I am currently using Delphi 6. I have a lot of experience creating client/server apps, but very little with web services. I am creating a j2ee based web service that will act as a report server. The server will return (often very large) XML files containing the report data. I may also want to pass back an xsl file. To get started in an attempt to familiarize myself, I created a simple web service that returned a small string. Getting the client and server to work for this was fairly simple. My next step was to create a web service that generates a file and transfers that file to the client. I set up the webservice which now returns a Java Source type (it's actually a DOMSource). I don't really don't even know where to begin with this in Delphi, however. I guess I basically want to know how to deserialize the DOMSource or if I should be passing the file back as a different Java type and how to go about deserializing that Java type. If I generate pascal file for the interfaceusing the WSDL wizard, the resulting interface contains a function that returns a Source type, something of which Delphi has no understanding.

Thanks for any help in advance.

Hello Christopher,

I can't say for sure until I see the WSDL but your best bet to pass a file
is to deal with byte[]. Both Delphi and Java will base64 encode the data and
interop. Each SOAP stack has proprietary extensions that don't necessarily
work with others. I've never run into 'Source' but I know that Java
WebServices often expose types such as 'Array' or 'Map' that work with other
Java clients.

If you can point me to the WSDL of the service I can see how things could
work between Delphi and the service.

Cheers,

Bruneau.
