[MOBY-dev] problems with retrieveService() in Perl API

[Frank Gibbons]

Hi,

Just wondering if anyone has had problems with the Perl API. As you know, 
I've been having difficulties the last few days. My current roadblock is 
that, while I can discover services from MOBY Central, I am unable to 
retrieve the service description (WSDL). I have tried Mark's at iCapture, 
as well as the one at MIPS, and the symptoms are identical at both.

Retrieval fails because the MOBY Central thinks it got an empty message 
from me, and XML parser *hates* being asked to parse empty messages. Yet, 
if I insert code immediately preceding the line in which I call the remote 
MOBY Central, I can verify that I'm *not* sending an empty message.

So now I'm wondering whether there could some problem with the transport 
layer, or possibly with some kind of dependency on a module that no-one is 
aware of. Has anyone run into this kind of issue before? I don't understand 
what's going on: I installed a new perl interpreter to deal with some 
issues I was having parsing XML, and now I can't even get the XML I was 
having difficulty with! Any ideas would be most welcome.

Thanks.
