Namespace problem The result is empty for the XPath expression

I have a problem with BPEL namespaces. The webservice that my BPEL process is using has changed namespaces (i.e. the java code package names changed and therefore the namespaces associated with the packages.)
Before there was only one namespace associated with this web services; now there are multiple namespaces.
I have changed the namespaces in my .bpel file; however I get the result is empty for XPath expression:
/nsxml0:getMailResponse/nsxml0:getMailReturn/nsxml1:mailOut
Any help appreciated...:(

hey b-o-s-t-o-n,
have your verified that the namespace import is correct, and with the right prefix
you xpath contains 2 namespace prefixes
/nsxml0:getMailResponse/nsxml0:getMailReturn/nsxml1:mailOut
so check the bpel file and maybe the wsdl that has been generated (that inclused the plnk extensions for your external service)
this is the most common issue ..

The result is empty for the XPath expression

Hi friends
Please, could anyone help-me with this issue? My BPEL process was working yesterday and stoped today...
I think I´m facing a namespace problem.
If I start my process using BPEL Console, filling the "HTML form" option, all works ok.
If my process is started by a call from another bpel process, my XPath query gives me an error, but the 2 received messages are "almost" egual:
Using BPEL Console:
<RejectionMessage>
<part name="message" >
<RejectedMessage ns1:BatchId="" ns1:PrimaryKey="" ns1:RejectionId="invalid_msg_processName_token1_token2_token3" ns1:BatchInfo="" >
<MessageHeader/>
<MessagePayload/>
<RejectionReason/>
</RejectedMessage>
</part>
</RejectionMessage>
Started by another BPEL Process:
<RejectionMessage>
<part name="message" >
<RejectedMessage RejectionId="INVALID_MSG_BatchTest_Read_20060418_101233_0463" BatchId="" BatchInfo="" PrimaryKey="" >
<MessageHeader/>
<MessagePayload> AgICAgICAgICAgICAgICAgIE1aIEpBSVJPUyAg MDYwMzA4MTAwMQ0K </MessagePayload>
<RejectionReason> ORABPEL-11008</RejectionReason>
</RejectedMessage>
</part>
</RejectionMessage>
XPath Query:
bpws:getVariableData('RejectionMessage','message','/ns2:RejectedMessage/@ns2:RejectionId')
In the first case, it works.
In the second case, it raises a "The result is empty for the XPath expression" error.
As you can see, this process is used as a "Rejection Handler" process: It implements the interface defined in RejectionMessage.wsdl
Could you help me?
Thanks in advance

Hi All
I find a workaround to the problem. I´m almost sure it is a bug in BPEL.
As you can see on my previous post, the diferences between the two messages is that the attributes have qualified names on one message and unqualified names on the other: ns1:BatchId, ns1:PrimaryKey...
The schema definition for this message (JCAErrorHandling.xsd) define that attribute names MUST be qualified (attributeFormDefault="qualified"). The problem is that the File Adapter sends the message with unqualified attribute names!!
So I edited JCAErrorHandling.xsd (<ORACLE_HOME>\integration\orabpel\system\xmllib\jca) file, changing it to attributeFormDefault="unqualified".
The correct solution is to fix File Adapter to send the message with qualified names, so I´m opening a Service Request at Oracle Metalink.
Thanks.

Assigning JMS message in BPEL: The result is empty for the XPath expression

Hi,
My project, an Oracle BPEL 11g project, is reading an XML payload from a JMS queue. I would like to transform the message and assign the elements of the messages to other variables. But when I am doing that in the "assign" step, it raises an error: Error in evaluate <from> expression at line "63". The result is empty for the XPath expression : "/ns2:publishProject/payload/Message".
Even though I can see the message payload in the Audit with all the values.
To me it looks like a name space issue, but I could not find out how to correct it. Any hint will be a big help. Please let me know if you want to check the .xsd for the message.

I publish a JMS message to a topic in one BPEL process and have another BPEL process read from the topic and start the flow. The problem I have is that the first process is writing fine to the topic, but the second process seems to be reading twice. I am seeing two instances of the second process in em.
Can anyone help? I am using JDev 11.1.1.1.0
Thanks

Error: The result is empty for XPath expression

hi gurus
Following is my input sample data to BPEL process.
<ItemList>
<Item>
<Name>Music System</Name>
<Id>525</Id>
<Item>
<Name>Fog Light</Name>
<Id>325</Id>
<Item>
<Name>Tyres</Name>
<Id>325</Id>
<Item>
<Name>Neon Light Ring</Name>
<Id>325</Id>
</Item>
</Item>
</Item>
</Item>
</ItemList>
Here <ItemList> contains <Item>.
And <Item> contains <Name>,<Id> & <Item> element itself.
i have created proper XSD for this.
But When i try to fetch any value then using Assign Activityits gives runtime following error.
Error in evaluate from expression at line "36".The result is empty for the XPATH expression: /ns1:ItemList/ns1:Item/ns1:Name
Any suggestion..?
thanks

Result is empty error in XPath

Hi,
I am getting the following error coming from an "Assign" activity that copies from a child element of one variable (child of message type = M1) to another variable (which is of type element same as that of that child of M1).
I am consistently getting the following error :
"Error in evaluate <from> expression. The result is empty for the XPath expression .
<<from element name>> "
Does anyone know why ?
Thanks

That message usually occurs when you point to a non-existing child. When you're using child nodes, you'll have to make sure you're pointing to the right node, for example by using [position() = bpws.getVariableData('idx'), or using an XSLT with a 'for each'.
Post the variable definition and the assign here, if you need more input.
Hth,
Mike

I created a book on iPhoto. I click on the buy button, and I get a connecting message with a blue striped rectangle. I am connected to the internet and I have made books before without any problems. I have tried for the past two weeks at various times.

I created a book on iPhoto. I click on the buy button, and I get a message that says Connecting with a moving blue striped rectangle. I am connected to the internet and I have made books before without any problems. I have tried for the past two weeks at various times and I get this same message each time. Any ideas about what is going on?

First confirm that you can create a PDF file of your book as described in this Apple document: iPhoto '11: Preview a book, card, or calendar before you order or print it. Post back with the results.

E4200 v1- problem creating a shared folder for the FTP server.

Hi,
I'm trying to share an external USB harddrive (4TB- HFS+) that is attached to my e4200 router. I'm trying to set up the FTP server, but when I try to create a shared folder, I get kicked out of the browser based interface for the router just as I'm trying to save the new shared drive. I have tried many different things to get it to work: different computers (PC and Mac) different browsers, reflashing the firmware (which is version 1.0.06, build 3), I tried all of this with an NTFS formatted drive as well- everytime I try to set up the shared folder- right as I hit the save button it kicks me out saying: Session Failure.
I can see my drive on the local network, and I know the FTP server is working, because I can log into it from the outside- but I don't see anything shared, when I do.
I have successfully gotten the media server to work using the same drive- but I can't create shared folder there either... It seems to have shared the entire disk automatically when I first connected the drive to the router.
Anybody have anything else for me to try?
Help!

Same problem. Has anyone found a solution? I contacted tech support and got nonsense responses. I was of course asked to Factory Reset even though I told them I had done it before I called - classic brush off. Basicly here is the problem.
1. I cannot create a share on a USB connected HDD - this worked on the older Firmware. Now every time I try to set up the shared folder- right as I hit the save button it kicks me out saying: Session Failure. I am not the only person with the problem. Crazy thing is I had a share created and it worked after the upgrade. I wanted to add an additional share and now it wont share anything. HDD plugged into my PC works great. I was asked to try a different PC - even though I told them I tried from IE, Chrome, Firefox on a Windows 7, Vista, windows XP, IPad, Kindle and Samsung phone.
2. While troubleshooting with the agent I discovered that although I have remote access disabled in the Administration>Management page but I can still access the router remotely. This is a huge security issue.
3. Linksys is no longer a Cisco Company - if the code is this bad Belkin should take the Cisco logo out of the GUI. Don’t blame Cisco for your poor SW.
I am ready to buy a new router and avoid Linksys and Belkin all together in light of these issues.
Additionally, I would simply downgrade but the older Firmware is not available. When I asked for it I was told I could not get it.

There is an invalid number of result bindings returned for the ResultSetType

SSIS SQL Task: Single Row Result Set
Code was updated to test for data in target: If Exists Do Merge ELSE Do Insert

The T-SQL merge allows both inserts and updates:

THEN DELETE
OUTPUT $action, inserted.*, deleted.*;

I am having trouble with the initial connection of the apple tv. I have isolated the problem to the cable/connection. My new hdmi cable has a resolution up to 1080p...does the resolution matter?is this the right hdmi cable for the apple tv?

There are only two types of HDMI cables (standard and high speed - listen to all 1.2, 1.3 etc etc nonsense they will try to tell in the store) both types will work with the Apple TV.
The cable may be faulty though, have you got another to try, what exactly is happening.

"The upload has failed.

This is the message i get when tryng to update
any ideas?

Error: "svr.VirusScanExecutionError"
An intermittent problem with acrobat.com's underlying virus scan component causes this issue. This issue happens occasionally on a small number of server instances.
The solution is to update the article again. Trying again typically routes you to a different host in the server array.

If you are printing via a Windows shared printer and it is the Windows user account that you are being prompted for then you can save this in the Keychain, as shown below.

When starting imovie I get an error missing quicktime components. To solve the problem I have upgraded to latest version but it didn't help. I want to either solve this problem or get a refund for the useless upgrade.

Mac OS X 10.6 includes QuickTime versions 10.0 and 7.6.3. The QuickTime 7 player will only be present if a QuickTime Pro key was present at the time of installation, or if specified as part of a custom install, or individually downloaded:
http://support.apple.com/kb/dl923
Snow Leopard update 10.6.4 included an update to 7.6.6 (if installed). You can install it from the above link even though it says for 10.6.3. It's the same version of QuickTime Player 7.6.6.
(Only QuickTime Player 7.6.3 or 7.6.6 can be updated to "Pro".)
iMovie does not, AFAIK, use QT 10.

Getting the result ALV ready for input to be able to maintain the result

Hi guys,
i did follow and implement this program to mass maintain variables in a broadcasting setting and save the new values back.
The program allows maintenance of infoobjects or variables via the selection screen. What i want to have is just to select a or many broadcast settings. After executed i can see all infoobjects, variable names and variable values in an ALV. The values for the variables used in the broadcast settings all begin with var_value then the value of that variable.This is the value i want to change therefore i need to have all fields after var_value input ready and maintainable there.
How can i get these field editible?
The thing is that the ALV result looks like
Var_name_1 name of variable 1
Var_name_2 name of variable 2
Var_name_3 name of variable 3
... so on till all variable names are listed in rows
Then further below the all the variables get their value.
Var_value_1 value for the variable_1
Var_value_2 value for the variable_2
Var_value_3 value for the variable_3
... so on till all variables have their value.
All these rows are not editable as a result of ALV. I want the Var_names be not editable as it is now but i want the Var_value fields be editable so we can change them in the ALV result and save them back.
How can i do this approach?
Any help, idea, hints appreciated.
Thanks and kind regards,

This issue is solved.

Try a reset of the printing system. This often resolves the symptom you are experiencing.

Then use multipel 99 picture slideshows.
You can have up to 8 or 9 slideshows per menu. If you add a sub menu reduce that by 1 and add 8 more to the sub menu. The top menu can have links to up to 8 or so submenus (depends on the theme) and each submenu can have up to 8 or so slideshows.
However, converting a very large slideshow to a QT movie as Terence suggested does not envoke the 99 slide limit in iDVD. It just becomes a single video/movie file. So you should not have a problem with exporting at the large size, 720 x 540,
and dragging the resulting file into the iDVD menu being sure to avoid any drop zones.
