still on my screen in the 'Dock'.
•But from time to time, and inexplicably to me, the 'A-Mail' icon seems prompted to start 'jumping' and wanting me to use it somehow, like sign up for it. This was a minor annoyance so i just clicked to close it and so ignored it and moved on.
This seems to happen when a website i'm on wants me to e-mail them and on their page i seem only have a choice to use 'A-Mail', none other, so i am pre-cluded from communication.
•Just recently DSLextreme switched all us users over to G-Mail.   They turned over their mail operation to GMail and urged us to also getting a G-Account, which i have finally done.
•I know that A-Mail 'works with the most popular email systems' like G-Mail.
•"A-Mail" = Apple's 'MAIL'.   To avoid confusion caused by the generic word 'Mail', I'm going to call Apple's 'Mail' "A-Mail".
I've spent over an hour trying to make my problem clear to you.    I hope i have succeeded.

Apple mail is simply the default email application in OS X. It is not an email service/email address.
Using an email application, you can read all your email in the same place and store them on your local drive.
To answer your question, "Why should i use Apple 'Mail' if i use others like G-Mail?"
You use a mail application for the same reason you use the internet when you could simply drive to the store to buy things or go get a newspaper or go to the library or go to the movie theater, etc.
But from time to time, and inexplicably to me, the 'A-Mail' icon seems prompted to start 'jumping' and wanting me to use it somehow, like sign up for it. This was a minor annoyance so i just clicked to close it and so ignored it and moved on.
This seems to happen when a website i'm on wants me to e-mail them and on their page i seem only have a choice to use 'A-Mail', none other, so i am pre-cluded from communication
because the website is attempting to open your email application.
Sounds like you simply use a web browser to view all your email.
If you want to send an email from a web page, you need to copy an email address, open your email account in your web browser, create a new email and paste the address.

How to use indesign for developing a magazine

Hi Friends,
i am using Indesign for the past 2 1/2 years. Now i have to use indesign for developing a magazine. But i come across few problems. Pls help me to solve.
1. the page dimension is 210 x 297 mm. i want a bleed area of 5 mm on each side. Then should i have the document size as 215 x 307 mm (for one side). Or is there any way to mark bleed.
2. Is there any scripts, especially to be used in pagination of the magazine.
3. I have placed Auto page number in the master page, but when im placing picture in a page for the full extent, the page number is not visible (as it is in the mater page). Should i manually type the page number there or any other way to do it.
4. Is there any exclusive tutorial to learn to the core about developing a magazine in indesign.
Should i furnish any more details?
Please help me in these problems. Thanks in advance to all.
regards
karthik.r

1. the page dimension is 210 x 297 mm. i want a bleed area of 5 mm on each side. Then should i have the document size as 215 x 307 mm (for one side). Or is there any way to mark bleed.
No you should make your indesign page size the size you want the magazine to be when trimmed. If it's 210 x 297 mm then make the size of your document that size.
When you make a new document you can click the More Options to reveal the bleed setting. Use 5mm for all sides.
Make your document using facing pages, you don't need bleed for the inside edges, as this for the spine. Make sure that all your images, backgrounds etc. go out as far (or beyond) the red line. You don't need to this for things that will not be near the edge of the page.
Set up a "Safe Area" for your images, that will be an area roughly 5 mm from each side where no text or anything will go near the edge of the page. If it goes beyond this area you should consider extending it into the bleed area.
DO NOT PUT TYPE near the edge of the page. Keep it well away, possibly 10 - 15mm.
2. Is there any scripts, especially to be used in pagination of the magazine.
Pagination is usually done by prepress when you send the final pdf. Setup your magazine with the pages flowing in sequential order, e.g., 1 - 100.
Make sure the amount of pages in the magazine is divisible by 4. That is, a 94 page magazine would not do, as that's 23.5. But a 92 page or 96 page would be better because it's dvisible exactly by 4, ideal for printing.
3. I have placed Auto page number in the master page, but when im placing picture in a page for the full extent, the page number is not visible (as it is in the mater page). Should i manually type the page number there or any other way to do it.
If you want page numbers on pages like this, you should think about putting master items on a new layer and sit that layer on top of all the other layers. You should also consider making different pages, based on the current Master Page (making child and parent masters
http://en.allexperts.com/q/Adobe-InDesign-1839/Parent-child-master-pages.htm
http://www.peachpit.com/articles/article.aspx?p=1323251&seqNum=12
http://www.adobepress.com/articles/article.asp?p=1324255
You can google more yourself
But the idea is to make master pages with different coloured folios, like white folios for pages with dark images, as black folios would not show up. But it's up to you. It's best not to manually inser the page numbers.
4. Is there any exclusive tutorial to learn to the core about developing a magazine in indesign.
Three are no hard and fast rules about developing a magazine in InDesign. Follow a logical procession of thought. Start with thumbnails, develop sketches for each content, create content in InDesign, proof it, etc.
There are some pointers here http://www.graphicdesignforum.com/articles/Magazine_layout.htm
You should look into Grids http://www.thegridsystem.org/categories/templates/
http://graphicdesign.about.com/od/layout/a/grid_system.htm
http://desktoppub.about.com/od/grids/Grids_for_Desktop_Publishing.htm
http://desktoppub.about.com/od/designprinciples/l/aa_balance4.htm
The rest is up to you.
Good luck.

Diagnostics: Why should I use it?

Hi everyone,
I got some questions regarding SAP Solution Manager RCA / Diagnostics;
- Why should I use it, what are the benefits and how is this related to (getting) SAP Support.
- Is it a prerequisite? ( for Support or any scenario( EEM, Project, EWA's ) )
- Can I use HP Diagnostics instead? Get I still support?
- Which scenarios can't I use now or in the future ( SolMan 7.1 )?
Thanx
Meindert

Hello Meindert
It's recommended to at least set it up for Java based SAP systems.
It gives more information to find the root cause of crashes, without it, java based SAP systems do not always offers sufficient information or you would have to use other third party tools to analyze the crash situation.
I find it to be very useful, of course you have to know how to use, when to use what and so on but you can find user guides on service marketplace [http://service.sap.com/diagnostics].
It also offers additional tools to be used such as Configuration Validation which can be used to check the configuration of multiple SAP systems against a template (or predefined templates). Configuration validation can be used to check that your landscapes are in sync (kernel, patch levels, parameters and so on). Prerequisite is E2E Change Analysis (which needs to diagnostics agents to work).
I would even recommend to install it for at least each productive SAP system you have (regardless if it's java based or not).
I do know it's a lot of additional work, installation of the agent itself is fast, making sure everything works properly is another story (I schedule a day work to perform installation, configuration and check all functionality for one such agent).
Kind regards
Tom

Why do we use dunning for vendors

Hi All...
We create dunning for customer to send them reminders for payment....But why do we use dunning for vendors (in Vendor Master Data)??
Txk,
Umesh

Hi,
If you dun customers who are also vendors and want to clear the items, the dunning program lists both the overdue customer items and the overdue vendor items in the dunning proposal, and determines a joint balance.When you dun a customer who is also a vendor, only the master record information of the customer is relevant.The items can only be cleared if the same dunning procedure has been defined in the standard dunning area for both customer and vendor.
Hope this helps you. let me know if you need anyother information.

Should I use flex for my website

Hey, I am having trouble figuring out if I should be using
flex for a site similar to the BBC site:
http://www.bbc.co.uk. I have
started the site in flex but I am running into a lot of problems.
It could be that I am a newbie to Flex, but wanted to make sure if
I should still be going a head with this in Flex. Any advice would
be appreciated.
Thank you,

I would say that if you don't know the answer to that
question, then the
answer is probably no. You need to have a pretty firm
understanding of how
sites like that work under the hood before trying to build
one in Flex.

Why should we using ABAP code in RSQ02

Hi dear,
this is only an additional possibility to manipulate your data, but this is not due !
Did you know that Marc Bernard wrote a very useful doc about ABAP and BW ?
