It is possible to destroy (kill) an applet?
Hi, everybody
It is possible to destroy (kill) an applet like a Frame, as using something like:
public boolean handleEvent ( Event e){
if (e.id == Event.WINDOW_DESTROY)
System.exit( 0 );
I know that this method is used on Frame, to destroy it. Can I use something similar in an applet?
Here is the only reference in the search data on site here, for "Applet Destroy".
http://java.sun.com/javaone/sessions/slides/TT09/views10.htm
Do you mean to end the Applet? as in ending a program?
Or to get rid of the Applet as in Delete it?
Sincerely Shadow Cat

Is it possible to LOAD and INSTALL applet during pre-personalization?
Hi Friends..
Currently, i use JCOP card
I want to know the other way to LOAD and INSTALL applet not through CardManager..
I mean, is it possible to LOAD and INSTALL applet during pre-personalization time?.
Thanks in advanceHi,
i want to LOAD and INSTALL Applets while pre-personalization phase..
No, i don't want to defer the LOAD and INSTALL..In the past, we have used the pre-personalisation phase to load KDC keys onto a card and remove the ISK and set issuer specific identifiers (IIN and CIN) etc. You could also load your applet at this time if you wish. You can also load the applets at personalisation.
How do you plan on doing the personalisation phase? If you were to use a GP scripting environment for example, the CAP files are embedded as a part of the install scripts and only loaded onto a card when you begin executing your personalisation scripts. Since I assume you will be using the small desktop printers mentioned in a different thread, you may be better off integrating the applet loading into your personalisation code (printer integration) so you do not need to double handle cards.
Actually, is it possible to LOAD and INSTALL applet if we don't authenticate to the CardManager?..There are ways to load and install an applet without explicitly calling INIT UPDATE and EXTERNAL AUTH, but you still need to be authenticated to the card manager, otherwise anyone could manage card content. You can use install tokens and delegated management (which are all outlined in the GO Card Spec).
Cheers,

What To Do If Your iDevice Is Lost Or Stolen
If you activated Find My Phone before it was lost or stolen, you can track it only if Wi-Fi is enabled on the device. What you cannot do is track your device using a serial number or other identifying number. You cannot expect Apple or anyone else to find your device for you. You cannot recover your loss unless you insure your device for such loss. It is not covered by your warranty.
If your iPhone, iPod, iPod Touch, or iPad is lost or stolen what do you do? There are things you should have done in advance - before you lost it or it was stolen - and some things to do after the fact. Here are some suggestions:
This link, Re: Help! I misplaced / lost my iPhone 5 today morning in delta Chelsea hotel downtown an I am not able to track it. Please help!, has some good advice regarding your options when your iDevice is lost or stolen.

Is it possible to destroy process tree in Java?
I am creating a process using Runtime.exec(). Newly created process spawns another process and that may spawn other processes. I want to kill all these child processes when my application exits.
Process.destroy() only kills the immediate child.
Is it possible in Java to kill process tree? or is there any other way of achieving it?
Thanks
Sudhan.Depending on your operating system, create a shell script file that will call the other processes. Create another shell script file that will kill the processes created. Use Runtime.exec() to call each shell script. Not exactly 100% portable, but you are using Runtime.exec() anyway.

How to destroy the system on my lost i pad 3?thanks
If you are using iCloud, Wifi is turned on and the iPad is connected to a Wifi network, location services are turned on and Find My iPhone is installed, you can remote wipe the device.
Log into your iCloud.com account from a computer, click on Find My iPhone and go from there. You can use the Find My iPhone app on an iDevice as well if you don't have access to a computer. -
This is probably a little thing that I have forgotten but I can't for the life of me get. Ok I should probably say I am running XP, with Java 1.5 and Firefox
I have an applet that works fine on Eclipse but when I try to run it by it self it seems to die at the point where I have my input streams.
Basicly I have included the test code that removes all the input processing and tree building. This test script below just opens a input stream, creates a tree with two nodes and displays the tree. If you remove any the 3 TRYS it will not work.
I have tried various methods to read in the URL I have but it seems to die every time. I have included the code below. If anyone has any suggestions I would greatly appreciate it.
Thanks

I understand that the applet cannot connect to a server other than the one it is connected to but shouldn't I be able to connect to "www.yahoo.com"? I tried putting the URL and open stream in the start thread but it does not seem to work. When I run it in a web browser, the Java Sun comes up and it says it is inited and started but nothing comes up. Any ideas?

Background image/reloading/closing applet
2 questions:
1) How do I put a background gif/jpg image on a frame window?
2) Is there a method or command that can restart or reload the current applet?
3) What's the best normal way to kill/exit the applet? (System.exit() ?)
What about browser, how do I close the applet in the browser.
Appreciate any help.
Regards,
Helix
http://www27.brinkster.com/helixicalI think if you understand Applet's life cycle clearly you'll find answers to questions 2 and 3:
init() - initializes the applet for the first time.
start() - starts the applet after initialization and after every time it was stopped. (answer for your Q2)
paint() - does the actual painting of the applet.
stop() - stops the applet (kind of temporary), can be restarted anytime.
destroy() - kills the applet once for all. (answer for your Q3, call this whenever you want the applet to be destroyed).
answer to Q1, try the following:
in init():
MediaTracker tracker = new MediaTracker (this);
bgImage = getImage (new URL(getCodeBase(), getParameter("bgImage")));
tracker.addImage (bgImage, 0);
tracker.waitForAll();
public void update( Graphics g) {
paint(g);
public void paint(Graphics g) {
if(bgImage != null) {
int x = 0, y = 0;
while(y < size().height) {
x = 0;
while(x< size().width) {
g.drawImage(bgImage, x, y, this);
x=x+bgImage.getWidth(null);
y=y+bgImage.getHeight(null);
else {
g.clearRect(0, 0, size().width, size().height);
happy trying...

How to delete the whole array programmatically
Hello,
Is it possible to destroy/kill an array programmatically (not delete subset)? If yes, please tell me how. THanks in advance.
SugentoHi Devchander,
Thank you for your reply. I'm really surprised. Are you always working? By emptying an array, it means LabVIEW still has that particular array in memory, doesn't it? what if I want to completely destroy the array to prevent memory issue?
I have a PXI-6515, an industrial 24V DIO card, that I used to monitor optical sensors. I just found out after I hooked it up that the output from DAQmx for DIO is a 1-D boolean array. I like to be able to plot the digital signals on the Digital Waveform Graph, and to do that I have to use shift register and concactenate the previous array with the newly read digital signal. I only want to keep the array when a certain criteria is met. When it's no longer met, I want to "destroy" the array. Attach is a sample VI. Is this an efficient way to plot a Digital signal? also, since i'm using 24V, i can't use the TTL counter. Is there a VI readily available to count signal highs and lows? I have made a VI that specifically does this but I'm just wondering if there is LabVIEW function that does it. Thanks.
Peter

I will be mad if i cannot kill applet
Hi
I use whole week to look for the soltion to kill the applet(destroy).
My applet is a image slider.
So there is Image[] image = new Image[];
But when user leave the applet display page, back to menu select new images then play again. The image was still old. The applet still play the old image.
I put cache-option=no.
I disable the applet cache in Control panel aslo.
In the java stop method
i did
stop()
image=null;
System.ecit();
System.gc();
super.destroy();
All solution failed.
so i tried my last solution to close the browser and open a new browser using javascript.
But the applet console still there.
the applet seems can pass during old browser to new browser.
Who can help me?
Please give me a method.
Cause monday, my project would be demo to customer who come my place by air plane.
if cannot solve the problem, it really cannot shame myself.
YangHi ddanielvalladao
Thank you
I think your advice can sovle my problem.
My applet work process is this way:
1. html pass two parameters to applet
start frame picture name
end frame picture name
2. then applet using socket passing two parameter to server side deamon.
3. server deamon would transfer all of invovled picture in a specific folder.
4. after that applet socket get a feedback, then play those picture always named 1,2,3... in that specific folder
since those pictures are always be replaced before paly, so my applet SHOULD display all new pictures.
BUT the problem is applet is always read those same name files from cache.
now i really give up thinking the way to destroy applet. I am thinking i always put new picture in a new unique folder name.
But i have new problem also.
it is posted in arealdy.
You would find it in the Java Programming.
If you can take a look, i would be very appricated.

Is it possible to replace applet with JSP
I m working for the extension of the a Chat Application which is Applet based...
It is slow as the Applet loaded...
Is it possible to replace the applet with th JSP....
what r the pro and cons of it???
Thanks in advance...sure it is possible.
main difference is, that applet maintance a permanten connection to the server and therefor has a 'smaller' communication where as with servlets/jsp the client will have to communicate more information for each request.
have a look at pushlets.com, a servlet based framework that keeps the connection to the client open (works with hidden frames and dhtml). very smart framework. -
HTML, JavaScript, Applets possible in Web-Dynpro Applications?
Hello Community,
I'm developing a JEE5-Application using Web-Dynpro for the User-Interface. Web-Dynpro works fine for the most functions and processes of the application. But there are some special requirements i don't know to implement them using Web-Dynpro.
So my question is, if there is the possibility for:
using HTML-Code in a Web-Dynpro UI-App (the HTML dynamically generated by Web-Dynpro)
using JavaScript in the Web-Dynpro UI-App
using Java-Applets (for example to interact if local computer resources)
using an HTML-Editor for editing Texts in the Application (for example freeware Edtior fckeditor)
or do i have to use JSF in that case?
regards
MatthiasHi Matthias,
I will answer your question point wise, in short:
1) Using HTML-Code in a Web-Dynpro UI-App (the HTML dynamically generated by Web-Dynpro)
Ans: it is possible to put the HTML code in the WebDynpro UI App. Use the IFrame Ui element to do the same. See this:
http://help.sap.com/saphelp_nw04/helpdata/EN/e9/7652a84fada444bd11ca73670ce7dc/frameset.htm

Displaying HTML in WebDynpro View
2) Using JavaScript in the Web-Dynpro UI-App
Ans: Not Possible.
3) Using Java-Applets (for example to interact if local computer resources)
