I have Personal Oracle8 as well as JDK 1.3 installed
in my computer with Windows 98. I want to run some
JDBC programs in my machine but unable to do so.

The problem lies with the code where the connection is
being made with Oracle database. I am unable to find
out the correct combination of driver and protocol
needed.

I tried with several options but nothing is working.
My program is getting compiled but while running, it
is showing the below mentioned error.

I have the required .ZIP and .OCI files in required
folders and the CLASSPATH and PATH are set according
to that as followes.

-----------------------------------------

C:\OraWin95\bin\CLASSES102.ZIP
C:\OraWin95\bin\CLASSES111.ZIP

C:\OraWin95\bin\OCI733JDBC.DLL
C:\OraWin95\bin\OCI803JDBC.DLL

-----------------------------------------

C:\OraWin95\jdbc\lib\CLASSES102.ZIP
C:\OraWin95\jdbc\lib\CLASSES111.ZIP

C:\OraWin95\jdbc\lib\OCI733JDBC.DLL
C:\OraWin95\jdbc\lib\OCI803JDBC.DLL

-----------------------------------------

SET PATH = D:\orawin95\bin;D:\orawin95\jdbc\lib;
SET CLASSPATH =
D:\orawin95\;D:\orawin95\bin;D:\orawin95\jdbc\lib;

-----------------------------------------

And the error messages are:-

With oci7 and oci8 drivers---
java.exe JdbcCheckup

Connection conn =

Statement stmt = conn.createStatement();

ResultSet rset = stmt.executeQuery("Select 'Hello
World' from dual");

while(rset.next())
{
System.out.println(rset.getString(1));
}

System.out.println("Your JDBC installation is
correct.");

rset.close();
stmt.close();;
conn.close();
}
}

Kindly help me to solve this. Your help would be
highly appreciated.
