Finally got around to attempt to make xindice / dbxml work with C2.
Checked the FAQ's and archive and ended up very confused.
Anyway I kind of summarised all the advice / postings I found and got it to
work [in the end].
Here is a rundown on what I did / modified to cocoon to get it to work.
The environment Win2K, Cocoon 2.0.1, Tomcat 4.0.1 and xindice-1.0rc1
Assumption: xindice is running on localhost:4080 and the addressbook example
db has been created.
There are apparently two ways of doing this:
1. using a generator
2. using a source-handler
In a recent posting it was noted however that the generator will be
deprecated shortly, so first I got rid of the bits in sitemap.xmap that deal
with the generator:
First comment out this section (it's near the top of sitemap.xmap)
<map:generator name="xmldb"
src="org.apache.cocoon.generation.XMLDBGenerator"
logger="sitemap.generator.xmldb">
<driver>org.dbxml.client.xmldb.DatabaseImpl</driver>
<base>xmldb:dbxml:///db/</base>
</map:generator>
<map:generator name="xmldbcollection"
src="org.apache.cocoon.generation.XMLDBCollectionGenerator"
logger="sitemap.generator.xmldbcollection">
<driver>org.dbxml.client.xmldb.DatabaseImpl</driver>
<base>xmldb:dbxml:///db/</base>
</map:generator>
Next comment out these lines (near the end of sitemap.xmap):
<map:match pattern="xmldb-generator/db/**/">
<map:generate type="xmldbcollection" src="/{1}"/>
<map:serialize type="xml"/>
</map:match>
<map:match pattern="xmldb-generator/db/**">
<map:generate type="xmldb" src="/{1}"/>
<map:serialize type="xml"/>
</map:match>
Now modify the remaining map:match entry:
<map:match pattern="xmldb/**">
<map:match type="request-parameter" pattern="xpath">
<map:generate src="xmldb:dbxml://localhost:4080/{../1}#{1}"/>
<map:serialize type="xml"/>
</map:match>
<map:generate src="xmldb:dbxml://localhost:4080/{1}"/>
<map:serialize type="xml"/>
</map:match>
so it looks like this:
<map:match pattern="xmldb/**">
<map:match type="request-parameter" pattern="xpath">
<map:generate src="xmldb:xindice://localhost:4080/db/{../1}#{1}"/>
<map:serialize type="xml"/>
</map:match>
<map:generate src="xmldb:xindice://localhost:4080/db/{1}"/>
<map:serialize type="xml"/>
</map:match>
Replace:
xmldb:dbxml://localhost:4080/
With:
xmldb:xindice://localhost:4080/db/
Untill I added the "db/" at the end I was getting an error saying a file
named:
XXXX_bootstrap.ior not found. Where XXXX is the collection name used in the
request. In fact if you look in %XINDICE_HOME%/docs there is only one .ior
file and it's called db_bootstrap.ior.
Next to cocoon.xconf. Modify the following lines:
<source-handler logger="core.source-handler">
<!-- xmldb pseudo protocol -->
<protocol name="xmldb"
class="org.apache.cocoon.components.source.XMLDBSourceFactory">
<!-- dbXML driver -->
<driver type="dbxml" class="org.dbxml.client.xmldb.DatabaseImpl"/>
<!-- Add here other XML:DB compliant databases drivers -->
</protocol>
</source-handler>
so they look like this:
<source-handler logger="core.source-handler">
<!-- xmldb pseudo protocol -->
<protocol name="xmldb"
class="org.apache.cocoon.components.source.XMLDBSourceFactory">
<!-- xindice driver -->
<driver type="xindice"
class="org.apache.xindice.client.xmldb.DatabaseImpl"/>
<!-- Add here other XML:DB compliant databases drivers -->
</protocol>
</source-handler>
Copy xindice.jar into the cocoon\WEB-INF\lib directory.
Start xindice, if it isn't running yet.
Start Tomcat.
And try: http://localhost:8080/cocoon/xmldb/addressbook/
The result looks something like this [I have three entries in the
addressbook db]:
<?xml version="1.0" encoding="UTF-8"?>
<collection:collections resources="3" collections="0"
xmlns:collection="http://apache.org/cocoon/xmldb/1.0";>
<collection:resource name="0100007f1f9fdabb000000ec2b2a4110"/>
<collection:resource name="0100007f1f9fdabb000000ec2b30c130"/>
<collection:resource name="0100007f1f9fdabb000000ec2b8cabd3"/>
</collection:collections>
To see all the entries in you addressbook db try:
http://localhost:8080/cocoon/xmldb/addressbook/?xpath=//person
Although all this is working sweet, I do get this error in error.log:
ERROR (2002-02-22) 13:51.08:468 [sitemap.generator.velocity]
(/cocoon/xmldb/addressbook/) HttpProcessor[82][4]/VelocityGenerator:
ResourceManager : unable to find resource 'VM_global_library.vm' in any
resource loader.
ERROR (2002-02-22) 13:51.08:578 [sitemap.generator.velocity]
(/cocoon/xmldb/addressbook/) HttpProcessor[82][4]/VelocityGenerator:
ResourceManager : unable to find resource 'VM_global_library.vm' in any
resource loader.
Always 2 entries like this but all seems to running fine.
I have written this in StyleBook format. You can download it from:
http://members.iinet.net.au/~xions/dev/xindice.zip
Unzip it to %PATH_TO_SERVLET_ENGINE%\webapps\cocoon\documentation\xdocs
Access it via:
