Example for using http://sparql.org/sparql.html?

Hi,

do you have an example for running a federated SPARQL query (using http://sparql.org/sparql.html)? I got an HTTP 400 error always. My queries a running well when I use a different tool such as SPARQLDroid.

update

the error message is "Error 400: Failed to load URL (parse error) http://lod.pfitzners.info/SalesOrderSearch_small.rdf : {E213} Operation not permitted". I would like use the general purpose SPARQL service to run queries an data located in an webserver without a SPARQL endpoint. I think this is not possible but I want to provide the RDF data only. The query I use:

PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX sapSLO: <http://sap.com/xi/AP/CRM/Global/SalesOrder/>
PREFIX sapAddrSnpsht: <http://sap.com/xi/AP/FO/Address/Global/AddressSnapshot/>
PREFIX sapParty: <http://sap.com/xi/AP/FO/Party/Global/Party/>
PREFIX sapUsdAddr: <http://sap.com/xi/AP/FO/UsedAddress/Global/UsedAddress/>

SELECT ?NetAmount ?TotalValues ?ProcessingTypeCode ?RootID ?OrderID
 FROM <http://lod.pfitzners.info/SalesOrderSearch_small.rdf>
WHERE {

?TotalValues sapSLO:NetAmount ?NetAmount.
?TotalValues sapSLO:ParentID ?Parent.
?Parent sapSLO:ProcessingTypeCode ?ProcessingTypeCode.
    ?TotalValues sapSLO:RootID ?RootID.
?RootID sapSLO:ID ?OrderID.
    FILTER (?NetAmount >= "150.00"^^xsd:decimal)
  }
ORDER BY (?NetAmount)
