Glassfish vs. Tomcat: Know the Difference

By Shumaila Saeed || Updated on December 25, 2023

Glassfish is a full Java EE application server, while Tomcat is a web server and servlet container that can run Java servlets and JSPs.

Glassfish vs. Tomcat

Key Differences

Glassfish, developed by Oracle, is a fully-fledged application server supporting Java EE specifications, including EJB, JMS, and many more. Tomcat, developed by the Apache Software Foundation, primarily functions as a web server and servlet container, focusing on Java servlets and JavaServer Pages (JSP).

Dec 21, 2023

Glassfish is suitable for large-scale enterprise applications requiring full Java EE support. In contrast, Tomcat is often chosen for smaller-scale web applications that don't require the full Java EE stack, offering a lightweight solution.

Dec 21, 2023

The performance of Glassfish is optimized for full Java EE applications, potentially requiring more resources. Tomcat, being more lightweight, offers faster performance for web applications that only require servlets or JSPs.

Dec 21, 2023

In terms of community and support, Glassfish has the backing of Oracle and a robust community, offering comprehensive documentation and support. Tomcat, widely used in the industry, benefits from strong community support and a wealth of online resources.

Dec 21, 2023

Glassfish provides a more comprehensive set of features out of the box, including a complete administration console for easier management. Tomcat, while simpler, might require additional components for complex tasks but is easier to set up and manage for basic web applications.
