Apache TomEE
Apache TomEE is a lightweight, all-in-one Java EE (now Jakarta EE) application server that combines the Apache Tomcat web server with additional enterprise features. It provides a certified Java EE Web Profile or Full Profile implementation, enabling developers to build and deploy enterprise Java applications with minimal configuration. TomEE integrates seamlessly with Tomcat, offering enhanced capabilities like EJB, JPA, CDI, and JAX-RS out of the box.
Developers should use Apache TomEE when building enterprise Java applications that require Java EE/Jakarta EE standards compliance without the overhead of heavier servers like JBoss or WebSphere. It is ideal for microservices, web applications, and RESTful APIs where a lightweight, Tomcat-based environment with full enterprise support is needed. TomEE simplifies deployment by bundling necessary components, reducing setup time and complexity compared to configuring Tomcat with separate EE modules.
