How to register SerializerFactory and DeSerializerFactory fo

[czhao07]

I am implementing a WS client with JBossWS to access a third-party web service, one of the service operations takes a xsd:anyType type as the parameter, and it gets mapped to SOAPElement in the wstools generated code. When I invoke the service, I got this exception:

javax.xml.rpc.JAXRPCException: Cannot obtain serializer factory for: [xmlType={http://www.w3.org/2001/XMLSchema}anyType,javaType=interface javax.xml.soap.SOAPElement]

This article (http://wiki.jboss.org/wiki/Wiki.jsp?page=WS4EETypeMapping) talks about how to add type mappings for service endpoint, not the WS client. But anyway, I tried to add file ws4ee-deployment.xml to my client's META-INF folder with following mapping:

<typeMapping qname="xsd:anyType"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
serializer="org.jboss.ws.jaxrpc.encoding.ElementSerializerFactory" deserializer="org.jboss.ws.jaxrpc.encoding.ElementDeserializerFactory"
type="java:javax.xml.soap.SOAPElement"
encodingStyle="" />

and it didn't work.

Does anyone know a solution to this issue?

Much thanks!

What version of JBossWS are you using? ws4ee-deployment.xml was only valid on jboss-ws4ee which was the older axis based stack.

I am using JBossWS 1.0.3.GA.

[jason.greene]

I believe this was fixed in 1.0.4. Although you can work around the issue by changing your mapping file and code to use a org.w3c.dom.Element instead.

I just upgrade JBossWS to 1.0.4, but still have the same problem:

javax.xml.rpc.JAXRPCException: Cannot obtain serializer factory for: [xmlType={http://www.w3.org/2001/XMLSchema}anyType,javaType=interface javax.xml.soap.SOAPElement]
at org.jboss.ws.soap.SOAPContentElement.getSerializerFactory(SOAPContentElement.java:377)
at org.jboss.ws.soap.SOAPContentElement.getXMLFragment(SOAPContentElement.java:143)
at org.jboss.ws.soap.SOAPContentElement.expandToDOM(SOAPContentElement.java:802)

I think I found the problem. The web service I need to call uses soap encoding style (http://schemas.xmlsoap.org/soap/encoding/), hence EncodedTypeMapping is used which registers type mapping for xsd:anyType as this:

// register mapping for xsd:anyType
registerInternal(SOAPElement.class, Constants.TYPE_SOAP11_ANYTYPE, new SOAPElementSerializerFactory(), new SOAPElementDeserializerFactory());
registerInternal(Element.class, Constants.TYPE_SOAP11_ANYTYPE, new ElementSerializerFactory(), new ElementDeserializerFactory());

In above code, it registers (De)SerializerFactory for a wrong QName. While the fix in LiteralTypeMapping is correct:

// register mapping for xsd:anyType
registerInternal(SOAPElement.class, Constants.TYPE_LITERAL_ANYTYPE, new SOAPElementSerializerFactory(), new SOAPElementDeserializerFactory());
registerInternal(Element.class, Constants.TYPE_LITERAL_ANYTYPE, new ElementSerializerFactory(), new ElementDeserializerFactory());

So I think the above lines of code should be moved to TypeMappingImpl.registerStandardLiteralTypes() in order to fix the problem with both literal and soap encoding styles.

[thomas.diesler]

The LiteralTypeMapping is constructed like this

 public LiteralTypeMapping()
 {
 ...

 registerStandardLiteralTypes();

 ...

 // register mapping for xsd:anyType
 register(SOAPElement.class, Constants.TYPE_LITERAL_ANYTYPE, new SOAPElementSerializerFactory(), new SOAPElementDeserializerFactory());
 register(Element.class, Constants.TYPE_LITERAL_ANYTYPE, new ElementSerializerFactory(), new ElementDeserializerFactory());
 }

Unfortunatly, it is not commented why xsd:antType is not considered as a standard literal type. Maybe only because it is not by the spec.

I hesitate to have this changed since in favour of rpc/encoded because it might break anyType handling for literal users.

However, lets have a jira for it

http://jira.jboss.org/jira/browse/JBWS-1595

[thomas.diesler]

This change might work for you

 public EncodedTypeMapping()
 {
 registerStandardLiteralTypes();
 registerStandardSOAP11EncodedTypes();

 // register mapping for xsd:anyType
 register(SOAPElement.class, Constants.TYPE_LITERAL_ANYTYPE, new SOAPElementSerializerFactory(), new SOAPElementDeserializerFactory());
 register(Element.class, Constants.TYPE_LITERAL_ANYTYPE, new ElementSerializerFactory(), new ElementDeserializerFactory());

 // register mapping for soap11-enc:anyType
 register(SOAPElement.class, Constants.TYPE_SOAP11_ANYTYPE, new SOAPElementSerializerFactory(), new SOAPElementDeserializerFactory());
 register(Element.class, Constants.TYPE_SOAP11_ANYTYPE, new ElementSerializerFactory(), new ElementDeserializerFactory());
 }

Yep, this should work. My workaround is to change the WSDL to not use soap encoding style, now it works just fine.
