Applet thing
I've done an applet which runs perfectly on my PC. When I tried to run it on an other computer with JVM installed it only viewed gray nothingness in a browser's window. Is that JVM's difference? PC runs Java games with no problems (such as RuneScape).
Make sure the java plug-in is the same on both the working and non-working computer. go to
http://javatester.org/version.html
it will tell you the plug-in version your browser is using. make sure it's the same for both machines.

Java Applet Constantly Asks for Authentication
With have a ADF application on Weblogic 10 that has occasional access to a Java applet. The Java applet is loaded whenever it's needed and not loaded whenever it isn't in a facet. The applet is currently in the public_html/applet folder.
When we set the SSL configuration to requiring a client certificate, when the Java applet loads, it'll constantly ask for a client certificate even though the user already presented the client when hitting the website:
Request Authentication Identification required. Please select certificate to be used for authentication.
This is annoying to users and the Java Applet doesn't need authentication. Is there any way we can disable the authentication or remove the prompt?
Here's the embedded applet code:
<applet height="1" width="1" code="applet.Applet.class"archive="/app/applet/SApplet.jar" /><param name="permissions" value="all-permissions"/></applet>
Things I've already tried:
1) Setting the Applet up on HTTP instead of HTTPS; I get a warning about mixed content and still get the authentication pop-up.
2) Created a minimal applet that only types out "HELLO WORLD" in the console, still get the authentication pop-up
Here's the console window:

Import MyClass; ... not in 1.4?
I ran across this problem today.
I am using an external group of classes that are not packaged. Everything seemed to be fine in 1.3, but now I get error compiling with an import statement, and of course if I get rid of the import and just use it I get an error also.
Also, it seems to be fine with my 1.3 compiled code (using 1.4 interpreter)...
Is this some bonus feature I have yet to hear of?
Also, is there a workaround for this, since I do not control the source?

kevinoh please, and when you're puting lotsa Applets on one web page, then how do you expect intepretter to handle all those MyApplet's? it shouldn't be to hard with one MyApplet per package, but when you're having all those Applets in one ...
hey, you cannot put many classes with same name into one package, nor in unnamed package.
maybe this applet thing is badd excample, but have you not seen any other programmer have also HelloWorld.class, HelloW.class, Hello.class or HW.class?
that's why production code should be in packages... snipets, ok, these may be as well in unanamed package.
BTW: there are some tools available that help you automagically migrate class from one package to another.
so if anyone has some set of classes that need to be moved into package, then looking for such tool might be well worth of effort. -
Safari and Chrome causing OS X 10.6.7 to crash frequently (daily) on certain websites
I'm having problems with Safari and Chrome causing my MacBook Pro to crash almost daily when visiting some websites (e.g. ABCNews.com). It is happening more frequently after recent upgrade to 10.6.7, but has happened frequently since i bought this laptop. Not sure if it's an applet thing or not. Here's my problem details and system configuration output from the problem report:

First noticed issues on Chrome with websites like FB, Google Docs, some Apple support pages, Gmail, and other random sites. Chrome would show me the "Aw snap" page. Then tried resolving in Chrome by uninstalling extensions and creating a new profile with no luck. Then when I tested it on Safari, similar websites were crashing, except Safari threw up an error log immediately that looks a lot like the one above. The copied and pasted message is at the end of this post.
Then when I was editing a movie on iMovie, it started freezing up with no error messages or warning whenever I tried to edit a title manually.
It seems like a hardware issue, so I rebooted the Mac holding down D (I think) in order to get the hardware checker. Did that, no issues. Also tried repairing permissions.
If I'm seeing a pattern, I'd say that it was crashing on more complex websites like FB and Google Docs. Many other sites work fine, like this page I'm writing this post in, Google searches, etc.
I'm absolutely stumped on this one. The next thing I try will be to reinstall OS X, but I won't be able to do that for a while because it takes about 12 hours on my internet connection...
Any ideas??

Need help from people who know Java. Some beginner questions.
Hello all.
I just recently became interested in programming and I chose Java to learn (not really sure why), I am not really interested in the whole Java Applets thing because i can already do the same things in Flash. What I really want to do is to be able to make a program that can actually complete a task; for instance Is it hard/possible to fabricate a program that could say... do a simple task like open my browser, copy a file, move something ect. What type of file would it be? Would it be a standalone program or .class for MS-DOS? Also (I'v been doing examples and lessons) why are these done in my command prompt and not just executed as the program (.java?) they are (written in notepad). What is my java program export file called that can be used by others with java enviornment. I will finish an excersize and it will say congrats you've just made you first program, but if its a program then why am i running it in command prompt unlike a program i have like Adobe Photoshop where i click the icon and it opens. Is there a better language for me?
These questions may sound stupid but i'v scrutinized the internet and found very little on these topics.
Any help to any question would be greatly appreciated!
Thanks alot,
TimHello all.
I just recently became interested in programming and
I chose Java to learn (not really sure why), I am notYou should have sound reasons to pick a language...
really interested in the whole Java Applets thing
because i can already do the same things in Flash.
What I really want to do is to be able to make a
program that can actually complete a task; for
instance Is it hard/possible to fabricate a program
that could say... do a simple task like open my
browser, copy a file, move something ect. What type
of file would it be? Would it be a standalone program
or .class for MS-DOS? All java files are compiled to bytecode, which are your .class files. Anyone wanting to use your bytecode will have to have the JRE installed...
Also (I'v been doing examples
and lessons) why are these done in my command prompt
and not just executed as the program (.java?) they
are (written in notepad). What is my java program
export file called that can be used by others with
java enviornment. See the previous answer...
I will finish an excersize and it
will say congrats you've just made you first program,
but if its a program then why am i running it in
command prompt unlike a program i have like Adobe
Photoshop where i click the icon and it opens. Is
there a better language for me?Thats because it starts you out with the language basics. Almost all languages start with the historic command shell programming.
If you want to write a GUI, then you will have to use AWT, Swing, and or SWT....
There are several advanced concepts you will have to master before you can write effective GUI's..
If your looking for an easy way out, learn VB. You will need M$'s IDE to compile though.. Or VBA from within your favorite Windows APP... Many support VBA like the Office Suite, Autocad, and Open Office, and many more..
These questions may sound stupid but i'v scrutinized
the internet and found very little on these topics.
Any help to any question would be greatly

Hello,
I have an applet that reads a data file and plots a graph. Now i'm having problem converting the graph into a jpg file using a jpeg encoder.
I have the following snippet of code in the end.
File file = new File("c:\\vj\\graph.jpg");
if (file.exists()) {file.delete();}
try {file.createNewFile();} catch (IOException eIo) {}
try
OutputStream out = new FileOutputStream( file );
Image image = (Image)chart2D.createImage(chart2D.getWidth() ,chart2D.getHeight());
Graphics g = image.getGraphics();
chart2D.paint(g);
BufferedImage bufImage = (BufferedImage)image;
// JPEGEncodeParam jep = new JPEGEncodeParam();
JPEGImageEncoder jencoder = JPEGCodec.createJPEGEncoder(out);
jencoder.encode(bufImage);
out.flush();
out.close();
} catch (IOException e) {}
But when i run the applet it gives me a security exception saying:
java.security.AccessControlException: access denied (java.io.FilePermission c:\vj\graph.jpg read)
How do i fix this problem??
Any help would be appreciated,
Thanks,
Mamtha.Unfortunately, you can't do file I/O from an applet unless it is a signed applet. See applet security FAQ:
http://java.sun.com/sfaq/
If it's at all feasible, by far the simplest solution is to add a min method and make it an application instead of an applet. If it must be an applet, things get a little more complicated! Here are a couple of possibilities:
1) You could sign your applet. For an example, see:
http://java.sun.com/security/signExample/
2) You can send the file to the server where the applet came from, and then have the server write it to disk. Finally, the client can request the file from the server. For an explanation and example code, see:
http://java.sun.com/docs/books/tutorial/applet/practical/workaround.html -
Cineform raw footage samples - cs3 is ok
hiya....found this interesting stuff...if anyone wants to check it out...
http://www.siliconimaging.com/DigitalCinema/gallery_footage.html
some hd sample footage from si 2k ...
seem to be nice people at this place...mini is about $22,000 but email them and get up to 30 % discount for both mini and cinedeck ( $14,000 ).... those prices dont reflect discount... begin a conversation with them.
this neo player ( see text below....) did install the codecs for me to put the cineform raw files into cs3 and also to "play" the files on my computer using classic media player
I took the cineform applet thing out of my windows "startup" after installation ( and unchecked before removal, the "check for updates thing" )
the si 2k gallery site...with some sample footage ( some compressed for viewing only , some raw from camera with look files )
this excerpt below is in read me file in gallery page ( with raw samples )
If you simply want to
playback the files and import into AE and Premiere Pro, download NEO Player,
which is a decoder-only product. NEO player will never expire unlike the 15-day
demos of Prospect and NEO 2K.
ps...the "throwing paper airplane " thing looks nice on my cs3 after levels adj...good going.... I have to admit I like that they (cineform) teamed up with that SI 2K thing for the cineform raw format...theres some cool stuff inherent with that ( automatic half res playback on slower systems ? think I read that.... )...the looks from kodak, etc....but that stuff is already years ago....we are on crest of tech wave.
im gonna start new job soon with people who might help me find something 2nd hand that is affordable... or at least put my name out there for general gossip....so when someone wants to upgrade I can get same deal as B&H for "buy" price... about half of what they sell it for later....
in other words...im still mulling over your info ( camera you got and one you considered ), Jessica's info ( what she has now, etc )...and the full chip 35mm slr stuff available ( d5,d7 etc ).
cant buy pro camera...ever....must rent that if I ever need it. Just too much to chew on for shooting myself. need ac to pull focus etc...no way thats ever gonna happen...the cost of lenses and accesories.
gotta get computer too ( with camera ) and Im now leaning to HD ( as you suggested ). SD sucks.
I kinda like the SI 2k mini and cinedeck combo but its still way up there ( $$) even with 30% discount offered. ( 22k + 14k ) at 30% off..but they are very cool people...and there are places to rent that ( hd camera in LA for example)....
so ...no...Im still poor person with great aspirations and wanting to shoot and edit and have no camera.....
however, I AM buying a bike tomorrow for the purpose of getting into shape....so maybe I will live long enough to actually DO something besides drink beer when Im not working !!!!! -
Applet (Loading things ony once)
Is there a way to only load things that you want once with an Applet. I only want the buttons and the background to load one time and then I want paint to just move an airplane across the screen (on top of the bg). Here is the code I'm using. When I comment out the firstTime flag it works (but it flickers)
private boolean firstTime = true;
public void paint(Graphics g)
if (firstTime)
doStuff(g);
firstTime = false;
g.drawImage(airplane, xPos, 0, 150, 100, this);
xPos += 10;
repaint();
// I want this executed once. Possible?
public void doStuff(Graphics g)
// Get the width and height of the applet.
int width = getWidth();
int height = getHeight();
// Set the 'level' buttons to the lower left hand corner
// of the scren.
easy.setBounds(0,height-20,40,20);
medium.setBounds(50, height-20, 50, 20);
hard.setBounds(110, height-20, 50,20);
// Draw the background image.
g.drawImage(bg1, 0, 0, width, height, this);
firstTime = false;
}i did, but the problem was that i couldn't draw the image because i didn't have a Graphics object. When I created a graphics object it still didn't draw it.

Different things on Applets and Servlets
I use Eclipse. I create two projects: applet and servlet (deploy on Tomcat). One is with the function main, the other has doGet. In these functions I write the same string:
Mac.getInstance("HmacSHA1");
But when I run applet - it's ok, when I deploy servlet and run on Tomcat - there are exception: java.security.NoSuchAlgorithmException: Algorithm HmacSHA1 not available
How to make it availible at servlet?
Message was edited by:
AntonVatchenkoThe 2 apps (applet versus servlet) are likely using different versions of the Java runtime (and / or security extensions to them). And on one version that security algorithm exists (is built-in, or added as an extension in your JRE's lib/ext folder or something like that); while on the other the algorithm does not exist.
Make the J2EE container (the one running the servlet) use the same version of Java as the applet is. I suppose that's just a hint though, that your next question will be something like "Ok, how do I do that?". My job was just to point you in the right direction. Hopefully I've done that. -
Class not found. Or: THERE'S NO SUCH THING AS APPLETS
Okay, the problem I�m having seems to be somewhat widespread judging from the forum achieves, but I wasn�t able to find any answers that worked for me. So forgive me if I�m treading old ground, but asking explicitly is my one last attempt to learn what�s going on.
The problem is the �load: class <someclass.class> not found� gray screen whenever I try to view an applet. Now, looking around online, there are a few applets that I�ve been able to access, and many I haven�t; I�m not certain what causes some to work fine and others to gray screen, but there doesn�t seem to be a pattern to it other than the fact that if I can or can�t view one applet at a site, the same is generally true for all the other applets there as well.
Now, as for local applets on my computer, I can�t view any of them. Not examples that come with the SDK, none that I�ve compiled myself, and none that I�ve downloaded. Needless to say, in my exasperation I�ve run through every possible permutation of html code for class and classpath and so on trying to modify code into working, but to no avail.
Now, in the appletviewer, and in an IDE called RealJ, I can run applets just fine. It�s just those embedded in web pages that seem to give me trouble.
I�ve uninstalled and reinstalled j2sdk 1.4.1. I�m running IE 6.0. Windows 98SE. In my Internet options, I have under Java (Sun) the �Use Java 2 v1.4.1 for applet� box checked, and under Java VM the �Java console enabled� and �JIT Compiler� boxes checked, though I have also gone through every permutation possible here, again, to no avail.
Any idea what I can change so that I can start running applets with ease?
Thanks in advance, I desperately appreciate whatever suggestions you can give.
Travisgray screen whenever I try to view an applet.
Now, looking around online, there are a few applets
that I�ve been able to access, and many I haven�t; Basically it is partly your browser and partly the version of the jdk /sdk that you are viewing. Generally, IE does not support swing ie JApplet, JButton, JTextArea etc... which is a shame cos it has some pretty neat features - I particularly like the flexibility with textfields and textAreas - and my favourite: imageIcon, allows you to have the sexiest looking buttons in the known universe. For reasons like this, people who like to write Applets like to use swing ... and people who like Sun don't like windoze and IE and the like (and they definitely hate each other). So, if you change your browser to Netscape or Opera - you will see swinging applets galore.
Shame really on a practical level, as the last survey I saw gave IE a 85 - 90 % share of the browser market. A bigger shame, when it seems to be deliberate that m-$oft do not include the latest JVM in their browser, yet they have the latest Flash plug-in. Both are in fact a good idea.
Any idea what I can change so that I can start running
applets with ease? Don't use swing and get a copy of something like jdk1.1.5 or even 1.1.2, if it compiles OK with this then it should be OK, keep it simple - as applets download on the client-side and can be unreliable and erratic so try and avoid images. Generally though Applets are a little bit out of vogue at the moment. -
Is there any thing called applet loading timeout
Friends...
Is there anything known as applet loading timeout....
One of my applets is geting loaded on intranet 1 which is faster but is not being loading on intranet 2 (a bit slower) keeping everything else same....
please guide...
what could be the reason...
regards
raghav..yes there are no exceptions until it says class not found exception..
and yes of course they are into a jar file.

Problem with threads within applet
Hello,
I got an applet, inside this applet I have a singleton, inside this singleton I have a thread.
this thread is running in endless loop.
he is doing something and go to sleep on and on.
the problem is,
when I refresh my IE6 browser I see more than 1 thread.
for debug matter, I did the following things:
inside the thread, sysout every time he goes to sleep.
sysout in the singleton constructor.
sysout in the singleton destructor.
the output goes like this:
when refresh the page, the singleton constructor loading but not every refresh, sometimes I see the constructor output and sometimes I dont.
The thread inside the singleton is giving me the same output, sometime I see more than one thread at a time and sometimes I dont.
The destructor never works (no output there).
I don't understand what is going on.
someone can please shed some light?
thanks.
btw. I am working with JRE 1.1
this is very old and big applet and I can't convert it to something new.Ooops. sorry!
I did.

Hi all,
I am unable to delete one applet which I have loaded in the card.
There are 2 applets, one is purse and other is loyalty. And am using shareable interface in which loyalty is the server and purse is the client. I can delete the purse applet but i can't delete the loyalty from the card.

Thanks in advance......Thanks. I know they are not the same thing. A package cannot be deleted if it contains one or more applets.
I tried to delete by typing in the applet AID first, but it just doesn't work. And of course it doesn't work for package AID.
Both the package and applet AID are generated in JBuilder, which looks like this, package AID(6D 79 70 61 63 6B 61 67 31),
applet AID(6D 79 70 61 63 30 30 30 31),
instance AID(6D 79 70 61 63 30 30 30 31)
I've tried those three AIDs, it's not working.
Thanks. -
Hello,
I have a customer that is looking to set up SSO with an application that uses a Java Applet as its login screen to the app.
Any advice on how this can be set up. SSO via External Application doesn't seem to work since it doesn't use a GET or POST method.
Thank You!
PadminiAn applet (with normal security setup) can only open up socket connections to the host from whence the applet came. Sounds like your applet is trying to talk to port 5000 on the client's box. Can't do that, unless:
a) The client's box is the server (which is the case under your first scenario)
b) The applet is signed or otherwise set up to be "trusted" that it doesn't contain harmful code.
The security policy is there for a reason. I, for example, wouldn't want to stumble across some rogue applet out on the internet which then tries to open up socket connections to things on my corporate intranet or local machine -- unless I KNEW it was going to do that (I "trust" it). -
Mysterious null pointers during Applet.paint(g)
I'm working with the paint function of my applet, which uses double buffering, and I occassionally get an odd null pointer exception, which does not halt its excution, but I believe may be linked to some other unusual behavior regarding components not being painted correctly.
I've been staring at this thing for a while now and I am completely out of ideas.
For debugging purposes, I've expressly checked each object invovled in the painting to ensure that it isn't null, but the exception is still being thrown and java is telling me that the exception is being trown on line numbers that have only a closing brace (see code)
Any help is much appreciated
Here's the code... state is an extension of Container and loading is just a label to display when I'm changing different containers in and out of state
public void paint(Graphics g) {
if(offscreen == null) offscreen = createImage(500, 480);
else {
Graphics g1 = offscreen.getGraphics();
if(!dontPaint) {
if(loading != null && loading.isVisible()) loading.setVisible(false);
if(state!=null) state.paint(g1);
else {
if(g1 != null) {
g1.setColor(Color.black);
g1.fillRect(0, 0, 500, 480);
if(!loading.isVisible() && loading!=null) loading.setVisible(true);
if(g != null) g.drawImage(offscreen, 0, 0, null);
}here's an example of the errors:

}The for loop manages my networking code. Should I be putting the call to repaint() in a try block?
Does this have something to do with synchronization?
