- Alternative for deprecated method JFrame.show()I'm messing around with Java Swing. I'm also messing around with
Eclipse instead of a plain text editor such as TextPad.
When I create the following two classes in Eclipse, I get a persistent
warning that
The method show() from the type Window is deprecated
But I've checked the API docs (hence my looking for the 1.5.0 docs) and
it does NOT indicate that show() is deprecated. Any words of
guidance/advice?
Thanks

- java kerberos with DCE KDCHi all,
Before I go trying to reinvent the wheel, I figured I would ask the
experts. Has anyone had the Java kerberos client successfully
interoperate with a DCE KDC? On the surface, it looks as though it
should work. I coded up a quick test, and found that Java is using the
host field differently than DCE would like, although the rest of the
data looked OK.
Thanks in advance for any help or information on interoperability you
can provide.
Regards,
Neal

Why should it? You can't cast Object to int.

If you use a SpinnerNumberModel, then
((Number)MySpin.getValue()).intValue()
or
((SpinnerNumberModel)MySpin.getModel()).getNumber().intValue()

- differense of look between 1.4.2 and 1.4.1Hello,
when compiling and running with jdk 1.4.2 (or higher) the look is totally
different then when i use 1.4.1 fe mouse over on buttons seems different,
the look of the radiobuttons is different , how can i solve this
fe how i call a button
trashbutton.setIcon(new ImageIcon(images.getString("TRASH20")));
trashbutton.setPressedIcon(new
ImageIcon(images.getString("TRASH20_IN")));
trashbutton.setRolloverIcon(new
ImageIcon(images.getString("TRASH20_OUT")));
trashbutton.setDisabledIcon(new
ImageIcon(images.getString("TRASH20_DIS")));
trashbutton.setToolTipText(recources.getString("REMOVE_NODE"));
trashbutton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
EditRemoveMenuItem_actionPerformed(e);
}
});
trashbutton.setFocusPainted(false);
trashbutton.setBorderPainted(false);
trashbutton.setMaximumSize(new Dimension(40, 40));
trashbutton.setMinimumSize(new Dimension(40, 40));
trashbuttons.etPreferredSize(new Dimension(40, 40));
trashbutton.setBackground(new Color(15, 40, 70));
trashbutton.setForeground(new Color(15, 40, 70));
it seems when i go with the mouse over the buttons in jdk 1.4.2 the
backgroundcolor disapears and i need to set for mouseover also a color
or are there other parameters to set
there are also border that appears around the buttons on jdk 1.4.2 and not
on lower versions
can i find any solutions about this on the net?
thanks Sven

- Questions about using Java 3DHi everyone (newbie here),
I'd like to develop my skills to become a professional java developer.
I was wondering about your opinion regarding the Java 3d API. Is it
popular?
>From my google searches it looks like Java3d is most popular in the
mobile
device realm. Everywhere else it appears quiet. So for instance I

Thanks for any advise,

Well, one part of that is very definitely guaranteed: that classes in
web applications' relevant WEB-INF folders will be loaded in a class
loader that's unique to that web application. The part about shared
classes and a container lib directory is entirely implementation-
dependent.

- System.currentTimeMillis not returning GMT/UTC (J2me)I've got an application that I built for the Motorola i730
MIDP2.0 platform. System.currentTimeMillis() always seems
to return me -as stated- in GMT/UTC. I ported the application
to run against the i88s phone MIDP1.0 and the same method
is returning me the time in the Local Time.
Is this a know issue, or am I going about this the wrong
way? It would be so bad getting the local time, but it appears
that TimeZone.getDefault().getID() is returning GMT !
Any ideas?
Thanks.

looks like your <applet tag is screwed up. Besides. No self-respecting

Further it is missing a package.

Andrew -
You have the correct page <http://java.com/en/download/help/testvm.xml>
I tried your link <http://www.physci.org/pc/property.jsp> and get the
same "General Exception"...
Here is the real kicker - this works fine on my home desktop and my
work desktop - the only issue is on my laptop...and it just started
with the 1.2.0_06 upgrade...

It is doing its butterfly thing. Soon it should be reborn 10 times
faster with a new IP. The server is in transit to a new home with a
100 MBit connection. It could be back up any minute. My ISP is

I assumed the Applet you were complaining about was one you had
written. Normally an Applet goes in a package. Sun writes little toy
example applets that don't have a package.

Huh? What's that?
I recognise the two 'ClassNotFoundException's and both
'UnknownHostException's, in the original output, but
nothing else like a 'GeneralException' 'General Exception'
in there (and I've never heard of that and would prefer output
to be copy/pastes\d). Can you copy/paste the output you get in
the console, from my page?
( It does sound vaguely like a failed Java installation,
but there are some things to check before you should pursue
that.. )

Does it work in other browsers from the laptop?

Andrew -
As it turned out, the "General Exception" only rears its ugly face when
I have the "Show Applet Lifecycle Exceptions" checkbox checked in the
"Debugging" section of the Advanced Settings on the Java Control Panel.
Here is the console output from your page:

Thanks for confirming it is not just one browser.

OK. I'm guessing one of two things.
1) A bug in the 1.5.0_06 release.
The reason I mentioned this is that I saw another
post mentioning problems just after upgrading to 1.5.0_06.
<http://groups.google.com/groups?selm=email***@***.com>
<http://groups.google.com/group/comp.lang.java.help/msg/93b1cbd1c9f53bf2>
Since I am not running _06 (and am not prepared to upgrade
to it at this instant), I will have to toss the question
wider to the people who have.
Can anyone here claim to be able to point their 1.5.0_06
Java'd browser at the PhySci properties applet* (or any applet)
'and survive'?
* <http://www.physci.org/pc/property.jsp?prop=java.version>
2) A failed Java installation.
Roedy is the expert on failed Java installations, I usually run
screaming (in a shrill voice) when somebody mentions one.

- Can I link to a PDF from JavaHelpI reckon its not going to be possible but I'm going to ask....
I've done a JavaHelp system and we'd like if we could make a PDF
document available from here.
I thought we could do it as a download, right click and save target as
but when I right click it just tries to open it in the JavaHelp...
Can anyone think of a solution? The other option I suppose is to make
the document available as another option on the help menu but I'd
wanted to deploy the help jars on their own(at the moment we cant
redeploy the client)

- Please test the new 1.6.0 patchsetAll,
If you're not afraid to build the JDK from scratch without a port,
please try the "current" (new) JDK 1.6 patchset (see
http://www.eyesbeyond.com/freebsddom/java/jdk16.html). This is based
on the 1.6.0 Update 1 Build b06 JRL source.
Unless I get some showstopper reports I plan to release this as
patchset 1 sometime next week. The raw patchset itself will have
problems if you don't have the /usr/X11R6 symlink, but this will be
fixed in the port.
I haven't yet created the jdk16 port, which is why you'll have to
build it from scratch ;). It should be reasonably similar to the current
jdk15 port though.
If the build is successful you should see something like this:
> /usr/local/jdk1.6.0/bin/java -version
java version "1.6.0_01-p1"
Java(TM) SE Runtime Environment (build 1.6.0_01-p1-glewis_19_may_2007_14_14-b00)
Java HotSpot(TM) Client VM (build 1.6.0_01-p1-glewis_19_may_2007_14_14-b00, mixed mode)
(This is on i386 -- you'll see the Server VM on amd64).
Note that I'll be out of town until Tuesday evening, so I may be unable to
respond to any problems before then.

- Object creation vs. ThreadLocal retrievalI have a method which searches a singly linked list for an object. It
needs to return references to both the object and the preceding object
in the list. I have created a very simple inner class to encapsulate
this information:
private final class MemberReference
{
final Member referent;
final Member previous;
MemberReference(Member referent, Member previous)
{
this.referent = referent;
this.previous = previous;
}
}
An instance of this class will be required for just about every access
the the class, including reads, which could cause a lot of these objects
to be created and then discarded.
I'd like to avoid this if possible, but the class does need to support
reading by multiple threads, so I wouldn't want to use a single
instance (or a couple of class fields). I'm thinking of using a
ThreadLocal, but I can't help wondering if retrieving the thread-local
value might not be more expensive than creating a new object.
Anyone have any experience/thoughts?
Thanks!

- Problem with Tomcat server on windows Vista when used with javaHi,
I have one c++ application to get number of monitors from
system. I am calling .exe of c++ application using java api through
tomcat server in browser on window vista. right now I have two
monitors attached in the system.one primary and other secondary. but
when i call c++ application using java api through tomcat server, it
lists only one primary monitor.
i have some scenario for behavoiur of such application:
(1) when i run directly c++ application on vista it works fine.(gives
two monitors)
(2) when i run using sample java code without tomcat server it works
fine..(gives two monitors)
(3) when i am calling from browser through tomcat server it displays
only one monitor.
(4) one important thing is that when i call same thing on Windows XP
it works fine..(gives two monitors)
can anybody tell that what could be the problem to get list of monitor
through tomcat server on windows vista?
Ravi.

- [Off-topic] cvsHello,
sorry for the off-topic question but I think this is a good
place to ask. I plan to develop open-sourced web application
which integrates CVS browser, a bug tracking system and some
more interesting features to support development both
open-sourced and commercial projects. I would like to know
whether it is worth to invest my free time for such a tool.
CVS is rather an old system and I have no idea how widely is
used in development teams. So my question is easy: Do you use
CVS in your development?
Thank you,
jozef

- Use of scrolling in the JBuilder IDEDoes anybody know why the use of scrolling is not supported in the IDE of
JBuilder ? (the middle mouse button). Will this be supported sometime in the
future? Because it is really convienient.
Also can you tell me why the Java programs do not support the clicking of
the middle mouse button hit as an event?
Thanks in advance.

- Managing Session with javamailHi all,
I send a large number of emails using javamail. My problem is that my
provider limits the number of emails I can send out per minute per
session. On top of that, it does not allow me to use another SMTP
server than its own.
My first way to deal with that has been to include a sleep in my
sending loop in order to respect their quota (20 mails per minute).
But I now would like to explore faster ways to send emails out.
One of my idea was to close the session and reopen a new one to see if
that would be accepted by my provider server. But I don't see that
being a possilbe with javamail. Am I wrong?
Can you come up with other ideas?
Has anyone of you guys had to deal with such an issue before?
Thanks,
Necleto

- Reading a line from a fileHi to all, I'm trying to read from a file, line by line, and parse out
the data, by using the line.split(" ") function, and I have a file that
has 8 entries total per line, which means that it supposed to read up
to , array[7], but for some reason, when I run it , it says array
outofboundaries. The only thing here that is to notice, is that the
value at 7 might be either a string or an empty string, can that be a
problem?
Thanks
