[Informa-developer] FW: informa serialization exception

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hello all,
	Following a suggestion from Mohd. Amin, I have written a Quartz
Job
To update rss feeds automatically using Quartz.
In doing that, I am receiving a huge exception when trying to load
channels,
Particularly when trying to get values from column locstring.

Unfortunately I forgot at home my channels.hbm.xml, but it looks like
troubles happen as long as I declare a mapping for column locstring.
I found same entry in this blog (dated last year), 

http://www.cheblogs.com/roller/page/princeamin/20040711?catname=Java

and I was wondering
If anyone knows anything about it, because this problem is a real
showstopper for me..
If I use the column 'site' to create a ChannelBuilder, I am not
receiving feeds at all

Anyone can help?

I have attached the job that I am using (I am using Spring together with
Quartz, I am getting Hibernate session from spring..... anyway error
happens
While Hibernate is trying to retrieve channels for the problem mentioned
above..)

Thanx in advance and regards
	Marco
