Hello!
Is this the correct email address to send Xindice questions to?
I am new to Xindice.  Is there any documentation on Xindice other than
what is up on the Apache website?  In particular, I am looking for
information on locking of data for updates, a way to do the equivalent of
an auto-increment field in a relational database and tips on how to best
structure the data in Xindice.  For example is it better to put each
"record" in its own file? 
Below is a problem I am having with XUpdate:

I am having difficulties with the XUpdateQueryService.  I am trying to
follow the examples in the developer's Guide at: 
 http://xml.apache.org/xindice/guide-developer.html 
I am trying to create an application modeled on the Addressbook sample
application but with a slightly different data structure where I have
multiple person "records" in one file rather than each person in a
different file like the Addressbook. In this case, it would be best if I
could just update one element rather that remove the document and rewrite
it with the updated data as in the Addressbook application. 
I am having trouble finding out about the format of the contents of the
String variable xupdate in the code fragment below:
XUpdateQueryService service = (XUpdateQueryService)
col.getService("XUpdateQueryService", "1.0");  
service.update(xupdate); 
I am unable to get to the reference for the examples at 
http://www.xmldb.org/xupdate
Any suggestions???

Here's the error message:

Send your questions to xindice-user list.

There are links to mail list archives on the site.

Depends; usually it's better to operate on multiple small XML documents 
in one collection, so this probably means that each "record" goes into 
its own "file".

It seems you are using Xindice 1.0 with CORBA API; it's currently not 
supported, and it is suggested to upgrade to the latest beta release. If 
you want to stick with 1.0, check mail list archives - may be somebody 
had similar problem.
