Hi all,
I have successfully installed the Oracle 10g Express edition in my Lniux10.2 suse OS, after that I have set the ORACLE_HOME, ORACLE_SID and the PATH environment variables as follows.
exportPATH=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin
export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server.
ORACLE_SID=XE

Now I have this problem.
I am unable to connect the oracle database through Jdbc.
when I run the Jdbc java program, it gives me,

manickam:~/workspace # java MainClass
error: failed to create a connection object.
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
localhost:1521:database

the sid in your jdbc-url seems to be wrong:
localhost:1521:database

should be
localhost:1521:xe
