ArchiveDataServer errors

[liushu <liushu@mail.ihep.ac.cn>]

Hello!
    I want to use Archive Data Server.My OS is linux redhat 9 with epics base 
3.14.7 and Channelarchive2.6.0.
    According to the manual.pdf.I create directory 
/var/www/html/archive/cgi,and copied 
ChannalArchiver/XMLRPCServer/O.linux-x86/ArchiveDataServer 
/var/www/cgi-bin/xmlrpc/ArchiveDataServer.cgi,and ChannalArchiver's example 
serverconfig.xml,serverconfig.dtd to /var/www/cgi-bin/xmlrpc/,and add 
following to httpd.conf:
   <Directory "/var/www/html/archive">
    Order Allow,Deny
    Allow from from All
</Directory>                                                                                
<Directory "/var/www/html/archive/cgi">
    SetEnv "EPICS_TS_MIN_WEST" "-480"
    SetEnv "LD_LIBRARY_PATH" 
"/usr/local/lib:/home/liushu/epicsinstall/base3.14.7/base/lib/linux-x86:/home/liushu/epicsinstall/base3.14.7/extensions/lib/linux-x86"
    SetEnv "SERVERCONFIG" "/var/www/cgi-bin/xmlrpc/serverconfig.xml"
    PerlHandler Apache::Registry
    PerlSendHeader On
    Options ExecCGI
</Directory>
   Then I restart httpd by   /etc/rc.d/init.d/httpd restart.I run 
ArchiveDataClient.pl -u 
http://192.168.20.155/cgi-bin/xmlrpc/ArchiveDataServer.cgi -i
  I got these output:
not well-formed (invalid token) at line 1, column 0, byte 0 at 
/usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi/XML/Parser.pm line 
185
  
   Is there anyone know what's wrong?
   And I have some questions:As I know that ArchiveEngine is web server too,so 
I want to know if I start ArchiveEngine I don't need to start httpd,right?And 
if I start httpd I don't need to start ArchiveEngine either,right?Or if I use 
ArchiveDataServer,which one I need,ArchiveEngine or httpd running?
   
   Thank you very much!

Best regards
Liushu
