webserviceproxy working in snapshots?
I have tried several, including the latest, but there
seems to be a problem passing the remote site
information, and the examples always result in "Error
invoking remote service:
java.lang.IllegalArgumentException: host parameter is
null". The stack trace is below.
Does anyone have webserviceproxy working in a recent
dev snapshot?

Re: webserviceproxy working in snapshots?
Posted by AWR <ar...@yahoo.ca>.
OK, I got this working (thanks Art!). Since then, I
have been trying to figure out a way to use it with
any URL. This has come up before on the list:
"If you need to retrieve arbitrary html content it
would be safer to use HTMLGenerator, which can
retrieve remote sources via http, and runs the input
through Tidy before sending the sax events through the
pipeline, guaranteeing [?] that you get wellformed
xml." from
<http://www.mail-archive.com/cocoon-users@xml.apache.org/msg22307.html>.
Can a generator, like webserviceproxy, receive content
from another generator, in this case, HTMLGenerator?
