Apache Tomcat Reviews & Product Details

Apache Tomcat is an open-source implementation of the Jakarta EE platform's core specifications, including Jakarta Servlet, Jakarta Pages, Jakarta Expression Language, Jakarta WebSocket, Jakarta Annotations, and Jakarta Authentication. Developed and maintained by the Apache Software Foundation, Tomcat provides a "pure Java" HTTP web server environment for running Java code, making it a robust and reliable solution for deploying Java-based web applications. Key Features and Functionality: - Servlet Container (Catalina): Catalina is Tomcat's servlet container that implements the Jakarta Servlet specification, enabling the execution of Java Servlets. - JSP Engine (Jasper): Jasper is the JSP engine that compiles JavaServer Pages into servlets, facilitating dynamic web content generation. - HTTP Connector (Coyote): Coyote is the HTTP connector component that supports HTTP/1.1 and HTTP/2 protocols, allowing Tomcat to function as a standalone web server. - WebSocket Support: Tomcat provides support for the Jakarta WebSocket specification, enabling real-time, bi-directional communication between clients and servers. - Security Realms: Tomcat includes configurable security realms for user authentication and authorization, enhancing application security. Primary Value and User Solutions: Apache Tomcat offers a lightweight, efficient, and scalable platform for deploying Java-based web applications. Its adherence to Jakarta EE standards ensures compatibility and portability across different environments. Tomcat's modular architecture allows developers to integrate it seamlessly into existing infrastructures, whether as a standalone server or in conjunction with other web servers. Its open-source nature and active community support provide continuous improvements, security updates, and a wealth of resources for troubleshooting and development. By using Tomcat, organizations can deploy robust, high-performance web applications while maintaining flexibility and control over their server environments.

"Transparent, Lightweight Apache Tomcat with Clear Logs and Readable Config"

5/5

What do you like best about Apache Tomcat?

What I like most about Apache Tomcat is how transparent it feels. When something breaks, I can actually trace it: the logs are clear, the configuration files are readable, and nothing feels “hidden” behind heavy abstraction. Review collected by and hosted on G2.com.

What do you dislike about Apache Tomcat?

What I dislike about Apache Tomcat is that it can sometimes feel a bit too minimal. Even though its lightweight nature is a big plus, I often end up having to manually configure things that are built in with full application servers—such as advanced security features, clustering, or enterprise-level monitoring. Review collected by and hosted on G2.com.

What problems is Apache Tomcat solving and how is that benefiting you?

Apache Tomcat solves the problem of running Java web apps easily, without needing a heavy application server.

For me, it makes deployment straightforward, keeps resource usage low, and gives me better control when troubleshooting. It focuses on what’s needed and avoids unnecessary complexity. Review collected by and hosted on G2.com.

"Lightweight, Fast, and Easy Java App Deployment with Apache Tomcat"

4.5/5

What do you like best about Apache Tomcat?

1. I have used Apache Tomcat as web server and its Lightweight & easy to setup on any environment i.e windows or unix based system.

2. Low infrastructure requirement for installation and configuration. So the developers can quickly deploy the static web apps and jsp/servlets.

3. Startup time is superfast and application is up and running within few seconds.

4. Apache tomcat is open source, so we don't need to worry about the subscription and cost initially.

5. Community support is appreciated.

6. I use this web server mostly on weekly basis and easy to debug for any issues. Review collected by and hosted on G2.com.

What do you dislike about Apache Tomcat?

1. Support for JavaEE apps is unavailable

2.The UI/UX of the manager pages are developed with simple UI and lagging modern web apps capabilities.

3. Not suitable for large scale apps Review collected by and hosted on G2.com.

What problems is Apache Tomcat solving and how is that benefiting you?

So, we have a lot of in-house lightweight applications requirement where Apache tomcat fits well for deployment. We are able to develop and deploy some static apps and java (jsp & servelets) apps. Considering the lifespan of the lightweight applications short, Apache Tomcat serves the purpose well. Review collected by and hosted on G2.com.
