Okey, I tried with Tomcat, and it works, it seems that is Glassfish related problem, but I want to use Glassfish as server, since I use EJB in my projects.
It's a bug inside Eclipselink: https://bugs.eclipse.org/bugs/show_bug.cgi?id=463169 , try upgrading to the latest version?
I am getting following error while starting my application:
SEVERE: Exception starting filter CSRF
java.lang.ClassNotFoundException: org.apache.catalina.filters.CsrfPreventionFilter
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
Tried to find jar for org.apache.catalina.filters.CsrfPreventionFilter on findjar.com but could not find anything.
You should check your tomcat installation, since this is a tomcat class.

How can i resolve this issue?
It means just what it says: you don't have the Mahout classes included in your web app! put the JAR files in WEB-INF/lib as you need to do with any other library a web app needs.
