Hyrax - Customizing Hyrax
There are several ways in which Hyrax can be customized:
- Web interface look and feel can be changed, as can the pages served.
- Custom DispatchHandlers for the OLFS
- Custom RequestHandlers for the BES.
Web page customization
Hyrax's public "face" is the web pages that are produced by servlets running in the Tomcat servlet engine. Almost all of these pages can be completely customized by the site administrator by editing a combination HTML, XSLT, and CSS files.
Where to make the changes
All of the default versions of the HTML, XSLT, and CSS files come bundled with hyrax in the $CATALINA_HOME/webapps/opendap/docs directory. You can make changes there, but installing new versions of the OLFS software will overwrite your modifications.
However, if the docs directory is copied (preserving it's structure) to $CATALINA_HOME/content/opendap/ (creating the directory $CATALINA_HOME/content/opendap/docs), then Hyrax will serve the files from the new location.
- Warning
- Do NOT remove files from this new directory (Or the old one for that matter). Each file, in it's location, are required by Hyrax. You can make changes to the files but you should not rename or remove them.
Nothing inside the $CATALINA_HOME/content directory is (automatically) changed when installing new versions of Hyrax.
The rest of these instruction are written with the assumption that a copy of the docs directory has been made as described above.
What to change

The HTML files provide the static content of a Hyrax server.
File | Location | Description | ||
index.html | $CATALINA_HOME/content/docs | The documentation web page for the top level of Hyrax. As shipped it contains a description of Hyrax and links to documentation and funders. The contents.html pages (aka the OPeNDAP directories) links to this document. | ||
error400.html | $CATALINA_HOME/content/docs | Contains the default error page that Hyrax will return when the clients request generates a Bad Request error (Associated with an HTML status of 400) | ||
error403.html | $CATALINA_HOME/content/docs | Contains the default error page that Hyrax will return for when the clients request generates a Forbidden error. (Associated with an HTML status of 403) | ||
error404.html | $CATALINA_HOME/content/docs | Contains the default error page that Hyrax will return for when the clients request generates a Not Found error. (Associated with an HTML status of 404) | ||
error500.html | $CATALINA_HOME/content/docs | Contains the default error page that Hyrax will return for when the clients request generates an Internal Server Error. (Associated with an HTML status of 500) | ||

Image Files
There are a number of image files shipped with Hyrax. Simply replacing key image files will allow you to customize the icons and logo's associated with the Hyrax server.
File | Location | Description | ||
logo.gif | $CATALINA_HOME/content/docs/images | Main Logo for the directory view (produced by contents.css and contents.xsl) | ||
favicon.ico | $CATALINA_HOME/content/docs/images | The cute little icon by preceding the URL in the address bar of your browser. To be used this file needs to be installed into Tomcat as described here | ||
BadDapRequest.gif, folder.png, forbidden.png, largeEarth.jpg, nasa-logo.jpg, noaa-logo.jpg, nsf-logo.png, smallEarth.jpg, sml-folder.png, superman.jpg |
