jdk2.0 (jdk.12) options ?

[Matt Zagni]

Hi,

Has anyone downloaded the solaris intel version of jdk2.0
Solaris_JDK_1_2_01_dev06_i386.tar.Z from javasoft.com (solaris developers
collection site) yet and attempted to run it under Linux using glib2.0.7pre6 ?

Although the libs look as though they may need connecting together
it may work ?

I am running glibc2.0.7 due to staroffice5.0 and Oracle8.0.5 but
my knowedge of libs is not that great linking them etc it may fail
but then again it just might work has anyone tried this version of
jdk2.0 yet ?

Any ideas ?

Many thanks

Matt

Thats between you, adaptec and the adaptec code people. You can get adaptec

downlaod Swing

[Ozer Irfan]

Hello.

Where can I download swing for Linux?
I use jdk 1.1.7

Thanks

Swing is _pure_ Java so it works on any compliant JVM. Just download it from
JavaSoft at http://java.sun.com.

timezone

[Jeroen Siffels]

Dear Reader,

It is not clear to me who is reading this message. But I hope you can
help me with my question or give me a reference where I can find help.

I'm running on a Pentium based system Linux 2.0.36 with JDK 1.1.6. My
problem is that when I use the data command om the commandline
(/bin/date) the date I see is corrent, but when I use in Java 'Data d =
new Date()'. The reported time is one hour late. In Linux the CET is
reported (I live in the Netherlands) as wanted but Java reports the UTC.
How can I make my Java software report the localtime without making my
code timezone depended (addind one hour is not a wanted solution) ?

Thanx in advance,

Jeroen

ypbind and its friends had been misbehaving: fo some reason I can;'t fathom
they weren't being started at boot time on server or workstation. Rebooted
both machines, and java's working again.

So are ypbind and its friends.

Re: jdk2.0 (jdk.12) options ?

Well,

I haven't received any mail from anyone concerning this yet so I imagine
you all must be downloading it to try ?

Does the original message look like a good possiblity that it may work 
on Linux ?

Any responces ?

set cursor in the TextField

[swang]

Hi,

I am building a java Frame with a TextField and a couple Buttons.
I would like by default, setting up the cursor in the TextField so the
user can directly type in the textfield when the frame shows.


Any help is greatly appreciated.

Look at java.util.TimeZone.

Re: timezone

[Rob Nugent]

This may well be the JavaSoft defect

http://developer.javasoft.com/developer/bugParade/bugs/4124203.html

or one of the related ones.

Basically, they stuffed up daylight savings time in a number of European
countries
including Britain. The correct solution is only implemented in JDK 1.2, so
you
may have to wait until then.

Re: Swing Core Dump...?

[TJ Saunders]

Hmmm...The new kernel didn't require glibc, as it compiled and now boots
fine using just libc5.  As a double-check, I downloaded and reinstalled
the Blackdown JDK1.1.5v6, which now works as well, Swing and all.  That
problem is solved, but it begs the question:  what was it about the
JDK1.1.6 that failed?  What I would really to like to read is some of the
documentation on what software and version, graphics libraries, etc are
assumed in the use of the Linux JDKs...

Thanks for the help!

Re: Save a canvas as a GIF file

[Mike Mondragon]

You can use the class
java.awt.image.PixelGrabber
to "grab" the pixels from an image into an array of integers.  Remember
that a java pixel is just an integer with the high bits being "alpha"
going down from Red then Green then Blue ... RGB.  Here's the code
snippet for monkeying the pixels from the API:

public void handlesinglepixel(int x, int y, int pixel) {
int alpha = (pixel >> 24) & 0xff;
int red   = (pixel >> 16) & 0xff;
int green = (pixel >>  8) & 0xff;
int blue  = (pixel  ) & 0xff;
// Deal with the pixel as necessary...
}

Now once you have an array of ints that the pixel grabber has stuffed
with the pixels from an images, or an array you have created and done
your own image alogrithms to, the array is basically in the format of a
Windows BMP file and at this time you could write the pixels to disk
with a *.bmp file extension and Winblows would be able to read/show the
file A-OK in MSPaint.  But you want a GIF right??  A GIF has its own
format so you would either have to roll your own GIF formatting
algorithm to work on the array or find something from a third party that
takes the array and makes a gif out of it.

Hope this helps.

Messed Up Date Validation In 1.1.7

[Ryan Sutter]

I don't know for sure that this specific to Linux Java so my apologies
in advance.  I am using this code for date validation:

DateFormat df = new SimpleDateFormat("MM/dd/");
try {
Date theDate = df.parse(theText);
jtf.setText( df.format( theDate )); //??!!
} catch (ParseException pe) {
System.out.println(pe);
jtf.setText("");
jtf.repaint();
}

This method allows incorrect dates like 13/9/98 without complaining.  My
testers are complaining though.  :-)  Does anybody know of a better/more
accurate date validation class out there?  Or a better way to use this
one?

Thanks in advance,

Ryan

Well, if native threading was the only problem, then one could stick with
green threads and everything would be okay.

The problem is that all those system libraries, though they have similar (or the
same) names are not the same, and this is especially true of the C libraries.
This is what prevents someone using Sparc Linux from using the Sparc Solaris
JDK. The question is is the x86 Solaris JDK iBCS (Intel Binary Compatibility
Standard) compliant? If it is, then you should be able to use it in Linux
using the iBCS kernel module. I *highly* doubt it is, though if you want to
give it a try, feel free.

BTW, I am surprised that Sun even bothers with x86 Solaris over (direct)
support for Linux. Easier to port from Sparc Solaris I suppose.

vi in win95 or winNT

[Jinpeng Xie]

hi,

I just moved to WinNT due to a job. I am using JBuilder to develop
servlet application. I really like to use vi. I hate to use editor
running in WinNT. I don't want to waste time on mouse. Do you have
some sugestion about editor like vi for PC.

I also know weblogic has a package for html development in Java.
I can import weblogic.html to develop servlet application. Do you
know we have a free package that provide a same function as
weblogic.html package.

Yes.  No friggin way.  The two are completely different in their threading
systems.  Solaris native threads uses Solaris LWPs -- Linux doesn't have them.

If I remember right there is something for setting a stricter date
validation.  Just looked it up and its setLenient(boolean) in the
DateFormat class that SimpleDateFormat inherits from.

Let me know if that does the trick!

Hi:

This is not a java-linux question but I will answer briefly.

Check out www.cygnus.com.  There is information about ports of many
unix commands to Windows.  Also check out Interix ( www.interix.com??)
and MKS toolkit.

Please restrict your questions to java-linux issues on this mailing list.

Re: TCP & SIGIO & SO_NOSPACE(sock_wmalloc() failure)

[Uncle George]

got the alpha 2.0.36 kernel from redhat 5.2/updates for alpha

still got the problem. Attached is a demo ( client/server) program that
demonstrates the loss of the SIGIO interrupt after a few EAGAIN failures. I do
not know why the loss, but for most of the failures there is a I "have no more
buffer space" failure in net/core/sock.c. BUT since SIGIO's were gen'd a few
times under the same "lack" of space scenario, i have no hard facts to point a
firm belief that the buffer failure is the absolute cause.
gat
tomm i will fire up the 386, and see how that fairs.

Running java binaries under Linux

[Steve Cohen]

The file java.txt in the /usr/src/linux/documentation directory gives
information on compiling the java kernel to provide support for running
java binaries.  (This file is in the 2.0.36 source trees and I believe
earlier ones as well.

It appears to be somewhat out of date.

For one thing, it mentions a HOWTO file supposedly available at
ftp://sunsite.unc.edu/pub/Linux/docs/HOWTO/Java-HOWTO
that wasn't there last I looked.  Is this available elsewhere?  Or even
relevant?

It then goes onto define a lot of rigamarole to go through either
involving editing the fs/binfmt_java.c source file (no thanks - I'd
rather keep my sources clean if I can) or else issuing a command to
write something to /proc/sys/kernel/java-interpreter.

How the heck do I do this?  /proc/sys/kernel is not writable and I
cannot make it writable.  The chmod command is accepted but does not
actually do anything.  /proc isn't a real directory anyway, is it?

Anyway, does anyone here have the scoop on the real way to set this up.
Also, must the java interpreter be a particular directory for this to
work?
