Hi Beth.
I think the best place to start with is to make sure that you're Viewer installation is working.
Just as some background, the modelling tools in Protege communicate with the Viewer when you do a publish, so if there's something wrong with the Viewer, the Essential Architecture Reporting Tab will report an error.
The initial installation of Essential Viewer includes a baseline repository, so that we can check all is OK before we do any publishing from Protege.
Some questions?
- Are you running in stand-alone mode? That is, you have the whole Essential Architecture Manager installation running on a single computer, e.g. your laptop or workstation?
- Or are you running in a multi-user mode? That is, the Essential Viewer and the Essential Repository are installed on a server that you are accessing over the network?
If you're running standalone, you can use 'localhost' in the following URLs I'm going to quote and if you're running in multi-user (client-server) you use the hostname of the server that Essential Viewer is installed on in the following URLs.
So, to check that Viewer is installed correctly, open a web browser and enter the following URL:
Code: Select all
http://<hostname>:8080/essential_viewer
e.g.
Code: Select all
http://localhost:8080/essential_viewer
This article contains a bit more information about how to
get started with the Viewer.
If the Viewer is installed properly, you'll see the default homepage for Essential Viewer. See the above
Viewing Your Architecture Model article for some screenshots of what you should see.
If, however, you get any error message, then there's a problem with the installation of the Viewer.
If the browser returns an error about the server not being available or could not connect to server, check that Tomcat (or your favourite alternative Java Web Application Server) is running. On Windows, go to the Manage Tomcat system tray icon, right-click and select Start. You may have to start the Monitor / Manage Tomcat tray element from the Start Button->Programs->Apache Tomcat.
If you are getting a 404 message from Tomcat, then it running but there's a problem with the installation of the Essential Viewer application.
Hopefully, these checks will give us a clearer idea of what's not working on your install. Could you let me know what platform you're running on? (e.g. Windows Vista, Windows 7, Mac OS/X)
Let me know how you get on with the above, and if there's still a problem or it appears that Essential Viewer is not installed properly, let me know what you're seeing and we can take it from there.
