Hi,
I developed a web service using Axis 1.3 final. Since I already had a
WSDL for the service interface, I decided to create the types using
XmlBeans 2.1.0. So I have a simple interface for the service:
public SearchResultDocument search( QueryDocument query );
I created a server-config.wsdd containing a definition for the service
and a tag for each xmlbean I have (although I think I need
only a mapping for SearchResultDocument and QueryDocument, do I?). When
I deploy the service and try accessing the wsdl
(http://localhost/axis/services/myService?wsdl) I receive a
NullPointerException thrown by XmlBeanSerializer:
AxisFault
faultCode:
{http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: java.lang.NullPointerException
faultActor:

...
Since I created the beans from WSDL, I expect Axis to generate an
equivalent WSDL using the XmlBeans themselves.
If I try to set a mapping using the concrete XmlBeans implementations
(SearchResultDocumentImpl), Axis doesn't seem to ever invoke
writeSchema() on the serializer, that is what I expect. I'm in doubt if
I really need a typemapping *also* for the concrete implementations
because I suspect that when from the service I return a SearchResultImpl
Axis can't find a serializer for that...
I tried to use the ser/deser provided at
http://issues.apache.org/jira/browse/AXIS-1764 with no luck. I found
problems integrating it with my actual installation, seems it cannot
find org.w3.x2001.xmlSchema.SchemaDocument$Schema... Since it looks like
importing a XmlBeans of the XSchema schema, I tried to create it but
then I had a ClassCastException
org.apache.xmlbeans.impl.xb.xsdschema.impl.Sc
hemaDocumentImpl$SchemaImpl at XmlBeanSerializer.java:151.
I'm a bit frustrated, so I didn't investigated the problem anymore...
Someone could help?
Bye,
Davide Romanini
