XPath evaluation of "/schema" results in empty target node

[Mickael Marrache]

Hi,

This is my XML schema (simplified) - schema.xsd:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns:srvcb="com:mycompany:myservice:base" 
xmlns="http://www.w3.org/2001/XMLSchema";
            targetNamespace="com:mycompany:myservice:base"
            elementFormDefault="qualified" xml:lang="EN">
<complexType name="MyType" abstract="true">
                        <sequence>
                                   <element name="a" type="string" />
                        </sequence>
            </complexType>
</schema>

The plugin declaration in the POM:

   <extraarg>-b</extraarg>

                                               </wadlOptions>

My bindings file:

<jxb:bindings version="2.1" xmlns="http://www.w3.org/2001/XMLSchema";
            xmlns:jxb="http://java.sun.com/xml/ns/jaxb"; 
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc";
            jxb:extensionBindingPrefixes="xjc" schemaLocation="schema.xsd" 
node="/schema">
            <jxb:globalBindings>
                        <xjc:simple />
            </jxb:globalBindings>
            <jxb:bindings
                        
node="//complexType[@name='MyType']/sequence/element[@name='a']">
                        <jxb:property name="b" />
            </jxb:bindings>
</jxb:bindings>

In my WADL, I import the schema as follows:

<?xml version="1.0"?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
            xsi:schemaLocation="http://wadl.dev.java.net/2009/02 
http://www.w3.org/Submission/wadl/wadl.xsd";
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns="http://wadl.dev.java.net/2009/02";
            xmlns:srvcb=" com:mycompany:myservice:base">

            <grammars>
                        <!-- <include href="schema.xsd" /> -->
                        <schema xmlns="http://www.w3.org/2001/XMLSchema"; 
xmlns:srvcr="com:mycompany:myservice:rest"
                                   
targetNamespace="com:mycompany:myservice:rest">
                                   <import 
namespace="com:mycompany:myservice:base"
                                               schemaLocation="schema.xsd" />
                        </schema>
            </grammars>

            .......
</application>

When I compile my project, I get the following exception:

Caused by: java.lang.RuntimeException: Error compiling schema from WADL : XPath 
evaluation of "/schema" results in empty target node
