I created a doc/lit webservice as sessionbean endpoint!
I processed following steps:
1. I created the xsd-schema-files for the requests and responses
schema:
| ...
| <xs:element name="ReadRS">
| <xs:complexType>
| <xs:choice>
| <xs:sequence>
| <xs:element name="Success" type="SuccessType"/>
| </xs:sequence>
| <xs:element name="Errors" type="ErrorsType"/>
| </xs:choice>
| </xs:complexType>
| </xs:element>
| ...
2. I created the wsdl-file
3. wscompile with -f:documentliteral und -f:nodatabinding to create the SEI
SEI:
| ...
| public javax.xml.soap.SOAPElement ReadRQ(javax.xml.soap.SOAPElement rq)
| throws java.rmi.RemoteException;
| ...
4. xjc on the xsd-files to get the jaxb-databindings
5. create and deploy the bean on jboss (no errors)
Sessionbean (service endpoint):
import java.rmi.RemoteException;
|
| import javax.ejb.SessionBean;
| import javax.ejb.SessionContext;
| import javax.xml.bind.JAXBContext;
| import javax.xml.bind.Marshaller;
| import javax.xml.bind.Validator;
| import javax.xml.soap.SOAPElement;
| import javax.xml.soap.SOAPFactory;
| import javax.xml.transform.dom.DOMResult;
|
| import de.test.ws.vo.jaxb.ReadRS;
| import de.test.ws.vo.jaxb.ObjectFactory;
| .
| .
| .
|
| public SOAPElement ReadRQ(SOAPElement rq) throws RemoteException
| {
| SOAPElement response_ret = null;
|
| try
| {
| ObjectFactory objFactory = new ObjectFactory();
|
| JAXBContext jc = JAXBContext.newInstance("de.test.ws.vo.jaxb");
|
| .
| .
| .
|
| Marshaller m = jc.createMarshaller();
|
| ReadRS response = objFactory.createReadRS();
|
| response.setSuccess(...);
| .
| .
| .
|
| SOAPFactory factory = SOAPFactory.newInstance();
| SOAPElement parent = factory.createElement("dummy");
| // this produces the error
| m.marshal(response, new DOMResult(parent));
| // this produces the error
|
| response_ret = (SOAPElement) parent.getChildElements().next();
| }
| catch(Exception e)
| {
| e.printStackTrace();
| }
|
| return response_ret;
| }
The Problem:
Everthing works fine! The Sessionbean could unmarshall the Soapelement with
jaxb. Then I processed the Object and wanted to marshall the Object ->
Soapelement. This produced the following error:

- Is this a bug in the SoapFactoryImpl from Jboss (when I test the
jaxb-codesegment without jboss everything works fine)?
- Is there an other way to integrate jaxb-binding in jboss?
thanx Florian
