- Two questions about jars1) I need to support installing a Java application from CD on both Windows
AND on the Mac. I have figured out how autorun works on Windows. Is the
method for doing this the same on the Mac as it is for Windows? I am
thinking that what I'd do is create an install "program" (like the Setup
program created by Install Shield on Windows), but make it as an executible
jar file so that the Java VM on either can handle the install process. That
way, a single CD should be able to accomodate both the Mac and Windows.
2) I have found the process of making executible jar files a little
problematic, and the documentation from Sun with the SDK a little lacking in
examples: and the documentation with eclipse and Netbeans IDE is a bit of a
maze (I'd have thought that both would make it easy to create executible
jars, but I haven't found the relevant parts of their documentation yet, so
I am still struggling with hat from Sun). I understand that to make a jar
executible, I need to provide a manifest file, but I have yet to succeed in
adding one. Can anyone point me to a simple example of making an executible
jar containing a Swing application, or provide me with one (if that is
simple enough)? (And/or provide a map pointing out the relevant parts of
the documentation I have acquired) I need this jar to be self contained, so
I do not need to worry about what version of the JRE the client machine has.
I guess I ought to add a third question about whether or not either eclipse
or netbean supports making a distribution as an executible jar file that
will install the application on the client machine and create any necessary
directories and icon on the desktop? I have found, though, a couple tools
that should be able to do this, but I haven't been able to test them because
I got stuck on the question of creating executible jar files.
I am certain I can figure this out on my own, but the big problem is I am
facing significant time pressure, so I ask for aide to help me get this
figured out faster.
Thanks,
Ted

- splitting up huge (1 GB) xml documentsDear all,
I am facing the problem that have to handle XML documents of approx. 1
GB. Do not ask me which sane architecture allows the creation of such
files - I have no control over the creation and have to live with it.
I need to split this massive document up into smaller chunks of valid
XML:
The structure of the XML is quite easy:
<businessHeader>Bla, bla -> only about 10 tags</businessHeader>
<businessInformation>info goes here</businessInformations>
<!--the tag business information is repeated a couple of hundred
thousand times... -->
<businessInformation>info goes here</businessInformations>
<businessFoolter>about 10 tags footer</businessFooter>
My current approach is to use SAX to parse the document and write the
businessInformation into different files. Before that the header gets
inserted into each file and after that the footer.
This obviously consumes quite a lot of time since the entire file is
parsed sequentially.
Can you think about a way of how to speed this process up ? I was
thinking of jumping randomly into the <businessInformation>-section of
the file (Random Access File) and then start parsing from there on with
SAX (potentially in parallell by using threads) but I am not sure if
this works.
Any hint is appreciated.
Cheers

- Adding JPanel to JLayeredPane - Please help!Hi
I have a problem adding a JPanel to a JLayeredPane.
The class ChartGraphics paints a system of coordinats / Chart on a
JPanel
using the paint() metode. When I add the ChartGraphics object directly
to the Contentpanel of the frame the Chart is shown without any
problems. But as I want to add some buttons on top of the Chart, I
want to place it in a JLayeredPanel, and afterwards add the Jbuttons.
The problem is that the Chart is'nt shown if it is placed in the
JLayeredpane, why? The Button is displayed nicely.
Can anybody tell me how to display my JPanel background from the
JlayeredPane?
/Thanks
Kristian

- Single Threaded EnvironmentHi,
I know this might not be the best place to ask this but.. umm I know
Java is a multithreaded environment. what do you call a single threaded
environment where there are no multiple threads or scheduler? Please
tell me because I can't seem to recall the term :( Is it just "single
threaded environment"? Or is the term something else? Thanks!

I just ran into the same problem. Upgraded two win98se machines to XP

install the 1.4.2_04 jre. I have the same jre running flawlessly on
two preinstalled Dells with xp pro sp1. Very interested in a fix,

- Web Application Works on Windows, Not on Linux (Needs a file)I've been using a web application to find part numbers and info for an
antique car I've been working on for a while. I used to go to the
manufacturer's website, log in ($20 a year fee, otherwise I'd link to it),
click on the link, and the program would run just fine under Linux.
Recently I upgraded my system (from Ubuntu Edgy to Ubuntu Feisty) and now
this app will run in Firefox on Windows XP but won't run on Linux. Now I
get an error that it can't find the file hpwin32 in the java.library.path.
(The full stack trace is below.)
I searched my hard drives on the WinXP system and there's no trace of this
file, so I'm guessing it's a file on their end that isn't loading. This
worked fine when I was using Java 1.4.2 but won't work now, with Java 6
installed.
Any ideas on what I can do to make this work again? What other info would I
need to provide that might help track this problem down? (The supplier
doesn't officially support Linux, so I can't get help from them.)

- Java and MySql program example ?I am trying to learn Java and need an example program with MySql
database.
I am sure there are many who have made an invoice program in Java with
MySql database. The program must have routines that are similar to
those an invoice program has: customers, orders, products. Screens
like orders head and orderlines.
Can you please send me a copy of the source files for such a program
or a different program?

- OutOfMemory on Sun Java 1.4.2 on LinuxHi all,
My application (on JBoss) is experiencing strange problem on one of our
environment - on Linux on Itanium 2 - Sun Java 1.4.2_07 and 64 bit.
On all other platforms (windows, linux, 32 bit) is ok.
After 2-3 http requests the OutOfMemory exception is thrown.
Java is started with -Xmx1024M. In fact the bahaviour is exactly the
same as -Xmx512M.
'uname -a' shows unlimited resources for memory.
There is plenty of free memory in the system (main and swap) - for
example I can run 3 such java processes at the same time - but each is
reporting out of memory after few requests as it is for one java spawned.
'top' shows that java eats ~400M when the OutOfMemory is thrown.
Where to look, what to check?

- awt Dialog color problemHi, I'm using jdk 1.1.8 on an embedded application which runs under Personal
Java on VxWorks (I think). But anyway, that may not matter. I'm displaying
an awt Dialog and the color of the title bar is a pretty ordinary looking
red. I'm guessing this comes from O/S like it would in MS Windows. I have
no access to the operating system to change this. Is there any way to
change system colours in java?

- Resizing images thru a java program
hi
I need to capture an image based on the URL of the image provided by
the user and do the following things
1. Create a thumbnail
2. Resize the image
I may have to store these two images locally or just recreate these two
images and display it in the browse.
What are the best tools to use to achieve this? I need a Linux/java
based solution. Will Imagemagick.org do the magic?

- GCJ 4.1 and OpenOffice.orgFWIW, I have been working with Eric Anholt to have Kaffe (java/kaffe)
supported by bsd.java.mk. The only thing with miss is a port of a
Javadoc tool so that ports documentation may be built without any Sun or
IBM JDK. I believe gjdoc (can't remember if this part of classpath or
another "free" Java tool) could be used in place of javadoc.
I'll have a look at your wrapper and modifications in the next few days.

- How to kill thread which is blocked by Serversocket.accept()?Hi;
I have got a network-thread running in the background listening for
connection-attempts.
The thread uses an instance of Serversocket and its accept() method to
listen.
After a certain period of time i want to kill the thread if no connection is
established.
The problem is: the accept-method blocks until someone connects.
Therefore it is not possible for me to use the interrupted-flag and check it
within a loop in my
thread to signalize it to end (the recommended way to kill a thread). I dont
want to use the thread.stop
() method since it is deprecated, but even when i try to use it i can not
kill the thread.
Within my gui thread i tried to use a swing timer, but it doesnt kill the
thread:
timer = new Timer(TEN_SECONDS, new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if (networkThread.isAlive) {
timer.stop();
networkThread.stop();
//...Update the GUI...
}
}
Anybody there who knows a proper way of killing such a blocked thread?
Thanks in advance,
Jan

- Execute jar in program codeI have a jar file, without source code, say abc.jar.
I have set it in the CLASSPATH
The main execute class in abc.jar is a.class.

But I would be like to embed it in my program.
Can I create a "dynamic" instance from it?

- Signed applet focus problem,.Hello,
I have a jsp page which contains a signed applet which reads some
System properties.
I am using jdk 1.4.2_06. and IE 6.028.
When the signed certificate appears, if I click on the Internet
Explorer icon in the task bar, the certificate goes below the browser.
Now since the certificate is supposedly modal, My browser loses focus.
ie. I cannot bring the certificate to the front sans tabbing and the
browser will not respond to user input. The only way to get the
certificate to the front is by "tabbing" till I get to it.
Any one seen this behavior before? If so any suggestion would be
appreciated.
Thanks

- Dying hype: Slowing sales of iPhone
Well, the hype sure died fast. For those morons who think 700k units
were sold over the weekend - hey idiots, that's an ESTIMATE from one
source, and the most generous one at that. The range of sales
estimates is from 250k to 700k.
In fact, some analysts have downgraded sales projections for next year
from 12 m to 8 million based on the fact that supply seemed to be more
than demand.
think about it morons. ur selling 8 million phones in a 1 BILLION unit
yearly market.

- Runtime - external program visibility
Hello,
i use the getRuntime method to start an external program out of
my Java app: Runtime.getRuntime().exec(cmd);
where cmd is an array of String
String[] cmd =
{ "\"c:/Whatever.exe\"","/user=User","/password=XXX"};
Now the issue is that the program (Whatever.exe) starts, it
accepts the parameters (user,password), - the / is required by
Whatever.exe - but the window of the application Whatever.exe is
not visible! The process is there (one can see it in the
taskmanager).
In Delphi i have the possibility by using Windows.CreateProcess
and passing a "StartupInfo"
(lStartupInfo.dwFlags:= STARTF_USESHOWWINDOW;
lStartupInfo.wShowWindow:= SW_SHOWNORMAL;) but here in Java i dont see a possibility of determining in which way the external app is being started up or determining its visibility.
kind regards
