Problem returning list of objects with jsr181/jaxb2 binding
-----------------------------------------------------------
Key: XFIRE-992
URL: http://jira.codehaus.org/browse/XFIRE-992
Project: XFire
Issue Type: Bug
Components: JAXB 2.0
Affects Versions: 1.2.6
Environment: Linux, Java 1.5
Reporter: Tim Morrow
Assignee: Dan Diephouse
I'm using XFire 1.2.6 and trying to return a list of objects from a service
method. I'm using jsr181 and jaxb2 annotations. I just can't seem to get it
to work. It seems like the XML produced by the server does not match the WSDL
(or at least, doesn't match what WSDL-generated clients expect).
I'm _pretty_ sure its not a namespace issue.
My service looks like this:
{code:title=MyService.java}
@SOAPBinding
@WebService(name = "MyServiceInterface", targetNamespace =
"http://ws.mycompany.com";)
public interface MyService
{
List<Thing> getThings();
List<String> getStrings();
}
{code}
{code:title=MyServiceImpl.java}
@WebService(serviceName = "MyService", endpointInterface =
"com.mycompany.MyService")
public class MyServiceImpl implements MyService
{
public List<String> getStrings()
{
return Collections.singletonList("the string");
}
public List<Thing> getThings()
{
return Collections.singletonList(new Thing("the thing"));
}
}
{code}
{code:title=Thing.java}
@XmlType(
name = "Thing",
namespace = "http://ws.mycompany.com/model";
)
public class Thing
{
private String name;
public Thing()
{
super();
}
public Thing(String name)
{
this.name = name;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
}
{code}
I do have a package-info.java in the same package as Thing.java with this:
{code:title=package-info.java}
@javax.xml.bind.annotation.XmlSchema(namespace =
"http://ws.mycompany.com/model";, elementFormDefault =
javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
{code}
The WSDL looks fine. Here is the schema section:
{code:xml}
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://ws.mycompany.com";>
<xsd:element name="getStrings">
<xsd:complexType />
</xsd:element>
<xsd:complexType name="ArrayOfString">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="string"
nillable="true" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
<xsd:element name="getStringsResponse">
<xsd:complexType>
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="1" name="out" nillable="true"
type="tns:ArrayOfString" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="getThings">
<xsd:complexType />
</xsd:element>
<xsd:element name="getThingsResponse">
<xsd:complexType>
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="1" name="out" nillable="true"
type="ns1:ArrayOfThing" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://ws.mycompany.com/model";>
<xsd:complexType name="ArrayOfThing">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="Thing"
nillable="true" type="ns1:Thing" />
</xsd:sequence>
</xsd:complexType>
<xs:complexType xmlns:xs="http://www.w3.org/2001/XMLSchema"; name="Thing">
<xs:sequence>
<xs:element minOccurs="0" name="name" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xsd:schema>
{code}
The content returned when invoking getThings is:
{code:xml}
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<soap:Body>
<getThingsResponse xmlns="http://ws.mycompany.com";>
<out xmlns="http://ws.mycompany.com";>
<ns2:out xmlns="http://ws.mycompany.com/model";
xmlns:ns2="http://ws.mycompany.com";>
<name>the thing</name>
</ns2:out>
</out>
</getThingsResponse>
</soap:Body>
</soap:Envelope>
{code}
With an XFire-generated JAXB client, it fails (silently!) to unmarshall the
XML. I also tried an Axis1 generated client, it failed with this message:
{{org.xml.sax.SAXException: Invalid element in
com.mycompany.ws.model.ArrayOfThing - out}}
My workaround is to not return {{List<Thing>}}, instead create my own container
class (i.e. manually create ArrayOfThing) and everything works fine.
