Deploying ASP.NET application which access oracle database?

I have just developed .net application using visual studio 2008 on windows 7 which accesses remote oracle database 10g using ODAC ODTwithODAC1020221.exe and Oracle 10g express edition as it automatically installs oracle client. I do not ce开发者_如何学Pythonrtainly know what else is installed on my development computer but on I could connect to oracle database succesfully on my development machine via .NET . Now as application is complete its time to deploy it on server . Server we are using is Windows Server 2003. I installed oracle express edition and ODAC on deployment machine. I created deployment package by right clicking solution explorer of VS2008 menu and selected option publish and created deployable files on local disk. I copied all these files in virtual directory of IIS of windows server 2003. But when I could not connect to website from server it gives error as

System.TypeInitializationException: The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception. ---> Oracle.DataAccess.Client.OracleException The provider is not compatible with the version of Oracle client at Oracle.DataAccess.Client.OracleInit.Initialize() at Oracle.DataAccess.Client.OracleConnection..cctor() --- End of inner exception stack trace --- at Oracle.DataAccess.Client.OracleConnection..ctor(String connectionString) at WebApplication1._Default.Page_Load(Object sender, EventArgs e) in D:\SunilS\DOTnet\WebApplication1\WebApplication1\Default.aspx.cs:line 32
