I've downloaded and installed the SQL developer and Oracle Database 10g Express Edition. I'm using WinXP. The tutorial is located at:

http://www.oracle.com/technology/getting-started/sqldev.html

I've followed the instructions but when I test the defined connection I get the following error:

status : Failure- Io exception:The Network Adapter could not establish the connection.

The Connection descriptor used by the client was:
localhost:1521:XE

In the tutorial it is localhost:1521:ORCL

Both XE and ORCL are not working.

I would appreciate any insights that would help me get this tutorial going

Hi,
the network adapter cannot establish the connection

Are you ping your computer "ping IP ADDRESS".
