We are currently looking for a way to enable ajax requests and file
downloads with jetspeed-2 inside the security context of jetspeed. We
have looked at the different pipelines and got some things to work but
it is very hacky. Several things remain unclear to allow us to
implement
a clean solution.
First question is how to build an url to a different pipeline?
Jetspeed has two pipelines that may be of use:
1. Ajax Pipeline
2. File Server Pipeline
see:
http://portals.apache.org/jetspeed-2/guides/guide-ajax-api.html
If you install the demo, you can see an example of the file server
pipeline at:
http://localhost:8080/jetspeed/fileserver/_content/sample_pdf.pdf
Standard ways of building an url with <portlet:someURL /> or
RenderResponse.createSomeURL() do not allow one to specify a different
base url. From a portlet page that was requested as
www.host.com/jetspeed/portal/blablabla using standard url utilities
results in a www.host.com/jetspeed/portal/blablabla url while I would
wish to have a www.host.com/jetspeed/fileserver/blablabla url. Is this
possible?
Yes, see the Jetspeed Desktop, we do both render and action requests
using two pipelines:
DesktopPipeline
see pipelines.xml for all available valves and pipelines configured by
Spring
DesktopActionPipeline
Granted this will take some javascript code on your part to implement
your own Desktop functionality
The current hack in use is a manually created url like
www.host.com/jetspeed/fileserver/export?portlet=portletwar::portletname&
blablabla
This will call the correct portlet. The problem is that the
PortletRequest object has no parameters set. Neither is there a way to
specify that the processAction() should be called instead of the
render() method.
The file server pipeline is a render pipeline, its not meant for
actions, its meant for "serving files"
To get the portlet request to set parameters from the servlet request,
turn on the non-standard option in your override.properties:
merge.portal.parameters.with.portlet.parameters=true
