java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver

Hi All,
I am new to DB2.I am trying to connect to DB2 through my servlet but its giving an exception

java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver

Though I have added db2jcc.jar

and my code goes like this

Class.forName("com.ibm.db2.jdbc.app.DB2Driver");
			
	       
	           String url = "jdbc:db2:DDR";
	         // get a db2 database connection
	         connection  = DriverManager.getConnection(url,"ddr", "ddruser");
	         
	         
	     java.sql.Statement stmt1 = connection.createStatement();
	     
	          ResultSet rs = null;
	            rs = stmt1.executeQuery("select * from ps_bus");

	    while(rs.next())
	        {
	        String a=rs.getString(1);
	        String b=rs.getString(4);
	       

	        System.out.println("Name:--"+a+"Owner:----"+b);
	           
	        }

but when I ripped the Jar db2jcc.jar I found only com.ibm.db2.jdbc.app but not found DB2Driver in that jar.
suggest me if need to use any further drivers.
I came to know that adding db2java.jar resolves this problem is it true?
but I have only db2java.zip,should i jar it and use or can i get jar directly from some where else

Thanks in advance
