Trouble reading resource files

[Yaron Rosenbaum <ya...@whatson-social.com>]

Hi

I'm trying to read resource files in one of my bolts.
The resource files reside under '/profiles' within my JAR (verified).

I'm using com.google.common.io.Resources like this:
URL profilesUrl = Resources.getResource("profiles");
The returned URL (.toString) equals :jar:file:/Users/.../storm/target/storm-1.0-SNAPSHOT.jar!/profiles

Same result with:
URL profilesPath = Thread.currentThread().getContextClassLoader().getResource("profiles");

Note the exclamation point (!) after '.jar'.
This is of course a malformed URL, which results in a MalformedUrlException when I try to use this URL to open a file (a folder in my case).

Searching through stackOverflow, I've seen cases where people recommended using .getResourceAsStream for a file within a jar, but unfortunately the library that I'm using requires the path string of the resource, and not a stream.

Obviously people are reading resource files while using Storm, so I must be doing something wrong.

Thank you
(Y)

This is not a Storm issue but a Java one, and you should definitively use
'getResourceAsStream' since you file is not a file: it's included in a JAR
hence the ! in the URL.
A solution is to extract this resource in a temporary file then use it.
