I am quite new to use OpenAccess ORM tool. Here is my problem. When I connect my Oracle database by using New Domain Model Wizard and step into the Connection Properties screen (click Add New Connection button, then Choose Data Source, then Connection Properties), I input my TNS Name as Server Name, user name and password. After I click the test connection button, I got "ORA-12170: TNS:Connect Timeout occurred". Does any one have a clue? I have used the TNS name and user name and password for other application successfully. My Oracle db is 9i and Windows XP.
Thanks in advance.
