Javax.servlet.ServletException: The name "" is not legal for JDOM/XML namespaces

Question

Dear all,
First of all sorry, if this is not the right place for my question.
I am facing some problem with the XFire Webservices. When i am trying to access the WSDL through the url. server is throwing the following exception :
javax.servlet.ServletException: The name "" is not legal for JDOM/XML namespaces: Namespace URIs must be non-null and non-empty Strings.
     org.codehaus.xfire.transport.http.XFireServletController.doService(XFireServletController.java:143)
     org.codehaus.xfire.transport.http.XFireServlet.doGet(XFireServlet.java:107)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
     org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

cont.......
I am not able to figure out the root cause for this. The service.xml file looks like below:
<?xml version="1.0" encoding="UTF-8"?>
<!-- START Service.xml -->
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<!-- Construct the castor service factory by Spring -->
<bean id="castorTypeRegistry" class="org.codehaus.xfire.castor.CastorTypeMappingRegistry"/>
<bean id="bindingProvider" class="org.codehaus.xfire.aegis.AegisBindingProvider">
<constructor-arg ref="castorTypeRegistry"/>
</bean>
<bean id="castorServiceFactory" class="org.codehaus.xfire.service.binding.ObjectServiceFactory">
<constructor-arg index="0" ref="xfire.transportManager"/>
<constructor-arg index="1" ref="bindingProvider"/>
</bean>
<service>
<name>ReleaseManager</name>
<namespace>ReleaseManager</namespace>
<serviceClass>com.pinkroccade.jfoundation.calculation.releases.ReleaseManager</serviceClass>
<implementationClass>com.pinkroccade.jfoundation.calculation.releases.ReleaseManagerImpl</implementationClass>
<schemas>
<schema>META-INF/schema/release-impact-worksheet-3.2.0.xsd</schema>
</schemas>
<style>document</style>
<serviceFactory>#castorServiceFactory</serviceFactory>
</service>
</beans>
<!-- END Service.xml-->
The issue which i am facing is it due to the problem with the service.xml (Which i dont think so..), Or is it any thing to do with the XSD file which i am using.
Can any body give me some guide lines for this ????
Thanks in advance.
Thanks and Regards,
