Applet in html page

Sorry I'm geginner in java and not so good in english !
My question:
when i compile an applet classe for the first time and use the applet in a web page it works correctly. but when I modify the Applet class and compile it again and use it in the same page , I saw no changes .
Also same page same classname.
It look like if the browser do not close or destroy the class .
when I restart the PC and load the page again , the modif take place correctly .
Please , i need your help

It's because your browser is caching the applet (storing locally to save download time).
You should be able to force a reload, by holding down shift when you click reload.

Display applet within html page

hi there,
i created an applet using the <embed> tag instead of the old <applet> tag. when i call the html page the applet is displayed in a separate popup. i want the applet to run on the html page - no popup.
how do i achieve this?
thanks for your replies!
koen

I think your tag isn't quite correct, try this one :
<HTML>
<body>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" width="600" height="300" align="middle">
<PARAM NAME="code" VALUE="KoenMain">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
     <COMMENT>
     <EMBED width="600" height="300" type="application/x-java-applet;version=1.3" code="KoenMain">
     <NOEMBED>
</COMMENT>
     This page requires a Sun Java Plugin 1.3
     </NOEMBED>
     </EMBED>
</OBJECT>
</body>
</HTML>
I tried this code (replacing KoenMain by a class of mine) and it works fine, with IE and Netscape, don't forget to specifie size (width, height) in your "EMBED" tag.
If it doesn't work for you, I think the problem comes directly from your applet code.

Failed to load applet in HTML page

Hi,
I cannot load my applet under IE9+, Chrome (v28). The applet is signed because it access to file resources.

Is there something wrong in this code?
Thanks.

Applets run client side - which means the relevant class files need to be downloaded to the client.
Anything under the WEB-INF directory is not directly accessible by the client. Nothing under WEB-INF can be downloaded.
ergo, specifying the WEB-INF directory as part of your applet codebase is a bad idea.
I would suggest try copying the applet classes from under WEB-INF to some other place in your application.
Also, you should probably specify the full class name of your Applet in the plugin tag.
<%@ page import="com.util.MyApplet" %>
<jsp:plugin type="applet" code="com.util.MyApplet" codebase="/classes" width="250" height="100" jreversion="1.6">
     <jsp:fallback>
          <B>Unable to start plugin!</B>
     </jsp:fallback>
</jsp:plugin>cheers,

Open a html page from an applet

Hi,
I would like to open, from an applet, an HTML page in a new window with a specific width an eight.
Who can help me ?

Here is an example of applet to javascript with liveconnect:
http://www.narhari.com/java/applet2javascript/
You can use the send(String) method from the sample applet to send something like:
window.open('xyz.html','myPopup','width=200,height=200');in order to open a window with specific dimensions
of course you can also build HTML in your applet and use send() + some javascript to render it.

Replace HTML page with an applet

Hello to everybody!
I created a servlet who can manage file upload from an HTML page.
Now I want to replace that HTML page with an applet.
I know that I need to use multipart/form-data , but I have no experience with applet.
HTML page code is:
<html>
<head><title>Upload</title></head>
<body>
<FORM ACTION="http://localhost:8080/examples/servlets/servlet/UploadTest" ENCTYPE="multipart/form-data" METHOD=POST>
What is your name? <INPUT TYPE=TEXT NAME=submitter> <BR>
Which file do you want to upload? <INPUT TYPE=FILE NAME=file> <BR>
<INPUT TYPE=SUBMIT>
</FORM>
</body>
</html>
Any help for "translating" this html page into an applet?
Applet will send, like html page, a string and a file.
Thanks in advance, Liuk

If you use something like Apache Http Client you dont have to do any low level implementations.
Also if you are the one who is writing both servlet and applet you dot have to stick to standerd formats. you can develop your own format and write both servlet and applet to handle it. that kind of thing can be done easily even with URLConnection. But if you plan to send large files then URLConnection may not be the right option becouse I have seen many complaining that URLConnection gives OutOfMemoryErrors when uploading large amounts of data.

Referencing a "locally installed" Java applet from a server-based HTML page

How does one reference a "locally installed" Java applet from a server-based HTML page (i.e. via the applet, object, or embed tags)? I have seen references in documentation that this is possible, but I have not seen any examples. I have tried a few things, but nothing seems to be working.
Some background...
I'm working on a web site that aggregates Internet video. For many users, I would like the site to work "without" requiring Java to be installed (or any prompts, etc.). This version of the site allows users to stream videos directly over the Internet and does not require any sort of access to the local system.
However, in addition, I have a download manager that can be installed on the local system. Currently, it's a Windows-based "service" that is always running in the background, downloading files, etc. (with plans to later support other OSes).
My dilemma is trying to communicate between my web site running in the local browser (executing JavaScript code) and the download manager. I call this component the "gateway". I need the gateway to be able to do the following:
1) Pass user credentials from the web browser UI to the download manager (so it can communicate with my servers).
2) Check the status of downloaded videos
3) Launch a local media player (such as Windows Media, QuickTime, etc.) (or perhaps tell the download manager to launch the media player).
Under Windows XP, I have an ActiveX control that can do these things. It communicates with the download manager via reading/writing to a shared XML configuration file.
Unfortunately, under Vista and IE7 Protected Mode, ActiveX controls have become very restricted and my gateway no longer works. As such, I am looking at using Java for the gateway (also giving me the additional benefits of supporting additional browsers and OSes).
From my understanding, I believe I can created a "face-less" Java applet, whose methods can be called from JavaScript. Ideally, I'm thinking I could install the applet onto the local system at the same time the download manager is installed. This would give the applet the security permissions it needs to communicate with the download manager.
Thanks for any help and suggestions!

Hi,
Put the .jar file and the .class file in the path mentioned in one of the aliases in the plsql.conf file like /images or create
a seperate directory and create an alias like /applets "path" in the plsql.conf file.
<html>
<body>
<applet code=com.chartapplet.chart.BarChartApplet
codebase=/applets/
archive=/applets/chart.jar width=300 height=200>
<param name=background value="white">
</body>
</html>
Hope this helps.
Thanks,

How to display an image on the HTML page by using applet

Dear friends,
I am now writing an java applet, I want to display an image on the HTML page, and tried the following commands:
{color:#ff00ff}{color:#000000}Image map; //put in the class definition
map=getImage(getCodeBase(),"hhh.gif"); //put in the function of init()
g.drawImage(map,0,300,this); //put in the function of paint(){color}
{color}
However, when I run it, the image wasn't displayed at all.
I hope who guys ever come across this problem could help me to solve it. Thank you in advance!
Hawaii

Hi,
I am no expert on Images
but
from personal exp.
are you sure that map actually contains the image?
try using
ImageIcon ii = ImageIcon(String name);
map = ii.getImage();I saw a tutorial on images i think on sun
where they use ImageIcon to load the image

Java Applet in a HTML page: failing with PLS-00306: wrong number of args

We are trying to use a Java Applet in a HTML page. as our system needs to be able to retrieve a predefined set of data from a third party system that uses Dynamic Data Exchange Protocol (DDE) and are encountering errors from APEX and in IE itself.
We are using JavaDde from www.nevaobject.com that enables our Java applet to interact with Windows applications (Third Party System) using DDE.
This functionality is currently used in our Web Form 6i application and we are trying to use the same in the new ApEx application.
We are using ApEx version : 2.1 and actually aer encountering 2 problems:
Problem 1: ApEx failing with PLS-00306: wrong number or types of arguments in call to 'ACCEPT'
Problem 2: IE crashes if Applet used in a complex page with several regions (1 Context, 4 Report Regions, 2 level Tabs, Links)
This problem does not occur in the page where there is only applet and one region. In the case of complex page the IE crashes if the page is reloaded
Test scenario:
1- Create a simple page with the HTML region.
2- Define the Source of the above region as follows
<OBJECT CLASSID="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
CODEBASE="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#version=1,4,0,0"
WIDTH="1"
HEIGHT="1"
ID="simpleApplet"
NAME="simpleApplet">
<PARAM NAME="code" VALUE="simpleApplet.class" >
<PARAM NAME="archive" VALUE="simpleApplet.jar" />
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.4">
</OBJECT>
3- Create a simple Java applet "simpleApplet" - for the test its enough if the applet will have just the init method printing out the mesage to the console
4- Create a Submit Button (not redirect) in Region Header and create unconditional (do not set When Button Pressed property) Page Branch to navigate to another page (the page without the applet)
6- Run the page and Submit -
The error below is returned by the engine:
In our case our applet is called ddeApplet - I do not know why is ApEx passing the Applet's ID down to the wwv_flow.accept method as a parameter

It looks like whatever HTML you're including on your page is creating HTML input form elements inside the HTML form "wwv_flow". This form is posted to wwv_flow.accept, and of course, the PL/SQL procedure wwv_flow.accept doesn't know anything these additional arguments/form elements you're attempting to POST.

How to show a html page in a swing applet -- URGENT!!!

Hi All,
I'm trying to show a html page inside a swing applet... is it possible to do that?? if so is there any built-in classes available for that?? If anyone have some examples, plz help me with that....
Thanks,
Ragu

i havent tested.. but this should work. i am no expert on these either, just to give you an example.. :-)
JEditorPane ePane = new JEditorPane();
HTMLEditorKit html = new HTMLEditorKit();
ePane.setEditorKit(html);
HTMLDocument htmld = new HTMLDocument();
try{
URL url = new URL("http://hcs.harvard.edu/~undercon/");
InputStream ins = url.openStream();
ePane.setDocument(htmld);
html.read(ins,htmld, 0);
this.getContentPane().add(new JScrollPane(ePane),BorderLayout.CENTER);
catch(Exception e)
e.printStackTrace();
}

Call an applet in other page html with javascript

Hi
I found many exemples with javascript, to call applet method in the same html page, but never cross pages
There is a way to call with javascript an applet in other window/page?
Thanks

By other WORKSPACE do you mean another location (as defined in dads.conf)?<br><br>Either way, you just have to make the url relative or just hard code the entire path. If location 1 is pls/htmldb and location 2 is pls/htmldb_two then all you need to do is:<br><br>
owa_util.redirect_url( '/pls/htmldb_two/f?p=TLL:3:&SESSION.::::F119_TAB_CONDITION:1');<br>
that is if I understood your question correctly...<br><br>

How do You set -noverify in an HTML page that calls an applet

I have an applet which runs fine from inside JBuilder when I specify a
-noverify switch in the debugger. (java -noverify myapplet.class)
Without this switch, I get a verification exception.
So I need to specify the -noverify switch from inside a webpage so that when the client runs it, he does not get the same exception.
The question is how do you pass -noverify to JVM from an HTML page that uses <applet> tag and javascript?
Thanks

Odd, because I work on an applet that gets built with 1.4. We have 30,000+ clients who use it every day, and I'm sure we don't tell them about setting -noverify switches in their plug-in control panel, and we don't (cuz we can't) set it in the applet (object/embed, actually) tag.
Of course, I suppose it could be a backwards compatibility issue going from compiling in newer version than it's run in.

I cannot get an applet to run in an html page through jdeveloper 10g

I can run applets ok that i bring down from the web so i know the browser will support applets. But they will not work when i try to run a html page with an applet through jdeveloper. When I use the tool to create a page that will run an applet i get the message "This browser does not support Applets." appearing even though
I know the pages does support applets. What am i doing wrong?
cheers;

Nope...I create an applet and then use the tool to create an html page i get the following page...

How to open an Applet from a text link in a HTML Page

Hi There
How to open an Applet from a text link
in a HTML page
For example I have a HyperLink "Open Applet"
When a user clicks that link i want to open a
Applet in a AWT Window.
How can i do this
Will any one help me?
-Ramya

u can use javascript for that
<SCRIPT language="javascript">
function loadAppNow() {
document.write("<APPLET ......></APPLET>")
</SCRIPT>
LoadApplet
this will overwrite the applet on current window
There are many good ways other than document.write to open in same window. I don't remember the syntax right now.
Plz. refer to javascript tutorial for that.
even you can insert the applet while retaining previous contents. its quite easy actually.
regards....bhart
