Hey mate,
Thanks for the information... i tried your suggestion about the
BufferedReader and it worked... however:
Possibly there's still some gcj toolset stuff left. If you want to
solve this clean, check out the jpackage.org <http://jpackage.org/>
site and download the rpm building package. It allows you to create an
rpm file for the jdk which is compatible with "alternatives". This
way, you can switch the system JRE between gcj and the Sun JDK (and
others).
umm, can you provide more detailed info?

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:
Manifest-Version: 1.0
Created-By: 0.92-gcc
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?
Possibly there's still some gcj toolset stuff left. If you want to

gcj and the Sun JDK (and others).
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 <http://System.in>) through a
console? Because .readline( ) was the one listed in the API
It's in the API documentation:
http://java.sun.com/j2se/1.4.2/docs/api/java/io/DataInputStream.html#readLine()
<http://java.sun.com/j2se/1.4.2/docs/api/java/io/DataInputStream.html#readLine%28%29>
Wrap the InputStream in a BufferedReader and you'll get rid of the
deprecation (and gain compatibility with different character sets).

It's for FC4, but the same thing works for FC5.
