Applet Reinstallation
Hi ,
Iam already load one applet to the GemCombixpresso R4 card using GPShell
and next i want to upload another applet ...
Do i need to delete the existing applet?I tried to deleting Pkg and applet..
when i tried to delete the applet and load the another applet,it is giving error 6A80...
what's the problem?
Please provide an APDU trace. I assume you deleted the applet only and tried to load the package with the applet again. You need to delete the applet first, then the package. Alternatively you can use (if supported by the implementation) the enhanced GP DELETE command, deleting object and all related objects; this means you apply this delete to the package and it will delete all applets having a dependency with this package as well.
If your applet did not change, you don't need to load it, just instantiate out of a package module.

Applets stopped showing after reinstallation
I noticed recently my browsers stopped showing applets. IE, Firefox, Opera don't show any applets anymore.
I have been doing a lot of reinstallation recently.
Now I have J2EE in C:\Sun\AppServer with JDK in C:\Sun\AppServer\jdk and JRE in C:\Sun\AppServer\jdk\jre.
I can view applets with appletviewer, but my browsers just display an empty image.
Can anyone offer any help?In the tools - Internet Options-Advanced of the browser (IE), check whether proper selection is made for the applet

Flash Player linux, grey box issue (youtube vids and some applets do not display)
I posted this question on my distro-specific forum as well as linuxquestions.org, however it appears to be a unique problem, so here it is:
When viewing videos on youtube.com, most other websites, and when trying to run certain flash games, the flash applet will not display (though the audio will play). Instead of displaying the flash applet, there will be a grey box where the flash video or applet would normally be.
This problem occurs on Firefox and Chromium, but not on Opera.
My Specs are as follows:
Distro: PCLinuxOS 2010 (32-bit)
flash-player-plugin: 10.1-2pclos2010
firefox: 3.6.6-1pclos2010
swfdec has never been installed (to my knowledge)
I did a lot of investigating about the problem but have turned up no solutions thus far. Here are my results.
Flash videos and applets which allow access to the settings menu (like youtube played from their website) do not display, however flash videos and applets which do NOT allow access to the settings menu (including youtube videos embedded in other websites) WILL display.
Reinstalling flash-player-plugin and firefox through synaptic does not solve the problem (though note that PCLOS works with rpm files, not deb files. apt4rpm does not support the remove --purge operation, however reinstalls are said to overwrite custom configs with stock ones.)
Creating a new firefox profile and/or starting FFox in safe-mode does not solve the problem
Creating another user and running FFox from that user will properly display flash videos
Comparing default plugins between my main user and new user shows that there is no difference. So this likely rules out a defective extension or plugin binary.
Deleting ~/tmp/plugtmp* folders when FFox is closed does not solve the problem.
Removing the ~/.macromedia and ~/.adobe folders does not solve the problem. (have checked permissions between the new test user and main user, and they are equivalent)
Downloading libflashplayer.so from the Adobe website and copying it to /usr/lib/mozilla/plugins has no effect on the problem.
I'm thinking that there might be somewhere else that flash stores configurations for my user, and that maybe the settings there are corrupted and would need to be purged. However frantic googling has turned up nothing useful so far.
Does anyone have any suggestions for me?The problem, at least in my case, was QtCurve's opacity. If I have opacity set to less than 100%, flash would not display for sites like Youtube and Vimeo, but worked elsewhere.
The solution for me was to go into qtcurve's settings, and put npviewer.bin in the application exceptions section for window and menu opacity. Doing that, I was able to keep my transparent menus, and also use flash everywhere.
You can find out what the application name is by launching your browser of choice in a terminal with qtcurve debug turned on, like so:
QTCURVE_DEBUG=1 firefox
If you watch through the lines that start with "QtCurve" you'll see "Application name". Look for the one that shows up when you try to load a video. In my case it was npviewer.bin. In yours, it might be nspluginviewer or something else. If you add an exception for that specific application, you'll fix your problem without having to compromise on your theme. -
Applet not loading in IE from Builder 904
SUMMARY
When I launch my Form from Builder the first time it works. Any subsequent launches from Builder do not work. Instead IE shows HTML in the browser window. The only way to get it to work again is to restart Builder.
If I change my default browser to Firefox this problem does not occur. (However I need to use IE as that is what the clients will use and there are differences in the layout.)
DETAILS
Environment:
Windows XP Pro
Forms Builder 904
IE 6.0.2900.2180.xpsp_sp2_rtm.040803-2158
JInitiator 1.3.1.17
Upon first run from Builder IE shows 'ORACLE FORMS' in the browser area. The Information Bar in IE says
'To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer. Click here for options...'
I click the Information Bar and select Allow Blocked Content. Then the Applet loads successfully.
On subsequent tries I do not get the Information Bar. And the following HTML appears in IE.
<html> <head> ORACLE FORMS.</head>
<body onload="document.pform.submit();" >
<form name="pform" action="http://GEN2TEK-LAP03.bullwip.com:8889/forms90/f90servlet" method="POST">
<input type="hidden" name="form" value="C:\formswork\mywork\Sandbox\TEXTIO_TEST.fmx">
<input type="hidden" name="userid" value="ORATORFORMS/ORATORFORMS@ORATOR_TEST.METALSAROANOKE.COM">
<input type="hidden" name="obr" value="yes">
<input type="hidden" name="array" value="YES">
</form> </body></html>
This problem occurs with any Form I've tried.
I've tried changing IE security settings to the most insecure settings (for both Internet and Intranet). This hasn't worked.
I've tried Disconnecting and Reconnecting within Builder but that doesn't work. Builder has to be restarted.
I've tried uninstalling JInitiator. After it reinstalls the same problem occurs.
-JeromeI've found a workaround that I can live with. I made a bookmark in IE to:
http://gen2tek-lap03.bullwip.com:8889/forms90/f90servlet?form=C:\formswork\mywork\Sandbox\TEXTIO_TEST.fmx&userid=SCOTT/[email protected]&obr=yes&array=yes
Then when I launch the Form from Builder and get the HTML I just click my Bookmark and it works. -
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.
public void start() {
public void stop() {
public void destroy() {
try {
resetAll();
Configuration.closeConnection();
QuoteItem.closeConnection();
} finally {
try {
super.finalize();
} catch (Throwable e) {
e.printStackTrace();

I'm developing an applet that has to open some web pages.
The only way I know is to use the method showDocument that
needs and URL. So, how to pass parameters to the web page?
I don't want to put them in the URL: everyone can see
"secret data"!
Help me, please.Take a look at this example that uses a JEditor pane to hold the HTML page.
//Create a new JEditor Pane
jep = new JEditorPane( );
//Ensure the pane is not editable
jep.setEditable(false);
//Use this to get local HTML file
URL fileURL = this.getClass().getResource("Manual/Manual.htm");
//add the html page to the JEditorPane
jep.setPage(fileURL);Ok the core line of code here is this.
URL fileURL = this.getClass().getResource("Manual/Manual.htm");The standard method for accessing a html file via a URL is thus. As you can see its very similar.
URL fileURL = new URL("http://www.comp.glam.ac.uk/pages/staff/asscott/progranimate/docs/Manual/Manual.htm");this.getClass().getResourse() will return the file location of the class you are working with.
By doing the following you can access manual.html in a folder called Manual that sits in the same file location as the class file you are using.
URL fileURL = this.getClass().getResource("Manual/Manual.htm");I hope this helps.

Unable to load database driver from my applet's jar file
I'm trying to set up an applet that will talk to a MySQL database. I have no problem connecting to the database as I'm developing the code ("un-jarred"), but when I create a jar file of my code to test through a web browser, I cannot connect to the database due to the usual ClassNotFoundException. I have included mysql-connector-java-3.1.12-bin.jar (the current driver) in the jar, but I don't know if I'm supposed to supply some info through an attribute to the applet tag to let it know that the jar contains the driver it needs or if I have to call the driver differently in my code.
Any help is appreciated, thanks.The simplest approach is always the best. :)Abso-lutely.
Awesome, that worked perfectly. I Included the extra
jar file in the applet tag and now my applet makes
some sweet lovin' to the database.And you have succeeded where thousands have failed. Congratulations. -
Applet java file not refreshing in browser
I have an applet that I am updating and I am not seeing the corresponding update when I open the web page. I can manually download the java class file and look inside it and it definitely is the updated file. I have deleted the browser history. (I am running tests with Firefox 3, IE7, and Safari 4 public beta). Is there something else I need to do to make sure the browser pulls in the latest version of the class file referenced in the html?
Here is the code:
<HTML>
<HEAD>
<TITLE>A Simple Program</TITLE>
</HEAD>
<BODY>
<CENTER>
<APPLET CODE="SendRequest.class" WIDTH="500" HEIGHT="150">
</APPLET>
</CENTER>
</BODY>
</HTML>The applet refers to a hard coded URL to read through a urlconnection. It is always reading a file and showing content, but it is not showing the right file. If I change the name of the referenced file in the java program, it looks like the browser has cached the referred file, rather than throwing and error and saying the file doesn't exist.
Here is the java
import java.applet.*;
import java.awt.*;
import java.net.URLConnection;
import java.net.URL;
import org.w3c.dom.Document;
import java.lang.String;
import java.io.*;
public class SendRequest extends Applet {
@Override
public void paint(Graphics g) {
g.drawRect(0, 0, 499, 149);
g.drawString(getResponseText(), 5, 70);
public String getResponseText() {
try {
URL url = new URL("http://myserver.com/stats/logs/ex20090603000001-72.167.131.217.log");
URLConnection urlconn = url.openConnection();
BufferedReader in = new BufferedReader(
new InputStreamReader(
urlconn.getInputStream()));
String inputLine;
String htmlFile = "";
try {
while ((inputLine = in.readLine()) != null)
htmlFile += inputLine;
in.close();
return htmlFile;
} catch (Exception e) {
return "Can't get the string.";
} catch (Exception e) {
return "Problem accessing the response text.";
}Any help would be appreciated. I heard that some files may cache more persistently than others, but I don't fully understand the details.
Thanks,
JimCheck this [document loader example|http://pscode.org/test/docload/] & follow the link to sandbox.html for tips on clearing the class cache. That relates specifically to caching a refused security certificate, but class caching is much the same. As an aside, getting a console can be tricky in modern times (unless the applet fails completely). It is handy to configure the [Java Control Panel|http://java.sun.com/docs/books/tutorial/information/player.jnlp] to pop the Java console on finding an applet (Advanced tab - Settings/Java Console/Show Console).
Of course there are two better tools for testing applets, especially in regard to class caching. AppletViewer and Appleteer both make class refresh fairly easy. Appleteer is the better of the two. I can tell you that with confidence, since I wrote it. ;-) -
EJB 3.0 - Communicate an Applet with a Session Bean
Hello
I'm developing an EJB 3.0 app (eclipse and glassfish tools bundle), and I have an applet that has to use remote session beans.
QUESTION: Is it possible for the applet to connect to EJB?
QUESTION: By creating a J2EE application client project, can I use @EJB annotations to inject the session bean directly to the applet, avoiding the JNDI lookup?
(since I imagine that the anwser to the second one is NO, I do the following consideration)
Given an application client project, I imagine that this application can run remotely on a client machine/JRE. Then this application can use Annotations/injection facilities whenever it runs on a J2EE client container (which I assume consists of a set of libraries provided by the application server vendor, Glassfish in that case). Could this application be deployed using Java Web Start? If so, why can't it be deployed as an applet? (both options run in a client JRE, don't they?).
QUESTION: In either case (applet or JWS), how do I have to package the JAR file (using Eclipse) so that it contains the needed libraries for accessing the EJB? Which are those libraries?
At the time being, I'm trying to implement a sample application that follows the "Applet doing JNDI lookup" approach. I have:
- an EAR project
- an EJB project (containing an Entity Bean and a Stateless Session Bean with a @Remote interface)
@Remote
public interface HelloRemote {
public String hello(String name);
@Stateless
public class Hello implements HelloRemote {
@Override
public String hello(String name) {
return "Hello "+name+"!!";
}- an Application Client project (containing the applet code):
public class ClientApplet extends JApplet {
public void init(){
try {
Context jndiContext = getInitialContext( );
HelloRemote server = (HelloRemote) jndiContext.lookup(HelloRemote.class.getName());
setContentPane(new JLabel(server.hello("Gerard")));
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
private Context getInitialContext() throws NamingException{
Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory");
props.setProperty("org.omg.CORBA.ORBInitialHost", "myhost");
props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
return new InitialContext(props);
}- a static web project (with a sample web page that contains the applet object the corresponding applet JAR file)
I tried to export the Application Client project as an "application client JAR", in the hope that the java EE libraries bundled with glassfish (listed as libraries of this project) would be packaged too.
No success, so now I'll try to copy all the JAR files (one by one) into the +\WebContent\+ folder of the Web Project, and add references to each of them in the archive="" attribute of the +<applet>+ HTML tag. Although this might work, I suspect that I am missing the good/easy way of doing it. Any suggestions?
Thanks in advance,
Gerard
Edited by: gsoldevila on May 6, 2009 7:09 AMAn Applet can communicate with an EJB via JNDI lookup but I would (personally) use an intermediate Servlet to handle this. Client to Servlet communication is http whereas to ejb is iiop - which might be blocked.
Injection only works in managed classes (EJB, Servlet, Listeners..) and an Application Client main class. So yes you could use an app client for handling resource injection.

Error while accessing a public method of applet from javascript.
Hi,
I am getting "Object doesn't support this property or method" error

Applets have strict security applied to them, and file i/o is one of the restrictions. There are ways around it, but for the moment I'd suggest you build a bridge and get over it.

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. -
Applet load times got you down?
Then vote for this RFE:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6346341
The whole discussion started here:
http://forum.java.sun.com/thread.jspa?threadID=678853&tstart=0
-DennisI have the same problem, and add this replay to motivate a clever person to solve this problem.
My situation is:
20 Applets (or so) on one page - they span exactly on Thread - if clicked. And if I reload the page they never work again - I have to restart the browser.
If I browse to the page with the applets I have complete browser crash in 3 of 4 cases. But the first time I visted the page after reboot of Linux (everything less don't help) all the applets work.
If I put only one Applet on a page and reload this page, then in a few lucky cases the Applet works a second time.
On windows everything is fine, so I don't think my
Applets are the problem.
On linux I tried several version of upto Mozilla 0.9.8
everytime the same (but 0.9.8 don't work at all with the plugin).
