HTML Page in Applet

I am trying to figure out how to get HTML code to display in a panel of an Applet. Does anyone have any ideas. I have tomcat displaying a HTML file but I need to know how to display it inside of the applet.
Can it be in the same application. I don't want to unload the applet. I would like to see it inside of the applet.
Thanks
Eric

Yeah, bookmark this page! http://java.sun.com/j2se/1.4/docs/api/index.html
This is where I go first when I have questions. I wish more people in these forums would check the javadoc more often :).
Just search in the left frame for JEditorPane and click it to get its documentation. It's not too hard to configure it for html. If it doesn't you could try http://www.javaworld.com

Any Way to display HTML pages on Applet

Hi All,
Is there any way to show web pages on Applet?
Is it possible ?

I am not aware of a simple way to display HTML in an applet. However, I have used the JEditorPane to display HTML documents. Handling links, etc. with this component requires some effort. Also requires Swing.
Have you considered using the applet to display a page on the browser. (i.e. getAppletContext().showDocument(URL, [frame name]))? Just an idea.
Good luck.

HTML Page with Applet in JEditorPane

Hi,
I have a JEditorPane in which i want to show a HTML page which has an Applet embedded in it. Is there anyway that I can do this as if I just give the URL of the HTML file it gives me a text field with applet tag written in it.
Or is there any other way that I can embed an Applet in my application in one of Swing components.
Thanks in advance,

Update:
You may want to extend HTMLEditorKit:
public class MyHTMLEditorKit extends HTMLEditorKit() {
    static ViewFactory viewFac = new HTMLFactory(){
       public View create(Element el) {
          if(el.getName().equalsIgnoreCase("APPLET")) {
              Applet app = ...; // create applet from other attributes
          else return super.create(el);
}Check this out. I don't know whether applet elements are included in the parsed document; nevertheless, check it out.

Any "free" classes out there to display an HTML page within Applet?

I'm not using Swing - so I'd prefer a basic HTML parser and renderer. I just want to make a simple help system for my applet -
Any ideas?

Yes JLabel supports HTML, e.g.
public static void showHelp()
   JFrame frame = new JFrame();
   JLabel helpLabel = new JLabel();
   JLabel.setText("<HTML>This is a <b>help</b> file.</HTML>");
   frame.getContentPane().add(helpLabel);
   frame.setBounds(0,0,200,200);
   frame.setVisible(true);
}

Display applet within html page

how do i achieve this?
thanks for your replies!

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.

Html page hides jframe

I developed an application using jdk 1.2.2. Rcently we updated to 1.5.1. The html page that calls the applet opens. You can see the applet flash, but the html page then hides the applet. If you minimize the html page the applet shows, but I really don't want users to have to do this. I have tried using the visble(), toFront(),show(), and requestFocus() methods but to no avail. I have changed the code on the html page to reflect going after the 1.5.1jdk. Thanks for any help you can offer.

Annoying screen appears everytime when calling another html page.

i deployed my form application onto the web successfully. But
there's one screen (Oracle Developer Server R6i) appearing every
time I go to another page.
For example: I have 2 forms A and B, each has its own html page
containing Applet tab. The application starts from A.html, and
A will call B.html. This oracle screen displays all the time
when i click back or forward.
How can I eliminate it?

Thank you for your answer.
The reasons I want to use web.show_document are:
Firstly I don't know how to close the calling form when open the
called form. The code works in client/server env, but it just
hangs there on the web.
Secondly, I hope to use the web back button to return to the
previous form.
Is there anyway i can do to eliminate the splash screen and
function well?
My guess is that you are talking about the splash screen that
you can disable with a paramter in the HTML file.
But this will not happen if you use normal CALL_FORM or
OPEN_FORM buil-in in forms to activate one form from the other.
Don't use web.show_document to open a new form it will only work
slower that way.

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.

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.

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.
