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 products offers EE support."
"The solution has very robust functionality."
"We can use Apache Tomcat for Java server applications."
"It allows rapid application deployment for Java web container applications."
"The solution is readily available and open-source."
"Tomcat is a single-server solution for deploying applications that can scale effectively. It's a good choice because it simplifies deployment. Once you package your application, deployment is straightforward and efficient."
"The deployment process is very fast."
"Tomcat is reliable and secure, which makes it valuable for our application deployment."
"I like the solution’s ease of use."
 

Cons

"I would like to see integration with MQ systems."
"Vulnerability is one of the areas that can be considered an issue in the solution."
"If it could support the driver's VIN, they can run natively without the GBM. Now, we can run what we call the native cloud application that doesn't require GBM. If Tomcat can support that, it's going to improve performance and backup."
"Scalability is a major problem with Tomcat."
"It will be useful if a direct report concerning a particular server configuration or application usage is readily available in the dashboard."
"The high availability is not as robust as the competition is, such as WebLogic and Jboss."
"Java functions should be built better into the solution."
"Performance optimization is an area of concern in Tomcat that should be made better."
"Out-of-Memory issues, which can be solved by increasing the heap space."

I work with Tomcat as a programmer, but not as an administrator. My major use case involves using Tomcat, mostly enclosed in any Java image for a Java application for REST API. I do not work with t...
What is your experience regarding pricing and costs for Tomcat?
I am familiar with pricing for Tomcat. For me, it is open source. Since it is open source, I don't see any fee for that regarding whether the license for Tomcat is usually expensive or quite afford...
