How can I get the orclownerguid (unique user number) in Java Portlet?

Hi,
I find a unique number for each portal user in OID, it calls orclownerguid.
And I try to obtain this number in my portlet Java with the JPDK.
How can I get the orclownerguid in Java Portlet with JPDK?
thanks
regards
jerome laforge

Hello,
I just realized that I missunderstood your question.
We have several way to pass (and send) parameter to a portlet:
- OracleAS Portal page parameters that allow the browser user to define the way the parameter is send to the portlet
- generic URL parameter (public parameters)
- private paramter (a parameter that is targetted to a single portlet instance)
In you case, you can use public parameter, but you have to explicitly says that your portlet consume URL parameters, so set the passAllUrlParams tag to true in the provider.xml file.
Also I invite you to read the sample we have in the PDK that show how to use private parameter and page/portlet parameters, and the associated articles you can find on http://portalstudio.oracle.com

hi,
I'm trying to draw a rectagle region on a picture with mouse and crop it. but the rectangle is not vertical along x-axis.that is to say, there is a angle between x-axis and the base of the rectangle. I don't know , how can I do it. Can someone give me some tip or some java-code. Thank you very much in advance.

I completely misunderstood your question. As I read it again it seems clear and straight-forward. I'm sorry. Let's see if this is closer.

How can I get a report with total number of pages printed on my HP Officejet Pro 8610?

Since knowing the number of pages I print is so critical to a choice of using the "HP Instant Ink Plan" or not, how can I find the total number of pages I have printed on my brand-new (installed 2 days ago) 8610? And if I can, is it a "resettable" or rolling total? Don't see anything in user guide and a search yields nothing usable on this blog.
Printer is installed wirelessly on an older PC with Windows XP SP3. I can also of course intstall it with network cable but so far it works OK on my home network without network cable. If it matters which OS, I also have a Lenovo laptop running Vista on which I can install this printer.
Please do not respond that I can find the total by counting the number of pieces of paper I have. Surely the internals of this fine machine must have the requested data so that HP can tell my usage if I select the monthly ink plan!
This 8610 was a good buy (net $89.00 after trade-in of my six year old J36xx Deskjet) at Office Depot/Max which of course influenced my decision to buy it. So far I am very happy with printing qualities and speed, have not tried the scanner yet and will probably never use the fax since I have no land line phone.
Thanks,
Harry

Hi,
Section #2 of the Printer Ststus report will tell you. Please try:
Printer status report
Use the printer status report to view current printer information and ink cartridge status. Also use the printer status report to help you troubleshoot problems with the printer.
The printer status report also contains a log of recent events.
If you need to call HP, it is often useful to print the printer status report before calling.
To print the Printer Status Report
1. From the printer control panel display, touch and slide your finger across the screen and then touch Setup.
2. Touch Print Reports and then touch Printer Status Report.
Regards.

TS1702 I made a request to update an App in my iPad, but I found out that it was not supported. How can I get rid of the annoying number from the App Store now?

I don' t want to loose my data!!

As of the current version, I don't believe there is a way to tell the App Store app to ignore updates. You can send Apple feedback at http://www.apple.com/feedback/, but in short there is nothing you can do. As long as you don't try to update the app (either pressing the update button or update all), the app should continue to work fine with your data remaining intact. It has been a while since I've tried to update an app that isn't supported (last time was under iOS 3 or 4), so I can't comment about what would happen if you did try to update it. (My best guess is it will display an alert saying it is not compatible, and leave the previous version there, but not take away the 'update' in the APp Store app updates page).

How can I get a count of the number of emails in my inbox folder (not just unread, but total) to display on the folder list?

I use to have a count of the total number of emails in my inbox. This was listed next to "inbox" in my folder list. With the latest version, this is gone and I can't find anything in the settings that can bring back that feature. I can see the number of emails by right-clicking the folder, but I'd love to be able to just see it at a glance again.

Do you have this add-on?

How can i get my iphone 5s serial number? its off and i dont have the box

i want to take my iphone to the apple store but they ask for the serial number for the phone and my phone is off doesnt charge and i lost the box

With iTunes on your computer assuming you have synced your iPhone with iTunes and/or backed the iPhone up with iTunes.

You shouldn't need the serial number with taking it to an Apple Store unless it has changed. Your cell phone number should be enough.

The problem is that I can not verify her id on message and on Facetime
has that to do that the ipad has no tel number of course?? Should I leave my id number on her iPad ??
That isn't due to not having a phone number on her iPad. You can use FaceTime with any iPad using an email address as the "phone number". And if her iPad isn't a first generation iPad, if she uses the same Apple ID for FaceTime on both her iPhone and iPad, her iPhone number can be used as well (see iOS and OS X: Link your phone number and Apple ID for use with FaceTime and iMessage).
If her iPad is not verifying her Apple ID for FaceTime it's probably because the Apple servers are busy. Keep trying and it should verify. If you continue to have problems with this, look through the troubleshooting steps here: iOS: Troubleshooting FaceTime and iMessage activation.
