How to retrieve Oracle SID from java web application

[Bahareh Nikfarjam]

Hello everybody,

Does anybody know of a API that I can use to capture the name of the database that I am connected to? Here is the scenario, I login to my application, now on the first page I want to display the name of the database I am connected to. Let say this is the entry from my tns file:
DATABASENAME =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xx.xxx.xx.xxx)(PORT = 1521))
)
(CONNECT_DATA =
(SID = DATABASENAME)
)
)
I want to display DATABASENAME in UI after I log in.

Thanks in advance!

select name from v$database

I have also seen: select instance_name from v$instance;
