Jack TanSubject: XQUERY Java run-time error
Author: Jack Tan
Date: 16 Apr 2007 06:21 PM
XQUERY runs correctly under Stylus studio.

After compilation and configuring Path variable it compiles but fails to execute. WHAT CAN CAUSE THE FAILURE? I am using Stylus Studion 2006 Enterprise Edition.

Does it has something to tdo with resolving URI (relative?...)?

(Fatal Error) net.sf.saxon.trans.DynamicError: Invalid relative URI {C:\SoftwareDevelopment\LVS_Wor...}: Invalid relative URI {C:\SoftwareDevelopment\LVS_Wor...}: Illegal character in opaque part at index 2: <<< WHAT THIS MEANS???? C:\SoftwareDevelopment\LVS_Workspace\tool_m2c2\doc\graphs\rf_headers.xml
Exception in thread "main" net.sf.saxon.trans.DynamicError: net.sf.saxon.trans.DynamicError: Invalid relative URI {C:\SoftwareDevelopment\LVS_Wor...}
at net.sf.saxon.functions.Document.makeDoc(Document.java:252)
at net.sf.saxon.functions.Doc.doc(Doc.java:87)

Here are the supporting printouts:

file:///c:/SoftwareDevelopment/LVS_Workspace/tool_m2c2/doc/graphs/rf_generator.xquery:14,-1: (Fatal Error) Invalid relative URI {C:\SoftwareDevelopment\LVS_Wor...}: Illegal character in opaque part at index 2: C:\SoftwareDevelopment\LVS_Workspace\tool_m2c2\doc\graphs\rf_headers.xml

where the rf_headers.xml:

<?xml version="1.0"?>
<msgs xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="rf_frame.xsd">
<rf name="RF_MSG_STD">
<field name="sync1">UINT8</field>
<field name="sync2">UINT8</field>

here is the schema "rf_frame.xsd":
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="msgs">

You need to show us how you access rf_headers.xml from xquery

are you using the doc function?

how do you format the URL?

Are you using the Java code generated by Stylus Studio?

could you post the Java code?

thanks for late night reply ;-)

I am using Java generated code.

Interestingly when in the XQUERY script I changed:

let $svgDoc := "\SoftwareDevelopment\LVS_Workspace\tool\doc\graphs\rf_headers.xml"
let $doc := "C:\SoftwareDevelopment\LVS_Workspace\tool\doc\graphs\intermediate.xml"


let $svgDoc := "rf_headers.xml"
let $doc := "C:\SoftwareDevelopment\LVS_Workspace\tool\doc\graphs\intermediate.xml"

problem disapeared.

Below, I am attaching Java code.

The problem is indeed most likely an invalid relative URI.

Just having a pathname starting with a backslash doesn't
help, because it's not a valid relative URI. When converting
from filesnames to URI's, Saxon will attempt to open using
the java URI handling, but since there is an absolute path (you
started it with a \) but no protocol, it won't open. If it
prepends "file:///" it gets an invalid URI. Same thing if it
tries to open as a file.

Either include the C: to make it an absolute name, or make it a
true URI by including the protocol.
