This is the example project referred to in the Struts 2 documentation, JasperReport tutorial.
To build the application‘s war file run mvn clean package
from the project’s root folder.
The war file is created in the target sub-folder.
Copy the war file to your Servlet container (e.g. Tomcat, GlassFish) and then startup the Servlet container.
Or if you are using maven you can run command:
mvn jetty:run
