How Tomcat is configured internally?

Tomcat receives a request from a client through one of its connectors. If it has not, Tomcat compiles the servlet into Java bytecode, which is executable by the JVM, and creates an instance of the servlet. Tomcat initializes the servlet by calling its init method.

Does Tomcat run on JVM?

Apache Tomcat is a Java servlet container, and is run on a Java Virtual Machine, or JVM. Tomcat utilizes the Java servlet specification to execute servlets generated by requests, often with the help of JSP pages, allowing dynamic content to be generated much more efficiently than with a CGI script.

How does Tomcat deployment work?

Java web applications are usually packaged as WAR files for deployment. These files can be created on the command line or with an IDE, like Eclipse. After deploying the WAR file, Tomcat unpacks it and stores all the project files from the webapps directory in a new directory named after the project.

How does a web server work internally?

At the most basic level, whenever a browser needs a file that is hosted on a web server, the browser requests the file via HTTP. When the request reaches the correct (hardware) web server, the (software) HTTP server accepts the request, finds the requested document, and sends it back to the browser, also through HTTP.

How does Tomcat process a request?

Tomcat contains pool of threads to handle multiple HTTP requests. For each request tomcat assigns a thread from its pool to handle request. When the response has been generated and sent back, this thread gets free and ready to serve another request.

What is GC in tomcat?

GC is a function of the JVM (not specific to tomcat) and can be adjusted according to the docs for the particular flavor/version of java that you’re using. IMO, most modern apps on modern java shouldn’t need GC tuning provided that you’re not doing something like starving the JVM for memory (87\% is getting up there).

What is Apache vs tomcat?

Key difference between Tomcat and the Apache HTTP Server the Apache HTTP Server, but the fundamental difference is that Tomcat provides dynamic content by employing Java-based logic, while the Apache web server’s primary purpose is to simply serve up static content such as HTML, images, audio and text.

How do war files work?

The WAR file is simply a JAR file (which is itself a fancy ZIP file) with specified directories for the Java code and one designated configuration file: the web. xml file, which tells the application server what to run and how to run it. WAR files always have the extension .
