Newbie question
Have just downloaded the CVS version of Xindice and Tomcat and am new
to both. So excuse my ignorance.
Steps I've take are:
* ant build - seems to have worked
* Completely failed to figure how to start it standalone, since the startup.bat
file seems to have gone - so investigated Tomcat
* Installed Tomcat 4.1.12
* copied Xindice.war to /wepapps dir. of Tomcat
* start Tomcat
I get the following exceptions on a start:
=====================
31-Oct-2002 17:33:17 org.apache.commons.digester.Digester error

at org.apache.crimson.parser.Parser2.error(Parser2.java:3160)
=====================
However, I also get a database started ok message:
31-Oct-2002 17:33:19 org.apache.xindice.server.XindiceServlet init
INFO: Database successfully started
And I can access the db via http://localhost:8080/xindice-1.1b
So it looks like the exception may not be critical
Anyone got any thoughts/suggestions?
TIA

Use ad hoc quotes :
xpath -c /db/publications/books -q "//Book[@InStock='yes']"
Mind that quotes can be different according to shells.

Re: Unable to query using xPath predicate

You'll find it is always safer to wrap the whole xpath query in quotes,
and then use single quotes in the predicates. This has solved lots of
problems for me as my shell also has issues with unquoted parentheses
such as: [contains(Book, 'foo')]
try: xpath -c /db/publications/books -q "//Book[@InStock='yes']"

Unable to query using xPath predicate
Posted by "Roger L. Costello" <co...@mitre.org>.
Hi Folks,
I have just started using XIndice. Please bear with me if my questions
are naive.
[1] I have stored in a collection the document BookCatalogue.xml.
Here's a sample of what the document looks like:
<?xml version="1.0"?>
<BookCatalogue>
<Book InStock="yes">
<Title>...</Title>
<Author>...</Author>
</Book>
...
</BookCatalogue>
Note the InStock attribute. I would like to issue this query: "Find all
books that are in-stock".
I believe that here is the appropriate XIndice query:
xpath -c /db/publications/books -q //Book[@InStock="yes"]
However, this results in no nodes being selected.
Am I doing something wrong? The documentation shows a query with a
predicate, but I have not been successful at getting queries with
predicates to work.
[2] I have found that simple XPath expressions without a predicate does
work. For example, this works:
xpath -c /db/publications/books -q //Book
However, it returns a series of XML documents (each document contains
one <Book>...</Book>), not a series of nodes (as the documentation
indicates). That is, the query returns:
<?xml version="1.0"?>
<Book ...>
...
</Book>
<?xml version="1.0"?>
<Book ...>
...
</Book>
etc
The documentation says that the results should be simply a series of
nodes:
<Book ...>
...
</Book>
<Book ...>
...
</Book>
etc
Again, am I doing something wrong?
[3] The documentation says that XUpdate may be used to update the
documents in the XIndice database. However, it provides no indication
of "how" to actually submit an XUpdate document. Is there a
command-line command for submitting an XUpdate document? Can someone
give me instructions on the mechanism for using XUpdate with XIndice?
[4] I noticed on the Web site "XIndice was last modified in 2000". Is
this technology progressing? Has work stopped on it?
Thanks! /Roger

<display-name>/<description> are in the wrong place. They should be one line up

Using win2k.
I think the split over two lines is just a cut and paste error of the exception
output on my part. It wasn't in the original file.
Could the web.xml DTD have changed to make the <display-name> and
<description> elements invalid in the latest tomcat release? Or maybe these
tags weren't in original DTD, but tomcat didn't validate/complain about them.

No leftovers, I've added these lines for 1.1. But it works fine by me
(never had problems).
I'm just curious to know why "display-name" it cut in two lines.
SEVERE: Parse Error at line 9 column -1: Element "servlet" does not allow
"displ
ay-name" here.
What is your operating system? (maybe has something to do with the
encoding of the file)

Great thanks - took both lines out and no exceptions. Anyone know whether
these "leftovers" from an old config, or are they needed when Xindice is
used in other configurations (e.g. standalone etc.)
