Subject [jira] Commented: (CXF-2604) Issue with multiple REST methods having List<T> arguments
Date Fri, 08 Jan 2010 13:36:54 GMT


Alan Hazelton commented on CXF-2604:

Using an AegisElementProvider via Spring:

  <bean id="aegisProvider" class=""/>
  <jaxrs:server address="/v1/rest">
          <ref bean="helloworldWServiceBean"/>
	   <ref bean="customRequestHandlerProvider"/>
           <ref bean="customFormProvider"/>
	   <ref bean="aegisProvider"/>

I'll attach the provider but it is pretty much an empty class that extends AegisElementProvider
and calls the superclass methods in everything overridden.
I didn't add this part so I'm not sure why its there.

>          Issue Type: Bug
>          Components: Aegis Databinding, JAX-RS

>         Environment: JBoss 4.3 Using CXF 2.2.5

> I have a REST based service method that takes a List<Foo> parameter.  The method
is annotated with @POST and I can verify that the XML body of the POST request from the server
expects the top level element to be <ArrayOfFoo> and a second method that takes a List<Bar>
> It is important to note that the Foo and Bar classes are in different packages and therefore
the namespaces are different.
> The service would look something like this:
> My resource is defined like this:
> @Path("/")
> public class SomeResource {
>   @POST
>   @Path("/foo/update")
>   void postFoo(List<Foo> list) {}
>   @POST
>   @Path("/bar/update")
>   void postBar(List<Bar> list) {}
> } 
> When I stop the server in the debugger after posting to "/foo/update" I can see that
in the org.apache.cxf.aegis.type.TypeUtil class the getReadTypeStandalone() method is invoked
to get the top level type.  In this case it will be ArrayOfFoo and the type is located and
my method called with the correct list object un-marshalled from XML.
> In the second case, when posting to "/bar/update", ArrayOfBar is not found in the AegisContext
and null is returned by the getReadTypeStandalone method.
> The part that really confuses me is that if at runtime (after restarting the server)
I invoke the postBar method before invoking the postFoo method, the ArrayOfBar type is located
but not the ArrayOfFoo type.
> Some important things to note:
> 1.  This seems to only affect the ArrayOf<T> classes.   Other custom classes from
different namespaces are fine.
> 2.  This only happens when ArrayOfBar is in a different namespace from ArrayOfFoo.
