This happens once per unique attribute on each request (or per JSP/tag context) accessing the same attribute again in the same context does not lead to additional class lookups. and no such attribute is defined in the view model), there are class loader calls to find the classes " java.lang.", " rvlet.", " ." and " .". Starting with Spring Boot 2.3.0, the following happens: For each non-existing attribute accessed during Spring EL expression evaluation on a JSP (for example, when using $ or. This problem seems to affect all current versions of Spring Boot 2.3.x (2.3.0 to 2.3.7) and 2.4.x (2.4.0 and 2.4.1), but not 2.2.x. In conclusion, there is very little you can do with GlassFish that you can’t do with Tomcat.We have noticed that JSP EL expression evaluation has become significantly slower when non-existing attributes are accessed, starting with Spring Boot 2.3.0. While Glassfish is the reference implementation of the Java EE standard (which includes Servlet and JSP). Tomcat being the reference implementation for the Servlet and JSP specification.
#Difference between tomcat and glassfish license
Tomcat has a single license whereas GlassFish has dual license.įinally, they are reference implementations for various Java standards.

This ensures easy deployment via continuous integration service such as Jenkins.Īs mentioned before, they are both open source and free but with different licenses. Subsequently, both are supported and compatible with build tools such Maven and Ant. This alone eases deployment, testing and change management that may occur during development.
Basically, you’re looking at around a 60MB to 70MB memory footprint whereas Java EE servers like GlassFish need hundreds of megabytes in memory just to get started.Ĭlick here to access this GlassFish vs Tomcat – Quick Round-Up?īe that as it may, both servers are popular with Integrated Development Environments (IDEs) such as Eclipse and NetBeans. However, if you’re building a web application with Servlets and JSP you may want to use Tomcat because using GlassFish may be an over-kill.Īnother aspect in GlassFish vs Tomcat comparison is that Tomcat has a lighter memory footprint. However, bear in the mind it can’t handle EJB components like GlassFish does. Nevertheless, a lot of deveopers gravitate towards it over the likes of GlassFish because of its simplicity of operation, ease of maintenance, rapid startup and deployment and minimal over-head. Unlike “heavyweight” Java EE application servers like GlassFish or JBoss. Traditionally, it’s viewed as a “lite” version of Java EE since that it serves as a web server and a Servlet container. Given that it has fewer moving parts unlike GlassFish, Tomcat is much easier to manage and administer. It literally powers 63.8% of Java related web application deployments according to the same Plumbr.io report mentioned above. Tomcat is very popular among developers as well as organizations for simple applications compared to GlassFish. It uses the Apache license whereas Glassfish is licensed under CDDL and GPL. It is supported by the Apache community and does not have any commercial support.

Likewise it’s open source and maintained by the Apache Software Foundation. As a servlet container, it’s a component of the web server that interacts with Java Servlets and implements the Servlets and JSP specification. On the the hand, Tomcat is a web container (a.k.a servlet container) and HTTP server. Also, essentially it has its own web container (a derivative of Tomcat) and thus shares the same Catalina servlet container with Tomcat. In addition to being an open source reference implementation of Java EE application server GlassFish comes packed with core Java EE technologies such as: Servlets, Enterprise Java Beans (EJBs), Java Persistence API (JPA), JavaServer Faces (JSF), Java Message Service (JMS) as well as the default Java EE SDK.įurthermore, in addition to being a Java EE application server, GlassFish handles EJB requests thus is also an EJB Container. GlassFish is the Open Source reference implementation for a Java EE application server. It’s this specification that all further implementations and corresponding customizations are based on.
