Re: jar files and gifs

["Antonio W. Lagnada" <nf...@msn.com>]

Is this a java/java swing app or a servlet/jsp?  I am confused since this is a tomcat user mail group.

Anyways, if it is a java app, one example would be (if you are using ImageIcon or other classes that supports URL in their constructor):

URL imageURL = System.getClass().getClassLoader().getResource("MyImage.gif");  
ImageIcon imageIcon = new ImageIcon(imageURL);

If this is a JSP/Servlet question, one approach is to create some image factory that reads the image.  This image factory will then convert the image into byte streams so the web browser would be able to display it.

** Note that the above example assumes that it is located on the root of the jar file, not in a folder hierarchy somewhere.
You may need to use getResource("images/Myimage.gif").  I don't know if this works.

If you have a servlet that returns a bytestream give the gif file name, ie
http://localhost:8080/ImageService?imageName=MyImage.gif

You would be able to utilize this in html/jsp as:

<image src="http://localhost:8080/ImageService?imageName=MyImage.gif">

You will also have to load the image via the URL.openConnection(), etc...

Hello,

    I have a jar file, which contains some java .class files and two directories /images and /sounds. The problem is when I run the jar file, the images from it are not found. So, on the screen I don't see any gif.  
    Could anyone tell me how could I access the gifs files from the jar archive ?

Many thanks,

Hi,

    Sorry for confusing you, I was talking about an java application, not a
jsp.
 Anyway thank you very much

Sincerely,
Adrian
