Data services getting metadata error

Reply Threaded

Hello,
I'm using restlet-jse-2.0m5 (under JRE 1.5.0_06) to generate classes with the following code :

public static void main(String[] args) {
String[] arguments =
{ "http://localhost:2870/Orders.svc",
"c:\temp" };
Generator.main(arguments);
}

The service is a very classic ADO.NET Data Services "Northwind" database model.

I'm getting the following error :
27 oct. 2009 18:16:21 org.restlet.ext.dataservices.Session getMetadata

Any idea of what I'm doing wrong ?
Thanks in advance,

Hi Vincent,

This looks like a bug to me. Could you send us the metadata EDM XML
document so we can check why it fails?

In order to retrieve it, just type in your browser:
http://localhost:2870/Orders.svc/$metadata

Best regards,
Jerome Louvel

Salut Vincent,

Thanks for providing the metadata file. I've entered a bug report:

"NPE while parsing some metadata"

Thank you Jerome for taking care of this.

However, I need to establish a POC between ADO.NET Data Services and Java, Restlet seems the best solution on the paper but I can't make it work.

I'm following your tutorial :
http://wiki.restlet.org/docs_2.0/13-restlet/28-restlet/287-restlet/288-restlet.html

Do you have any ADO.NET Data Service example that works (since http://restlet.cloudapp.net:20000/TestAssociationOneToOne.svc in not available) or a working demo project ?

Regards,
Vincent

Hello Vincent,

Thanks for your report that helps fixing a bug during the parsing of the metadata file.
I've updated the svn repository, the next snapshot (available in about 3 hours) will contain this fix.

Regarding the sample data service TesAssociationOneToOne, it seems it has been removed by MS France.
MS Corp provides another set of (read-only I think) services called OGDI, I think you can try one of them, for example "http://ogdi.cloudapp.net/v1/dc".

Best regards,
Thierry Boileau

Hi Vincent,

The fix is now available in the latest Restlet 2.0 snapshot:
http://www.restlet.org/downloads/unstable

Could you test and let us know if it works for you? Regarding the
http://restlet.cloudapp.net service being down, we need to investigate. I've
entered a report:

"The restlet.cloudapp.net data service is down"
http://restlet.tigris.org/issues/show_bug.cgi?id=935
