Cocoon 2.2 + eXist native xml db 1.2.6

[Tomek Piechowicz]

Hi.
I`m new to Cocoon and I want to use this framework with eXist xml db
which is installed locally. In section 3. Cocoon Sitemap Configuration
on eXist home page (http://demo.exist-db.org/exist/configuration.xml) I
found some information about defining XML:DB driver as a pseudo-protocol
in Cocoon`s configuration file :

In eXist, pseudo-protocols are configured in Cocoon's main configuration
file WEB-INF/cocoon.xconf. To make use of these protocols, simply
specify the correct database driver class, as in the following example:

<source-handler logger="core.source-handler">
      <protocol
class="org.apache.cocoon.components.source.XMLDBSourceFactory"
      name="xmldb">
      <driver class="org.exist.xmldb.DatabaseImpl" type="exist"/>
      </protocol>
 </source-handler>

I don`t have cocoon.xconf in WEB-INF directory, so I don`t know where
should I put this code. I read that there is no global cocoon.xconf in
Cocoon 2.2 because each block has it`s own configuration file.

Could you give me some advice how to configure Cocoon to work with eXist ?

Regards,
Tomek

Ps: Sorry for poor english.

I went through archive in both Cocoon and eXist mailing lists and I found some useful informations.

1. After I created new cocoon 2.2 block in maven I copied following jars to WEB-INF/lib directory :

exist/exist.jar
exist/exist-optional.jar
exist/lib/core/antlr-2.7.6.jar
exist/lib/core/commons-pool-1.4.jar
exist/lib/core/xmldb.jar
exist/lib/core/xmlrpc-client-3.1.1.jar
exist/lib/core/xmlrpc-common.3.1.1.jar

      </protocol>
 </source-handler>

2. I`ve created my own cocoon.xconf in META-INF/cocoon/avalon/ and I put above code into it. After I run maven jetty

server threw exception :

org.apache.avalon.framework.configuration.ConfigurationException: Unknow document 'source-handler'

3. Then I tried another code which I`ve found somewhere in the archive :

<components>
        <source-factories>            
                <component-instance class="org.apache.cocoon.components.source.impl.XMLDBSourceFactory" name="xmldb">
                        <driver class="org.exist.xmldb.DatabaseImpl" type="exist"/>
                </component-instance>
        </source-factories>
</components>

but again server threw exception :

java.lang.ClassNotFoundException: org.apache.cocoon.components.source.impl.XMLDBSourceFactory


Can anyone help me with configuring cocoon to use XQueryGenerator to access eXist ?
