Opening existing apps using java.awt.Desktop

I want to display my html file using existing applications such as IE. How I can do this?
My java version is 1.6 so the java.awt.Desktop is good for my reason?

        try {
            Desktop.getDesktop().open(new File("test.html"));
        } catch (IOException ex) {
            ex.printStackTrace();
        }

Open URL in default Browser java.awt.Desktop was working...

I downloaded Net Beans 6.5 with JavaFX 1 and now java.awt.Desktop isn't even an option for the imports, is there an alternative method to open URLs from my application?

No, you aren't wrong.
It's, and I mean this with all due respect, idiotic.
I found some code on the net that does the same thing:
http://www.centerkey.com/java/browser/
Just one class, very simple.
But I really would like java.awt.Desktop to work, I want the system tray integration stuff.
Questions about getting Java 1.6 compatibility (the reason why the import doesn't work) go unanswered. It seems there is some hard coded -target 1.5 in some part of the javafx compiler. I can't figure out how to change it.

Open Folder by double click using java.awt

Hello Guys,
I have a problem. I m listing directory in List(java.awt). When i single click on directory it will open. But how i can double click on that directory then and then it will open otherwise not. By using JAVA.AWT.

According to the documentation for java.awt.List "When an item is selected or
deselected by the user, AWT sends an instance of ItemEvent to the list. When
the user double-clicks on an item in a scrolling list, AWT sends an instance of
ActionEvent to the list following the item event. AWT also generates an action
event when the user presses the return key while an item in the list is selected."
If your directories are "opening" (whatever that means) in response to a single
click, that it because of how you have written your code. Change it so that action
events rather than item events cause the opening to happen.

Open a webpage using Java

How to open Photoshop App CC on Mac desktop?

Downloaded CC trial onto my Mac OS X 10.8.4 yesterday. From there, how do I open the Photoshop app from the CC on my desktop? There is not the option to click on the app from the app list. I can click on the "More Information" below the app which takes me to the internet. I need to open the app itself on my desktop. Thank you!

Well, well, well. For all of you newbies out there, on your apps page, just like an iPhone, there's a second
"dot" indicating a second page. And there is the app. Right there. Thanks folks.

How need to take screen shot of the screen using java.awt.Robot from javafx

1) I am displaying a Stage which is having an image and shapes in it and wanted to take the screen shot as and when i move the shape( which moves the stage ).
I am trying to java.awt.Robot, but i am getting headless exception. I used
@Override
public void start(final Stage primaryStage) {
// creating some images and shapes
Platform.runLater(new Runnable() {
@Override
public void run() {
// update();
public void update() {
if (stg.isShowing()) {
ScreenCapture.capture(stg.getX() + 2, stg.getY() + 2, (int) boundsOfCircle.getBoundsInParent().getWidth(), (int) boundsOfCircle.getBoundsInParent().getHeight());
magnifierImageView.setImage(new Image(SCREEN_SHOT_FILE));
public static void capture(final double x, final double y, final int width, final int height) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
System.out.println("x ="+x +" y = "+y +" width "+width +" height ="+height);
Robot robot = new Robot();
} catch (Exception e) {
System.out.println("exception arised while taking the screen shot ");
e.printStackTrace();
The above code throws headless exception.
2) The second issues is have a image & i am dividing the image into different rows and cols( images of same size ). This is i am doing using awt. and i wanted to load those different images into
javafx images . I am facing the issues when i try to load the images into javafx.

hi,
click on print screen button in your keyboard.

How can I open a program using Java and then perform certain tasks with it?

For example, and this is just an example, I want to write a Java program that opens MS Paint and then manipulates that program. This can be useful to automate certain tasks.
My question is whether this can be done writing Java code and if so how? If not possible, would I need to use a scripting language instead?

write a Java program that opens MS Paint and then
manipulates that program. This can be useful to
automate certain tasks."manipulates" is a too wide term. Let me narrow down:
1. If you want to open (run) the program and then shut (kill) it down it is possible and fairly trivial to do in java. Look up Runtime and Process classes in java.lang package
2. If you want to open the program and edit some image/document in the opened program. It is very difficult in java. May be possible... using some Java/COM bridge, assuming your native program is COM/Active-x compliant. Note: these things go beyond the boundary of JVM and needs to interact with host OS and involves shared memory, ipc and all "low level" stuffs.
If you want to be able to play around with these COM/Activex apps- choose .NET instead :-)
3) You can open the program from java and pass it some command line arg as in (1) above and then the program will load that document/image at startup automatically. You may then edit the doc/image thru that program itself. However, Java is not doing anything for you here, other than just starting off your native mspaint.exe ot notepad.exe.

Can't find class when i use java.awt.Panel

I got a Pocket PC with CE 3.0
I made my first PJava application just a few hours ago. And it works fine. But when i introduce a Panel to improve the interface then application fails on the Pocket PC with the error message "could not find class application". When i remove the Panel it works fine again.
I thought that java.awt.* is part of PJava. And even if not i should be able to introduce even a java.lang.* class to the PJava application if i use the JAR.
Any suggestion?

you should provide more detail about your deployment procedures.
There are many ways to get this message. AWT in fact is part of pJava and works fine for most of us. So I assume the deployment is the problem. Have you checked the actual content of the JAR? Have you provided a path statement? How do you call your app (shortcut?)

Is there a way to open the mic using apple remote desktop

Is there a way to open the mircophone channel using Apple Remote Desktop so I can listen on anything thats happening at my computer at home? If not is there another software that would work?
Also is there a way to use apple's software to control and watch a PC?

Is there a way to open the mircophone channel using Apple Remote Desktop so I can listen on anything thats happening at my computer at home? If not is there another software that would work?
You would have to launch software that would accept audio from the microphone and transmit it to you in some fashion. ARD does not transmit audio itself. Another remote control solution such as Timbuktu might transmit audio, so you could look into that, perhaps.
Also is there a way to use apple's software to control and watch a PC?
You can install a VNC server on the PC and ARD can then take control of the system. It can be tricky to find a VNC system that will work with ARD, though, so search this forum for "VNC" for possible options. One of the applications that support Microsoft's remote desktop architecture such as their own Remote Desktop Connection Client for Mac or iTap Mobile RDP will probably work better, though.
