Problem in PostgreSQL - jdbc

I want to know how to use jdbc for postgresql in red
hat linux 7.0. I have installed red hat linux 7.0
completely and there are four jdbc.jar files of
different version.There are no postgresql.jar and
finder.jar files. I found two different methods for
jdbc interface:

1) Just set the path
CLASSPATH=$CLASSPAH /usr/lib/pgsql/jdbc6.5.1.2.jar
and compile the program.

But when I compiled the program using jdk1.1.2
there was an exception CLASSNOTFOUND. When this
exception was caught it gave the error message
"postgresql/driver"
How do I set the driver? I used the statements:

Driver driver = (Driver)Class.forName
("postgresql.Driver").newInstance();

DriverManager.registerDriver(driver);

String url = "jdbc:postgresql:jtest";

Connection con = DriverManager.getConnection
(url, "postgres", "postgres");

Statement stm = con.createStatement();

Do I have to use "org.postgresql.Driver" instead
of "postgresql.Driver"?

2) Change to directory src/interface/jdbc and type:
% make
to get postgresql.jar and then set the class path
to:

export CLASSPATH =
/usr/local/lib/finder.jar:/usr/local/lib/
postgresql.jar:.java uk.org.retep.finder.Main

This src/interface/jdbc is not in any of the
postgresql directories (installed from red hat
linux 7.0)I therefore downloaded
postgresql-7.0.2.tar but some classes were missing

in it.
If I'll succeed in getting postgresql.jar from
this method then how will I get finder.jar?

I found in the same mailing list to rename jdbc6.5.1.2
.jar to postgresql.jar and then set the CLASSPATH. But
it also didn't work out.

Can someone please help me?
