Send Mail thru Oracle 9i Database by UTL_SMTP, plsql.jar not found

Hi,
Iam using oracle 9i release 2. I want to send mail thru oracle 9i database.
for that i got a procedure from net. Also they asked to follow three steps. the steps are
1. Execute the script as sys "$ORACLE_HOME\javavm\install\initjvm.sql"
2. Execute the loadjava classfile as
$ORACLE_HOME\plsql\jlib>loadjava -f -v -r -u sys/****  plsql.jar
3. Execute the script as sys "$ORACLE_HOME\rdbms\admin\initplsj.sql"

I sucessfully executed the first step, but for the second step iam not able to locate the plsql.jar file in the specified path.

So Please tell me if there is any other method to perform this task

Regards
Raja

the procedure i executed is given below
