PullPoint: GetMessages(int maxNumber)
Hi,
the Web Services Base Notification 1.3 (WS-BaseNotification) Committee
Specification, 31 July 2006, declares the format of GetMessages request:
<wsnt:GetMessages>
<wsnt:MaximumNumber>xsd:nonNegativeInteger</wsnt:MaximumNumber> ?
{any} *
</wsnt:GetMessages>
Muse 2.0.0 and Muse 2.2.0 release the PullPoint interface is following:
/**
*
* @see PullPointDataStore#getMessages(int)
*
*/
NotificationMessage[] getMessages(int maxNumber)
throws UnableToGetMessagesFault;
The {any} element is not present in the method signature. Why?
Thanks
Luigi

This would complicate the routing code quite a bit, as instead of using
just the Java method signature and SOAP message for parsing/routing, we'd
need to go back and look at the resource's WSDL as well, and see if it had
an xsd:any at the end of the given operation, copy the last N parameters
into a dummy DOM Element, and make the call. We'd also need logic to
determine if a SOAP message had N parameters that fit the foo(param1,
param2, ..., paramN) model or if the last one was part of an xsd:any and
needed to be 'wrapped'. In all, I fear it would be rather shaky and hard to
debug.
A better solution might be this: the default implementation class
(SimplePullPoint) doesn't do anything with the data that might be in that
xsd:any slot, so presumably you're already writing your own class to handle
extra parameters. I suggest writing an implementation of the PullPoint
interface that simply forwards to an instance of SimplePullPoint, doing
whatever additional processing you need before/after. Using encapsulation
instead of inheritance will help you avoid the problem of having two
getMessages() methods in your PullPoint interface.

Yes, it is right.

This is true of a few other WS-* operations. The main reason is that Muse
invokes your Java code by using the WS-A Action to find the right Java
method; it then uses the number/type of parameters in the Java method to
determine how it should deserialize the SOAP body. Without this system, we
would have to use some kind of mapping/binding file, like in JAX-RPC, and
we still would not have variable parameters (because Java 1.4.x doesn't).
I think what you want is for Muse to recognize when an operation has an
xsd:any and then lump any remaining parameter elements under one Element,
so we can invoke a method like getMessages(int, Element). This is the only
way I can see this working given that Java 1.4.x doesn't have variable
args. Is this right?

This is true of a few other WS-* operations. The main reason is that Muse
invokes your Java code by using the WS-A Action to find the right Java
method; it then uses the number/type of parameters in the Java method to
determine how it should deserialize the SOAP body. Without this system, we
would have to use some kind of mapping/binding file, like in JAX-RPC, and
we still would not have variable parameters (because Java 1.4.x doesn't).
I think what you want is for Muse to recognize when an operation has an
xsd:any and then lump any remaining parameter elements under one Element,
so we can invoke a method like getMessages(int, Element). This is the only
way I can see this working given that Java 1.4.x doesn't have variable
args. Is this right?
