I run WMB 6.1
I have the following scenario:
I accept a Soap message as input into my flow (Wsdl version1);
I send the Wsdl through a compute node to change the Wsdl version as I need a different version to do a call to a 'Validation Engine'.
The two versions of the Wsdl is exactly the same (same operations, same elements) - the only difference is the namespace.
If I put the following message through the compute node, it changes the Wsdl version and namespace, no problem:
Input:
| Code: |
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cus="http://contracts.it.nednet.co.za/services/customer-services/2008-09-20/CustomerValidation">
<soapenv:Header/>
<soapenv:Body>
<cus:AcctChgRq>
<cus:CompanyNo>111</cus:CompanyNo>
<cus:ProductCd></cus:ProductCd>
<cus:AcctNo></cus:AcctNo>
<cus:NewAcctStatus></cus:NewAcctStatus>
<cus:NewCloseDate></cus:NewCloseDate>
<cus:NewPriOfficerCd></cus:NewPriOfficerCd>
<cus:NewSecOfficerCd></cus:NewSecOfficerCd>
<cus:NewEmployeeInd>aaa</cus:NewEmployeeInd>
<cus:NewNameLineNo></cus:NewNameLineNo>
<cus:NewAffinity></cus:NewAffinity>
<cus:NewLanguageCd></cus:NewLanguageCd>
<cus:NewReasonCd></cus:NewReasonCd>
</cus:AcctChgRq>
</soapenv:Body>
</soapenv:Envelope> |
Output:
| Code: |
<NS1:AcctChgRq xmlns:NS1="http://contracts.it.nednet.co.za/services/customer-services/2007-09-08/Customer">
<CompanyNo>111</CompanyNo>
<ProductCd/>
<AcctNo/>
<NewAcctStatus/>
<NewCloseDate/>
<NewPriOfficerCd/>
<NewSecOfficerCd/>
<NewEmployeeInd>aaa</NewEmployeeInd>
<NewNameLineNo/>
<NewAffinity/>
<NewLanguageCd/>
<NewReasonCd/>
</NS1:AcctChgRq> |
...but if I have a input message with embedded elements it seems like it takes the namespaces of the input message and uses it for the output of the embedded elements:
Input:
| Code: |
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cus="http://contracts.it.nednet.co.za/services/customer-services/2008-09-20/CustomerValidation">

<cus:Address>
<cus:AddrLine>aaa</cus:AddrLine>
<cus:AddrLine>bbb</cus:AddrLine>
<cus:AddrLine>ccc</cus:AddrLine>

<cus:DeriveCityFromPostal></cus:DeriveCityFromPostal>
</cus:Address>
</cus:AddrAddRq>
</soapenv:Body>
</soapenv:Envelope> |
Output:

</Address>
</NS1:AddrAddRq> |
...I don't want to see the NS2 to NSx stuff... I don't understand why it would take the input namespaces and produce this kind of output.
My ESQL code that produces this is something like:
| Code: |
DECLARE cval NAMESPACE 'http://contracts.it.nednet.co.za/services/customer-services/2008-09-20/CustomerValidation';
DECLARE cval2 NAMESPACE 'http://contracts.it.nednet.co.za/services/customer-services/2007-09-08/Customer';
...
DECLARE requestOperation CHARACTER Environment.variables.operationName||'Rq';
SET OutputRoot.Properties.MessageSet = 'Customer_2007-09-08_B4.0';
SET OutputRoot.Properties.MessageType = '{http://contracts.it.nednet.co.za/services/customer-services/2007-09-08/Customer}:'||requestOperation;
SET OutputRoot.Properties.MessageFormat = 'XML1';
SET OutputRoot.XMLNSC.cval2:{requestOperation}.*[] = InputRoot.XMLNSC.cval:{requestOperation}.*[];
|
So I guess my question is:
1. Why does it produces this kind of output?
2. How do I get rid of it?
Thanks guys! |

I cannot answer your questions ( not yet, anyway ). But I can help you to diagnose the problem.
- Add two Trace nodes to your message flow, one after the input node, one just before the output node.
- Set the Pattern to '${Root}' on both Trace nodes
- Take a debug-level user trace while processing a message
- Inspect the user trace output. It will show you the message tree contents at the beginning of the flow, what the message flow did to it, and the what the tree looked like afterwards.
- Look very carefully at the namespaces on your elements. |

Thanks for the prompt reply, Kimbert.
OK, I've traced the 'before' and 'after' of the message:

...the one thing that bothers me is that the namespace 'http://contracts.it.nednet.co.za/services/customer-services/2008-09-20/CustomerValidation' is on EVERY level of the output body. What did change, is the mentioned namespace changed to 'http://contracts.it.nednet.co.za/services/customer-services/2007-09-08/Customer', but only for the top-level element. Understandable, because my ESQL explicitly changed it. But the child elements inherits the namespace of the input message.
If I take each and every element of my input message and map it to the corresponding output element, it is fine. But this will be a monster task as I have 80+ operations that I need to handle through this node.
Thanks in advance |

The message tree is like a DOM tree. Every node has its own namespace. You cannot change the namespace for an entire sub-tree just by changing the namespace declaration of its root element.
Sounds as if you need to change the namespace throughout the tree, though. So you need to write some ESQL which recursively walks the message tree and sets the namespace on every element. A long time ago, somebody posted some code to do this, but I think there may have been a defect in it, so I won't link to it. |

Hi,
Try it by declaring the namespace in your root element.
| Code: |
For Eg.
DECLARE S27 CHAR 'http://mqseries.net';
DECLARE S26 CHAR 'http://mqseries.net/1';
SET InputRoot.{S26}:rootElement.(XMLNSC.NamespaceDecl)xmlns:S27 = S27; |

Hi,
Alternative is to perform a transform:
| Code: |
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="no"/>
<xsl:template match="cus:*" xmlns:cus="http://contracts.it.nednet.co.za/services/customer-services/2008-09-20/CustomerValidation">
<xsl:element name="{name()}" namespace="http://contracts.it.nednet.co.za/services/customer-services/2007-09-08/Customer">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet> |

I like paintpot's idea - it's nice and simple.
Be aware, though, that it will be slower than using ESQL unless you put the XMLT node immediately after the input node. |
