Applet using JXTA

Hi, Can i use JXTA from a signed appleted to transfer a file to another applet. And is JXTA components provided in J2SE.
Thanks!

I wrote an applet using swing components that is running fine in applet viewer forgot to mention... you run appletviewer using .html file in your local computer, rite? so ARCHIVE = "oddsApplet.jar" means your jar in the current/same folder with the .html. your appletviewer can find it and start it.
but when I try to use it in my browser it won't work.what url you are open? http://www.geocities.com/bla bla bla... or file://C:/bla bla bla... i think it will work with url=file://c:/ bla bla bla...
I took the .jar file from the "NetBeansTM IDE 4.0 " and put that on my geocites web page in the same folder as the html file.ARCHIVE = "./oddsApplet.jar"

Problem in loading an applet using JRE 1.5

Hi,
I have an applet which is working fine under JRE 1.4, but the same applet failing to load by using JRE 1.5
Problem Description:
1. The images in the applet fails to load using JRE 1.5
2. The Username and Password text box are also failing to initialize.
Can anyone help me out in this.
Is there any code changes required ?

I wonder if you have the same problem as me... Maybe we can find a solution for us both, no need for me to open a new thread for this topic then...
I wrote an applet using Swing and compiled it using JavaSDK 1.4.x. I also installed the 1.4.x JRE for both of my test browsers. In Mozilla 1.1 the applet displays properly all the time. In IE6 SP1 it sometimes works as intended but sometimes the applet simply stops working, as per my Java Console somewhere after invoking the "start" method. Parts of the applet simply become gray and when I resize it - I have a JFrame in my applet - the whole JFrame becomes gray and does not respond to input nor it redraws itself. Shutting down IE does not close the JFrame(although the java console reports normal program termination and cleanup) and the only way to close it is through the task manager. I am using Windows 98SE btw.
Does it sound similiar to your problem? It happens ONLY with IE, not with Mozilla. Anybody has an idea on what it could be? I doubt there's an error in my code...

Html file to run an Applet using swings in 1.4.1 or 1.3.1

Can anyone send me an html document to launch the applet in a browser. I have very basic html, but I need one that uses the appropriate plug-in and that has parameters such as height, width, etc. My applet uses tabbed panes, dialog boxes and comboboxes. It works well with appletviewer, but does not work in IE or Netscape.
Thank you for your help
here is what I am using which does does show anything but a grey screen

Japanese text display problems in applet using plugin

Hi,
We've been beating our heads against the wall on this one for quite some time, so any help would be greatly appreciated.
Our product uses a third party applet (Kavachart from Visual Engineering) to display graphical statistics from our database. We are currently localizing our product to support english and japanese. With Japanese enabled, all pages use euc-jp encoding. The problem we are running into is in the display of japanese text inside this applet in IE 5 and NS 4.7x when using the java plugin (1.3 or 1.4). If the default jre of the browsers are used, the text in the applet renders fine.
On a suggestion from the supprot folks at Visual Engineering, I modified our code to set the defaultFont parameter on the applet to "serif, 14, 1". With this set, the text in the applet renders ok in IE, but NS on windows and unix is still broken. Given that we are doing all these tests on machines running a native japanese OS, it's not even clear to me why setting the defaultFont should even be required, but at this point, I'll take anything :-)
Has anyone else run into this and either solved it or proven that a solution is not feasible? I'm at my wits end here....
Thanks in advance,
Mark Evangelisto

If you are using different java plugin, you need to install the international version of the JRE; otherwise, some characters may not be able to display correctly since some of the properties files are missing.
As for Visual Engineering's suggestion. I don't know why they tell you to set the default font on the applet because it may cause the browser to use the font specified. Your applet works on IE because it will try to use the best font to match the web page's content. For NS anything less then 6.0 (technology based on Mozilla), they never display web page correctly especially if you did what VE suggest.
If you are running the applet on the native langauge OS with the international version of the JRE installed, the applet should display correctly without setting the default font. If it is not the native langauge OS, first you need to install the international version of the JRE and have the fonts that are able to display the language the applet use.

Writing new HTML to a page from an applet using LiveConnect, 1.3.1 Plug-i

Has anyone been able to successfully replace a page with an applet with the dynamically generated HTML from an applet using LiveConnect and Plugin 1.3.1 in Netscape 6.2 or IE?
The following works fine without plugin or with 1.4.0 beta3 plugin.
Here is the code that I use without plugin:
JSObject windowObject = JSObject.getWindow(this);
JSObject documentObject = (JSObject) windowObject.getMember("document");
documentObject.call("close",null);
documentObject.call("open",null);
String anArray1[] = {null};
anArray1[0] ="some HTML here";
documentObject.call("write", anArray1);
documentObject.call("close",null);
Here is the code that I use with 1.4.0 plugin:
JSObject windowObject = JSObject.getWindow(this);
JSObject documentObject = (JSObject) windowObject.getMember("document");
String anArray1[] = {null};
anArray1[0] ="some HTML here";
documentObject.call("write", anArray1);
When I try to use anyone of the above using plugin 1.3.1, the browser either hangs or plugin generates runtime error. What is the correct way of writing to a document object? Or what is the way that works for 1.3.1 plugin?

Hi,
I am doing this in my applet to replace the page containing the applet with the new content. I tested that extensively with Netscape 4.7 and IE 5.5+. Definitely works if you are using Java Plug-In 1.3.1_02. Does not work well in Netscape 6.2.
    protected void setPageContent(final String newContent) {
        final JSObject window = JSObject.getWindow(this);
        final JSObject document = (JSObject) window.getMember("document");
        new Thread( new Runnable() {
                        public void run() {
                            document.call("clear", null);
                            document.call("write", new String[]{newContent});
                            try {
                                          document.call("close", null);
                               } catch (JSException ignored) {
                    } ).start();

Please give me an exemple of an applet using a swing object.

Please give me an exemple of an applet using a swing object.thank you.

My problen is that the swing object do not appear in
my applet. They appear only if i invoque the repaint
methode.use JApplet, since awt components are heavyweight, and swing components are lightwieght, then your swing components get over painted with aplets background or something.
anyhow, in your applet you may create JFrame, that would be swing component and if you set it visible, then it will be even visible.
they say that mixing swing and awt is not good idea, especially when you don't know what you're doing (which might be true in your case)
so try to migrate your app from AWT based stuff to SWING based stuff, or write your own AWT components that do the job whih you needed swing component for at the first place.
but if you need to mix awt and swing, then i thing that you should not paint the fole area of applet in applets paint method -- but here i'm not sure, never mixed 'em.
so you might try to create an applet which paint() method you leave empty and to which you add some JComponent*.
and see what happens, maybe this JComponent will be visible.
* -- JComponent is most likely just gray, you might want to add some subclass of it -- JButton, JTextField, JSomethingElse.

Can you please tell me how can i change the parameter of Applet using Aspec

Respect Members
Can we apply Aspectwerkz on Applet? In our project we have to
change the method parameters before its execution(Around Advice) , can we do this in applet using Aspectwerkz?
Can you please tell me how can i change the parameter of Applet using Aspectwerkz or AspectJ ?
I did it by for Java Application using the AspectJ And Aspectwerkz But not able to do for Applet.
For Applet I Am setting the parameter in JAVA plug in for Aspectwerkz e.g. -Xdebug -Xrunaspectwerkz -Xbootclasspath & path for xml file in which pointcut is defined.
If you any Friend working on it or any author who might be helpfull for me please Forward this mail to him/her
THANKs in Advance

hello rodale, what you're seeing is probably a side effect of firefox not being able to save certain preferences into its profile folder.
go to ''firefox > help > troubleshooting information'', click on ''profile folder/show folder'' and close all firefox windows afterwards. a windows explorer window should open up - in there delete the file named '''user.js'''.
in case this didn't solve the issue yet please also refer to [[How to fix preferences that won't save]].

Using my own machine (connected to a network), I tried to test this one out by setting mine as the server and also the client. I did the following:
1. Compile the source code.
2. Use rmic to generate the skeletons and/or stubs from the ChatCallbackImplementation and ChatServerImplementation.
3. Start the rmiregistry with no CLASSPATH
4. Start the server successfully.
5. Start the applet using the AppletViewer command.
It worked fined.
The problem is when I ran the applet using the browser, IE explorer, the dialog boxes, frame and buttons did appear. I was able to do the part of logging on. But after that, the applet seemed to have hang. No message appeared that says I'm connected (which appeared using the appletviewer). I clicked the send button. No response.
I double-checked my classpath. I did have my classpath set correctly. I'm still trying to figure out the problem. Up to now, I don't have any clue what it is.
I will appreciate much if someone can help me figure what's could have possibly been wrong ....
Thanks a lot ...

Hi Domingo,
I had a similar problem running applet/rmi with IE.
Looking in IE..view..JavaConsole error messages my applet was unable to find java.rmi.* classes.
I checked over java classes in msJVM, they're not present.
( WinZip C:\WINDOWS\JAVA\Packages\9rl3f9ft.zip and others from msVM installed )
( do not contain the java.rmi.* packages )
I have downloaded and installed the latest msJVM for IE5. ( I think its included in later versions)
@http://www.objectweb.org/rmijdbc/RJfaq.html I found ref to rmi.zip download to provide
these classes. I couldn't get the classes from the site but I managed to find a ref to IBM
site @http://alphaworks.ibm.com/aw.nsf/download/rmi which had similar download.
The download however didn't solve my problems. I was unable to install rmi.zip with
RmiPatch.exe install.
I solved this by extracting the class files from rmi.zip and installing them at C:\WINDOWS\JAVA\trustlib ( msJVM installation trusted classes lib defined in
registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM\TrustedLibsDirectory )
This solved the problem. My rmi/applet worked.
Hope this helps you.

Memory leak with 1.6.0_07 in applet using Swing

Java Plug-in 1.6.0_07
Using JRE version 1.6.0_07 Java HotSpot(TM) Client VM
Windows XP - SP2
I have a commercial application that has developed a memory leak with the introduction of the latest plugin. The applets chew up memory and eventually freeze. They did not before. Using jvisualm I see a build up of native arrays, primarily int[][] and char[]. I'm still investigating. Anyone have a similar experience?
The Applet uses a swing interface, uses buffered images and swing timers, and regularly performs http connections to the server which result in actions via the SwingUtil.invokeLater() method.

I am Using Internet Explorer Browser Version 6.0.Huge security hole.
Its not throwing Error / Exception Wrap a try/catch at the highest level possible.
Catch 'Throwable'. And log/display it somewhere.

Displaying java applet using webseal authentication

Hi all,
i'm facing a problem about displaying Java applet using Webseal junction for accessing an application Server based on Websphere.
I've defined a webseal ACL on accessing a http url that contains link to Java applet: after webseal authentication, the homepage is loaded; in the home page are presented links to java applet, but when I try to load these applets, it seems not working.
If I load the same applets without Webseal authentication, it seems working.
Is there any sort of configuration to make for applet regarding Webseal?
Thanks in advance
Danilo

Problem with access JSF applet using javascript

Can someone help me!
I'm using a applet in jsf page, and i'm trying to access this applet using a javascript.
Here is the applet code
<jsp:plugin code="DoAction.class" codebase="." height="400" hspace="10" jreversion="1.5" type="applet" vspace="50" width="100" name="myApp"/>

I develop an applet using JMF for playing .mov. It works fine, and the applet starts normally. Even my applet works fine from other computers in our LAN (The applet runs ok without JMF). But only on one PC it doesn't work and I get the following message

Thanks for your time

It started to work but I had to install fobs4jmf on the client computer.
And put .dll to windows/system33 directory. But how can I play video using applet in browser without installing any software on the client machine?

I wonder if you have the same problem as me... Maybe we can find a solution for us both, no need for me to open a new thread for this topic then...
I wrote an applet using Swing and compiled it using JavaSDK 1.4.x. I also installed the 1.4.x JRE for both of my test browsers. In Mozilla 1.1 the applet displays properly all the time. In IE6 SP1 it sometimes works as intended but sometimes the applet simply stops working, as per my Java Console somewhere after invoking the "start" method. Parts of the applet simply become gray and when I resize it - I have a JFrame in my applet - the whole JFrame becomes gray and does not respond to input nor it redraws itself. Shutting down IE does not close the JFrame(although the java console reports normal program termination and cleanup) and the only way to close it is through the task manager. I am using Windows 98SE btw.
Does it sound similiar to your problem? It happens ONLY with IE, not with Mozilla. Anybody has an idea on what it could be? I doubt there's an error in my code...

Java applet using the Swing API

write a Java applet using the Swing API to manage a PC repair shop. When a PC is brought in for repair, a member of staff will use this applet to log it into the system as a repair job. They will also be able to use the applet to manage the job e.g. allocate a person to carry out the repair and enter costs.
You must not use a tool such as JBuilder to generate Java code. If you use code from elsewhere e.g. a text book, you must highlight the code and state the reference clearly and include a photocopy of the relevant pages from the text book or other source.
You should hard-code some initial data into your applet. You should not store any data in a file or database.
Level of functionality you should attempt to implement:
Level 1 � Your applet should:
a.     As a minimum, your program should store (in memory) at least 10 repair jobs. For each repair job, you need to store:
�     The name and phone number of the customer bringing the PC in for repair;
�     A brief textual description of the problem;
�     Whether the PC is under warranty or not.
b.     Your program must allocate and display a unique number for the job once it is accepted.
c.     The user must be able to view the details of jobs. They should be able to select either:
�     All the jobs in the system; or
�     Jobs being carried out under warranty.
Level 2 � Your applet must meet the requirements for level 1. In addition it should:
a.     You should carry out appropriate validation checks on input data e.g. the phone number contains all digits.
b.     System should cope with an unlimited number of jobs.
c.     The user should be able to select a job and then allocate a repairer to that job.
d.     The user should be able to display a list of jobs for each repairer.
Level 3 - Your applet must meet the requirements for level 1 and 2. In addition it should allow the user to:
a.     Select a job and input the cost of repair for:
�     the number of hours labour;
�     parts.
b.     Select a job and present the user with a cost for the labour (hard code an hourly labour cost) and parts, plus a total for that job. For jobs under warranty the total will be zero, however the cost of labour and parts will be shown.
c.     Be able to inform the business of the total expected income from the all the jobs in the system that are not under warranty.
Level 4 � Your applet must meet the requirements for level 1 to 3. In addition:
a.     The user should be able to enter a job priority which can be identified as high, medium or low.
b.     Each repairer should be able to view a list of their jobs in order of priority.

Done, what next ?

Swing Applet using JSObject.getWindow can not use javaFX

I have a Swing Applet that I will like to extend with some javaFX 2.0.3 abilities.
The Swing Applet uses the JSObject.getWindow method which is part of plugin.jar.
When I add javaFX I am not able to compile my application as jfxrt.jar also has a JSObject implementation, but without the getWindow method.
Is there any way I can extend my existing applet with javaFX?

The order of dependencies is probably not the issue here but rather that there are two classes with the same fully qualified name which causes problems if the signatures differ
