Cannot access resource by using the getResources()

Question

I have the following project-tree:

I can access the 290.gif file in the path: Java GUI/src/dk/resources/290.gif by using the following command:

this.getClass().getResource("/dk/resources/290.gif")

But I can't access the 290.gif file in the path: Java GUI/resources2/290.gif by using the following command:

this.getClass().getResource("/resources2/290.gif")

I am trying to access the 290.gif file from the HelloWorldFrame.java class. I want to access the 290.gif file in the path: Java GUI/resources2/290.gif!

What am I doing wrong?

Answer 1

Seems that the folders src and resources2 are both in the build path. Have you tried this.getClass().getResource("/290.gif")?

Answer 2

During runtime of the artifact you can access resources with

InputStream resource = SomeClass.class.getResourceAsStream("<file or directory name"))

or

URL resource = SomeClass.class.getResource("<file or directory name"))

where SomeClass is a class in the artifact. The first way will give you an InputStream that you can use to read the contents of the file, the second way will return a URL that you can use to find out the path of the file or directory or move along the directory tree.

Answer 3

You have declared both src and resources2 directories as source folders in Eclipse. When Eclipse builds your app, it copies recources to the build folder, and so:

• the files from dk.resources package are accessible via /dk/resources/290.gif
• the files from resources2 folder are not in any package, and are accessible via /290.gif

If you want the file to be accessible via /resources2/290.gif, then create a package named resource2 under the src folder.
