Hi Peter

Assuming you are using a relatively new version of exist (either the snapshot or current subversion checkout) and you only want direct access (no XML-RPC or other fancy network stuff)

Here is what you have to do:

Copy the following jars to cocoons WEB-INF/lib directory:

exist/exist.jar

exist/exist-optional.jar

exist/lib/core/antlr.jar

exist/lib/core/commons-pool-1.2.jar

exist/lib/core/xmldb.jar

exist/lib/core/xmlrpc-1.2-patched.jar

Add the following to the Generators section of the sitemap:

<map:generator name="xquery" src=" org.exist.cocoon.XQueryGenerator "/>

Add the following to your cocoon.xconf: inside the the org.apache.cocoon.components.source.impl.XMLDBSourceFactory configuration (there should be a xindice driver configured)

I would recommend removing the unused driver, because I remember cocoon trying to initialize the driver, but because of a missing Xindice cocoon gets an error and skips the following drivers.

This should result in the xmldb:exist pseudo protocol being accessible.

To start the server, add the following to the cocoon.xconf:

Well I have to admit, that I created my own Server component for starting the db itself inside cocoon … think you will have to have a look for code looking like:

BrokerPool.configure(“exist”, minBrokers, maxBrokers, config);

This is where initializing the BorkerPool for the instance is initialted. Couldn’t fin exactly which class is needed for this.

If you don’t manage to find it, I can send you mine, but that is made for initializing multiple Database Instances automatically (one per virtual hosts) but It would be suitable for a start J

Last not least, you have to place the exist config.file in the WEB-INF/classes directory, so it can be found by the Configuration … think you can place it in WEB-INF/ directly, but I always use the classpath access path.

Hope this helps you and I didn’t miss anything (not using the original DB server and Drivers anymore)

Regards,

Chris

Betreff: eXist xmldb

Hi

I am trying to install the eXist xmldb into cocoon 2.1.9 running under tomcat 5.5, please:

1. Where can I find the best documentation on how to install eXist xmldb into cocoon. There are several such docs on the web but all the ones I have found are old and they mention eXist jars which are not in the latest eXist distribution.

2. Where can I find documentation on the "xmldb:// pseudo-protocol" other than the apidocs and hoe to use it

Thanks

Peter Sparkes
