Hi there, I'm new to csla and I'm struggling. Yeah, I really am!

My configuration is SQL2005, VS 2008 and Windows XP. I tried to follow the instructions in http://www.lhotka.net/files/csla20/BuildCsla.pdf but the PTWeb-project is giving me a hard time.  The error message I get is down here. Can anyone give me a clou? I m using CSLA 3.0.0 and using IIS for the project and not the VS built in Web Server

thanks in advance, Bharat

Do you have other working web sites on that server? The exception stack trace makes it look like ASP.NET is failing long before it gets to your code or CSLA .NET code...

thanks for the reply.

yes you are right ...whenever i am trying to use IIS for my current project it is giving the same error but it is working fair enough under VS web Server.

so i dont have any idea what to check for this as my current project is also using CSLA and it is working fine under  VS web server but not not working under IIS and i am new developer assigned to this project so trying to hands on CSLA and configuring projecttracker but failed.

please help...

Thank you very much for your help and reply.

i resolved that problem and now i can able to see the Login page of project but while logging i am getting below error..

 

this error i guess is because of missing of below step..

7.The PTWeb and PTWebService projects are configured to use the

EnterpriseServicesProxy within the data portal. Before you can run these

projects you need to start aVisual Studio 2005 Command Prompt window and

run regsvcs.exe to register the EnterpriseServicesHostvb.dll or

EnterpriseServicesHostcs.dll file. Alternately, you can change PTWeb and

PTWebService to use either the Remoting or Web Services proxies instead.

If you do use the EnterpriseServicesProxy, you must also open the COM+

Applications properties window for the service and set the Application Root

Directory in the Activation tab. The path should point to the same

 

But i need to know is there some alternate to this option as i could not able to get the Component Service on my machine.

please suggest.

waiting for your reply.

thanks in advance.

I'd change the configuration to use the local dataportal mode only; that is, remove the line specifying the kind of dataportal to use in the configuration file. 

Once you understand this setup, then move on to trying to get a remote dataportal setup to work.
