Hi,
We work with XFire version 1.2.4, with dynamic clients.
We have a service with a method like:
public Map<String, List<SomeBean>> test(List<String> stringList)
For the client to be able to serialize / deserialize correctly the parameters
and return values, we register the types:
- list of String
- SomeBean
- list of SomeBean
- map of String to List of SomeBean
----------------------
AegisBindingProvider bindingProvider = (AegisBindingProvider) client
.getService().getBindingProvider();
TypeMapping tm = bindingProvider.getTypeMappingRegistry()
.getDefaultTypeMapping();
Type someBeanType = new BeanType();
someBeanType.setTypeClass(SomeBean.class);
someBeanType.setSchemaType(new QName(namespace, name));
tm.register(someBeanType);
Type listOfStringType = new CollectionType(new StringType());
listOfStringType.setTypeClass(List.class);
listOfStringType.setSchemaType(new QName(namespace, name));
tm.register(listOfStringType);
Type listOfBeansType = new CollectionType(someBeanType);
listOfBeansType.setTypeClass(List.class);
listOfBeansType.setSchemaType(new QName(namespace, name));
tm.register(listOfBeansType);
but when we do:
List<String> param = new List<String>();
param.add("testing");
Map result = client.invoke("test", new Object[] {param});
we get:

After debuging with the XFire source code, we found that most likely our
problem originates form the fact the the TypeMappingRegistry holds the type
information in a hash map, having as key the class of the type. In our case,
this leads to the overwriting of the List<String> with the List<SomeBean>.
Is there a fix or a workaround for this?
Any help is really appreciated! Thank you!
Cheers,
Tudor
