service tag in wsdl file

Hi,

I am new to wsdl file structure. I have doubt that <wsdl:service is required in wsdl file. Why I am asking i got two wsdl files from client. One have <wsdl:service and other doesnot have <wsdl:service.

Two file names are xxxWebService.wsdl and xxxWebService_Import.wsdl.

so the second file name incluses import. Whether it is used as part of the first file. How can i know whether these two interrelated or not. Can I use wsdlToJava tool to generate jar for stub.

Please advise me to resolve this.

Thanks in advance.
