Consider the following WSDL:

<?xml version="1.0" encoding="UTF-8"?>
<definitions name='MySEIService' targetNamespace='http://javatype.mycompany.com' xmlns='http://schemas.xmlsoap.org/wsdl/' xmlns:ns1='http://other.com' xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' xmlns:tns='http://javatype.mycompany.com' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
<types>
<schema targetNamespace='http://other.com' xmlns='http://www.w3.org/2001/XMLSchema' xmlns:soap11-enc='http://schemas.xmlsoap.org/soap/encoding/' xmlns:tns='http://other.com' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
<complexType name='TestException'>
<sequence/>
</complexType>
<element name='TestException' type='tns:TestException'/>
</schema>
</types>
<message name='MySEI_testException'/>
<message name='MySEI_testExceptionResponse'/>
<message name='TestException'>
<part element='ns1:TestException' name='TestException'/>
</message>
<portType name='MySEI'>
<operation name='testException'>
<input message='tns:MySEI_testException'/>
<output message='tns:MySEI_testExceptionResponse'/>
<fault message='tns:TestException' name='TestException'/>
</operation>
</portType>
<binding name='MySEIBinding' type='tns:MySEI'>
<soap:binding style='rpc' transport='http://schemas.xmlsoap.org/soap/http'/>
<operation name='testException'>
<soap:operation soapAction=''/>
<input>
<soap:body namespace='http://javatype.mycompany.com' use='literal'/>
</input>
<output>
<soap:body namespace='http://javatype.mycompany.com' use='literal'/>
</output>
<fault name='TestException'>
<soap:fault name='TestException' use='literal'/>
</fault>
</operation>
</binding>
<service name='MySEIService'>
<port binding='tns:MySEIBinding' name='MySEIPort'>
<soap:address location='REPLACE_WITH_ACTUAL_URL'/>
</port>
</service>
</definitions>

Using the following wstools config:

<configuration xmlns="http://www.jboss.org/jbossws-tools">
<global>
<package-namespace package="com.other" namespace="http://other.com"/>
<package-namespace package="com.mycompany.javatype" namespace="http://javatype.mycompany.com"/>
</global>
<wsdl-java file="MySEIService.wsdl">
<mapping file="jaxrpc-mapping.xml" />
</wsdl-java>
</configuration>

The TestException class is not generated in the com.other package.
