Description

When CXF is publishing web services, the following exception occurs:

Caused by: java.lang.NullPointerException
        at org.apache.ws.commons.schema.utils.NamespaceMap.getNamespaceURI(NamespaceMap.java:47)
        at org.apache.ws.commons.schema.SchemaBuilder.getRefQName(SchemaBuilder.java:587)
        at org.apache.ws.commons.schema.SchemaBuilder.getRefQName(SchemaBuilder.java:566)
        at org.apache.ws.commons.schema.SchemaBuilder.handleElement(SchemaBuilder.java:1406)

If an XML prefix is used without being declared, that exception occurs.

In the following sample, the prefix is "pel" and it's correctly declared:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:pel="http://www.X.com/is/xml/core/model/thirdparty/personlight" 
xmlns:pol="http://www.X.com/is/xml/core/model/policy" xmlns:cov="http://www.X.com/is/xml/traditionallife/model/offer/coverage" 
xmlns:prd="http://www.X.com/is/xml/traditionallife/model/product" xmlns:ind="http://www.X.com/is/xml/core/model/indexation" 
targetNamespace="http://www.X.com/is/xml/traditionallife/model/policy" elementFormDefault="qualified">

Unfortunately, there is a space in one of the usage of "pel":

<xsd:element name="prospect" type=" pel:PersonLight" />

Removing the space before the prefix avoids to have the exception.

That bug is corrected in the newest version of Xml schema:

        <dependency>
            <groupId>org.apache.ws.commons.schema</groupId>
            <artifactId>XmlSchema</artifactId>
            <version>1.4.6</version>
        </dependency>

Path to the dependency:
[INFO] +- com.bsb.sf.integration:bsb-sf-cxf-core-integration:jar:ws-migration-1-SNAPSHOT:compile
[INFO] | +- org.apache.cxf:cxf-rt-frontend-jaxws:jar:2.2.6:compile
[INFO] | | +- org.apache.cxf:cxf-api:jar:2.2.6:compile

Note that XmlSchema 1.4.5 is still present in the latest release.
