Select does not recognizes subelement/nodes in xml

Problem:
Querying(or update) xml using xpath recognizes only the root node, and ignores all of the subnodes.
What was done:
1. I created and registered xml schema using dbms_xmlschema
2. Created a table with xmltype column refeencing above schema
3. Inserted xml into the table successfully into 9.2.0.1.0 DB
Has anyone necountered similar problems? Any suggestions?
Thanks!

Hi,
We need to see the commands you are issuing in order to provide more help.
By default, XDB only does a "partial" validation on structured XMLType tables. For full validation you would need to code a CHECK constraint or a BEFORE INSERT trigger. The link below provides more information:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb03usg.htm#sthref318
It sounds like you are targetting XML nodes that don't exist, both in your update and select commands. Oracle doesn't consider that an error and if it doesn't find the nodes, then it merely returns NULL or doesn't update anything. You can test for nodes with existsnode() prior to firing the statements or simply test the results of the SQL statement after.

SAP App Server 7 does not recognize DOM mechanism of XML security provider

Hi all,
I am trying to do XML signature by Java servlet, and am using Sun WSDP 2.0 (WebServices Developers Pack) for this purpose.
SAP Netweaver 7.0 (which implements Servlet API version 2.3) on Windows2003
JRE 1.4.2
SAP Developers Studio
SWSDP 2.0
Code snippet:
import javax.xml.crypto.dsig.XMLSignatureFactory;
XMLSignatureFactory sigFactory =
XMLSignatureFactory.getInstance("DOM", new org.jcp.xml.dsig.internal.dom.XMLDSigRI());
This gives an exception:
javax.xml.crypto.NoSuchMechanismException: Cannot find DOM mechanism type
This means that the SAP app server cannot get DOM mechanism from the provider (org.jcp.xml.dsig.internal.dom.XMLDSigRI).
I tried the same code in a stand-alone Java program, and it worked perfectly. Again, the same program when loaded on tomcat also worked. I tried with JWSDP 1.5 and the results were same (ie. worked on tomcat, worked in a stand-alone java program, but failed in SAP app server).
Does anyone know or have any idea of this issue? Why is the SAP app server rejecting the DOM mechanism of other provider? Is this a bug?
To recreate this issue, just download the xmldsig.jar for the package JWSDP2.0 (or 1.5) and write the above 2 lines in the servlet.
Thanks in advance.

This problem is solved. I am putting the reply here so that others who stumble upon this error can benefit.
Add the following line to explicitly include the provider before the getInstance
Security.addProvider(new org.jcp.xml.dsig.internal.dom.XMLDSigRI());
XMLSignatureFactory sigFactory =
XMLSignatureFactory.getInstance("DOM", new org.jcp.xml.dsig.internal.dom.XMLDSigRI());

My Apple TV 2 does not recognize my laptop (Win 7), but I can select Apple TV speakers in ITunes

I am setting up my Apple TV, and cannot recognize my Laptop.
At first it showed it, but could not access it, now it just does not show it, I checked they are both on the same wifi, I have Home Share settings activated on both, but it still does not recognize it.
If I play music (radio) on Itunes in my Laptop, I can select to use Apple TV speakers, so they are communicating.
Please help.

IMovie 6.0.3 does not recognize built in iSight Camera on new iMac

New iMac, Intel, OS 10.5.4, QT 7.5.
Built in Camera works with Photo Booth, the new iMovie 7.1.3 and iChat.
iMovie HD 6.0.3 or 6.0.4 does not recognize the camera. Opening a new project results in a No Camera Connected error. I have tried selecting various options in the video format drop down when creating a new project. I have repaired permissions, tried it under various users, removed the imovie plist, reinstalled imovie (both 6.0.3 and 6.0.4) without success. All 10 of the new computers are exhibiting this problem.
Any help would be appreciated.

That is not an option that I can select on the imac's. On my iBook under 10.5.4 with iMovie HD 6.0.3 or 6.0.4 I can click on the triangle next to the camera icon and select the built in iSight camera. On the new iMacs that does not work. The built in iSight is not listed as an option.

Report Generation Toolkit does not recognize Office 2003

Hi there
The newly installed MS Office 2003 and LV 8.5.
When installing Report Generation Toolkit is screams that it does not recognize Office 2003:
"Microsoft Office version 2000 or higher was not detected on the system. You need to install Microsoft Office 2000 or higher before you install the NI Report Generation Toolkit for Microsoft Office 1.1.2."
What to do?
thanks
Pawel

Did you reboot your system after installing Office 2003? Have you launched Word and/or Excel since installing Office 2003? I think there might be some registry initialization that takes place on first launch of Word and Excel. If you've launched Word/Excel and the RGT 1.1.2 installer still isn't detecting them, there may have been a problem with your Office 2003 install. Try uninstalling Office 2003 and reinstalling it. When you reinstall, double-check that Word and Excel are selected in the install. Then launch them both a first time before trying to install RGT 1.1.2. If it still doesn't detect Office 2003, perhaps there's another problem with your system. Are you using any foreign language software? What OS are you running? Is it Office 2003 standard or professional? Is there anything weird about your Office install, like is it installed over the network instead of from CDs?
I'm hoping the answer to one of these questions helps you solve the problem. Keep me posted...

Is there an issue with Safari in Iphones and Ipads where it does not recognize option disabled="disabled" tag properly?

Greetings everybody,
I have run into a peculiar problem with the Safari browser on mobile platforms (IPad, IPod, IPhone) which I hope I can find a solution for in this community.
I just launched a new website where I sell products with certain variations, for example please view this link: http://www.finerribbon.com/aegean-single-face-satin-ribbon.html
On this particular product, the product variants are supposed to work in such a way where:
If you select the value "1/8" from the "Choose Ribbon Width" field
THEN
The only options active and available to choose from in the "Choose Roll Size" field should be: 500 Yds, 20 Yds & Sample Swatch
Now, if we browse to the above link in Safari using a desktop or a laptop, there are no problems at all, but if we browse to the above link using an IPhone or an Ipad, then we have a problem where all the options are available regardless of the values chosen, basically the above functonality does not work.
I was told that there an issue with Safari in Iphones and Ipads where it does not recognize option disabled="disabled" tag properly, is this true? Can anyone advise me if there is a solution to this problem? I would sincerely apperciate it.
Thank you very much for your time and help!

I suddenly cannot email photos from iphoto. I get a box that says "server does not recognize username or password". I now have to use regular email and cannot re-size my photos.

Suddenly I can no longer email photos directly via iphoto mail. The box comes up that says "server does not recognize username or password". I used to be able to re-size my photos before sending so that they jpeg or pixels were larger for publishing in newspapers or magazines, but I can no longer do that. Apple tech support told me to change my iphoto "preferences" to using regular email to send. But that does not allow me to re-size. Is anyone else having this problem? I don't know if there was an update that caused this or what? Please help.

The box comes up that says "server does not recognize username or password".
That error message usually will pop up, when there is a conflict between the "From" setting for the mail account you are sending from and the selected outgoing mail server. Probably the outgoing Mail server is receiving a user name and password it does not understand. When the mail returns unsent, do you see the "Try again" panel with the option to select a different outgoing mail server?
If you do not see this panel, change the Mail "Preferences > General" to "If Outgoing server is unavailable: Show a list of alternate servers". This way, you will know, which server Mail is trying to send from.
Have you tried to set "From" pop-up menu to one of your other email addresses? If that works, change your settings in Mail to always send from this address. You can set this option in the Mail "Preferences > Composing: Send New Messages from". I have my "Send New Messages from" set to "iCloud". That is working best for me with iPhoto.

My ipod 1st gen battery went totally dead because the usb cable was defective. I've changed the cable. now when i connect my ipod to the netbook, itune is not launching automatically and windows does not recognize it......how can these issues be resolved

My ipod 32gb 1st generation battery went totally dead because the usb cable was defective. I have since replaced the cable but now itune will not launch automatically as it did before and windows xp does not recognize it. Nonetheless it is charging. However can i resolve these issues bearing in mind that i am not tech savvy?

have since replaced the cable but now itune will not launch automatically as it did before and windows xp does not recognize it.
Try disabling a/v software and turn off the Firewall on your PC.
Disable antivirus software
Turn-Windows-Firewall-on-or-off
Then connect the iPod to your computer. Launch iTunes. If your computer still won't recognize the iPod check out this article.
http://support.apple.com/kb/TS1538
Once your iPod is functioning again, with it connected to your computer, launch iTunes. Select the iPod under Devices in the source list on the left.
Select the box next to: Open iTunes when this iPhone is connected
That way iTunes should open automatically when you connect your iPod to your computer.
And iTunes / Preferences - Devices. You can have your iPod sync automatically whenever it's connected from the Devices pane.

I connected my sons Ipod Touch to my pc and it worked fine. Now, when I try to connect my iPad the following message comes up: One of the usb devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.
I checked the cable. It surely is not the cable. If I connect the iPod again it works fine. If I use the same cable with my pc and ipad at work or my other son’s laptop, it is working perfectly. It is only on my laptop where the iPod was connected. Something tells me it got something to do with the drivers that went corrupt or something when I connected the iPod.
I searched the internet and I see a lot of people gets this message. Still no solved answers yet. Is there a place where I can download the drivers again or any other suggestions?

I was hoping it would be something like a USB device conflict, but now the shuffle is the only thing connected...
This article was one of the ones you linked to above in your initial post
http://support.apple.com/kb/TS1369
Under Part 9. Verify that USB drivers are installed, did you try the steps in If only "Unknown Device" appears? That appears to be your situation.
Also, you said that the shuffle initially worked well enough to do a sync, then it had the same problem again. If you can get it to work again initially, before doing anything else, try the following. Select the shuffle in the iTunes sidebar, under DEVICES. Over to the right, go to the Summary tab. By default, the checkbox for Enable disk use should be unchecked. If so, check it and Apply the change. See if that makes any difference.
(If Enable disk use was already checked, try unchecking it and Apply the change. Basically, set it the "other way" and see if there is any improvement.)
NOTE: When disk use is enabled, you have to eject the iPod in iTunes before disconnecting it physically.
If the disk use change makes a difference, that may provide a clue about the actual cause.

Os10.8 does not recognize hp 4000 printer

My iMac with OS 10.8.4 does not recognize my HP LaserJet 4000tn on my ethernet network. I have downloaded Apple's latest version of HP printer drivers 2.14. Have been on the phone with tech support-not helpful. Have tried to connect with USB cable...no diffence. Entered the IP address and found the printer on the pull down but received the message "Unable to verify the printer on your network." I would really like to continue to use this printer with my new computer. Is there a solution?

Just to add more detailed info on hooking it up via Ethernet. This is for a 5000N, so the finding and printing out the IP address of the printer may be a bit different, but otherwise should work the same.
1) At the printer. Press the Menu button to the right once so the display reads, "Information Menu". Press the Item button twice to the right so the display reads, "Print Configuration". Press the Select button. The printer will kick out two sheets. On the first page under the "Printer Information" heading is the IP address for your printer. It's the second entry from the bottom labeled, "HP JetSend Address: ip: 192.168.5.6 (your actual address will of course be different).
2) In the "Print & Fax" heading of the System Preferences, remove any entries for the 5000. Click the Add button and then the IP button. Under the Protocol pull down menu, choose "HP Jet Direct - Socket". Under "Address:", enter the IP address on your printout, like my example of 192.168.5.6. Under "Name:", put in something meaningful, like "HP LaserJet 5000N". Assuming you have the PPD installed, then under "Print Using:' choose "HP LaserJet 5000 Series". Click the Add button.

Premiere Pro CS6 does not recognize USB PnP Sound device connected to iMac OSX even when activated in Audio MIDI setup. The iMac(i-7 processor,16 GB) is working with this USB device without any problem

Premiere Pro CS6 does not recognize the USB PnP Sound device in order to produce a commentary sound track. The USB device has been activated on the iMac OSX by using the Audio-MIDI-setup and is working correctly with the iMac. When opening > presets >audio hardware I can only select between >standard >out integrated > digital input integrated >microphone integrated. USB PnP is not indicated at this place.
With the built-in microphone of the iMac I can produce the commentary sound track, but I would prefer a stand alone version for better quality.
Your help is highly appreciated. Thanks in advance, Annemarie!

I'm using a Logitech Webcam Pro 9000 (which has a microphone on the side). I have several other devices plugged into separate USB slots: a keyboard, a mouse, my iPhone, and a Roland keyboard midi controller.
I've considered that maybe the webcam/mic combo is the culprit. If USB doesn't work at a constant speed, that could very well be causing the issue! The sound begins to lag badly sometimes when it's working properly, so that there's a multisecond delay between speaking and hearing my voice repeated back over the mic which is another sign that something is wrong. I've also caught it making a strange electronic sound during its "hang" time once it stops taking sound input correctly.
Maybe I should try to use line-in and forgo USB altogether then. I think I'd need a preamp and some sort of converter for that since the Mac Mini lacks a powered mic jack. I'm only a newbie musician so I've never set up such a system but it might be a better solution in the long run.
I'll check to see if it hangs before or after my computer enters suspend mode, that's a good suggestion too. Thank you for your help!
