Image in a bottle ... I mean jar

I am trying to create an app and package it into a jar file. I however have a gif that I want to be an Icon for my program I want to include it in the jar file. When I do this it doesn't work. it seems as thought the image isn't there. I am currently treating it as though it is in the present working directory in the program ie "image.gif" when I create the image in my main class.

How are you creating the Image or Icon that's not working and where is the image file within your JAR?
Usually all that's required is new ImageIcon("images/shirty-man.gif") where the image is in the "images" directory of your JAR. If it's buried in a sub-package somewhere then you'll need to pass that in as well.
Hope this helps.

How to add multiple images to a JLabel from the jar file

I want to add multiple images in a JLabel but the icon property only allows me to add one. I thought I could use html rendering to add the images I need by using the <img> tab, but I need to use a URL that points to the image.
How do I point to an image inside the jar file? If I can't, is there another way to show multiple images in a JLabel from the jar file?

Thanks, it works perfectly. It's a really smart way of fixing the problem too :)
I also found your toggle button icon classes which is something I've also had a problem with.
Thanks.

How to pack the images i use in swing into jars

I know how to pack my programs into jars, but how can i also pack in my images used by my program, they dont work when outside the jar.. Thanks

i am not if my answer satisfies your requirement.
Even we also used images in my swing application and made it executable jar.
what we have done is we have done is as below
icon = new ImageIcon(new URL("http://xyz.com/ui/v8/images/icon-information-blue.gif"));
so in this case ,no need of images to be packed along with jar ,you can access the images which is there on net..
thanks.

Were you using third-party software when the panic occurred? Is the panic repetitive or it just happened once? IN the latter case it could simply be a software glitch. But if it's repetitive then there's some other problem either hardware or software. Use the Console application in the Utilities folder and review the console log around the time of the panic to see if there are additional clues to the cause of the panic.
The error indicates that the problem was a failure to respond to an interrupt by the CPU. Now this could simply be caused by a software glitch, but it could be a hardware problem related to the CPU. In the latter case the panic would probably become repetitive, in which case you would want to take the computer in for service to be sure the CPU isn't failing.

Links to images not working when saving to JAR

Hi
Okay Ive created a Java GUI app with Eclipse and it all works fine until I try to save it to JAR.
Basically the images don't load.
grassIcon = new ImageIcon("images/grass.jpg");
antIcon = new ImageIcon("images/ant.jpg");
lionIcon = new ImageIcon("images/lion.jpg");
is what I am using so the images are in a folder named "images".
I've checked the JAR file and it does contain the folder with the images and it looks like everything else is running.
Cheers for any help with this.

Image not displayed while running executable jar ?????

hello everyone...i have developed a game like mario and everything is happening well......
i have created an executable jar file of my game so that i can distribute it to my friends.............
now the problem is :
my all the images that are used in my game are in "Images folder", so when i run my executable jar file outside the reach of images folder than images does not get displayed on my game.................i mean when jar file is located beside my images folder then images get displayed but if i move my jar file to some other location then images doesn't get displayed.......
i have included images folder inside my executable jar file.....but same problem arises......
in my game, to display images i have used this code:
Image img=new ImageIcon("Images\\hero.gif").getImage();
so Images folder should be located at the same directory where my game is located....................
so can anyone tell me why this is happening ?
i want to execute jar file even if i relocate my jar file(i've put images folder inside jar).......

inside my jar , i have these three folders:
engine play res manifest.txt
engine and play are packages
to load an image i have used these code
Image img=new ImageIcon("res\\t.gif").getImage();
to draw image:
g2d.drawImage(img,x,y,this);
i had also used what u said :
img=ImageIO.read(Thread.currentThread().getContextClassLoader().getResourceAsStream(path));
Note: earlier u adviced me ImageIO.read(Thread.getContextClassLoader().getResourceAsStream("res/y.gif"));
getContextClassLoader() is not an static method so i can't acess it from static context.It gave me compilation error.so i used Thread.currentThread().getContextClassLoader().
and i haven't used BufferedImage.I have used Just Image.

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 an image into an Applet from a JAR file

Hello everyone, hopefully a simple question for someone to help me with!
Im trying to load some images into an applet, currently it uses the JApplet.getImage(url) method just before registering with a media tracker, which works but for the sake of efficiency I would prefer the images all to be contained in the jar file as oppossed to being loaded individually from the server.
Say I have a class in a package eg, 'com.mydomain.myapplet.class.bin' and an images contained in the file structure 'com.mydomain.myapplet.images.img.gif' how do I load it (and waiting for it to be loaded before preceeding?
I've seen lots of info of the web for this but much of it is very old (pre 2000) and im sure things have changed a little since then.
Thanks for any help!

Hi
Error -50 paramErr Error in user parameter list
Can there be any external hard disks - if so How is/are it/they formatted ? Must be Mac OS Extended (hfs) if used for Video.
UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.
What this means in Your situation is above me.
• free space on internal boot hard disk? How much ?
Video codec
• streamingDV, AIC etc. (not .avi, .mp4, .m4v, .wmv etc as they are containers not codecs)
Pictures
• in what format ? .jpg, .bmp, .tif, else ?
Audio
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
The "com.apple.iMovie.plist" file
Many users has not observed that there are TWO libraries.
• Library - at root level
• Library - in user/account folder - THIS IS THE ONE to look into
from Luke Burns
I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.
I don't know why that could cause that big of a problem, but it did..

You need more free space on your hard drive.

Where do Your material come from
• Camera
• External hard disk
• USB-memory
And all are connected so that iMovie can find it ?

I reset my ipod touch, and a picture of a usb cable and itunes image appeared, what does that mean?

please help me, i dont know whats wrong

This means your iPod is in recovery mode, try restarting the device agian (Hold the home + Power button for 10secounds), if the device goes back to this screen you will need to plugg it into your computer and most likely have to put all your content back on the device and restore from a backup

Images are not comming out when application is running through jar file.

Now, I created a jar file for my application in the following steps.................................
          STEP-1:          Firstly, I created a text file(mainclassInfo.txt) that contains
          the line:--     Main-Class: Examination
          This line would be automatically added to the default manifest file when I would include the                name of that text file with the command to create the jar file.
          Location of the text file I created:     C:\mainClassInfo.txt
          STEP-2:          Then I went to C:\Examination and executed the following command(by using                'Command prompt'):--------------------------------------------------------------------
jar cmf C:\mainClassInfo.txt Examination.jar Examination.class ExamBox.class PaperSetterBox.class pspBox.class epBox.class TimerBox.class ReportCardBox.class HelpBox.class AboutBox.class Images Sounds
Finally, I got the jar file:-     Examination.jar
Double clicking on it application ran as it was expected.
Then, I thought, that as all the files & folders the application needed to run properly were packaged in the jar file; I should delete all the contents of the folder 'Examination', so that no one could see or use anything of the resources easily. I did that.
So, then it became only:-- C:\Examination\Examination.jar
Thereafter, I tried to run the application again and there a problem occurred! The application was running, but the images, those were to be used and shown by the application were missing somehow!!
Moreover, when I kept a copy of those 2 folders('Images' and 'Sounds') into the C:\Examination and ran the application again all the images came out normally!
I just can't understand why it's happening so mysterious?
I don't want to leave anything of the resources in an open place; I mean, outside of the jar file. The images should be used and shown by the application.
Help me please!

The Image class itself does not have any methods for loading images from files so you must be using something more. Most methods for loading images from files have an overload that lets you use a URL, so you just need to use that method with a call to getResource like in the other thread. If you can't think of anything else, you can use ImageIcon to load an Image (the Image is returned by a call to ImageIcon.getImage). See also "how to use icons" from the swing tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/misc/icon.html

How to delete a jar file after loading image files from it

Hi,
How can I delete a jar file after some image files have been loaded? For example, say, I have "a.jar" which contains an image "a.gif" in the root directory of the c drive. I would like to get the image size and then delete the jar file. Here is the code snippet:
    URL url = new URL("jar:file:/C:\\a.jar!/a.gif");
    Icon icon = new ImageIcon(url);
    System.out.println("icon size ? " + icon.getIconHeight());
    File file = new File("c:\\a.jar");
    while(file.exists())
        file.delete();
        try
            Thread.sleep(100);
        catch (InterruptedException ignored)
    System.out.println("file deleted.");I get the image size correctly but just can not delete the jar file. Apparently the file handle is not released, but how to close it? Any hint will be appreciated.

I am sure the URLConnection.defaultUseCaches is set before it is connected otherwise I should catch an IllegalStateException on conn.setUseCaches(false).
        try
            URL url = new URL("jar:file:/C:\\a.jar!/a.gif");
         URLConnection conn = url.openConnection();
         conn.setDefaultUseCaches(false);
         conn.setUseCaches(false);
            Icon icon = new ImageIcon(url);
            System.out.println("icon size ? " + icon.getIconHeight());
            url.openConnection().getInputStream().close();
            System.gc();
         System.runFinalization();
            File file = new File("c:\\a.jar");
            while (file.exists())
                file.delete();
                try
                    Thread.sleep(10);
                catch (InterruptedException ignored)

Images not appearing in jar file

Hi, i've created an executable jar file for my project in order to send it out for user evaluaution. The problem is, none of the images contained in my project resources package show up when the jar is run (e.g. the start up screen image, GIF/JPG/PNG icons for the fileview of the filechoosers etc..).
I'm basically doing something along the lines of.....
File imgFile = new File(path); //where path is something like "resources/startup.PNG"
imageIcon = new ImageIcon(imgFile.toURL());
to access the images.
I've checked the jar file and the images are definitely in there. Anyone know why they aren't showing up?

Because your code says that they're files in their own right. You need to either use a jar:// URL or use Class.getResource / Class.getResourceAsStream.

Images in a JAR file

Hi all,
I need see by code all the names of the resources (Images) that are includes into a JAR file. There are some function that do that work?.
Thanks in advance!!
Salvador Huertas.

For example          /* test.jar is a jar file containing some files, one directory named traffic
             and some files in the traffic directory. */
          JarFile jf = new JarFile("test.jar");
          Enumeration enum = jf.entries();
          ArrayList list = new ArrayList();
          while(enum.hasMoreElements()) {
               String s = enum.nextElement().toString();
               if(s.indexOf("traffic/") > -1 && s.length() > "traffic/".length()) list.add(s);
          System.out.println(list); //Displays the files in the traffic directory
