Question

I’m having difficulty getting XQuery to work. I downloaded Saxon-HE 9.2. It seems to only want to work with XSLT.

When I type:

java -jar saxon9he.jar

I get back usage information for XSLT. When I use the command syntax for XQuery, it doesn’t recognize the parameters (like -q), and gives XSLT usage information.

Here are some command line interactions:

>java -jar saxon9he.jar -q:"..\w3xQueryTut.xq"
Unknown option -q:..\w3xQueryTut.xq
Saxon-HE 9.2.0.6J from Saxonica
Usage: see http://www.saxonica.com/documentation/using-xsl/commandline.html
Options:
  -a                    Use xml-stylesheet PI, not -xsl argument

>java net.sf.saxon.Query -q:"..\w3xQueryTut.xq"
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/saxon/Query
Caused by: java.lang.ClassNotFoundException: net.sf.saxon.Query
                 // etc...
Could not find the main class: net.sf.saxon.Query.  Program will exit.

I’m probably making some stupid mistake. Do you know what it could be?

UPDATE 1 This command does not work:

>java -jar saxon9he.jar net.sf.saxon.Query q:"..\w3xQueryTut.xq"
Source file net.sf.saxon.Query does not exist

UPDATE 2 This command works better:

>dir

Answer 1

I don’t have problems with this command-line usage:

java -cp C:\xml\Parsers\Saxon\HE-9-2-0-6\saxon9he.jar net.sf.saxon.Query
-q:"C:\Program Files\Oxygen XML Editor 11\samples\xquery\Books\authors.xquery"
