LookAndFeel in Applets

Hi,
we are writing an applet. To set the applets LookAndFeel we implemented the following code:
static {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
catch (Exception e) {
If we use this applet in a browser on Windows, the applets LookAndFeel is switched to the Windows-LookAndFeel. Perfect.
But...
If we use the browsers Back-Button and then the Forward-Button, the LookAndFeel will switch to Metal???
What's going wrong ?
Is there a way to change the above code to make this work ?
Thanks for help

only things that works:
putting this in the start() method
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
SwingUtilities.updateComponentTreeUI(this);
} catch (Exception e) {
e.printStackTrace();
}

How to change "window LookAndFeel" of applet?

hi~~
I have changed the LookAndFeel of Applet with following code:
try{
UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
SwingUtilities.updateComponentTreeUI(frame);
catch(Exception e){}
,but WindowsLookAndFeel seem not to be shown when it run on IE.
why no any change?

I assume this is a windows box, and that you've tested that that look and feel exists already.
My guess would then be that Windows has an option, somewhere, that tells windows not to
use the LAF. It's labeled as "Do not decorate buttons", or something equally odd. Unfortunately,
I have no idea whatsoever where the option is.

LookAndFeel in Applet

How do i set the LookAndFeel in an Applet?
i know that for an app i do UIManager.setLookAndFeel(); but ive no idea how to do it for applet
Thank you
Ivo

It's the same thing as it would be in an application. Of course, you must mean JApplet. Here's a simple example:
import javax.swing.*;
public class MyApplet extends JApplet
    public void init()
        try
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
        } catch(Exception e) {}
        JButton button = new JButton("Hello");
        getContentPane().add(button);
}

LookAndFeel issue reloading an Applet in a Web page

Hey all,
I have an Applet that runs on a web page (loaded by servlets and JSP's using Tomcat 3.2.1 and Apache). I created my own LookAndFeel class and have a static function in the applet that sets the LookAndFeel to my new class. Everything works fine when the Applet is first loaded. However, when you exit the applet and then reload it, the custom LookAndFeel is gone and all I get is the default Metal. If I load the applet with appletviewer, I can reload it as much as I want and it always loads my LookAndFeel class.
The static function is as follows
/** Static initializer to set the LookAndFeel
static {
try {
UIManager.setLookAndFeel(new MyNewLookAndFeel());
catch (Exception e) {}
I do not get any exceptions and like I said, everything works great when loaded with appletviewer.
I have tried adding the SwingUtilities.updateComponentTreeUI(this); in either the start(), init(), or my own createGUI() function and it still does not work.
Any ideas? Could this be a problem with the browser caching the applet? I am using IE 5.50.

I have the same problem
putting them in static doesn't keep the look and feel
putting them in the applet constructor does'nt keep it
putting them in init() doesn't keep it
putting them in start() doesn't keep it
heck, even putting them in all 4 of them together doesn't keep the look and feel, it always reverts back to metal

Applet not opening a socket on its own host. Please help.

I have also posted this in JSC2 forum.
My applet is not able to open a socket on its own host.
The applet is being served by a JSP (developed using Sun Creator2) from my laptop behind a DHCP broadband router at (say) 125.238.104.132 at my residence. I have a URL �samsub.no-ip.biz� that redirects port 80 calls to 29080 where my application runs. All required router rules/mapping are done and the JSPs run perfectly fine. In one of the pages, I have inserted an applet inside an escape disabled statictext field as follows:
<applet code="AppClient.class" width=540 height=440></applet>
The applet code and the test server code are shown below for your analysis. Note that, when run on the same machine (at home), the applet works fine. The commented lines will show other failed test. The error reported at the java console was: null pointer at line 56
Could someone help me please. Thanx. MarySam

Hi Guys,
I'm not actually from Mozilla Firefox, but I've had this problem before, and I've solved it with the help from another website.
What you need to do is download a programme called "tdsskiller" from here:
http://www.geekpolice.net/t23369-computer-infected
scroll down the page and you should see a link. (I know the article itself seems irrelevant to your problem, but trust me, the programme they recommend works on this virus too.) It's only 1.3MB or so, so it doesn't take up huge amounts of space either! :)
I can safely say that it is COMPLETELY safe to download this from geekpolice.net, as this website is a free website which helps people with viruses on their computer. If you ever have another problem with anything to do with computers, go and have a look on geekpolice.net, they should have something that might help you.
Before anyone wonders why I am singing its praises so much, no I am not advertising them for any personal gain, but they have helped me get rid of some pretty nasty viruses on my computer before, so I am very grateful to them :)
SO, anyway, after you've downloaded the tdsskiller, you should run it, and it may find some infected files, in which case let it repair them. After rebooting your computer, the annoying opening tab thing should be gone!
I hope this works for anyone who's stuck :) If it doesn't, I'm really sorry, but it has definately worked for me!
Good luck!
Yashmeee :)

Applet runnning jre7 sends tons of PersistenceDelegate requrests to server:

Our server runs jdk1.6. Applet runs on IE7. Just recently, some clients with jre1.7 experiences slow down. By monitoring our Apache Mod_jk log, we see tons of requests from client such as:
GET /epen-webapp/java/lang/ClassPersistenceDelegate.class
GET /epen-webapp/java/util/PropertiesPersistenceDelegate.class
GET/epen-webapp/java/util/HashtablePersistenceDelegate.class
GET/epen-webapp/java/lang/IntegerPersistenceDelegate.class
This is likely because of some changes in java 1.7 on XmlEncoder change. As we use XmlEncoder in transporting data between client and server. Somehow, the XmlEncoder in 1.7 does not know how to persists Integer, Propertyies and Hashtable?
We don't recognize these classes and don't know why these are being requested by the applet.
Applets running jre1.6 do not have this problem.
Our server is jboss 4.3 eap running on jdk1.6.
Here is how the applet is embedded:
document.write('<object classid="clsid:xxxxxx" width="100%" height="100%" align="baseline">');

My organization is experiencing very similar problems. We have resolved it through several steps.
We upgraded the client to Java 8 and we saw in the console that the hanging connection with the Domain Controller no longer occurs. This may be all that is necessary for your environment as well.

Changing LookAndFeel for JSP

Can some1 help me in changing the LookAndFeel of a JSP page?? What i want to do is create JButtons, JTextfields etc..... with a new LookAndFeel..just like we do for a swing JFrame...how can I do this for a jsp page ??

I want hardware access on the server and not the client browserWell that makes things easier for you, you wont need to bother with an applet, you can use jsp.
I have coded for accessing the hardware ports on server by using JavaOk so you have classes written already.
You can access these classes / methods from your jsp page, however you will have to take out all the GUI stuff, so it is just the code for accessing the ports left in the classes.
You then create your user interface using html etc. in a jsp page.
Within your jsp you can call the methods of your java classes to embed information into the html.
If you read up on accessing java beans, this will show you how to access your classes (even though your classes are not beans).

Macintosh support for Java applets

Is there a way to auto-install the Java Runtime and plugin for Mac browsers like Internet Explorer and Netscape?
Do the <object classid...> tags work on Macs too?
I do know that Mac OS X shipped with Java 1.3.1. But how can I find out if the plugin is supported by a Mac user's browser?
thank you very much.

LookAndFeel=oracle in Formsconfig

Dear All
can any one tell me if i changed lookAndFeel=oracle to Generic then what will happened ?
And also tell me what else i can give here ?
And also tell me i have to changed here only or in the below also .. What is the difference ?

lookAndFeel and colorScheme control the way the applet appears. LookAndFeel is used to control...well...the Look and Feel. To compare: this is like in Swing where you have MetalLookAndFeel, Motif, (you have different look and feels in forms)...ColorScheme controls the default colors of the forms components (e.g. color of Tab Pages etc.)
For legal values for lookAndFeel and colorScheme take a look here:
http://download.oracle.com/docs/cd/B14099_19/web.1012/b14032/configure003.htm#sthref178
if you set the look and feel to generic then colorScheme is ignored (just as indicated in the documentation :p ) so there would be no point in changing the look and feel to generic and changing the color scheme too.
cheers

Lookandfeel 10g

Hi.
I'm developing a Forms/Report 10g application.
It is a migration from a previous 6i application.
That application (the same code) runs under 2 different Application Servers.
One has Linux, the other one Windows.
In both apps servers, the configuration of lookandfeel is setted "generic",
but the canvas in the applet are significantly different.
Under linux, it has the same look of the 6i client/server version.
Under windows, some fonts, background color, etc. are changed; Strings are of the same color of the background, making them not readable. Fonts are not clear.
Why this could be? There's a sort of configuration for default fonts and color in the Application server?
Thanks!
Sebastian

see your <DEVSUITE_HOME>\forms\java\oracle\forms\registry\Registry.dat file

Blank applet using Sun JRE plug-in on 10g

I have successfully run multiple forms using WebUtil with JInitiator on 10g DS and
AS. I have been struggling with getting forms to show up in the applet when I try to
use webutiljpi.htm. When I try to run a form from the builder, It loads an applet with
a broken image icon in the upper left hand corner and the status bar reads:
Loading Java Applet Failed...The java console gives me this(removed header stuff):
Java Plug-in 1.5.0_12
Using JRE version 1.5.0_12 Java HotSpot(TM) Client VM
User home directory = C:\Documents and Settings\xxxxxx
load: class oracle.forms.webutil.common.RegisterWebUtil not found.
java.lang.ClassNotFoundException: oracle.forms.webutil.common.RegisterWebUtil
I looked in Metalink and found an article talking about the webutil.cfg file and
assuring that the path to frmwebutil.jar isn't identified properly, but I think it is.
Anyway, I'm stuck and I must be missing something easy. Here are the entries for
my JInitiator and JPI configs and my default.env file. Any help would be greatly
appreciated.

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();
     }

Open web pages from an applet

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.
Andrew.

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,
Jim

Check 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. ;-)
