访问 Jar 中的 .jpg 文件

Question

I have a question about accessing a.jpg file that is contained within a ant generated java jar file. My java project contains Java code and some.jpg files that I use. I want to be able to reference that.jpg file and be able to copy from jar to a directory.

Is there any way to that or do I always have to keep the jar outside of the jar file?

Answer 1

You can import the jar as a library into your project and access the resources directory or wherever you placed the JPG if you want to reference it directly from your project.

Answer 2

Jar files are just.zip's with a manifest. If you know where in the jar file the jpg is place, you just need to unzip the jar and copy the jpg to the desired location.
