Apache Tomcat is a widely used Java application server with over million downloads per month. The wide success of Tomcat is due to its efficient, effective and light weight nature. Tomcat implements a servlet container and JSP, which is what majority of web applications depend on. Tomcat is not burdened by 20+ odd standards that form Java EE standard. As Apache Tomcat is not a Java EE engine, it can continue to stay light weight and meet the needs of web applications. While many other application servers came about in last decade, none have enjoyed the same level of success as Tomcat.
The current version of Apache Tomcat is 8.0 . Apache Tomcat powers numerous mission critical applications across a wide range of industries and organizations.

Tomcat is a servlet container. A servlet, at the end, is a Java class. JSP files (which are similar to PHP, and older ASP files) are generated into Java code (HttpServlet), which is then compiled to .class files by the server and executed by the Java virtual machine.
