Playing with Apache TomCat


Apache TomCat or simply TomCat should not be confused with Apache web server. They are not bundled together but it is another fact that they are used together frequently. Apache TomCat is an open source servlet container developed by the Apache Software Foundation. Tomcat implements the Java Servlet and the JSP specifications to provide a "pure Java" HTTP web server environment for Java code to run.
