Glassfish vs. Tomcat

Main Difference
Tomcat is merely an HTTP server and Java servlet container. Glassfish is full-blown Java EE application servers, including an EJB container and all the other features of that stack. Tomcat has a lighter memory footprint (~60-70 MB), while those Java EE servers weigh in at hundreds of megs. Tomcat is very popular for simple web applications, or applications using frameworks such as Spring that do not require a full Java EE server. Comparatively the administration of Tomcat server is more easier than administration of Glassfish as there are fewer moving parts in Tomcat.
