Hi,
I'm not sure it this is a known issue or not, but here's the problem I'm
having with the feeding (atom, rss) binding;
I use the FeedAggregator sample that is shipped with
tuscany-sca-0.91-incubating. It runs fine out-of-the-box. However if I
change the feed reference to point to a feed that is at a endpoint that has
URL parameters, it fails (see stacktrace below).
To reproduce: change the feed2 reference to something like this (which is
the feed from a confluence site):
<binding.atom uri="
http://mywiki/spaces/createrssfeed.action?types=page&types=blogpost&types=comment&spaces=&sort=modified&title=Dashboard+RSS+Feed&maxResults=15&publicFeed=false&os_authType=basic&rssType=atom"/

Thanks!
Good catch!
It looks like it's not an issue with the Feed binding, but a more
general issue with a URL containing "&" in an XML attribute. Could you
try to escape the "&" as "&"? like this:

Thanks
