wsdl or xsd??

[danjourno]

I'm pretty much a beginner here when i comes to XML and developing web services. And am just trying to get my head around it. I have done a few examples with the Java Application Server and it seems that everything evolves around wsdl files. This is fine.. But where do xsd files come into it? The Web services that I'm hoping to ultimately build are to be written to a whole bunch of standard xsd docs. or something.??

Can anyone give me a clue?

Thanks

WSDL is an XML application which makes use of XML schema constructs/data types to describe the parameters and result of a web service method.

XSD are schema files, and are used to validate your xml document. That is, you specify a certain number of rules that state what should be considered as valid on your document. When you run your schema agaisnt an xml file, it would tell you if the document is valid, if it follows the rules. Otherwise, it would say that the document is not valid. The advantage of schemas is just so that you know your documents are always correct according to the structure (or syntax in compiler parlance) that you specify.

Hope that helps

All the best
