When running a Java app from eclipse my ImageIcon shows up just fine.
But after creating a jar the path to the image obviously gets screwed up.
Is there a way to extract an image from the jar at runtime so I can then open it up? Or, is there a better way to do this?
I'd like to distribute a single jar file if possible.
To create an ImageIcon
from an image file within the same jars your code is loaded:
new javax.swing.ImageIcon(getClass().getResource("myimage.jpeg"))
Class.getResource
returns a URL of a resource (or null
!). ImageIcon
has a constructors that load from a URL.
To construct a URL for a resource in a jar not on your "classpath", see the documentation for java.net.JarURLConnection
.
