Applet teardown what is it ?

Hi All,
I have seen in java console logs "applet teardown" started logs. It would be helpfull if you can explain in detail.
My issue is that when I lauch applet, I get error "Unable to Start Plugin".
is there setting that can be done at applet side to create core dump of java process/applet so that we will come to know exact issue ?
java plug in versions are
Java Plug-in 1.6.0_11
J2SE 1.4.2 Update 5
JRE 1.4.2_16
Please note that in java console there are no errors.

OK, so now you are in the market for a display. I have no idea who these people are but this will give some guidance on price:

And then there's the sometimes murky world of eBay:

Again, no endorsement or personal recommendation, just some Googling for you.

How does one know if they use "java applets"? What do they do? How will I know if I need to 'disable the java web plug-in browser' if I do not use them? (Obviously I'm not very literate in computer-speak.)

Well, when you go to a web page a section of the web page will have a coffee cup picture where the java applet will run. The applet loads then runs. If you are not seeing this behavior then you are not using java. If it make you feel more comfortable then disable the browser java plugin. On my machine I have not disable java- but you
may what to.

Can you write to files with an applet or what?

Hi I can't get the bufferwriter to output any text to a file. Not sure if this is because I'm using an applet? I wouldn't assume so, but any help would be appreciated
The problem area is :
private boolean registerNewUser()
        FileOutputStream writer;
        try
            BufferedWriter out = new BufferedWriter(new FileWriter("logins.txt"));
            out.write(regUserField.getText());
            char [] tempPass = regPasswordField.getPassword();
            String tempString = tempPass.toString();
            out.write("\n" + tempString);
            out.close();
        catch(IOException e)
            System.out.println("Writing file error.");
            System.exit(0);
        int intSS = Integer.parseInt(regSSNField.getText());
        currentUserAccount = new Account(regNameField.getText(), intSS);
        return true;

In the future, do not post eleventeenkathousand lines of code. No one is going to read it all and - quite frankly - no one really cares.
As for the issue at hand, whenever you are going to access the file system, a remote server, access the clipboard and a handful of other "security" related issues, you must sign your applet.
Google for sun's tutorial on signing applets.

JSP applet tag X Html applet tag (what is the difference?)

what is the advantage in using the JSP applet tag instead of a simple Html applet tag ?
second question:
I have an applet in a Html frame, and a menu on the left side.... When the user select the applet option at first time, everything runs ok.. after the user select another option and then select the applet again, it fails in some features .. Why ?

well, if by "the JSP applet tag", you mean the jsp:plugin tag.. that will just generate the same HTML tag you would write. The only advantage would be it should be less typing to use the taglib.
second answer:
without seeing any code, it'd be hard to figure out the problem. The obvious thing is you are setting some state of something that is preventing further action.

Applet teardown by itself in af:popup in firefox3

this only happens in firefox3 ,no problem in ie and chrome.
and this issue really agonize me a lot. i really appreciate any help!!
the code just like this:
<af:popup id="popup" contentDelivery="lazyUncached">
<af:panelWindow id="pw1">
<f:verbatim >
<applet height="50px" width="100px" archive="audio.jar"
id="applet" name="applet" code="" codebase="" mayscript="true">
<param name="test" value="111"/>
</applet>
</f:verbatim>
</af:panelWindow>
</af:popup>
<af:commandImageLink text="pop" id="gil0" partialSubmit="true">
<af:showPopupBehavior popupId="::popup" triggerType="click"/>
</af:commandImageLink>
after click the commandImageLink ,popup shows and applet starts, but in FF3, applet will be destroyed quickly. any ideal???
thanks!!!

in the Java console,it shows the applet is destroyed. no error trace found there.
seems the space for applet in the UI disappears, then the applet instance is destroyed by java plugin.
through firebug, there will be an uncaught js error thrown.
uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: http://127.0.0.1:7101/LTWeb/afr/partition/gecko/default/opt/boot-11.1.1.3.0-0084.js :: anonymous :: line 4524" data: no]
this js exception is thrown from adf face internal js which is only for Mozilla based (gecko rendering engine) browsers.
is this maybe a adf bug for firefox3?

What're the differences between JSP, Java Script, and Java Applet?

I am confused by the concepts: JSP (Java Server Page), Java Script, and Java Applet? What are their main differences?

I don't know about differences, but one of their main similarities is that each of them has a page in Wikipedia.
JSP
JavaScript
[Java applet|http://en.wikipedia.org/wiki/Java_applet]
There. That should give you enough information.

OER Applet Error - A non-fatal error occurred when fetching an entity id

Suddenly I have a problem when I want to run 'graphic representation of related items' applet from Oracle Enterprise Repository 11.1.1.2. Thinkmap console shows up wit following message:

I suspect it's some issue with JRE, since everything worked fine few weeks ago. I've also tried to downgrade to JRE 1.5, but I still get the same error. I've tured on debugging and in java console I get this:

I figured out what is causing this problem: When connecting OER with LDAP according to documentation (http://download.oracle.com/docs/cd/E15523_01/doc.1111/e16580/extauth.htm#CEGHHGAG ) you have to disable cookie login functionality. Now i figured that 'graphic representation of related items' and 'browse tree' applets are not working if there is no cookie for user. So in order for those two applets to work I have to enable enterprise.security.cookielogin.allow and enterprise.authentication.ldap.enabled (or manually check the Enable automatic Login box).
Is there any other setting or workaround that would ensure that mentioned applets would work properly without enable automatic login option checked?! And what is the problem if I do have LDAP authentication and cookie login enabled (why is explicitly stated in documentation that I should disable cookie login with LDAP authentication?) Can someone from Oracle clarify this please?

Question regarding Applet and JVM

Hi all!
I'm working on an applet now and it's been working quite fine, just that when I run the same applet on different tab in a single browser window, it'll get some error.
But if I run the applets in different windows, it'll be fine.
So I'd like to know how does JVM handle the execution of applet?
What is the difference between:
- how JVM handles multiple applet in different-tab-in-single-browser and
- how JVM handles multiple applet in different browser?
Any help is greatly appreciated :)
Thanks in advance ^^

Sounds like you're using static fields. Not a good idea in applets because...
What is the difference between:
- how JVM handles multiple applet in different-tab-in-single-browser and
- how JVM handles multiple applet in different browser?
...that's entirely up to the browser. Actually, your question's slightly misconstrued. What you should really ask is,
What is the difference between:
- how the browser spawns JVMs in different-tab-in-single-browser and
- how the browser spawns JVMs in different browser?
Either way, it's out of your hands. Which is why you're going to have to be very careful about using statics: if you use them for state information then another applet can trash them; if you use them for inter-applet communication you might not reach one applet from another.

How do you use a main applet to call other child applets?

Hello Everyone!
I have created three separate applets that animate different colored walkers that walk across the web page with each applet doing what I need them to do. I need to create a main applet that displays a component that allows the user to select how many walkers(1-3) they would like to see displayed walking across the screen. The main applet should call only one walker applet if 1 is selected, call two applets if 2 is selected, or call all three applets if 3 is selected.
My textbook has covered how to call other classes in an application but not a main applet calling other applets. I have gone through the tutorials but have not found anything related to what I need to do. Google didn't have any good ideas.
Another possibility that would work would be to have one applet with each walker having its own method to be called based upon the selection. Then again, my textbook didn't cover calling methods within an applet.
Any hints or suggestions would be greatly appreciated on these issue.
Thanks.

Remember, an Applet is nothing more than a Panel (or JPanel for a JApplet) - basically an empty graphics container waiting for UI or graphics commands.
You do not have a "main" applet as you do when you create an executable application which requires the 'main' method.
The best thing to do, is simply do an HTTP Redirect to a page created with the desired number of "walkers". In your cause, the most you'd need is 3 walkers, so 4 pages - 1 redirect page, and then a page with 1 walker, a page with 2 walkers, and a page with 3 walkers.

Submitting a user's file to an applet.

Hi,
I am fairly new to Java, but I have spent a large part of this year learning about and using Java to write a program for biochemists, to allow them to study a particular class of enzymes. I have used Java because I wanted to enable to program to be used by people via the internet, and I wanted there to be a good graphical interface. Java Applets have enabled me to do this. Furthermore, some of the computation has to be done via the server, because the Applet interfaces to a Prolog program, and again this was easy with Java, because I was able to do this using (HTTP interface) Servlets.
There is one major drawback to this solution. The users will often develop 'models' of their enzyme, which they will want to save to a file, and reload at a later stage. However, Applets cannot access the user's file system, which means I had to find another way to achieve this. At the moment, loading (and saving) the models is done in a two-step process. A form, embedded in the web page below the Applet, is used to submit the file to a Servlet, which saves the contents of the file to a session object. Then, the user clicks on a button in the Applet, which connects to another Servlet, and the file is read from the session object, and transmitted back to the Applet. Saving a file is just the reverse of this process.
Quite apart from the fact that it is a nuisance to do this transaction in two steps, it causes problems when the user doesn't have cookies turned on. I can always alert people to the fact that they need to turn cookies on (or use URL encoding), but it still means that there are two steps to the process.
Does anyone have any suggestions how I might be able to write this sequence so that the user can load or save a file in only one step, instead of two? Someone suggested that I use sockets, but from the reading that I have done, it seems that Servlets are simply a convenient way to use sockets. So, it seems using sockets would just be a more difficult and time-consuming way to achieve the same end.
Any suggestions on this topic would be gratefully appreciated.
Regards,
Sarah

Thanks so much for your prompt reply.
Every time the user performs an action in the applet that connects to one of the servlets, I extend the lifetime of their session object. That way, when they submit a file to the server, it is available for them to access it for a couple of hours, before the session object will time out (unless the user accesses the server in the meantime, which resets the lifetime of the session to 2hrs).
The problem isn't actually passing the file from the servlet to the applet (or vice versa) - I already use IO streams to do this. The problem is can I get the file from the HTML form to the applet in one step?
As far as I can see, if the connection to the servlet comes from the html form, then the response goes back to the browser. Similarly, if the request comes from the applet, the response goes back to the applet. What I am wondering is, is there a way to force communication from a servlet to the applet when the initial connection to the servlet has come from the browser (i.e. from the HTML form)?

Applet doesn´t load in java 7 with next-generation plug-in marked

I have developed an applet with netbeans 7.1.2 which worked fine until I updated from jvm6 to jvm7. The applet does not load properly unless I uncheck from the configuration of the jvm the checbox plug-in next-generation.
Anyone know why in java 6 working properly with the plug-in next generation and in java 7 do not?
I can do something to work properly in Java 7 without having to uncheck the checkbox?
Thanks.

1 - Java installed -> 1.7.0_05-b06. In Firefox works fine. The problem is in IE8.
2 - I can run other applets.

Not working applets in win7 x64

Hello,
Maybe my problems comes from another programs in my computer, but most errors came/come from java (JRE), so I try to write a message here.... and hope to find a solution so that my applets will work. In the past periods I got a lot of script errors and watch at home only to a screen (white background with some text interchangeably) online it's really terrible for my eyes (as watching in the sun). And most program, flash-players not working online....pfff.
I installed "jre-6u21-windows-i586-iftw-rv.exe" and restarted my PC, but again my computer did't show any applet, it makes me crazy. Again I got a 32-bit version on a 64-bits motherboard.....

During the opening of several sub-directories in the directorymap Java (1.6.0_20 + 21), I found it strange that some sub-maps were empty. In the sub-folders Java/jr6/lib/applet were no files and also not in the 'lib' subdirectory ../audio.
I have search several times and downloaded several versions of Java and reinstalled them (because not working of it). I have read almost 100 pages for the correct solution, but without any result. I was searching in the folder to find information of the Java-applet or why their gone because. The Java controle on the website shows everytime "You have the last and right Java-version", but without working applets I cannot work well at my computer (offline and online).... it's a crime....pfff
So please Help me!
Under each message, e-mail or typed letter, I shall close with this signature and I can proudly say that since the year 2005 has become my lifestyle:
~ I'm open, honest and sincere to myself and others ...! ~

.Re: Rear channels not working properly in Win7\ First go to control panel, and sound, and then speakers and then to configure, and then choose 5. for your speaker setup and be sure to not choose full range speakers. Then go back to speakers and choose properties, and then Levels, and try raising your rear speakers a bit louder than your front and center speakers. For me, this works best as rear speakers do not receive as much as front and center anyway. I have my front and center set at 55 so I set the rear to 65 or 70. Then they sound equal. I turn on CMSS-3d in console Launcher and I choose surround, and then stereo surround. I do not like stereo expand.
If you have a sound source that is already 5., such as playing a 5. movie in VLC media player, the sound is already 5. so it is not "double-upmixed" per se.

What are the diffrences among J2SE,J2EE, and J2ME ?

Could one explain me..what are these terms and terms like JDK,SDK and what are the diffrences and similarities.I have installed J2sdk1.4.1 in my computer.I have written some programs and run them.Applets too.What are the extra benifits that I can take if I install J2EE.In other words what are the things that J2SDK is lacking when compared to J2EE?
Please explain..I am quite new to java.
Regards..Saman

Applet-Servlet - Creating a new file on client's mashine

Hi all!
I need to write a program, that will get a data from client through Applet text fields and save it to a new(or rewrite existing) file on client mashine. To save it, I want to use Servlet, because Applet can't do this because of security restrictions. So I think of sending data from Applet to Servlet, which will save it in a new file (will download this file back to the client's mashine).
I found the following code in forums to download a file from server to client:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class OutputFileOnBrowser extends HttpServlet {
public void service(HttpServletRequest req,HttpServletResponse res)
throws ServletException, IOException
res.setContentType("application/x-filler");
res.setHeader("Content-Disposition", "attachment; filename=out.fif;");
ServletOutputStream stream = res.getOutputStream();
BufferedInputStream fif = new BufferedInputStream(new FileInputStream("in.fif"));
int data;
while((data = fif.read()) != -1)
stream.write(data);
fif.close();
stream.close();
but I don't understand, does it automatically downloads the file out.fif to client's disc and in what path? I tried it, and it did nothing. Anyway, this code doesn't fit exactly my purpose, because I have first to create the file.
Could anybody help me please?
Thank you in advanse!
P.S. I've already wrote the Applet code, what I need now is o n l y the help with a Servlet part!
Best regards.

Thanks, but I want not client but servlet save the file automatically in a given path on client's mashine. Is there any way to do that?
Thanks.

What do I need for this?

I would to write some code where a web surfer would
enter in some data (criteria) that would be sent to a
web server where the criteria would be used to cut
a small section of a large image file and send that
smaller image back to the end users browser.
What do I need to start development (simple & quick)?
Are there java components that need loaded on the
server for this to happen?
Will applets do what I want?
Thanks!

Certainly you will want some sort of processing to take place on the server. Otherwise, all the server could do is stupidly send the entire image file. It sounds like servlets or CGI we what you want to use.

Applet teardown what is it ?
