Error importing function modules with eXist

Post by duck1123 » Sat Mar 04, 2006 7:27 pm

I have been testing out the new integration with an eXist db. I have done everything I'm supposed to, including compiling the latest version from CVS, and copying all of the relevant jars, and I am able to send XQuries to eXist and get the propper results back. (a little slowly maybe, but that just may be my computer.)

I am opening a XQuery from /db/kronk/mycyclopedia/ by using the Webdav interface. Everything works fine, until I try to open a query that references a *.xqm (XQuery Module) located in the same collection/folder.

My XQuery looks like this:
(: snip :)
import module namespace mycf="" at "functions.xqm";
(: snip :)

when I try to run or validate this query, I get the error:
SystemID: http://kronk@ ... irthday.xq
Description: error found while loading module mycf: source for module not found: cannot read module source from file at C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\exist\functions.xqm

shouldn't Oxygen try to load that file from: http://kronk@ ... ctions.xqm and not from the exist webapp directory in Tomcat? Is this a bug, or am I just doing something wrong. (The query works from within eXist)

The eXist server loads modules relative to its own context and we cannot change that from oXygen (that connects to the server remotely - through XML-RPC). You will get the same result running eXist Client Shell and using the Remote type to connect.

It is a good practice to not use relative paths for imported modules but use instead the following:

- if the module is in your database : xmldb:exist:///db/path/module.xq
- if the module is in your file system : file:///C:/path/module.xq
- if the module is available through http : http://server/path/module.xq.

In your case, the import will look like that:

import module namespace mycf="" at "xmldb:exist:///db/kronk/mycyclopedia/functions.xqm";
