[MOBY-dev] MOBY Central now breaks Java

Thu Dec 16 19:23:54 UTC 2004

Hi everyone,

    MOBY Central code seems to have broken CentralImpl.java.  The 
returned object after a findService call is not well-formed XML, so Axis 
doesn't let you get very far with debugging.  I telneted to port 80 on 
MOBY Central and POSTed a hand-crafted findService request.  You can see 
the input and output below, but the gist of it is that the Perl parser 
of the MOBY Central server seems to switch a string for a hash reference 
somewhere internally while handling the SOAP payload.  I think this is a 
bug in the server-side Perl. Are these errors due to the server code 
transition currently taking place?

A second issue is that the MOBY Central Apache appends its 500 Error 
page to the SOAP message, making it an invalid XML document.  Therefore 
the real error never propagates to the client, but rather a parsing 
error ooccurs.

Regards,

Paul
