Use Saxon Proccessor to Process XQuery (without external variables)

[Alice Wei]

Hi,

  Thanks for helping me out with solving this problem. The follow up 
question I have is, should I create a different command to parse the 
result when there is no external variable stated in my XQuery?

For example:

declare boundary-space preserve;

<course_name>
{
  let $course := doc("resume_2.xml")//course_name/name
return
<name>{string-join($course, ', ')}</name>
}
</course_name>

This one obviously has no external variables to be declared. When I use 
the terminal prompt to call up the command, the error brings up as the 
one below:

java -classpath ./saxon8.jar net.sf.Query question_1_1.xquery > query_1.xml
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/Query

Am I not supposed to run the XQuery command this way? The error does 
not generate as the one above when there is an "external variable" in 
the declare statement at the beginning?

Thanks to those who can help.

Alice
