Hi Kay, 

Thank you for your suggestion - it worked. 

We have one more question. right now by doing:

 [sysuser@sc XMLRPCServer]$ ./ArchiveDataClient.pl -u
http://sc.starp.bnl.gov/archive/cgi/ArchiveDataServer.cgi -k 1 -l
Channels:
Channel BoolPV, 03/05/2004 18:53:56.767577600 - 03/05/2004
18:58:51.901960000
Channel DTL_HPRF:Tnk1:T, 03/01/2004 17:28:00.035262000 - 03/29/2004
13:01:00.230310000
Channel DTL_HPRF:Tnk2:T, 03/01/2004 17:28:00.035262000 - 03/29/2004
13:00:00.031041000
Channel DTL_HPRF:Tnk3:T, 03/01/2004 17:27:59.985282000 - 03/29/2004
13:01:00.280299000
... 

we do see all channels inside index file but once we try to run it with
ArchiveViewer and plot it gives the error message :

 java.lang.Exception: Couldn't execute the archiver.values request
java.io.IOException: org.xml.sax.SAXParseException: expected Element

and in console: Fatal error parsing XML: org.xml.sax.SAXParseException:
expected Element

Any idea? 

Bill && Yura 

Thanks

Hi:

Well, I assume that
'/home/sysuser/epics/extensions/src/ChannelArchiver/DemoData/index'
is actually an existing path & filename that you configured.

The error message indicates that your web server &
ArchiveDataServer are also OK, otherwise
you'd never get as far as that error message.

The web server runs your copy of the network data server
as "nobody" or a similar low-privilege user.
So the next thing to check would be that
/home/sysuser/epics/extensions/src/ChannelArchiver/DemoData/*
and all the directories in the path to ... DemoData
have 'r-x' access for "nobody" or whoever's configured
in your web server to run CGI code.
