Configuring JDeveloper 11g

Question

Hi,
I have installed JDeveloper 11g (11.1.2.1.0).
Currently I am trying to configure it, so that I can create and run the ADF application.
I think when we install JDeveloper 11g (11.1.2.1.0), a database also gets installed along with the IDE, however I am not sure on this.
When I am trying to create a connection by giving the following info, I get the standard connection error.
Test failed: IO Error: The Network Adapter could not establish the connection
User Name : hr
Password : hr
Hostname : localhost
Port : 1521
SID :XE
Now I am not quite sure, how to verify, if the data base is installed and is currently UP and RUNNING.
How can i resolve this connection problem.
Thanks
Saurabh

Answer 1

Yes, I am able to connect thru JDeveloper. This is fine.
But when I open the command promp and give the command tnsping XE, then it does not identify the database.
C:\Users\ion>tnsping XE

Please tell me what is missing.
C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN
======================================
Here I have my database installed and the TNS file here, reads as you have mentioned in above post.
But if you look at the tnsping XE command output, somehow, it is pointing to some other location in my C:
I am not sure, if there is any environment variable or something needs to be set to correct this.
