Re: [xfire-user] Interface containing a void return type

Thu, 04 May 2006 14:37:04 -0700 

Hiya,
This does seem to be some kind of issue with the dynamic client not regonizing the foo operation correctly. Can you file a jira again? 


BTW, I was talking with Sam Pullara on IRC yesterday and he had a good 
suggestion. It'd be really cool to hand the schemas to JAXB to compile 
on the fly, then use the JAXB objects. So that way if there is some 
complex type then we could do things like this without having the files 
around:


book = new Book();
book.name = "XFire for dummies"

bookClient.addBook(book);

Yes groovySOAP is based on the dynamic client so this is the one that is
used -)

I call the client doing this:
Object[] response =3D client.invoke(name, objs);
and I have checked that name is "foo" and objs is an array of 2 elements.

It looks like the second argument is ignored. There was a JIRA  issue for
this a while ago but it is closed and I checked it is working on my sample
doing a sum of 2 integers...


Changing the interface in such a way that the method returns a STring 
works

nicely. Here is the conversation:

So this has really to do with the dynamic client.
