What is difference between Tomcat vs TomEE  ?

Tomcat and TomEE are both widely used Java-based web servers, but they serve different purposes. Apache Tomcat is an open-source Java servlet container that supports JavaServer Pages (JSP) and Servlet API. In contrast, Apache TomEE (pronounced "Tommy") extends Tomcat by adding support for Java Enterprise Edition (Jakarta EE) specifications.

In this article, we will compare Tomcat vs TomEE and highlight their features, differences, and use cases.

1. What is Tomcat?

Apache Tomcat is a lightweight, fast, and efficient Java web server designed for deploying web applications. It supports:

• Java Servlet API

• JavaServer Pages (JSP)

• Jakarta Expression Language (EL)

• Java WebSocket

• Java Annotations

Tomcat is ideal for running simple web applications that do not require the full Java EE stack.

2. What is TomEE?

Apache TomEE is an extended version of Tomcat that provides full Java EE (Jakarta EE) support. It includes additional components required for enterprise applications, such as:

• Java Message Service (JMS)

• Java Persistence API (JPA)

• Enterprise JavaBeans (EJB)

• Java Transaction API (JTA)

• Java RESTful Web Services (JAX-RS)

TomEE is suitable for applications that require enterprise-level features like transactions, security, and messaging.

1. Tomcat vs TomEE

• Tomcat is servlet container that supports servlet and JSP technology. TomEE is more extensive than Tomcat supporting many other Java EE technologies (specified by JSR-xxx).

Conclusion (tomcat vs tomee)

The Websites API and Java-Server Pages are two Java Enterprise Specs that are implemented by the open-source Java servlet container Tomcat.

Now we can distinguish between Tomcat and Tomee.

The Java Enterprise Edition of Apache Tomcat is known as Apache TomEE (pronounced "Tommy").

Tomcat vs tomee is compare based on feature .

Tomee includes the following open-source components:

Apache Tomcat :- HTTP server and Servlet container supporting Java Servlet and JavaServer Pages (JSP).
Apache OpenEJB :-Open-source Enterprise JavaBeans (EJB) container system.
Apache OpenWebBeans :- Open-source Java Persistence API (JPA) 2.1 implementation.
Apache OpenJPA :-Open-source Java Persistence API (JPA) 2.1 implementation.
Apache Geronimo Transaction :-Open-source Java Transaction API (JTA) 1.2 implementation.
Apache MyFaces :- Open-source Java Server Faces (JSF) implementation.
Apache ActiveMQ :-Open-source Java Message Service (JMS) implementation.
Apache CXF :- Web Services frameworks with a variety of protocols — such as SOAP, XML/HTTP, RESTful HTTP.
Apache Derby:- Full-fledged relational database management system (RDBMS) with native Java Database Connectivity (JDBC) support.
 

Conclusion: Tomcat vs TomEE

In summary, Tomcat is a lightweight web server ideal for small applications, whereas TomEE extends Tomcat with additional enterprise-grade features. Choosing between Tomcat and TomEE depends on the complexity of your application. If you only need a servlet container, Tomcat is sufficient. If you require full Java EE support, TomEE is the better choice.
