Hello Everybody,
I have written a small piece of code for JComponent.
But it doesn't paint the JComponent to the frame. When
I set the backgnd and foregnd colors, they are not
visible. Can you please run the code and point me what
I am missing in it?
THnaking You,

Hi Peter!
Yes! There are!
First to find out the partition do: fdisk -l. In fact fdisk is one of the
few mechanisms you can use to manipulate partitions under linux.
Second for disk size and free space do: df. Read the man for each of them as
they provide lots of usefull information.
Take Care!
I said this on comp.compilers and think it may interest some in this
news group. According to the site, the performance of this VM is
comparable to Sun's hotspot. It's released under a BSDish license.
Anyone with more Java VM programming experience cares to take a look at
it and see how hard woul

Also do not make IBM slow jikes down for shipping code : )

Well, I kinda gathered from your previously emails that we were kinda
getting out of your area of expertise, but you've still been quite
helpful. As I have searched throughout the jdbc drivers (they are not in a
jar), and they don't seem to have any libraries with them, I'll assume
they don't. I'

Jikes is the name of two separate IBM projects: a compiler (a very
active project) and a

Jikes is a Java compiler, that is it takes in source code in the Java
Language and emits Bytecod
my understanding of the Sybase JDBC drivers is that they, like Oracle,
include native code. Thus somewhere out there on your dasd around about
the same place the jdbc drivers are (probably in a jar) there should be
a lib?.so. You may only be using classes, but they could have native
methods in

No, IBM's JVM is IBM's port of Sun's JVM. It's a JVM.
jikes is a java source to java bytecode compiler

I'm sorry, but I'm obviously missing something. What *.so and *_g.so. As
far as I know the only libraries that I'm using are the ones included
with the JDK and Debug JDK Versions. I'm using class files for the Sybase
stuff. And my java files are not being compiled into a library. Maybe

Check out URLClassLoader, and email me privately if you don't get it from
there. URLClassLoader allows you load classes, resources and other "stuff"
from .jar, .zip, or subdirectory (depending on the URL(s) you pass in, of
course) without modification to your client code.

I am interesting in getting the disk space and partition
in a Java program by using JNI. What is the std UNIX API
call to do this? I have tried grepping the man pages
and got the source to kdf program but it didn't help
because it was executing `/usr/bin/df -k -T' and parsing
the output. Is there

Hi!
I'm new in Linux and Java. I have just dowloaded jdk1.2pre-v2.tar.bz2

/usr/lib/java/bin/i386/native_threads/java error in loading shared
libraries
/usr/lib/libjvm.so undefined symbol : __bzero

Hi,
I've downloaded JDK_1.2_pre-release-v2.
Each time I run "java blah_blah.class" or invoke the JVM in a C++
source, it looks as if the program is run several time. It appears 8
times in the process list ("ps").
Is there something wrong ?

There seems to be no java_g in the jdk1.2 :-(
