Ok, I have Jetspeed more or less up and running, and am now in the
phase of finding out what it can really do, and how we can use it for
our portals. If this information is of use to anybody, please add it
wherever it should go.
Jetspeed can show several different kinds of information. For
example, the default page has the following areas, defined in
default.psml:
* Jetspeed: Its parent is JetspeedContent, which is a portlet for
static news taken from a XML file called jetspeed-content.xml.
* Apache Jetspeed: Its parent is Jetspeed, whose parent is RSS, which
is a portlet that shows RDF information. The source for this is an
XML file called Jetspeed.rss.
* Applications: Its parent is Applications, which is a portlet that
encapsulates a whole application inside a portlet. This portlet will
contain any portlets that have set the property application to
"true".
* Search: Its parent is Search, whose parent is FileServer, which is a
portlet that seemingly shows the contents of a static HTML file. In
this case, the file shown is static/search.html; this file even has
Javascript code to show icons for different search engines.
* Slashdot: Its parent is Slashdot, whose parent is RSS. So this
should work just like Apache Jetspeed, but based on the contents of
http://www.slashdot.org/slashdot.rdf. It looks like it is expected
that this URL will provide its contents in the RDF format.
* Apacheweek: Its parent is Apacheweek, whose parent is RSS. This is
identical to Slashdot, but the URL now is
http://www.apacheweek.com/issues/apacheweek-headlines.xml.
The links that SHOULD be shown on my default screen, but are not:
* Mozilla: Its parent is Mozilla, whose parent is RSS. This is
identical to Slashdot, but the URL now is
http://www.mozilla.org/news.rdf. The log prints this error message:
RSSPortlet: Couldn't parse out XML document ->
http://www.mozilla.org/news.rdf
So it seems this site is not exporting its items in the proper
format (or there is a bug in Jetspeed...).
* XMLHack: Its parent is XMLHack, whose parent is RSS. This is
identical to Slashdot, but the URL now is
http://www.xmlhack.com/rss.php. The log prints this error message:
RSSPortlet: Couldn't parse out XML document ->
http://www.xmlhack.com/rss.php
So it seems this site is not exporting its items in the proper
format (or there is a bug in Jetspeed...).
There are several other kinds of information that are not used on the
default page:
* PortletBrowser, parent Cocoon.
* PortletSearch, parent Cocoon.
* Customizer, parent Cocoon.
* XSPApplication, parent Cocoon.
* Cocoon: This portlet runs a generic XML file (program) through
Cocoon. Each portlet above sets its own file to be run.
* PortletInfoPortlet: This portlet shows information about other
portlets.
There are eight other portlets that I know exist but don't know
anything about:
* GlobalAdminPortlet
* SelectPortlet
* JetspeedPropertiesPortlet
* MemoryStorePortlet
* JavaRuntimePortlet
* DaemonAdminPortlet
* JetspeedContentAdmin
* BadURLManagerPortlet
Open questions, that I hope someone will be able to answer:
* What is RDF?
* Why is there a JetspeedContent portlet and a RSS portlet? I'm not
sure the format for jetspeed-content.xml is RDF, but they seem to
serve the same purpose... Or not?
* How does the layout work? What are the different ways of laying
things out on a page? By column, by row, randomly (8-)?
* How should one change colors, look and feel, etc., for the whole
portal?
* What are the little "edit" and "<square>" buttons on top of each
area? Can one hook onto them to do something else? Can one add other
buttons to the yellow title lines?
Thanks,
