Customization and flexibility enhance web applications while support effectively resolves queries
Regarding improvements in Tomcat, I personally haven't used it very extensively, but all Apache products are very useful for our web applications. Although the web server setup is a little different, it has everything we have been using, and as of now, everything is good with no deficiencies that need improvement. I think that Tomcat needs a more robust logging error details feature; the current logging feature is available, but it should be more user-friendly. This improvement would make error handling more user-friendly.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product offers EE support."
"The products offers EE support."
"Tomcat is user-friendly and easy to set up, especially compared to WebLogic or JBoss where some specialty is required. If you are going for Tomcat, you can use their guidelines and can set it up easily."
"It's very stable. No problems at all. I would rate the stability a ten out of ten."
"From these experiences I can say that Tomcat is a really performing and PRODUCTION ready server."
"Web apps are very easy to deploy."
"The most valuable feature is how simple it is to deploy the solution."
"The product's initial setup phase was simple."
"Tomcat's ease of use has positively impacted project timelines. Tomcat already has high availability – it doesn't go down so often and doesn't require a lot of maintenance. As long as your application works, you can depend on Tomcat."
"Lightweight Configurable High-performance Cross-platform Open source It has sufficient documentation for application development"
 

Cons

"I would like to see integration with MQ systems."
"I would like to see integration with MQ systems."
"It will be useful if a direct report concerning a particular server configuration or application usage is readily available in the dashboard."
"The disability and memory management is a problem with the solution and has room for improvement."
"The solution cannot host .NET applications."
"Out-of-Memory issues, which can be solved by increasing the heap space."
"Security integration in Tomcat is complicated. We need to use another tool to solve the security issues."
"Tomcat is used mainly for database connections. As of now, we configure that environment for any database configuration. But if any utility can integrate where we can pass the database connection as a string of details, then it should encrypt them and keep them inside. From that security perspective, Tomcat requires improvement. They should integrate this security feature."
"Tomcat is a polished product that has been around for a long time. It should be simple and high-performing, with the ability to grow and maintain stability. The fewer features it has, the more stable it will be."
"Security integration in Tomcat is complicated. We need to use another tool to solve the security issues."

What needs improvement with Tomcat?
Tomcat lacks a visual tool for configuring. Everything is from the command line. I would like a visual tool for configuration to be added to Tomcat, as I see this feature missing.
What is your primary use case for Tomcat?
