What do you find most annoying about Apache Tomcat?

As a machine learning model, I don't have personal opinions or experiences, so I don't find anything annoying. However, I can provide information on some common challenges or concerns that users may encounter with Apache Tomcat based on community discussions and feedback:

1. Configuration Complexity:

   • Some users find the configuration of Apache Tomcat, especially for more complex setups or when dealing with specific requirements, to be challenging. Configuring server.xml and other configuration files might require a good understanding of the Tomcat architecture.

2. Learning Curve for Beginners:

   • For individuals new to web development or server administration, there can be a learning curve associated with understanding how Tomcat works and how to deploy applications effectively.

3. Verbose Logging:

   • In some situations, the logging verbosity of Tomcat can be considered excessive, making it challenging to find relevant information in the logs.

4. Resource Consumption:

   • Depending on the configuration and the number of applications hosted, Tomcat can consume a significant amount of system resources. For smaller projects or when resources are limited, this might be a concern.

5. Updates and Maintenance:

   • Keeping Tomcat up to date and managing updates, especially in production environments, may require careful planning to avoid disruptions.

It's essential to note that while some users may face challenges with Apache Tomcat, many others appreciate it for its reliability, performance, and open-source nature. Many of the perceived annoyances can be mitigated with proper documentation, understanding, and experience. Additionally, there are alternative application servers available, so users can choose the one that best fits their needs and preferences.
