Hello Radha
First: The getSystemResource of the class ClassLoader don�t returns a ImageIcon, it returns a URL !!
When you put all classes into a jar file, you must to use all pictures into jar too !!!

Hi
Thanks for the reply.
Yeah i am using thst URL to construct object of ImageIcon like below.
new ImageIcon(imgURL, description).
Could you please let me know how to put imgae in jar file
my imgae is in a directory c:/images/logo_jpmf.gif.
while creating jar file if i say
jar -cf cfunds.jar /com/chase/impb/tokyo/matrix2/cfunds/*.class ,/images/logo_jpmf.gif
its giving error.
Can you please tell me how to create a jar file by includingh the image.
After that do i need to copy the image where ever i put this jar or would it take from jar file only???

Hi
I am able to include the image in jar file but still its not able to locate the file.

ImageIcon createImageIcon(String path, String description)
{
System.out.println("-------path:"+path);
try
{
URL imgURL = ClassLoader.getSystemResource(path);
System.out.println("-------imgURL:"+imgURL);
if (imgURL != null) {
return new ImageIcon(imgURL, description);
} else {
System.err.println("Couldn't find file: " + path);
return null;
}
}catch(Exception e)
{
e.printStackTrace();

The path into your jar is equals to the path into code
Ex.: "images/logo_jpmf.gif"
into jar
archive.jar
images
|
---logo_jpmf.gif
