Putting JLabel icon images in .jar

I'm trying to make my program display JLabels with icons. This works successfully, however it relies on local files. I want to distribute the jar file only, so I was hoping there was a way I could put the images in the package or subfolder within the jar file and have the code reference the pictures there. Is there a way to do this. The code I'm using now is as follows :
if(status.equals("good")){
return (new JLabel(new ImageIcon("images/OK.gif")));
}else //if(status.equals("bad"))
return (new JLabel(new ImageIcon("images/FAIL.gif")));
Thanks for any advice you my have.

Putting both the class files and the images files in the same jar definitely works.
I do it all the time. The simplest thing to do is to put the images in the same folder
as the class file that accesses them, then jar up the lot. Your code should look like:
URL url = this.getClass().getResource("your_image.jpeg");
Icon icon = new ImageIcon(url);
//etc...In fact, you should always code in this way: this code works will a jarred or unjarred program.
Because with file names, however: jar file names are always case sensitive.

JLabel (icon Image) without picture?

I am make applet containing JLabel (Icon Image). When I run this applet from server and used image-file "middle.gif" (from tutorial) - there was all Ok. After this I changed color of image on MS Photo Editor and now I get JLabel without icon and there is no errors. I don't understand what happens? Anybody know what is it?

Of course. In directory "Images" I have follow files:
green.gif
middle.gif
red.gif
Files green.gif and red.gif are middle.gif but pictures on them have respective colors. This colors I get using MS Photo Editor.
import javax.swing.*;
import java.awt.*;
import java.net.*;
public class tLabImage extends JApplet{
public void init () {
JFrame f=new JFrame();
URL url=null;
try {
// url=new URL("http://10.1.1.6/Images/middle-1.gif");
url=new URL("http://10.1.1.6/Images/green.gif");
catch (MalformedURLException e) {System.out.println (e.getMessage());}
Image image=getImage(url);
ImageIcon icon=new ImageIcon(image);
JLabel l=new JLabel ("text", icon, JLabel.LEFT);
f.setLocation(200,300);
f.getContentPane().setLayout(new GridLayout(0,2));
f.getContentPane().add(l);
f.pack();
f.setVisible(true);
When I run this programm I get JLabel without icon (only text). Why? Who can answer?

Cannot show icon images

I just try to upgrade my 6i application to 10g web base. I sucess to run my application on browser. However, I cannot show icons image. I have followed the doc "Forms9iAS Forms Services How to deploy Icons", but still failed.
Is there any doc teach me how to deploy icons in Forms Services 10g? (not 9i)
or any hints can tell me?
Thanks a lot !!!

Hello,
1) if you choose to have icons as gif, use the following in a batch file:
rem====
jar cvfm iconeweb.jar *.gif --- name the file: jar_icons.bat
rem=====
put the icons images in a directory together with jar_icons.bat
2) run jar_icons.bat
you should see a new file in the directory: iconeweb.jar
copy that jar file in the directory /forms/java of your developer install directory.
3) open the formsweb.cfg which you can find in /forms/server in the directory where you installed developer 10g
Look for the line that has: archive_jini
Add the following: at the end of this line: ,iconeweb.jar
save formsweb.cfg
if you are running your app from a named config, you should also make the change to that section too.
4) restart your browser that the new jar is downloaded.
5) open your java console: it is the small coffee icon you see in the systray. In it, you see a line with iconeweb, If you don't see it, it means the jar file is not found. Then, you should make sure that the forms/java path is indeed in the forms_path registry key .

How Do I get icons image directory to work in a JAR file?

Yes, I must admit after going through the tutorial and other stuff I am stiil stumped
I have an application that uses the jlfgr icons for the toolbar, and it works fine as long as i actually run it from the directory that it is in.
I would like to put in into a jAr file, and be able to execute it from other places.
I have a Directory named PhoneBook
in that are the classes I use
AddressBook - the main class
PersonEntry - The 'data class'
and various other things like FileFilters.....
inside that directory there are two more:
images - contains all the icon images
Data - where the default 'database' entries are stored.
I use code like this:
     private void fillToolBar( JToolBar bar )
          Dummy = new JButton(new ImageIcon("images/New16.gif"));
          Dummy.setActionCommand("New");
          Dummy.addActionListener(this);
          Dummy.setToolTipText("New");
          bar.add( Dummy );
          // etc etc
to get all the icons into the toolbar
I have made a Jar file that has all the classes and all the directorys with the icons in it
and so the program runs, but does not get the icons for the toolbar, I just get a whole load of 'dud' buttons.....
AS this is the first time i've ever got the GUI to look right rather than just the code functioning properly
I'd like to get the whole thing in a working Jar file
So Could someone show me Step By Step, How I get my classes and images into a Jar file
so that i can from a different directory go
java - jar Phone.jar
and have the GUI come up with all the images, assuming I'm totally thickheaded when it comes to Jar files.?
I also can't get the images to show up if I merely run the 'program' from another directory than the one it is compiled in
I can get the program to run, just not access the images with something like
java -cp blah/blah/blah AddressBook
{the main class is AddressBook }
the data directory can be anywhere as I use a JFileChooser to allow the user to open and save desired files.
I really would appreciate some clear workable help. {though I'm running out of Duke Dollars...}

What you need is a correct path to the directory
inside of the jar. This can be accomplished by adding
a line to your main program like this:
URL
url=myProgram.class.getResource("images/New16.gif");
Dummy = new JButton(new ImageIcon(URL));
where myProgram.class is the name of the class
file that contain the main method.
Hope this helps....
;o)
PS: I don't want your dukes...I got them coming out of
my ears!
O.K, that works thank you.
I put something like:
for all the 'buttons' in the toolbar
URL url = null;
Class ThisClass = this.getClass();
url=ThisClass.getResource("images/New16.gif");
Dummy = new JButton(new ImageIcon(url));
Dummy.setActionCommand("New");
Dummy.addActionListener(this);
Dummy.setToolTipText("New Database");
bar.add( Dummy );
etc for all the rest of the 'buttons'
After Reading the API docs on URL's etc I'm still not sure as to why it works, but it does....
I am able now to place the class files in a jar along with the images and it all works fine
although now I don't quite follow all my code....................
I assume that
url=ThisClass.getResource("images/New16.gif");
returns some sort of 'relative url ' ???
Thanks for the help though.

Loading all images from Jar include the directory structure.

Hi I would like to puts all my images in a Jar. is it going to improve the loading speed?
I have a ImageLibary that load all the images to a hashtable and access each image by their path and filename.
I only have to input the image root directory and it will load all the images including sub-directory. If I decide to put these directories in a JAR. is this still going to work? Do all the class files has to be in the same JAR?
use getResourse()?
My current ImageLibary is like this:
public class ImagesLibary extends Component
private Hashtable imagesBank;
private Vector imagesName;
private MediaTracker tracker;
public ImagesLibary()
imagesBank = new Hashtable();
imagesName = new Vector();
tracker= new MediaTracker(this);
loadImageFile("./images");
for(int i=0; i<imagesName.size(); i++)
String key = (String)imagesName.get(i);
Image image = getToolkit().getImage(key);
tracker.addImage(image, 0);
try
tracker.waitForID(0);
catch (InterruptedException e)
System.err.println("Loading image: " + key + " fails. " + e);
imagesBank.put(key,image);
System.out.println("Loaded: " + key);
System.out.println("Total of " + imagesBank.size() + " images.");
private void loadImageFile(String dir)
File imageDir = new File(dir);
File temp[] = imageDir.listFiles();
for(int i=0; i<temp.length;i++)
if (temp.isDirectory())
loadImageFile(temp[i].getPath());
else
imagesName.add(temp[i].getPath());

is it going to improve the loading speed?depends :)
is this still going to work?some ajustments are needed... but thats done quickly.
Do all the class files has to be in the same JAR?no. but it's easier to handle.
use getResourse()?yes. don't know if u have to. but i do it this way :)
inside an application:
URL keyboardImagePath;
keyboardImagePath = (new Object()).getClass().getResource("/gfx/keyboard.gif");
Image kb=getToolkit().getImage(keyboardImagePath);inside an applet:
URL path = (new Object()).getClass().getResource( "/icons/right.gif" );
// now make the icon getting the gif from the url
ImageIcon = new ImageIcon( path );inside a hybrid:
URL keyboardImagePath;
keyboardImagePath = (new Object()).getClass().getResource("/gfx/keyboard.gif");
System.out.println("<-(application)load:"+keyboardImagePath); //if u wanna c what happens
if(keyboardImagePath==null)
keyboardImagePath=selfRef.getClass().getResource("/gfx/keyboard.gif");
System.out.println("<-(applet)load:"+keyboardImagePath); //if u wanna c what happens
Image kb=getToolkit().getImage(keyboardImagePath);hope that was helpfull :)

Icon/Image display

Hello!
This is my code, and my problem is that I put 2 images to the same place, the second picture is smaller than the first but if I put the second I can't see the first... How can I solve this problem? I want to see each image in same time. Can this be solved with swing? And if yes, can you guys show a little code of how? And sorry for my bad english...

        return new JScrollPane(label);

You are trying to set the content pane to two different things when it can only have one. If you want the images overlapping, draw one on top of the other:
    public static void main(String[] args) throws IOException {
        String path1 = "100.png";
        String path2 = "1016.png";
        URL url1 = kep.class.getResource(path1);
        URL url2 = kep.class.getResource(path2);
        BufferedImage image1 = ImageIO.read(url1);
        BufferedImage image2 = ImageIO.read(url2);
        Graphics imageG = image1.getGraphics();
        imageG.drawImage(image2, 0, 0, this);
        imageG.dispose();
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(new kep().getContent(image1));
        //f.setContentPane(new kep().getContent(image2));
        f.setSize(400,400);
        f.setLocation(200,200);
        f.setVisible(true);
    }

Reading Images from JAR Files

Hi,
I am having a very difficult time being able to read images from a JAR file via my Applet. I have tried everything that I know about with no luck. The only way I can get this to work is to store the images individually in a sub directory of public_html on the websever. This works, but I would like the images to come down in a JAR file for performance reasons.
I am using Internet Explorer 5.5 for my browser. I checked the options and everything seems to be in order, but......
I would appreciate any feedback that anyone might have on this topic..........
Thank You....

once in a jar file i inserted a image
the jar file on clicking starts an frame.
so the image was for getting that image at the icon place at top and at minimized window
i could not get that image from jar file by new imageicon().getimage();
but i get the image if it is in the directory in which jar file is.....
can one explain the reason

Problem loading image from jar file referenced by jar file

First, I searched this one and no, I didn't find an answer. Loading images from jar files has been pretty much done to death but my problem is different. Please read on.
I have my application, a straight up executable running from Eclipse. It uses a jar file, call it JarA. JarA launches a GUI that is located in another jar file. Call it JarB. To recap:
My application calls JarA -> JarA loads classes from JarB -> JarB looks for images to place in a GUI it wants to show on the screen
When JarB goes to load an image the following happens:
java.lang.NullPointerException
     at sun.misc.URLClassPath$3.run(URLClassPath.java:316)
     at java.security.AccessController.doPrivileged(Native Method)
     at sun.misc.URLClassPath.getLoader(URLClassPath.java:313)
     at sun.misc.URLClassPath.getLoader(URLClassPath.java:290)
     at sun.misc.URLClassPath.findResource(URLClassPath.java:141)
     at java.net.URLClassLoader$2.run(URLClassLoader.java:362)
     at java.security.AccessController.doPrivileged(Native Method)
     at java.net.URLClassLoader.findResource(URLClassLoader.java:359)
     at java.lang.ClassLoader.getResource(ClassLoader.java:977)
     at org.cubrc.gmshell.gui.MainWin.preInit(MainWin.java:152)
     at org.cubrc.gmshell.gui.MainWin.<init>(MainWin.java:135)
The code from JarB that loads the image looks like this:
          URL[] oSearch = {Main.class.getResource("images/")};
          URLClassLoader oLoader = new URLClassLoader(oSearch);
          imgIcon = new ImageIcon(oLoader.getResource("icon.gif"));
          imgMatchRunning = new ImageIcon(oLoader.getResource("gears.gif"));
          imgMatchStill = new ImageIcon(oLoader.getResource("gears-still.gif"));
          imgMagnify = new ImageIcon(oLoader.getResource("magnify.gif"));This looks right to me and JarB certainly has an images directory with those files. But I'm in hell right now because I don't know where to place the images to make this work or if you can even attempt to load images with a dependency chain like this.
Any help very appreciated!

Have you tried to move your image-files out of the jar file and place them in the sam folder as the jar-file? I think that would help.
When you try to load the image-file you get the NullPointerException because the program tries to read a file it can't find. Remember that a jar file IS a file and not a directory.
If you want to read somthing inside the jar-file you need to encode it first.
Have you tried to read the jar-file with winRar. It makes it easy to add and remove files in your jar-file.

How can i acces the images from jar to with in jar

I want to now make a executable jar file which contain all class files and one jar file (which contain all images).
before jar i use
icon=new ImageIcon(getClass().getResource("image.gif"));
now what can i do and it is possible that no change in the path of image icon.

A jar inside a jar wouldn't be a good idea I don't think- you'd end up having to code around some things to get at the internal jar instead of being able to use code like "getResource()" like you posted.
Consider an ANT task that will handle building your jar for you, if this is a logistics issue. The task can unzip the image jar and shove it in with the application jar.

Can I seperate the icon images

In the JNLP file you can specify 3 icon images for 3 different sizes, 64 * 64, 32 * 32 and 16 * 16 pixels.
<icon href="iconStartMenuSize.jpeg" width=16 height=16/>
<icon href="iconDesktopSize.jpeg" width=32 height=32/>
<icon href="iconSplashScreenSize.jpeg" width=64 height=64/>
I know that if you just specify 1, Web Start automatically resizes it to make the other 2. I've heard that in earlier versions of Webstart it only ever uses the first icon you give it, even if you give it 3. Does anyone know if, in version 1.4.2, it will actually use the 3 different images if you supply them?
If nobody knows I'll test it and post the result. This was posted before, I am running into the same problem right now.

can somebody give an answer to this question? I want to put the correct size icon on the desktop, download splash and shortcut.
Thank you

Iconic images on multirow buttons

Hi,
I am trying to get different iconic images displayed on a button in a multirow block. Is there any easy way to do it. Running Forms 10g
example
I have a block based on customer orders which displays 10 rows
I want to display an iconic image on a button in the multirow that shows a different image depending on the status of the order e.g. ordered, dispatched, cancelled etc etc
so row 1 would show image1, row2 image 2, row3 image 1 and so on, each row could be a different image or the same image
As I scroll up and down records refreshing the data displayed in the multi row I would want the images to change as well
Tried set_item_property (icon_filename) but this sets all instances of the button to the same image, set_item_instance_property cannot set the Icon Filename.
Can this be done in javabean?, can you reference the individual row instance's of the javabean.
Any possible solutions?
Thanks

I have also tried to "simulate" this using an image-item, but the image doesn't populate. I put the code for read_image_file in post-query trigger thinking this would be most appropriate.
Even when I put it in a When-New-Record-Instance as I scroll up and down the records in the block the images clear and don't refresh as expected

How to make an icon image using Photoshop

I found out how to do this recently so I decided that I wanted to make a tut for those who don't know how to make an icon image. This icon image is for the libraries tab on your computer. Under the libararies tab there is Music, Pictures, Documents, and Photos
First you will need the ICO (Icon image format) Format extension for photoshop which can be downloaded here:
http://www.telegraphics.com.au/svn/icoformat/trunk/dist/README.html
The download link and tutorial on how to install it is all in the link above.
Once you have that all set you can now launch photoshop to create your icon image. Once you have launched it, create a new document with the size as in the image below.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/256x256_zpsbf3dcf8e.png~original[/IMG]
Create the image you want. I used a simple one by using the custom shape tool by pressing "U" on your keyboard and with the
basic blending options.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/IconImage_zpsd788c709.png~original[/IMG]
The reason why the image is pixelated is because it is an icon image. Since the image is only 256x256 pixels when you zoom in on it that will get you the pixely result. The reason why I zoomed in is so you can see it. But don't worry this is no the end result. Just continue reading and you will see.
So once you have created the icon go ahead and press
file>save as>(under format choose the ICO)>and choose the name that you want to name it. And save it in your C: drive. You will see why to save it in your C: drive in a sec.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/SampleicoPic_zpsd252bfba.png~original[/IMG]
So now that you have created the icon and saved it now you can create the new library.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/NewLibrary_zps8ca703b2.png~original[/IMG]
Name the library whatever you want I named it "Sample" for tutorial purposes. Notice how it gives you a default boring icon image for your library.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Sample1_zpsb5472840.png~original[/IMG]
So now once you have created and named your library now it is time to get the icon image into place.
Go to computer/c: Drive/users/YOU/ And now once you have reached this area you will need to access a hidden folder named "appdata" to do so press "Alt" then a menu bar will show. Click
tools>folder options>and view. Find the option to view hidden folders then press apply then ok. Now we shall continue so AppData>Roaming>Microsoft>Windows>Libraries
Now you should see all the libraries including the one you just created.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/showhiddenfolder_zpsad4a3c94.png~orig inal[/IMG]
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Libraries_zpsf6243bc0.png~original[/IMG]
Once you have reached your destination then open a new text document with notepad and drag the library you just created in notepad. The result should look like this:
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Notepad_zps251a86f0.png~original[/IMG]
once you have reached this point click at the end of the second to last line down then press enter and enter in this information
<iconReference>c:\"NAME OF ICO FILE YOU CREATED IN PS".ico</iconReference>
Example:
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/iconreference_zps1c1a3eca.png~origina l[/IMG]
Once you have entered that information go to file>save and the icon image should appear on the library you created.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Finished_zps267f893a.png~original[/IMG]
Now you are officially finished. Go and spread the news and joy. Bye for now

It is Windows only because all those screen shots are exclusively Windows, the file structure and paths do not resemble those of the Mac in the least. As a Mac user, there's nothing I could take from your tutorial. Sorry,
No drives named with letters like C: on the Mac, for instance. No backward slashes either, ever. No such paths either. No "Notepad" on the Mac, we use TextEdit; but such a text editor is not remotely needed on the Mac to make and/or edit icons. Etc.
Those folders are not even called "Libraries" on the Mac… Nothing resembling your tutorial at all.

I have an IMAC I bought from a friend. I think he wiped it clean. I tried to go to panasonic to download a driver for my camcorder. It put an icon on my desktop that is setup-1.exe when I try to open it, it says I don't have a program to open it with.

I tried to download a driver from Panasonic for my camcorder. It puts an Icon on my desktop that is called set-up1.exe. when I try to open this I get an error message that says I don't have a program to open it. any suggestions. Also, I tried to download the latest ITunes. It put an Icon on my desktop but won't let me open it or run it.

In general, you don't need drivers for camcorders on Macs, and the .exe file you downloaded is a Windows program, which won't run on a Mac unless you also have Windows installed.
It would help a lot if you tell us the exact model camcorder you are using, and what application you want to use it with.
Regarding iTunes, the latest version is iTunes 11. You need to have OS X 10.6.8 or later to install iTunes 11. Your profile says you have OS X 10.4.11, which is a much older version of OS X, so you won't be able to install iTunes 11. (Here are the iTunes 11 specs.)
