Hey Keith,
It's wonderful to get your expert advice.
Actually, the person who created my AMI did not implement port forwarding
in my image.
He checked the iptables and confirmed it.
There was an error on my part in the dspace config for SWORD module that was
carried over from my
early experimentation with bulk-submission using SWORD.
Thank you very much for the quick reply!

Debashree,
Nice to see a message from you.
I suspect that the person who created your AMI image placed an incorrect
entry into the Linux iptables. Entries were placed into the iptables to
implement port forwarding on incoming connections from standard port 80 to
Tomcat port 8080.
The most likely problem is that an entry was accidentally placed into the
iptables that also implements this forwarding on outgoing connections. This
is causing problems when the SWORD application tries to access the DTD at
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd.
Have your systems person check the Linux iptables entries and look to see if
anything is out of place. Please let me know of the resolution for this
issue.

Hi SWORD experts,
I have SWORD installed on my local machine. I built the sword.war file,
installed it under tomcat/webapps and am
able to view the servicedocument at localhost in the browser.
I then copied over the same sword.war file to my dspace instance on Amazon
Cloud. When I try to connect to it,
it fails with the error:
Server returned: org.purl.sword.client.SWORDClientExcpetion: Connection

Did not post the complete error file.will provide if it is needed. Have
highlighted the line that I believe is at the root of the connection
problem.
Please help!
