Hello everyone. I hope I did everything right to subscribe to this mailing
list, it's the first time I join one.
First of all, please forgive any mistakes you'll probably see in my mail,
I'm not a native speaker.
I'm seeking some help with GeoTools. I've been using it for a school's
project, I had almost no problem until now.
But now that my project is done, I've tried to build an executable jar with
the maven's shade plugin like it is shown in the GeoTools' FAQ.
Here's my problem, when I try to use the jar which have been created when I
type 'mvn package', I get this error :
> java.lang.UnsupportedOperationException: Trying to get a reader from an
> unknown
> format.

> at coeur.Interface.getMapsAndDisplay(Interface.java:162)
> at coeur.Interface.<init>(Interface.java:948)
> at coeur.Interface.main(Interface.java:957)
It happens when I try to read a GeoTif file with the method
"reader.read(null)".
Of course I don't have this problem when executing the project on Eclipse.
I read somewhere that it could be a dependency problem, but I don't see
what I could have missed.
Some details which could be helpful :
- I'm using GeoTools version 12-RC1
- I'm not using the JAI libraries, I'm working in Java Pure mode. It allows
me to work with a 64 bits jdk. I tried by curiosity with a 32bit jdk, but I
still have the same problem anyway.
- I'm working on Windows 7, but it shouldn't make any difference.
Here's the content of my pom.xml :

I'd be very grateful if someone can help me to solve this problem. I need
this executable jar to finish my project and I don't have a lot of time to
get it.

Valentin
