Yes sir.It works now.
Thanks for the quick reply.

I have created jar file for my project called MyJar.jar .

1)When running in windows:
(C:\Users\Desktop\MyJar.jar has all the dependent jars in C:\Users\Desktop\testlib\)

So i run the program using the command :
C:\Users\Desktop> java -cp C:\Users\Desktop\testlib\*;C:\Users\Desktop\testlib\MyJar.jar com.abc.MyMain

The program runs absolutely fine!!!

2)When running in Unix:
/tmp/test/lib/MyJar.jar has all the dependent jars in /tmp/test/lib/*

So i run the program using the command :
/tmp/test > java -cp /tmp/test/lib/*;/tmp/test/MyJar.jar com.abc.MyMain

I get this error:

$ java -cp /tmp/test/lib/*;/tmp/test/MyJar.jar com.abc.MyMain

I am trying to connect to oracle 10 g databas on my local system. operating system is vista. A using netbeans IDE

String url="jdbc:oracle:thin:@localhost:1521:orcl"; try { Class.forName("oracle.jdbc.driver.OracleDriver"); Connection con; con=DriverManager.getConnection(url,"system","deepak"); java.sql.Statement stmt= con.createStatement(); java.sql.ResultSet rs= stmt.executeQuery("select * from kbs"); while(rs.next()) { System.out.println("values:"+rs.getInt(1)); } } catch(Exception e) { System.out.println("Error"); e.printStackTrace(); } }

I checked tha database name using the following query:

SQL> select name from v$database;

NAME
---------
ORCL

this shows that i am using the correct sid in url.
also the user name and password are correct.

But the error says:

java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
