Trouble working with Data Grid Getting Started examples

Hello, I am having issues working with the grid examples provided in http://apacheignite.readme.io/v1.0/docs/getting-started I have the following code in main.java (modified for Java6): ```java import org.apache.ignite.Ignite; import org.apache.ignite.IgniteCache; import org.apache.ignite.Ignition; public class IgniteGettingStarted { public static void main(String[] args) { final String CACHE_NAME = IgniteGettingStarted.class.getSimpleName(); try { Ignite ignite = Ignition.start("examples/config/example-cache.xml"); IgniteCache<Integer, String> cache = ignite.cache(CACHE_NAME); // Store keys in cache (values will end up on different cache nodes). for (int i = 0; i < 10; i++) cache.put(i, Integer.toString(i)); for (int i = 0; i < 10; i++) System.out.println("Got [key=" + i + ", val=" + cache.get(i) + ']'); } catch (Exception e) { e.printStackTrace(); } } } ``` When running the main method I get the following error: ``` 11:29:03,775 INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from URL [file:/home/nltran/ignite-fabric-1.0.0-incubating/examples/config/example-cache.xml] 11:29:04,015 INFO org.springframework.context.support.GenericApplicationContext - Refreshing org.springframework.context.support.GenericApplicationContext@1936f0f5: startup date [Wed May 06 11:29:04 CEST 2015]; root of context hierarchy [11:29:04] __________ ________________ [11:29:04] / _/ ___/ |/ / _/_ __/ __/ [11:29:04] _/ // (7 7 // / / / / _/ [11:29:04] /___/\___/_/|_/___/ /_/ /___/ [11:29:04] [11:29:04] ver. 1.0.0#20150329-sha1:5fc2cd05 [11:29:04] 2015 Copyright(C) Apache Software Foundation [11:29:04] [11:29:04] Quiet mode.
