The steps to ensure that your installation is operational and running without problems are:
Enter the URL of the server into a browser, for example http://127.0.0.1, and you should see the Apache test page.
By opening a browser on the local machine and typing in the URL of your machine:8080, for example http://trillium.extraview.net:8080, you should get the default Apache Tomcat screen.
Now, append /evj/IsItEvj to the URL, for example http://localhost:8080/evj/IsItEvj and look for the following screen. You should see a screen that is equivalent, but with your installation details.
Now, type in the plain URL of your server, for example http://trillium.extraview.net. This will start ExtraView.
If you see the following screen, you will know that you have not configured the Apache configuration file httpd.conf properly.
