java, loading of resources fails: unable to resolve file:/my-jar.jar!/folder/my-file

Question

From a java application i made, I build the corresponding jar file.

I copy all the resources in the jar file.

For example, if in src/main/resources

Answer 1

In that case, I would try:

YourClass.class.getClassLoader().getResourceAsStream("folder/my-file");

Which would return an InputStream to your resource independently of your execution environment .

Answer 2

if you have an structure like this:

src/main/Begin.java
src/main/folder/icon.png

Try this in the Begin.java:

  Begin.getClass().getResource("/main/folder/icon.png");
