What is Apache Tomcat, Do I need install?

[Nirjonadda]

Good morning, all ... I have a questions, What is Apache Tomcat, Do I need install? Apache Web Server and Apache Tomcat: Do I need both?

As i know Xenforo or Elasticsearch are not required Tomcat but Elasticsearch required Java. So does need Installing Tomcat for Java libraries?

Thanks

Apache tomcat is for hosting Java applications. You do not need Tomcat to run XenForo or Elasticsearch. Elasticsearch only needs java, not Tomcat
