Abstract:  In WSAD-IE, cannot invoke a Web service from xmethods in a BPEL flow

Description/symptom of problem:  
When trying to invoke a Web service from xmethods through BPEL a deserialization problem occurs. The SOAP envelopes that are being sent and being received are:

SENT:
? <?xml version="1.0" encoding="UTF-8" ?> 
- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <soapenv:Body>
- <Translate xmlns="http://www.webservicex.net/">
? <languageMode xsi:type="xsd:string" xmlns="">EnglishToFrench</languageMode> 
? <text xsi:type="xsd:string" xmlns="">hello</text> 
? </Translate>
? </soapenv:Body>
? </soapenv:Envelope>

RECEIVE:

? <?xml version="1.0" encoding="utf-8" ?> 
- <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
- <soap:Body>
- <TranslateResponse xmlns="http://www.webservicex.net/">
? <TranslateResult><font color=red>Value cannot be null. Parameter name: translationmode</font></TranslateResult> 
? </TranslateResponse>
? </soap:Body>
? </soap:Envelope>

The invoke works when invoking using the Web Services explorer. The request is:

? <?xml version="1.0" encoding="UTF-8" ?> 
- <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:q0="http://www.webservicex.net/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <SOAP-ENV:Body>
- <q0:Translate>
? <q0:LanguageMode>EnglishTOFrench</q0:LanguageMode> 
? <q0:Text>hello</q0:Text> 
? </q0:Translate>
? </SOAP-ENV:Body>
? </SOAP-ENV:Envelope>

This occurs because the Web service expects the first letter of the elements to be uppercase. In this scenario, <languageMode> and <text> should actually be sent as <LanguageMode> and <Text>.
