I want to create my own device to be compatible with the Java ME SDK, in fact it is a CDC PBP1.0 device.
Does anyone have any experience to share on this or can point me to the correct place within Sun's jumbled website.
I want to track the face using web camera in java.
How to do this? can any one tell me the way or else the link on which i can get the information about this?
I have a Ubuntu Server.
From the terminal, how should I install JDK?
In this guide it says to use this command:
sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk
But on Suns website, it says JDK includes the JRE, so why the JRE in the line above?
Anybody know how to actually install Java?
Every guide and every forum shows different ways of doing it.
BTW: It is a VPS (virtual private server)
Thanks
Hi all,
I have a Java app that has an icon in the system tray.
How can I check if the tray (or tray icon) has current focus?
Tray and TrayIcon don't seem to have .isFocused() or similar.
Is this possible?
Thanks!
Hello,
Currently, I am running Mint Linux (Release 9). I need to downgrade Java from version 1.6 to 1.5, and have been trying to figure out how to go about this. So far, I've had no luck. The package manager doesn't seem to have it.
Does anyone have any suggestions?
Thanks,

I have two Numbers. Eg:
Number a = 2;
Number b = 3;
//Following is an error:
Number c = a + b;
Why arithmetic operations are not supported on Numbers? Anyway how would I add these two numbers in java? (Of course I'm getting them from somewhere and I don't know if they are Integer or float etc).

Is there a way to manage the window z-ordering of JDialog windows within java?
I would like to able to assign each window to a layer such that windows on lower layers can never go above and obscure windows on higher layers. Even when they have focus. Similar to the Z-order capability that exists for components but for JDialog windows.
The solution does not need to work across all OSes. A linux specific solution is acceptable.
I am using the Java Robot class to take screenshots, my problem is that in W7 when the UAC dialog is shown (i right click on any application and select run as Admin) it will not appear in the screen shot or the whole screen is just black. Running my application with admin rights or as a service does not solve the problem.
Please, does any one know what to do so that i will be able to capture the screen even when the UAC is showing?
Thanks
when I call System.getProperty("java.class.path") I only get this:
/Users/pswenson/dev/sag/gradle-0.8/lib/gradle-core-0.8.jar
The other classes in question are loaded at dynamically. Any ideas on finding the full classpath?
Hi everyone,
Is it possible to write a GUI in Java that would display Japanese fonts correctly regardless of the language settings of the OS it's being run on?
I'd like to write a program which is able to do this but I'm not sure how to start going about this. Any advice would be a huge help!
I've used DbUnit but after playing about with the Play Framework recently I've found it's Fixtures.load(String yamlFilename) really useful. Anyone know of a similar tool that can be used with any Java project?
In Java an anonymous inner class can refer to variables in it's local scope:
public class A {
public void method() {
final int i = 0;
doStuff(new Action() {
public void doAction() {
Console.printf(i); // or whatever
}
});
}
}
My question is how is this actually implemented? How does i get to the anonymous inner doAction implementation, and why does it have to be final?

Hi.
I am trying to convert PDF to PDF/A.
Currently I can do this using OpenOffice pdf viewer plugin together with Jodconverter 2. But this is pretty cumbersome to do.
Does anybody of any open source / free Java libraries I can use to do this.
As we use "default" keyword as a access specifier, and it can be used in switch statements as well with complete different purpose, So i was curious that is there any other keywords in java which can be used in more then one purposes
