Hi, I'm involved in writing an application that will obtain data from and send data to the UK Student Loan Company via a Web service that is planned to be available shortly. The necessary schema information is contained in the Database Schema and Database Types xsd files available from: http://www.ucisa.ac.uk/groups/cisg/misgdocs/HEICourseDatabase I've downloaded the files and opened them in <oXygen/>. In order to get an idea of the kind of document I will need to be able to write into and generate from our database, I have tried to generate a sample XML file. With the HEICourseDatabaseSchema.xsd file open in <oXygen/> I do Tools --> Generate Sample XML Files ... In the dialog, I browse to the HEICourseDatabaseSchema.xsd file, for the URL. I then try to set a document root, but the Document root drop down list is empty. The HEICourseDatabaseTypes.xsd file is in the same directory as the HEICourseDatabaseSchema.xsd file and should therefore be available, so it's not that. Can anyone point out to me the obvious point that I'm missing, please? I've never had trouble generating sample files before, so I just don't see what I'm doing wrong. Many thanks Peter
