XML message as input for webservice gives deserialization error

Question

Hi,
jDeveloper 10.1.3
BPEL PM 10.1.2.0.2
Carrental example
Problem:
For the Business Rule Engine I did the Carrental XML example. Based on the java application that connects to the BR engine, I created a webservice in jDeveloper and deployed it to my localhost AS 10.1.3. The webservice has a testRule method that accepts a String buf as input. For now, the only thing the webservice does is return a 'do nothing' string. This works fine:
When deployed the testpage generates the following SOAP message:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="http://carrental/types/">
<ns1:testRuleElement>
<ns1:buf>my xml message</ns1:buf>
</ns1:testRuleElement>
</soap:Body>
</soap:Envelope>
The SOAP response is:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://carrental/types/"><env:Body><ns0:testRuleResponseElement><ns0:result>do nothing...</ns0:result></ns0:testRuleResponseElement></env:Body></env:Envelope>
In BPEL Designer I create a new asynchronous process ValidateBR, with a partnerlink for the webservice, based on the following WSDL file:
<definitions

I defined the process variable inputVariable to be defined based on the carrental.xsd schema. I assign the inputVariable to the 'buf' parameter of the webservice as shown below in the ValidateBR.bpel

FYI: the webservice only contains a return "do nothing"
Question:
What is the proper way to assign an XML message to the web service?
Any help would be appreciated.

Hi,
Reading only is not possible..
I will be still more clear in my question this time..
I have deployed my bpel. My receiveInputVariable is of type xsd:string.
So when i run the bpel in my console, i will be asked to give input as string data.
So when i go to the XMLView, it will be like this.
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
     <soap:Body xmlns:ns1="http://xmlns.oracle.com/Sabari_POC_Appln/DOM_Parser/ConvertToBLOB">
          <ns1:process>
               <ns1:input></ns1:input>
</ns1:process>
</soap:Body>
</soap:Envelope>
Now, i am going to give my input like this. --- which leads to error.
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
     <soap:Body xmlns:ns1="http://xmlns.oracle.com/Sabari_POC_Appln/DOM_Parser/ConvertToBLOB">
          <ns1:process>
               <ns1:input>
*<?xml version="1.0" encoding="UTF-8"?>*
*<projects>*
*<project id = "BP001">*
*<name>Banking Project</name>*
*<start-date>Jan 10 1999</start-date>*
*<end-date>Jan 10 2003</end-date>*
*</project>*
*<project id = "TP001">*
*<name>Telecommunication Project</name>*
*<start-date>March 20 1999</start-date>*
*<end-date>July 30 2004</end-date>*
*</project>*
*<project id = "PP001">*
*<name>Portal Project</name>*
*<start-date>Dec 10 1998</start-date>*
*<end-date>March 10 2006</end-date>*
*</project>*
*</projects>*
</ns1:input>
</ns1:process>
</soap:Body>
</soap:Envelope>
This xml is not accepted as string input.. so kindly suggest me some other solution.
I also tried.. like.. making my receiveInputVariable of type xsd:anyType, it also dint help. same error occurred.
Thanks,
Sabarisri. N
