"I am developing web service based on sparql protocol so I want to import wsdl: www.w3.org/TR/sprot11/sparql-protocol-query-11.wsdl"
Note that WSDL is no longer supported in the current version of the protocol spec, as the group has decided to remove the WSDL definition of the protocol in favor of an HTTP-based protocol, cf. http://www.w3.org/TR/sparql11-protocol/#changes.
Thus, the file you reference is no longer an official part of the spec and we no longer recommend to implement SPARQL1.1. Protocol based on WSDL.
We'd kindly ask you for a brief acknowledgement, indicating that this addresses your comment.
With best regards, Axel, on behalf of the SPARQL WG.
