I try to define some common types to be used in multiple WSLDs into a xsd file WorkPackageServiceTypes.xsd as follows:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.example.org/Common/WorkPackageServiceTypes"
xmlns:tns="http://www.example.org/Common/WorkPackageServiceTypes"
elementFormDefault="qualified">

<complexType name="WorkPackageType">
<sequence>
<element name="WpRunningNo" type="long"
maxOccurs="1" minOccurs="1">
</element>
<element name="StartDate" type="dateTime"
maxOccurs="1" minOccurs="1">
</element>
<element name="EndDate" type="dateTime"
maxOccurs="1" minOccurs="1"></element>
<element name="Approved" type="boolean"
maxOccurs="1" minOccurs="1">
</element>
<element name="Enabled" type="boolean" maxOccurs="1"
minOccurs="1">
</element>
<element name="Terminated" type="boolean"
maxOccurs="1" minOccurs="1">
</element>
</sequence>
</complexType>
</schema>

I import this XSD into the WSDL of a service.

Both WSDL and XSD are located into the same folder (META-INF/wsdl/). wsconsume as generated all classes and stubs as expected. The web service is implemented as stateless session bean. If I package the ejb jar into an ear and deploy it to JBoss AS the following exception occurs during deployment:

If I deploy the jar directly without packaging into an ear it works.
