Load from resource from within a servlet

[michelwilson]

I'm trying to load resources from the classpath in a servlet application. I would expect to be able to use

ConfigurationProperties.fromResource("application.properties")

or maybe

ConfigurationProperties.fromResource(SomeClass::class.java, "application.properties")

But both don't work. The first uses the system classloader, instead of the servlet classloader (which makes sense), but the second variant should work. In the code I see that the class that is passed in is used like this:

relativeToClass.getResource(resourceName)

For some reason this doesn't work. What does work is

relativeToClass.classLoader.getResource(resourceName)

Since I cannot passin the URL returned from this call, I have to resort to

val res = SomeClass::class.java.classLoader.getResource("application.properties")
ConfigurationProperties.fromFile(File(res.file))

Which isn't very elegant. Am I missing something here?
