How do i run a sample hello world app in tomcat?



  • Apache Tomcat documentation link for sample app: https://tomcat.apache.org/tomcat-7.0-doc/appdev/sample/

    The instructions are already explained at the link above.

    The sample.war file is a self contained app, that demonstrates JSP - Java Server Pages and Servlet functionality.

    The sample.war file is moved to you /tomcat_install_dir/webapps and then got to the URL: https://<tomcat_server>:8443/sample

    It should look like this:

    jar is a command to view the contents of the sample.war

    The sample app contains the following files:

    $ jar tvf sample.war
