Session bean as web service using JAXB

Question

Hi all,
can anybody answer my question:
I have created java classes from XSD files using JDeveloper JAXB compilation. Is it possible to use these classes as parameters for webservice created as ejb3 session bean?
I'have tried but got this error when invoked web service method:
<env:Body>
<env:Fault>
<faultcode>env:Client</faultcode>
<faultstring>Caught exception while handling request: deserialization error: java.lang.NullPointerException</faultstring>
</env:Fault>
</env:Body>
</env:Envelope>
thanks,
Aigars

Hi Torstein,
<i>Seems to me that the problem is related to the msg sent to AE:
"HTTP response contains status code 401 with the description Unauthorized XML tag Envelope missing in SOAP message header (SAP XI Extension)"
</i>
According to you, the problem occurs within the SOAP envelope. Does your incoming SOAP message looks like the one below here?
If that's not the case, then make sure your SOAP/Web Service client is sending a valid SOAP envelope/request (like the sample below) to XI.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!--  Inbound Message -->
<SOAP:Envelope xmlns:SOAP='http://schemas.xmlsoap.org/soap/envelope/'>
<SOAP:Header/>
<SOAP:Body>
<ns1:WebServiceRequest xmlns:ns1='http://company.com/xi/webservice/myws' SOAP:actor='http://schemas.xmlsoap.org/soap/encoding/' xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
<Customer xsi:type='xsd:string'>000025</Customer>
<CompanyCode xsi:type='xsd:string'>BE01</CompanyCode>
<KeyDate xsi:type='xsd:string'>20050310</KeyDate>
<Selection>
<OpenItems xsi:type='xsd:string'>X</OpenItems>
<ClearItems xsi:type='xsd:string'></ClearItems>
<GLItems xsi:type='xsd:string'></GLItems>
<Dunning>
<From xsi:type='xsd:string'>A</From>
<To xsi:type='xsd:string'>Z</To>
</Dunning>
</Selection>
</ns1:WebServiceRequest>
</SOAP:Body>
</SOAP:Envelope>
Cheers,
