Bpel xpath query

Hi,
My wsdl contains:
<wsdl:message name="BPELProcess1RequestMessage">
<wsdl:part name="payload" type="xsd:string"/>
</wsdl:message>
<wsdl:message name="BPELProcess1ResponseMessage">
<wsdl:part name="payload" type="xsd:string"/>
</wsdl:message>
In my soap request I am sending xml as part of soap body as string:
<soap:Body>
<Test>
<TestRequest>111</TestRequest>
<TestType tc="99">
</Test>
</soap:Body>
So in my bpel I want to access tc value i.e 99. Could you please share some sample code to access this attribute value. appreciate your quick inputs.
thanks

first i would recommend changing the wsdl to have right complex type for the part instead of using xsd:string. once that is done, then you can use /Test/TestType/@tc to get the value of tc attribute. by using the complex type you can validate the incoming documents and eliminate other xpath syntax errors.

Copying Variables in BPEL using XPath Query

Hi,
I am new to BPEL and i want to know if it is possible to copy data from one variable to another using XPath Query in the <from> <to> tags, when the two variables are of different message types.
I am trying to create a sample BPEL that would receive a String through the receive tag tied to one partner link (WSDl) and then invoke a different webservice using the <invoke> tag tied to another partner link (WSDL) by passing the received variable.
I have pasted the BPEL File and the two WSDl files involved.
My Issue is that when I send a soap request to the BPEL, it is passed as null to the webservice invoked.
Probably because the copy tags don't work.
Please help.

Hi,
Yes, it very much is possible.
Xpath query provides a lot many data type conversion functions(string to int, string to date etc), which can be used in copying variables.
thanks

Error while executing BPEL xpath extension function : doXSLTransformForDoc

Hi All,
I have used the transform activity in BPEL that uses 2 input variable and one target variable and process gets complied successfully. However, when the is deployed on the SOA server and tested then I get the following error :
=======================================================================
<faultType>0</faultType><subLanguageExecutionFault xmlns="http://schemas.oracle.com/bpel/extension"><part name="summary"><summary>XPath expression failed to execute.
An error occurs while processing the XPath expression; the expression is ora:doXSLTransformForDoc('file:/C:/JDeveloper/mywork/xsl/tranform_02.xsl',bpws:getVariableData('ListOfInterestVariable'),'receiveInput_Consume_Message_InputVariable.body',bpws:getVariableData('receiveInput_Consume_Message_InputVariable','body')).
The XPath expression failed to execute; the reason was: internal xpath error.
Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
</summary>
</part><part name="code"><code>XPathExecutionError</code>
</part></subLanguageExecutionFault>
========================================================================
Please suggest
Thanks.

That is because the bpel file contains the absolute path to the xsl file instead of the relative path.
ora:doXSLTransformForDoc('file:/C:/JDeveloper/mywork/xsl/tranform_02.xsl' .....
should be
ora:doXSLTransformForDoc('xsl/tranform_02.xsl' .....
As far as I know, this is a bug in JDeveloper for putting this information here. I've removed it using the source view only to find it there again.

Variable Picker generates invalid XPath query

This one seems to be a bug:
When declaring a variable of type "element" (not "messageType") and accessing the variable with the Variable Picker from within the assign assistant, i.e. the following line ist generated:
bpws:getVariableData("testVar","","/tns:TaskMgrTestCaseRequest/tns:input")
The BPEL process can be validated and deployed without an error.
At runtime the following exception is generated:
XPath expression failed to execute.
Error while processing xpath expression, the expression is "bpws:getVariableData("testVar", "", "/tns:TaskMgrTestCaseRequest/tns:input")", the reason is XPath expression failed to execute.
Error while processing xpath expression, the expression is "", the reason is Unexpected ''.
Please verify the xpath query.
Please verify the xpath query.
When working with variables of type messageType, there is no problem. (So I declared a messageType to each element type ...)
Wolfgang

Thanks for the heads up. We will try to kill this bug in the 0.97 release. -Edwin

Xpath query on initiateTaskResponse variable fails

I have a small BPEL process which has a human task , in that when I try to access taskid from initiateTaskResponse message, it throws xpath query is invalid error.
Thanks

Thanks for your Reply,
I can able to browse the variable in JDeveloper at design time. When I try to deploy the process, the server throws error on that assign activity(Selection Failure). So I have changed the assign activity to JavaEmbeeding, but now it throws 'Selection Failure' error at runtime.
I can able to use anyother variables in assign activity.
Thanks in advance,

XPath query must be an absolute path in BPEL2.0 or only BPEL4WS?

Hi,
The 1st version of the BPEL4WS specifies that "For XPath 1.0, the value of the query attribute MUST be an absolute locationPath (with '/' meaning the root of the document fragment representing the entire part)." (under 14.3)
But in BPEL 2.0 I cannot find this rule. I wonder if it is different in this version. Especially, can people write something like this:
//street[@name='blabla']
in the xPath query of an assign activity? or are there any important restrictions on using xPath query for a copy selection?
Please help
Thank you very much

Ok, I've realised i mixed up my partitions. sda1 is with windows, sda3 is the extended one. So i changed rootnoverify(hd0,2) to rootnoverify(hd0,0)
And it shows something entirely different now. For a blink of about 0.5 seconds, it shows:
Booting 'Windows 7'
rootnoverify (hd0,0)
chainloader +1
GRUB loading stage2...
After that 0.5 seconds GRUB goes back to the "system select" screen, the countdown to the default choice goes again, and this whole process loops to eternity...
Problem solved! Frankly speaking, I can't really know why. Everything was solved after I reinstalled both systems. The only difference was that the line makeactive was commented out, not deleted... And I think it is that.

Human Workflow Task XPath query string returns multiple nodes.

I am looking for trouble shooting help for this error. I am no sure if it is a server or jdev issue.
I am running JDev version 10.1.3.3 and console version 10.1.3.1.0 locally.
General information on the BPEL process:
I have a temporary table in Oracle lite that I created items to be review by the user. I created a synchronous BPEL process. The first step in developing this process, I created the straight forward invoke the table to get the records, transform the records with a change the approve flag = "Y", and invoke the table to update the records. Works like a charm. I followed the online tutorial by dropping a human task after the transform, configured the parameters, setup the assignments, and moved the invoke to update table under the approved condition. If the table has only one record, the process runs great but if there are two records I get the following error message.
<selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><part name="summary"><summary>XPath query string returns multiple nodes.
According to BPEL4WS spec 1.1 section 14.3, The assign activity part and query /ns3:TempItemCollection/ns3:TempItem/ns3:ItemNbr should not return multipe nodes.

Thank you for any help you can give me.

Here is how I solved this problem: I was told by the metalink folks that I should use the same verion of SOA console as jdev. So I went back to jdev 10.1.3.1. Rather than reading from the Oracle lite table, I dumped the table into a flat file. I read flat file and populated the workflow. Remember to set the 'messages in batch' flag in the file adapter to 1 and the number of records to skip to zero in the format builder for the flat file. The process now reads each record and creates an instance for that each record. In other words, if I have 8 records in my flat file, I will have 8 instances of the process running on the console. Thanks Jeremy for your help figuring this out.

Error: XPath query string returns multiple nodes

Hi all,
I am facing issue with the assign activity.
Error message:
com.oracle.bpel.client.BPELFault: faultName: {{http://schemas.xmlsoap.org/ws/2003/03/business-process/}selectionFailure} parts: {{ summary=<summary>*XPath query string returns multiple nodes. The assign activity part and query are returning multiple nodes. The assign activity part and query named in the error message returned multiple nodes. It should return single node. According to BPEL4WS specification 1.1 section 14.3, the assign activity part and query named in the error message should not return multiple nodes. Verify the part and xpath query named in the error message at line number 2005 in the BPEL source*.
BPEL code:
<copy>
<from variable="Invoice_Tax_loopCounter"/>
<to variable="Var_Invoice_Tax_Contacts" part="payload" query="/ns30:Invoice_Tax_Contacts/ns30:Invoice/ns29:Get_InvoiceOutput[bpws:getVariableData'Invoice_Tax_loopCounter')]/ns29:ADDR_ATTRIBUTE2"/>
</copy>
We are using SOA 11.1.1.3 version.
Any pointers on this?
Thanks in advance

Hi-
This is because you are have multiple nodes either in source or target XML.
My guess is some nodes of your XML might be repeating (means a single element/node has multiple values). Can you please check that or please post your XML here.

XPath query error - xml extension in schema

Hi,
I am getting following error when i try to assign values to input xml payload before
invoke process.
"{http://schemas.xmlsoap.org/ws/2003/03/business-process/}selectionFailure" has been thrown.
<selectionFailure>
<part name="summary" >
<summary>XPath query string returns multiple nodes. According to BPEL4WS spec 1.1 section 14.3, The assign activity part and query /child::parameter/child::param1 should not return multipe nodes. Please check the BPEL source at line number "40" and verify the part and xpath query /child::parameter/child::param1. </summary>
</part>
</selectionFailure>
The generated XPath resolves to a single node only (tested using XMLSpy). The only reason i can think of is that the xml schema in wsdl is extending a base xml type to a new type.
It works fine if the extending xml type is merged with it's base type, and used as one single complex type.

reg,
Amitoj.

I am also having the xml extension issue and since we are dealing with large WSDL files (exceed 40,000 lines) it would be ridiculous to move all extension classes to the base type (parent class). Has this bugged been looked at and when can it be resolved since it seems to be a major issue in JDeveloper.

Hi,
our system reciving xml data using the datatype xsd[b] <any/> . am sure the system will receive the data in same format[node hierarchical] but the namespace of the root element may be differ..
i want write xpath which should not be parse based on the namespace of element.
like the method setNameSpaceAware(false) in java;
will it be possible in bpel. if so how ?
i would be appreciate any help.
Thanks,
Bogi

Ahhhh - thank you for the clarification.
Regarding the expansion of variable, is there anything further needed? Reason I ask is, when I use the variable which contains the same string as when I hard code the string in the XPATH query, I do not receive the desired results - I only receive the
'VENDOR_ADVISORY' results.

Retrieve xml attribute value of nth xml node using xpath query

I have an xml with following stucture...
<xml>
<header>
<DocumentReference OrderId="order001">
<DocumentReference OrderId="order002">
<DocumentReference OrderId="order003">
I have to loop through this xml and retrieve the orderId values inside Biztalk orchestration.
In the expression shape, I get the count of 'DocumentReference' nodes using an xpath query and then
Added a loopshape to make sure it loops thru all nodes
Loop condition:   n<=nodeCount     (where n is an integer variable, n=0 to begin with, incremented by 1 thru each loop, nodeCount is # of DocumentReference nodes)
I try retrieve to the orderId in the following expression shape using the below xpath query
xpathQuery = System.String.Format("//*[local-name()='OrderReference'][{0}]/@orderID)",n);
sOrderId = xpath(MsgSingleInvoice,xpathQuery);
And I get the following exception:
Inner exception: '//*[local-name()='OrderReference'][1]/@orderID)' has an invalid token.
Exception type: XPathException
Appreciate any help!   thanks!

Thanks for the quick response. I got rid of it.
And I see a different error:
Inner exception: Specified cast is not valid. Exception type: InvalidCastException
Source: Microsoft.XLANGs.Engine
Target Site: System.Object XPathLoad(Microsoft.XLANGs.Core.Part, System.String, System.Type)
Since variable 'n' is of integer type, I suspected it and changed it to n.ToString() and tested again and still see the same error.

XPath Query Language Reference

Aside from the three little examples given in the 11g Guide and the B2B Tech Note #011, is there a reference available for the XPath Query Language used by B2B? Is is possible to use complex XPath queries in the B2B Doc Definitions?

I'm mainly just looking for the full capabilities of the queries.
Specifically, at the moment, I'm looking for a way to match the value of a node to a group of values (like a sql 'in') as well as check the existence and value of other nodes within the same query.
Do the documents I find for 'Preference XPath' pertain here?

XPath query on a CLOB?

Does anyone know if there is an easy way to run an XPath query against a CLOB column? I know it's simple if the column is XMLType, but what if it's a CLOB?

Does CLOB store XML? If so, simply use XMLTYPE(clob_column).

Correct wat to determine if the XPath Query resulted in a match

What is the correct way to determine of the XPath Query
(using e4x syntax) returned matching nodes?
The result is never a null reference even if there are no
matches found, and I can't seem to find a way to determine if the
XMLList returned has any nodes except for a convoluted way like so:
var matchingRecords:XMLList =
xmlData.dataTable[0].dataRow.(@someAttribute == someVariable);
var record:XML = matchingRecords[0]; //This is the part I
don't like to have to do.
if (record == null)
//This means no matches were found.
else
//This means atleast one match was found.

I've been working with Flex since it was beta, and I must
disagree with this. In my experience, the Adobe/MM folks are paying
very close attention to what we say.
You need to understand that you do not modify/release
commercial software casually. It will take months to years. Be
patient, or find a workaround, they exist.
Be sure to log your wishes/bugs on the wishform. I know for a
fact that they monitor that. I have been contacted for
clarifications on my posts there.
