A BIG AND BAFFLING QUESTION
How do you cast an object to a subclass which is a variable at runtime? The object is a Class object which
may vary in a program. Now how do you cast a superclass object to the class associated with this Class object.
For example, you may cast a Component object to a Container or JComponent depending upon the value of the
Class object.
Thanks in advance.
It's not an interesting question unless you can also answer the question of how you are going to write the piece of code following. Having got a thing which is either a Component or a JComponent, how are you going to write the code that's going to handle it?
... and the answer of course is that you can't. You just have to write two (or N) logic branches, one for each possible case. In the case where you won't even know the class until runtime you can't write the code following at all.
Unless you use Reflection.

Oracle BPM / SOA Suite and Big and Complex Scenarios
Hi people,
I have worked for a company that in the past chose Oracle BPM (ALBPM at the time) and one of the big problems that the company had was in relation about big processes and complex scenarios.
This company is for the e-commerce area and our processes can have many instances at the same time, for example, a process to all the "order flow" can have thousands, maybe millions instances at the same time.
So we choose to abort the BPMS option in the past and now we back to talk again about BPMS and one question is always made by the company board: if we use BPM again, the new versions can be support all the our volume data?
To be honestly, I don't have this answer so I like to know if any people here has a paper or report about Oracle BPM 11g and big scenarios with many instances. If anybody has a case too, it will be relevant.
Another and the final question: how does the oracle bpm engine treats the case when my engine reboots and before that the engine had many instances active? The istances will be lost?11g ADF is not certified with 10g SOA Suite. What I mean by this is that your 11g ADF will need to run on WLS 10.3.1 and SOA Suite 10g will eith run on oc4j or WLS 9.2.
ADF is just JDeveloper, you deploy to WLS 11g (10.3.1).
This is the most detailed 10g SOA Suite guide I know for 10g

note that it is for 10.1.3.3, you just need to subsitute for 10.1.3.5 (latest release)

Macbook Air - White/Grey Screen with a folder and a question mark
Out of the blue , my macbook air stopped starting up and strted to show me a white/grey screen with nothing but a folder and a question mark . After searching on the internet for solutions and trying to reset my PRAM setting , it still wouldn't boot up . I opened up disk utility and going through internet recovery , I ran the first aid verification on my MAC OS X Base System and it said that it found no problems . I can't restore or erase by the way and i really wouldn't erase my files as I have very important files on my mac . Moving on , I tried to reinstall OS X , but apperently it needs a disk to install OS x on and since none appear , I tried using an USB . After creating a partition and erasing everything on my USB , not happy about that , it wasn't big enough for the OS . So now I am basically stuck in the mac white screen Limbo .
Any sort of help would be fantastic and please do keep in mind that this is a macbook air and I do not have a place to put DVDs into . All I have read on different forum pages didn't help so i decided that it would be a good idea to create my very own thread .

Performance issue and functional question regarding updates on tables
A person at my site wrote some code to update a custom field on the MARC table that was being copied from the MARA table. Here is what I would have expected to see as the code. Assume that both sets of code have a parameter called p_werks which is the plant in question.
data : commit_count type i.
select matnr zfield from mara into (wa_marc-matnr, wa_marc-zfield).
update marc set zfield = wa_marc-zfield
where werks = p_werks and matnr = wa_matnr.
commit work and wait.
endselect.
I would have committed every 200 rows instead of every one row, but here's the actual code and my question isn't around the commits but something else. In this case an internal table was built with two elements - MATNR and WERKS - could have done that above too, but that's not my question.
DO.
" Lock the record that needs to be update with material creation date
CALL FUNCTION 'ENQUEUE_EMMARCS'
EXPORTING
mode_marc = 'S'
mandt = sy-mandt
matnr = wa_marc-matnr
werks = wa_marc-werks
EXCEPTIONS
foreign_lock = 1
system_failure = 2
OTHERS = 3.
IF sy-subrc <> 0.
" Wait, if the records not able to perform as lock
CALL FUNCTION 'RZL_SLEEP'.
ELSE.
EXIT.
ENDIF.
ENDDO.
" Update the record in the table MARC with material creation date
UPDATE marc SET zzdate = wa_mara-zzdate
WHERE matnr = wa_mara-matnr AND
werks = wa_marc-werks. " IN s_werks.
IF sy-subrc EQ 0.
" Save record in the database table MARC
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
EXPORTING
wait = 'X'
IMPORTING
return = wa_return.
wa_log-matnr = wa_marc-matnr.
wa_log-werks = wa_marc-werks.
wa_log-type = 'S'.
" text-010 - 'Material creation date has updated'.
wa_log-message = text-010.
wa_log-zzdate = wa_mara-zzdate.
APPEND wa_log TO tb_log.
CLEAR: wa_return,wa_log.
ELSE.
" Roll back the record(un save), if there is any issue occurs
CALL FUNCTION 'BAPI_TRANSACTION_ROLLBACK'
IMPORTING
return = wa_return.
wa_log-matnr = wa_marc-matnr.
wa_log-werks = wa_marc-werks.
wa_log-type = 'E'.
" 'Material creation date does not updated'.
wa_log-message = text-011.
wa_log-zzdate = wa_mara-zzdate..
APPEND wa_log TO tb_log.
CLEAR: wa_return, wa_log.
ENDIF.
" Unlock the record from data base
CALL FUNCTION 'DEQUEUE_EMMARCS'
EXPORTING
mode_marc = 'S'
mandt = sy-mandt
matnr = wa_marc-matnr
werks = wa_marc-werks.
ENDIF.
Here's the question - why did this person enqueue and dequeue explicit locks like this ? They claimed it was to prevent issues - what issues ??? Is there something special about updating tables that we don't know about ? We've actually seen it where the system runs out of these ENQUEUE locks.
Before you all go off the deep end and ask why not just do the update, keep in mind that you don't want to update a million + rows and then do a commit either - that locks up the entire table!The ENQUEUE lock insure that another program called by another user will not update the data at the same time, so preventing database coherence to be lost. In fact, another user on a SAP correct transaction, has read the record and locked it, so when it will be updated your modifications will be lost, also you could override modifications made by another user in another luw.
You cannot use a COMMIT WORK in a SELECT - ENDSELECT, because COMMIT WORK will close each and every opened database cursor, so your first idea would dump after the first update. (so the internal table is mandatory)
Go through some documentation like [Updates in the R/3 System (BC-CST-UP)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCSTUP/BCCSTUP_PT.pdf]

<Personal Information Edited by Host>First, remove your personal information from your post. That's not needed here. This is a public forum, and it is unwise to provide your personal data online.
Second, here's how you reset your password and/or security questions.
How to reset your Apple ID password.
Go to iforgot.apple.com and type in your Apple ID, then click 'Next'.
Verify your date of birth, then click 'Next'.
You'll be able to choose one of two methods to reset your password, either E-Mail Authentication or Answer Security Questions.
If neither method works, then go to https://getsupport.apple.com
(If you see a message that says 'There are no products registered to this Apple ID, simply click on 'See all products and services')
Choose 'More Products & Services', then 'Apple ID'.
A new page will open.
Choose 'Other Apple ID Topics', then 'Lost or forgotten Apple ID password'.
Click the blue 'Continue' button.
Select the contact option that suits your needs best.
How to reset your Apple ID security questions.
Go to appleid.apple.com, click on the blue button that says 'Manage Your Apple ID'.
Log in with your Apple ID and password. (If you have forgotten your Apple ID password, go to iforgot.apple.com first to reset your password with a password recovery email)
Go to the Password & Security section on the left side, and click on the link underneath the security questions that says 'Forgot your answers? Send reset security info email to [email]'. This will generate an automated e-mail that will allow you to reset your security questions.
If that doesn't work, or there is no rescue email link available, then click on 'Temporary Support PIN' that is in the bottom left side, and generate a 4-digit PIN for the Apple Account Security Advisor you will be contacting later.
Next, go to https://getsupport.apple.com
(If you see a message that says 'There are no products registered to this Apple ID, simply click on 'See all products and services')
Choose 'More Products & Services', then 'Apple ID'.
A new page will open.
Choose 'Other Apple ID Topics', then 'Forgotten Apple ID Security Questions'.
Click the blue 'Continue' button.

Hi, I have a new computer and new apple id. I've purchased music with my old computer, email and apple id.
I cant access now the previously purchase music, because it wants to authorize the new computer to play the
music. I cant remember password and security questions for my old id and the old email doest exist anymore.
What can I do?Hi, Carmen.
Thank you for visiting Apple Support Communities.
If you need to reset you security questions, do not know the answers and no longer have access to that email account, see the last sentence under Note in step 5.
You'll be asked to answer 2 of your 3 security questions before you can make any modifications. If you are unable to remember your answers, you can choose to send an email to your rescue email to reset your security questions.
Note: The option to send an email to reset your security questions and answers will not be available if a rescue email address is not provided. You will need tocontact iTunes Store support in order to do so.

Spam filtering solution for iPhone and a question.
I've read a lot of posts about spam filtering for the iPhone and have yet another solution and a question. I use SpamSieve and I am not affiliated with them in any way. The nice thing about SpamSieve is that if it is the first rule in your Mail.app rule set any mail that follows has already been filtered. All you need to do then is create another rule that redirects email to what ever mail account you choose. Since my ISP allows multiple accounts, I will simply create an iPhone@myISP account.
Now the question. Is it possible to write an applescript that will turn the redirect rule on or off so that I don't have to dig into the rules section of Mail to get this done?

Somebody help me My Mac is lagging big and whenever I click on something it just goes to the spinning wheel of death I can't do anything I need help
What model year Mac and what version of OS X are you running.
If this is on an older Mac with standard Rotating HDD it could be a sign the HDD is either to full of data or it is starting to fail. It could also be caused by 3rd party software you've installed. -
I did the back up as instructed... Installed a larger hard drive and followed the restore instructions... Now I get a white screen with a folder icon and blinking question mark. When trying to set startup with new drive I get a bless tool error... Help!!
If you have installed a new hard drive , you will need to have formatted it in Disk Utility correctly. This may explain your problem.
Boot into your 10.6 Install disk again at the top menubar > Utilities > select Disk utility and in there select your new hard drive, and select the tab Erase and choose to make the format as Mac OS Extended Journaled. When that is finished look in the main window to make sure that the partition map scheme says GUID Partition Table.
Now go to the Restore tab and reinstall from your backup. -

It can be downloaded at http://www.ebookmall.com/ebook/277772-ebook.htm.Hi Dan,
Thanks for your observation, comment and review.
1. As a matter of fact, since many features of SAP B1 has not changed, just as you asserted, I took cognizance of new enhancements to the solution over the various releases, especially as it relates to the functionalities. By extension however, most questions for prior releases applies to the successor release.
Furthermore, there was a mix-up in the download. Ideally, you should have three sections in the book. Section I (release 2004, by extension - 2005 and 2007 releases); Section II (release 2005, by extension - 2007 release) and Section III (release 2007). The document has been reviewed. Hence, everyone that bought the book before 29th of April 2008 should visit my [blog|http://blogs.ittoolbox.com/sap/kehinde/archives/sap-business-one-solution-consultant-ebook-review-notice-24053] on how to get a copy of the revised version within 24 hours at no extra cost. I regret any inconveniences. PLEASE DO NOT LEAVE YOUR EMAIL ADDRESS ON THIS FORUM.
2. On localization, SAP Business One has more than 10,000 installations across the world. The book is not intended to be "localization specific". It is intended to serve as a certification review for functionalities that cuts across board with a mix of localized functionalities. I am sure you found in there a number of localization questions for other countries like UK. My advice for individuals using the book is to identify which questions apply to their localization.
While I await your review of the [revised version|http://www.ebookmall.com/ebook/277772-ebook.htm] as an SAP Business One advisor, I believe you will agree with me that it is an invaluable resource for preparing for the certification exam and also technical interview sessions.

Flash Security Settings and Random Questions not Displaying
Hey folks,
I created a Captivate 4 project with 3 slides and a question pool of about 70 questions in which I am randomly pulling in. I am using IE7 and Flash 10. Publishing in Flash 10. If I publish or view in Preview in a web browser the project launches, plays the first 3 slides, and then goes blank when the first question should appear. Note: previewing the project AND publishing the project as an .exe does launch and display all the questions correctly. It ends up being a flash security issue. I went to the adobe site and via the Adobe Flash Player Security Manager" I entered in the main .SWF captivate-generated file as a trusted file and then re-ran the published captivate project and it ran correctly. Question is ... what do I need to do to set up flash or my project so I don't have to do this for every new project that I deploy? I don't want to have the users have to go in and add whatever I deploy as a trusted file. It's also a little confusing as to why the first three slides played and it stopped at the questions ... seems like if it's not a trusted file, that it wouldn't run at all.
Thanks for any help!
ChrisHello again
I think I'd be investigating a temporary web server to host on until things are ready. Here's where it will help.
By providing files to the end users, if you are copying files over you end up having to explain how to save the files. You then have to walk them through setting the Flash Security so they can properly view. It all just becomes a pain in the kazoo.
If you can find some server space, you simply upload the content and provide a link for the users to view the content.
Other than that, if you are insistent that copying is the way to fly, I might suggest you establish a known location where you want everyone to copy their files. Perhaps C:\TestFolder. Then provide some instruction on how to configure the folder with the relaxed Flash Security. From there forward, anything they copy to the folder should need no security adjustment.
Cheers... Rick
