Each listing | |
| in the directory details the relevant email addresses and the name of the owner. GreenPages has only three screens: | |
| the search screen, the results screen and the listing detail screen.</p><p>In the search screen, users can enter search criteria to be matched against the listings in the directory. | |
| The result screen displays any listings that match the criteria entered by the user. The listing detail screen | |
| shows all the data known about a given listing.</p><p>Despite its simplicity, GreenPages is designed to demonstrate many different Virgo Tomcat Server features and to | |
| act as a template from which other modular applications can be built. In particular, GreenPages demonstrates: | |
