IE 5.5 and Applets

Hi
I have done a quite a lot of java applications but not applets.
No trying to cover this I get problems with CLASSPATH I think.
When running my test applet with just one task in init() add a Jlist I get the NoClassFoundException javax.swing.JList what am I doing wrong how does this work ?

You should use this code for your Applet: (insteed of <applet ...>)
<OBJECT codetype="application/java" NAME="theName"
WIDTH = 450 HEIGHT = 250 classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<PARAM NAME = NAME VALUE = "theName" >
<PARAM NAME = CODE VALUE = "theName.class" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3.0">
<PARAM NAME = MAYSCRIPT VALUE = true >
<PARAM NAME="scriptable" VALUE="true">
<EMBED NAME="theName" MAYSCRIPT=true scriptable=true type="application/x-java-applet;version=1.2" java_CODE = "theName.class" WIDTH = 350 HEIGHT = 250 pluginspage="http://java.sun.com/products/plugin/1.2/plugin-install.html"></EMBED>
</OBJECT>
This will use JRE1.3. If this is not installed on the client maschine jre is installed automaticly.
MayScript and Scriptable are used to connect the Apllet via JavaScript.
I hope this could help.

Is it possible to run a website built in Java and applet from Safari browser in iPad

Is it possible to run a website built in Java and applet from Safari browser in iPad?

Java isn't supported on the iPad

JDev3.0's JSP and Applet works on NT but doesn't work on Win98, why?

JDeveloper3.0 works fine on WindowNT machine when I run JSP files and Applet, but at home the JDeveloper3.0 cannot trigger the browser to display the result on my Windows98 machine when I run the JSP files or Applet. Why? How can I make it works for me at home. Other tools, such as J++6.0 and JBuilder work with Applet on the same machine. Who can help me?

James,
The JDeveloper 3.0 design time environment is not supported on Windows98. Some functions might work under Win98 but they are not supported.
Sorry!

Regarding communication between JSF and applet.

Hi all,
I have to send a array of int value from JSF to the applet method and vice versa,
so how can I do that?
Is there any straight forward way is there?
Or I need to use javascript in between applet and JSF for communicating.
If this is case can give some links so that I can go through it.
What I need is, I have jsf table(grid) when I select a row from table, for the selected row I have to display selected row ID in applet and vice versa.
Any suggestion or links will be appreciated, thanks in advance.
Thanks
daya

thanks and sorry for late reply, let me go through the link,
i have tried with JavaScript, i got stuck, i need to call a JavaScript method for JSF component event listener. I searched in Google but no help regarding same.
Actually what I need is, I have JSF Component i.e. GridView(Table) and applet in a page. And for each row selection in GridView(table) I need to call a javascript method (with column value), and vice versa.
Can you give suggestion or any link so that can proceed further.
and i am able to communicate between applet which are included in the page
Thanks

Package and applet

I am reading about Zhiqun's Java Card book,
and I wonder about the relationship between a package and an applet.
Am I right in saying:
1. An applet comprises one or several packages
2. A package only belongs to one applet
3. One package is one group context
Hope to get your guidance.
B.R.
RuHE

Refers to your assertions,
Please help me..
Case 1
I have package A. Package A contains 2 class (A1 & A2 ) and 2 package (B and C).
Then, I make 2 applet, they are applet-B (for package B) and applet-C (for package C).
When simulationi in JCWDE, applet-B and applet-C have no problem. But, in CREF, applet throw exception and status word is 6443.
Case 2
When I try to include class A1 and A2 into package B and C, so package A is empy. Surprisingly, applet-B and applet-C can run in CREF and JCWDE. I don't know, what's wrong in case 1.
Can you give me explanation or explanation about problem in above...?

Appletviewer and applets

Hi!
I am using j2sdk 1.4.0 under linux. I have been creating an applet. The screen refresh is tied to a timer. However, the screen refresh gets very slow after 2 - 5 seconds after the applet has been started. If I move mouse in applets window, the refresh gets fast during that time.
The applet code is very simple: timer calls repaint method of the applet and applet's paint method just draws new picture to the screen using drawImage.
Anyone run into same problem? What could be wrong?
Thanks
Sammy

ok but whats the problem the fast refreshing??
if so then u have two options:
1)double buffering
2)if u dont need the re-paint let the java do it for u dont overide it

Can I use AWT and Applets in a J2EE project???

Hi,
I adore applets and the package AWT... And I would like to know if some way exists to integrate my applet with my application J2EE... I want to use these in the vision tier in a J2EE(EJB) project...
How can I make that my applet acts as an observing process of my model??? If the JVM will be informed on any alterations in the model will be the JVM of the server while my applet will be being executed for the JVM of browser...

Ary Junior

I have a J2EE application, for which I have a module which is used by system administrators. this module is completly written in Java swing.
and it does talk to my EJBs.
If you don't have a firewall in your application, then you can directly make your applications in awt, swing and applets talk to EJBs. if you do have a firewall, then just write a web-service wrapper over your EJBs and other J2EE components and use them from desktop applications.
It seems that you want to implement a kind of a applet based monitor application for your J2EE EJBs on the server. Applets cannot directly monitor your EJBs.
Create a new module which has a service which acts as an event listener on the server. each j2ee component on the server notify it if there is a change to them. this service, can then write the data realted to the modification on a socket which is continiously being read by the applet. So you can implement a kind of a monitor for J2ee apps with applets.
hope this helps.
regards,
Abhishek.
PS:How did you manage to adore the AWT ;-) ? I found that it sucks (good performance.. very poor lnf) ... java swing sucks too (very poor performance ... avaerage lnf).

Xml and applets

I'm trying to use Sax in an applet to read an xml file. My application works fine, but when I convert it to an applet, I get errors.
Does anybody know where I can get info and examples using Xml, Sax, and Applets? Any info would be helpful. Thanks.

Probably nothing to do with XML. You use it in an applet precisely as you would use it in an application. You are probably running into one of the usual applet problems. Of course, this is all guesswork without any idea of what errors you are actually having.

Unable to execute and applet

I'm new programmer in java. There are somme applet that run with appletwier
but witch do not run with Internet explorer and Netscape. I'm always getting
this error : 'Class not found'. I want to know all the steps to run and applet
using Netscape or Internet explorer.
I'm french speaking. Sorry if my english is poor.
Thank's for your answers.

I think you can't solve your problem.
The fact is that appletviewer supports the java classes you have installed with the sun's jdk... if you are using jdk 1.3.1, it uses the java libraries included in your installed distribution. IE virtual machine, instead, uses its own library, so you can't use in your applets classes like: swing, graphics2d, and so on...
I know that it's not a great help. Sorry!
However, if someone could tell us how to include these classes in our CABs/JARs... i think we are really happy! :-)
Ciao,
Paolo.

Looking for WEB HOST that I can do servlets and applets on

Hello everyone,
Does anyone know where I can buy web space that will allow me to run a servlet and applet from. I have been shopping today and I had difficutly finding one.

Hmm.... well duffymo. I have gone to a number of sites through Google looking for web hosting sites that support java and I must be picking all the wrong ones to look at because I have only found one in Fremont out of 25-30 that I have looked at.
I guess duffymo you can say what you want in a forum, but usually answering a question with a question isn't very helpful nor appreciated.

Problem with Image I/O and applet

I am having trouble using Image I/O to load a PNG image in an applet. I am just using a very basic applet that simply loads the image from a URL and that's it, and the exception I get is -
java.lang.SecurityException: Unable to create temporary file
at java.io.File.checkAndCreate(File.java:1294)
at java.io.File.createTempFile(File.java:1385)
The simple applet is as follows -
import java.awt.image.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
import javax.imageio.ImageIO;
public class CheckImageApplet extends JApplet
public BufferedImage bi = null;
public void init()
URL url = null;
BufferedImage bi = null;
try
url = new URL( "http://localhost/CheckImageSystem/checkimages/backGS.png" );
catch ( MalformedURLException mfue )
try
bi = ImageIO.read( url );
catch ( IOException ioe )
Any thoughts on this exception would be appreciated

It seems the line
bi = ImageIO.read( url );
fails. Can't see anything else. Perhaps this method needs to create a temp image for some reason, and tries to do this at the local harddrive (not allowed). Use getImage(URL, String); instead. ImageIO isn't intended for applets, I think, so you should use the applet methods.

Problem with JPanel, CardLayout and Applets

Hello All,
I have a JPanel with a CardLayout as layout manager. In this JPanel i'm gonna show a few applets.
My problem is when i'm showing an applet for second time and try to click a button it does nothing... I think the action method is not called again...
How can i solve this?
Thanks in advance ; )

Here is a few parts of my code...
public class InitAll{
JPanel cards = new JPanel( new CardLayout() );
JComboBox selector = new JComboBox();
Object objetosV[][] ={
     {"Ventas",venta.class},
     {"Compras",compras.class}, //These are applets.
     {"Traspasos",traspasos.class},
     {"Facturas",factura.class},
public void load( Applet app ){
cards.removeAll();
selector.removeAll();
cards.add( "Entrada", app );
selector.addItem( "Entrada" );
for ( int i=0; i < objetosV.length; i++ ){
     selector.addItem( (String)objetosV[0] );
     Applet temp=createPanel( ( Class ) objetosV[i][1] );
     temp.setSize( 800,750 );
     cards.add( ( String ) objetosV[i][0], temp );
public void itemStateChanged(ItemEvent e) {
((CardLayout)cards.getLayout()).show(cards, selector.getSelectedItem().toString() );
Applet tmp = (Applet)cards.getComponent(selector.getSelectedIndex() );
tmp.start();
After i show for second time an Applet and select a button from it. the button does nothing...
Thanks...

Communication between JApplet and Applet on the same web page

Hi Freinds
I have a JSP page containing two applets as follows :-
<jsp:plugin type="applet" code="TreePageJavaClass.class" codebase="/MYOA" width="200" height="300" name="Applet1">
</jsp:plugin>
<jsp:plugin type="applet" code="TreePageJavaClass2.class" codebase="/MYOA" name="Applet2" width="200" height="300">
</jsp:plugin>
First applet extends JApplet class and has a tree constructed using swing.
Second applet extends Applet class.
Now I want to call a method in second applet on selecting a particular tree node on first applet. I can call method on second applet from first applet when both extends Applet class (not JApplet)
So please tell me what's the problem here and how it can be solved.
Thanks

Self Signing and Applets

I have spent hours reading over the Signed Applets forum and Sun applet security training pages. There seems to be so much confusion in this area that the use and proliferation of Java Applets must be suffering.
As the usual underfunded developer, I am not able to buy a certificate before proving the concept. Therefore, I am relegated to using self signed applets to demonstrate the use of signed applets and the power they have. This would also be the case for students of Java applets, of which I am also one.
I have tried the sample applets in the Sun security training. They in fact write the file to my system, but they also display a security error as well.
The Sun training indicates that I should be using a policy file with the security and that when my applet is run by another user, that user must also manually update their policy file, using keytool, before running the applet. If this is true, I see no use for Java Applets that work outside of the sandbox confines. There must be a better way to use applets that require security.
I have also read Irene's 10 steps and numerous comments about them. They seem to work fine until I get to step 10. If I am using a self signed applet, why should the user of the applet have to click on a HREF to load the certificate into the keystore? Why shouldn't the user be prompted to trust the self signed certificate, just like a certificate obtained from a CA?
I have tried to develop a batch file (Windows NT 4.0) to illustrate the signing process, but I have been unsuccessful. I have listed the output from it below followed by the batch file itself. Would someone please indicate what would make this batch file work? If possible, I would like it to work for both IE 5.5 and Netscape 4.06; especially ie 5.5.

HostApp and Applet in the same project space?!

Hello,
I am using EclipseJCDE for the Applet side and jCardSim for the host application side.
I wonder if I setup 2 packages, one for each side.
As you know, I can't include Java SE (jre7) for the Applet.
When I encompass both applications in one project space, the host application side cannot find certain standard functions
But when I separate them into 2 project spaces, how do I make them talk?
Thanks
Jack
