Lion podcast producer can't publish to Lion apple wiki

Question

Hi,Buddies, We're using Podcast Producer on Lion to publish podcast to Lion wiki, use lion podcast composer to define publish to lion wiki/blog server and deploy workflow to PCP server successfully, When we used lion podcast capture to send podcast to pcp server, checked in xgrid agent log and it always stopped at following and say 404 not found with http error, also I found url for posting to wiki is still old architecture of snow leopard, the lion wiki or blog url should be like this http://wiki.edu/wiki/projects/test or http://wiki.edu/wiki/people/U0K4j3h/blog, it's odd! Lion PCP,lion composer, lion wiki, but pcp can't publish to lion wiki, Do you guys have any same experience of this issue? Thanks

I thought I would post back with the solution I finally found in case someone else runs across this. I was going crazy!
This link and the comments in reply to the topic show what the problem is. I could not find it in any Apple documentation so I'm very grateful to those who posted at this link, "Mounting a shared file system for Xgrid":

Basically, Xgrid agents don't have permission to access folders pointed to under /Volumes. The solution is to provide the complete network path in your workflow, starting with /Network/Servers/<servername>/<path to folder>.
As long as the Podcast Producer Xgrid user (in my case, "pcastxgrid") has permission to the directory exported and once the full path is in your workflow the agents can publish to the folder. Again, thanks to those who posted to the hints at macworld.
