[Java] Development Kit Issues

Hey mates,

I need to inquire about two issues in particular regarding JDK... Firstly, so that you can understand my background:

- I'm running FedoraCore 5
- In the FC installation, I installed the regular Java Development libs & tools (such as eclipse, gcj, ...etc)
- I downloaded and installed the JDK1.5 and the JVM from Sun Microsystems, Inc.
- I removed all the java related bins in the /usr/bin folder, then recreated the links to the new bins in the /usr/java/jdk1.4.0/bin library to make the javac, java, jar, javah... etc commands use the new JDK

Now here's my problems:

A) When i create a jar file (ex: jar -cf Anyfile.jar Anyclass.class), the manifest file created with it (META-INF/MANIFEST) lists:
where you see, that my problem is that the manifest file was created by "gcc" apparently, and not 1.5.0_01 (Sun Microsystems Inc.) which should have been the case... so, how can i change the manifest file maker?

B) When developing this simple program to test reading & writing to an input device keda bagaraboh that replaces the keyboard for the ( System.in), i get this message when compiling with javac... However, this message is not an error, it is just a note... the program DOES compile, yet i don't know what is causing the bloody note...

The Program:
import java.io.*;

public class ReadingFromConsole{
        public static void main(String[] args){
                //propmt user
                System.out.println("Say something");
                //set the input stream
                DataInputStream IStream = new DataInputStream(System.in);
                //read the dara
                String UsrInput = new String();
                try{
                        UsrInput = IStream.readLine();
                } catch(IOException e) {
                        System.out.println ("Error getting input");
                }
                //print the data out to the user
                System.out.println("You said: " + UsrInput);
        }
}

And the Note I Get after compiling with (javac -Xlint:deprecation ...etc):
[ahelmy@Laptop Java]$ javac -Xlint:deprecation ReadingFromConsole.java
ReadingFromConsole.java:12: warning: [deprecation] readLine() in java.io.DataInputStream has been deprecated
                        UsrInput = IStream.readLine();

So, does anyone know a replacement to read directly a line of user input from the ( System.in) through a console? Because .readline( ) was the one listed in the API

Sorry for the long mail, but I hope that through the [java] tag, anyone who's not interested can just ignore the mail
