Torbjørn; There aren't any requirements beyond the link sent earlier.  Perhaps you could share the web.xml file offline, along with the specific calls you have tried, perhaps to [email protected]?

Hi again,

Thank you for the answers.

We tried sending requests to the TBL EVN server with Basic Authentication containing the username and password to our TBL EVN server. The server returned STATUS 200 OK, but the response we retrieved was the EVN login page. We have made sure that the username and password is correct.  We also tried form-authentication, but with no luck there as well. Just for the record, we have set up users correctly in Tomcat, and login works just as expected when we manually login to our TBL EVN server from the web browser interface.

Do we have to configure anything on the server in order to make such requests to the TBL EVN server?

Best regards,

Torbjørn

Torbjørn;

In addition, there are methods for invoking Web services, including the SPARQL Endpoint with authentication.  See http://www.topquadrant.com/docs/tbl/TBLAdminGuide/index.html#tbladmindoc_AuthenticatingServiceCalls for some details.

Let us know if that is helpful to you and if there are further questions.

Hello Torbjørn ,

EVN can be setup without authentication support. Please refer to the installation instructions here -

Also please check if the query is working on the EVN endpoint. You can do this by executing a SPARQL query against the endpoint, sending the request through the browser. For more details please see -

Hi,

I would like to submit queries to the Sparql-endpoint of my TBL EVN server from an external source. I have tried using queries based on the documentation found at http://download.topquadrant.com/evn/45doc/adminguide.html#evnendpoint. However, when I submit my query I only receive error messages, saying that it failed to retrieve query results and similar (depending on where i query from).   

I suspect the problems may be related to authentication to the server. Is there a way I could include this in the sparql-queries? Or is there some way i can configure the Sparql end-point so that i could access it externally?
