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 of HTML, XSLT, and CSS files.
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 its 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). Each file, in its location, is required by Hyrax. You can make changes to the files but you should not rename or remove them. |
|
Note
|
Beacuse nothing inside the $CATALINA_HOME/content directory is (automatically) changed when installing new versions of Hyrax, changes you make to files in the content directory will persist when you upgrade Hyrax. |
The rest of these instructions are written with the assumption that a copy of the docs directory has been made as described above.
| File | Location | Description |

index.html |
$CATALINA_HOME/content/opendap/docs |

contents.css |
$CATALINA_HOME/content/opendap/docs/css |
The contents.css style sheet provides the default colors and fonts used in the Hyrax site. It is referenced by all of the HTML and XSL files to coordinate the visual aspects of the site. |
thredds.css |
$CATALINA_HOME/content/opendap/docs/css |
The thredds.css style sheet provides the default colors and fonts used by the THREDDS component of Hyrax. |
There are a number of image files shipped with Hyrax. Simply replacing key image files will allow you to customize the icons and logos associated with the Hyrax server.
| File | Location | Description |
|---|---|---|
logo.gif |
$CATALINA_HOME/content/opendap/docs/images |
Main Logo for the directory view (produced by contents.css and contents.xsl) |
favicon.ico |
$CATALINA_HOME/content/opendap/docs/images |
The cute little icon preceding the URL in the address bar of your browser. To be used, this file needs to be installed into Tomcat. |
BadDapRequest.gif, BadGateway.png, |
$CATALINA_HOME/content/opendap/docs/images |
These files are referenced by the default collection of web content files (described above) that ship with Hyrax. |
These files are used to transform XML documents used by Hyrax. Some transforms operate on source XML from internal documents such as BES responses. Other transforms change things like THREDDS catalogs into HTML for browsers.
|
Warning
|
All of these XSLT files are software and should be treated as such. They are intimately tied to the functions of Hyrax. The likelihood that you can change these files and not break Hyrax is fairly low. |
| File | Location | Description |
|---|---|---|
catalog.xsl |
$CATALINA_HOME/content/opendap/docs/xsl |
The catalog.xsl file contains the XSLT transformation that is used to transform BES showCatalog responses into THREDDS catalogs. |
contents.xsl |
$CATALINA_HOME/content/opendap/docs/xsl |
The contents.xsl file contains the XSLT transformation that is used to build
the OPeNDAP
Directory Response |
dataset.xsl |
$CATALINA_HOME/content/opendap/docs/xsl |
This transform is used to in conjunction with the opendap.threddsHandler code to produce HTML pages of THREDDS catalog dataset element details. |
error400.xsl |
$CATALINA_HOME/content/opendap/docs/xsl |
The error400.xsl contains the XSLT transformation that is used to build the web page that is returned when the server generates a Bad Request (400) HTTP status code. If for some reason this page cannot be generated, then the HTML version ($CATALINA_HOME/content/opendap/docs/error400.html) will be sent. |
error500.xsl |
$CATALINA_HOME/content/opendap/docs/xsl |
The error400.xsl contains the XSLT transformation that is used to build the web page that is returned when the server generates a Internal Server Error (500) HTTP status code. If for some reason this page cannot be generated then the HTML version ($CATALINA_HOME/content/opendap/docs/error500.html) will be sent. |
thredds.xsl |
$CATALINA_HOME/content/opendap/docs/xsl |
This transform is used to in conjunction with the opendap.threddsHandler code to produce HTML pages of THREDDS catalog details. |
