Error converting DOM nodes into SOAP nodes

Question

Hi,
i am doing an http call using http binding activity in oracle soa suite 11g.The http call requires some header information.When I pass the header information through headers in invoke activity and invoke the http call,I get an error " Error converting DOM nodes into SOAP nodes".What might be the reason and how to solve it.

Hello,
It appears your code is trying to repeat messagePart itself. Split Joins strictly adheres to a WSDL definition for incoming and outgoing messages.
Instead of repeating <RootElement> which is defined as single occurance in your message definition within WSDL, you should find a way to tweak the WSDL to have "repetitive node which will become single message after split" within 1 Root element.
This will call for having need of implementing transformation within split join based on need of target input message. Below is the example:
WSDL contains:
<wsdl:message name="inputMessageName">
     <wsdl:part name="partInput" element="rootElement"/>
</wsdl:message>
What your current xml structure is(please note how message itself is repeating below while it has been defined as single in wsdl, unfortunately there is nothing maxOccurs for message in WSDL definition , although you can define multiple parts but that is not case here):
<soap:Body>
<rootElement>
</rootElement>
<rootElement>
</rootElement>
<rootElement>
</rootElement>
</soap:Body>
What Split-Join expects(If you have existing wsdl then you need to tweak it to conform to below kind of structure then use transformation within split join to convert it into correct xml structure for outgoing):
<soap:Body>
<rootElement>
     <repetitiveElementSpecificToIndividualSplitRequest/>
     <repetitiveElementSpecificToIndividualSplitRequest/>
     <repetitiveElementSpecificToIndividualSplitRequest/>
</rootElement>
</soap:Body>
I hope this helps.
