Problem Executing OracleConnectivity.jar

Question

hi,
I have a strange problem when i execute the code (java OracleConnectivity) it works fine, but when i make its jar file and execute it (java -jar OracleConnectivity.jar) it throws exception
java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)

at java.lang.ClassLoader.loadClassInternal(Unknown Source)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
at OracleConnectivity.main(OracleConnectivity.java:8)
here goes the code
import java.sql.*;
import oracle.jdbc.driver.*;
public class OracleConnectivity
public static void main(String[] args)
try{
Class.forName("oracle.jdbc.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@172.16.172.221:1521:dbsettle","settlement","settlement");
Statement stm = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stm.executeQuery("SELECT * FROM rm_number_location_t");
while(rs.next())
System.out.println(rs.getString("RM_LOCATION_NUMBER_PREFIX"));
}catch(Exception e){e.printStackTrace();}
my class path is
F:\jdk1.4\jre\lib\rt.jar;F:\jdk1.4\lib\tools.jar;F:\jdk1.4\jre\lib\ext\comm.jar;C:\Documents and Settings\gohar\Desktop\stuff\wma-1_1-src-windows-i686RI\wma1.1fcs\lib;F:\jdk1.4\jre\lib\ext\classes12.zip;F:\jdk1.4\bin;
the code works even if i dont import
import oracle.jdbc.driver.*;
any slutions , thanks in advance.

Answer 1

for class file
java OracleConnectivity
for jar file
java -jar OracleConnectivity.jar
I have worked around the problem.I made a .bat file syntax
java OracleConnectivity
and it works fine
But still i cant get that why jar file was throwing Exception
