GRAVE: Servlet [Jersey REST Service] in web application [/arena] threw load() exception java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1332) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1166) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:518) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:499) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:118) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1102) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:1038) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:5027) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5337) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:147) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1407) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1397) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
