Nick,
You can either copy the xmldb-api-***.jar file from cocoon-2.1.4 into cocoon-2.1.5, or download the eXist source and fix org.exist.xmldb.DatabaseImpl to include the following method:
public String[] getNames() {
return new String[] { dbName };
}I've done both.
You can access an xmldb resource through eXist either through the file generator or through the XQueryGenerator. For a file, you can just use
<map:generate src="xmldb:exist://host:port/db/col1/col2/col3/res.xml" />
For XQuery, see http://exist.sf.net/devguide.html.

Hi everybody,
I am trying to employ eXist via XML:DB. One of the requirements is to have eXist as a separate web application, so the option of integrating it into Cocoon is unavailable. As far as I understood it from available documentation for XMLDBTransformer and eXist, eXist driver has to be configured within cocoon.xconf for the XML:DB protocol.
I configure it as follows:
<><component-instance class="org.apache.cocoon.components.source.impl.XMLDBSourceFactory" name="xmldb">
<driver class="org.exist.xmldb.DatabaseImpl" type="exist"/>
</component-instance>
Then I copy the following eXist libraries to the WEB-INF/libs directory:
Catalina-util.jar
Exist.jar
Exist-optional.jar
Libreadline-java.jar
Xmldbc.jar
<>Xmlrpc-1.2.jar
This supposedly gets all the classes required. <>
However, when I try to access http://localhost:8080/cocoon-2.1.5/, I receive an error message:
HTTP Status 500 -

This is caused by the incompatibility of cocoon 2.1.5 libraries (2.1.4 works just fine).
<>Is there anybody who have already solved this problem and succeeded in accessing eXist through xmldb? If possible, can you also explain how to specify URI of the eXist database with xmldb?
Thank you very much in advance.
