The form cannot be loaded. Because the session state is not activated

I am using infopath 2007 forms in sharepoint 2007. When i want to open the forms in browser stored in the form libraries, it is saying a message that: "The form cannot be loaded. Because the session state is not activated."

How can i solve 开发者_运维问答this issue..... thank you..

In your sharepoint site web config uncommet this line in httpModules

<!-- <add name="Session" type="System.Web.SessionState.SessionStateModule"/> -->
