SPARQL WSDL problems

Dear all,


I am encountering problems with SPARQL WSDL1.1 and WSDL2.0. For both I 
am using Axis2

Problems with SPARQL WSDL2.0

   1) are of an old date

   2) wsdl2java crashes on 
"org.apache.axis2.schema.SchemaCompilationException: The referenced 
element '{http://www.w3.org/2001/XMLSchema}annotation' was not found!"


Problems with SPARQL WSDL1.1

   1) appeared just several months ago

   2) wsdl2java crashes on retrieving "xml.xsd" and "xsi.xsd" (not 
found) from the web (references in "result2.xsd").

   3) I use exactly the example at 
"http://esw.w3.org/topic/SparqlProtocolWsdl11Examples"


It seems that the there some schema problems within both files.


TIA


Petr
