I am new to Salesforce and learning how to integrate Informatica with Salesforce.

I recently created a Salesforce Developer Edition account but I am not sure of how to import the Salesforce objects into Informatica. If I use the default informatica provided Salesforce Service URL(https://www.salesforce.com/services/Soap/u/7.0) I am getting the following error message "Login failed. Error code:[SOAP-ENV:Client] Reason:[No Data]"

What is the Service URL to be used in Informatica to access Developer Edition account?
