Hello,

I wanted to recover data from an oracle 9i database. I work on 64 bit systems.

I downloaded the driver ODAC112040Xcopy_64bit in which I found .dlls (among which there is Oracle.DataAccess.dll) that I added them to a windows console application under visual studio 2012 and I added Oracle. DataAccess.dll as a reference in the application. So it works for recovery.

Now, I wanted to create a web service to do this recovery.

So, I created a project of type "ASP.NET Empty Web Application" for I added an element of type web service just that displays by default "Hello Wrold". When I compile and run the application then I get the following message:



Bonjour,

Je voulais récupérer des données à partir d'une base des données oracle 9i. Je travail sur des systèmes de 64 bit.

J'ai téléchargé le driver ODAC112040Xcopy_64bit dans lequel j'ai trouvé des .dll (parmi lequel il y a Oracle.DataAccess.dll) que j'ai les ajouté à une application windows console sous visual studio 2012 et j'ai ajouté Oracle.DataAccess.dll comme référence dans l'application. Alors ça marche pour la récupération.

Maintenant, je voulais créer un web service pour faire cette récupération.

Alors, j'ai crée un projet de type "ASP.NET Empty Web Application" pour j'ai ajouté un élément de type web service juste que affiche par défaut "Hello Wrold". Lorsque je compile et j’exécute l'application alors j'ai le message suivant :
