[vbox-dev] Webservice connection under perl

thanks for pointing this out. It appears that SOAP::Lite has changed 
since the documentation was written.

 From your notes I gather that you ran stubmaker on the 
vboxwebService.wsdl file, not the vboxweb.wsdl file. As you're probably 
aware, the latter includes the former.

Now, stubmaker gets confused with namespaces when running it on the 
service file and injects "http://www.virtualbox.org/Service" into each 
method generated in the vboxService.pm when the namespace should be 
"http://www.virtualbox.org/" (without the "Service").

This is why the documentation says you should run stubmaker on 
vboxweb.wsdl, bypassing the service file, and avoiding the namespace 
confusion. At the time I didn't research the problem in detail since 
this workaround solved it for the time being.

It appears however that stubmaker now behaves differently. With 
SOAP::Lite 0.69 on Gentoo here, it no longer generates a vboxService.pm 
file, but a "FakeService.pm" file which doesn't work.

I have found the following workaround: run stubmaker on 
vboxwebService.wsdl and then, in the resulting vboxService.pm file, 
manually replace all occurences of "http://www.virtualbox.org/Service" 
with "http://www.virtualbox.org/". After that, the clienttest.pl runs 
fine -- except for one other problem with an API change, which is why I 
have attached a new version. This will be fixed in the next SDK release.

If there's somebody reading this who is aware of that we're doing 
something wrong with the namespaces in our WSDL files, we're open for 
feedback. But since all languages handle our files fine except for 
SOAP::Lite, I am suspecting that the problem lies not with us. I'm happy 
to fix the perl code and/or documentation so long as it doesn't break 
the other bindings.
