if you use xindice just for cocoon , you sould use the Xindice embed mode ( so delete the war , you don't need a separate servlet to use the database)
with this mode , you  don't use the network protocole XML-RPC, so it's faster.
in the cocoon.xconf
search this lines..
    <component-instance class="org.apache.cocoon.components.source.impl.XMLDBSourceFactory" name="xmldb">
            <driver class="org.apache.xindice.client.xmldb.DatabaseImpl" type="xindice"/>
-->> add this line       <driver class="org.apache.xindice.client.xmldb.embed.DatabaseImpl" type="xindice"/>
for the location of the db
see http://marc.theaimsgroup.com/?l=xindice-users&m=105845229126670&w=2
in complement,  modiy the catalina.sh(or bat) to add  -Dxindice.configuration option
in the sitemap :
 - to read/seach 
use this example :
   <map:match pattern="xmldb/**">
        <map:match type="request-parameter" pattern="xpath">
             <map:generate src="xmldb:xindice-embed:///db/{../1}#{1}"/>
             <map:serialize type="xml"/>
example :  http://localhost:8080/cocoon/xmldb/mycollection/mysubcollection/?xpath=myXpathquery 
- to write in the database
use the xmldb transformer
in the declaration tranformer
 <map:transformer name="xmldb" src="org.apache.cocoon.transformation.XMLDBTransformer">
see the xmldb block in cocoon for more informations about this transformer

Subject: xindice 1.1b2 + cocoon 2.1 + tomcat 4.1.27 + winxp - HOW??

i'm totally new to xindice and I'm trying to set it up together with my cocoon installation.
cocoon is installed correctly and worked. I downloaded xindice successfully from CVS, built the *.war and deployed it. when I start tomcat I get the message "INFO: Database successfuly started" - so i guess xindice is running as expected. I can also read the "UGLY DEBUG TOOL" thing and browser the database.
now, for being able to work with it, i would like to install the command line tool. however, i haven't found any useful (or detailed enough) information on how to install it on win xp.
I did everything explained at http://nagoya.apache.org/wiki/apachewiki.cgi?HowToXindice1o1bCocoon2 (the "Installing the Xindice command line tool" part).
I have a separate xindice folder outside of the webapps, (set to %XINDICE_HOME%), added %XINDICE_HOME%/bin to the %PATH% variable ... well. that's it.
if I only have bin/* , dist/*, java/lib/* and config*/ folders in there (as suggested) the "xindice" command doesn't work at all. If I copy the build folder in as well it at least gives me two action options: "start" and "debug".
but how do i tell the xindice command line tool in the external %XINDICE_HOME% folder to use the database in %TOMCAT_HOME%/webapps/xindice-1.1b2/WEB_INF/db ?? the given command there doesn't work - most likely since it's explained for linux.
well, sorry if that's newbie stuff ;) if i got anything wrong please correct me. any help is very much appreciated!!
thanx guys
