Struts Portlet Framework:
This is the initial version of a small framework to allow Struts to be used as
Action handler and context renderer within a portlet.
It's far from complete yet but already the standard MailReader example application
does run nicely under Jetspeed 2.
This example application can be found under the demo folder.
Documentation I haven't really written yet (you're looking at all there is right
now) but will be provided as soon as possible.
Overview:
The problem with embedding Struts within a portlet is that Struts processes action
handling and view rendering all in one event.
To be able to use Struts the framework creates a *virtual* servlet context in
which it intercepts the Struts processing after
its action handling and postpones the view rendering to the portlet RenderRequest.
To be able to do this *right* a Struts portlet application needs to follow some
rules.
Not every Struts application will run out of the box!
A Struts page url within the portlet is encoded as a portlet render parameter. To
be able to target a different page, adapted versions
of the <html:form> and <html:link> tags are supplied (taglib struts-portlet.tld).
These will generated a PortletURL with the target
page correctly encoded as (action) parameter. Other Struts tags will have to be
adapted as well but only these are done for now.
Assumptions, restrictions and features:
All user interactions go through actions. Direct jsp access by the user will break
the framework. This is already *recommended*
for any Struts application so this should be not a big problem. Enforce this by
storing all jsp files beneath WEB-INF.
Struts page url's may not contain '|' or '$' characters. These are currently used
to encode a page url to be able to use it as
a render parameter.
No direct output rendering from an action. All output should be rendered from an
ActionForward after action processing.
After an action the resulting view rendering ActionForward is included, forwarded
or redirected to by Struts. The framework will
intercept this and postpone the actual rendering to the RenderRequest event of the
portlet.
For an include or forward the current Struts context will be temporarily saved in
a StrutsRenderContext object in the session. This
contains the actual render path, the current ActionMapping, ActionForm,
ActionMessages and errors (if defined).
For a redirect just the new Struts page url will be set (note: these
ActionForwards need to point at an action mapping, NOT a jsp).
During a RenderRequest the framework will send Struts once again through the same
processing path but will intercept before it will
actually start checking/validating parameters. It'll then check if a
StrutsRenderContext is available. If so, the context will be
loaded into the request context and the saved ActionForward path will now be
included (forwards are not allowed in portlets). Otherwise
Struts will just continue processing (but won't have any parameters to process).
The consequence of this solution is that input action chaining isn't supported
(atleat not yet). So action processing realy should be
done in one action only. Furthermore, view rendering should normally NOT be
dependent on request scope input parameters. This is
supported by the StrutsRenderContext (which ONLY saves the ActionForm and messages
and currently NO other parameters or attributes)
but really only meant for handling validation errors and will only work once
(refreshing after a validation error will clear any input
/errormessage). A proper MVC implementation should already give you that by the
way. If input state has to be preserved beyond one
request, session scope ActionForms and ActionMessages stored in the session
(supported since Struts 1.2) should be used.
To get the proper flow, ActionForwards used after a successfull action processing
really should define redirect="true".
Struts will normaly forward back to the error page after a validation error. The
input attribute of the actionmapping is used for that.
But this normally is pointing to a ActionForward directed at an jsp or pointing to
a jsp itself. That won't do using this framework.
Therefore the page url requesting the action is saved by the struts-portlet tags
as well. If after an action processing errors are
found the framework will ignore the input page url but uses its own saved url.
One thing which the framework supports will formally this is not allowed in a
portlet is accepting response.sendError() calls. During
ActionRequest processing the error code (and optional message) are saved in a
StrutsErrorContext. When the RenderRequest comes along
an error page will be rendered (currently embedded within StrutsPortlet). A page
refresh will bring up the current Struts page again.
Futhermore, any non-handled exception will end up on that *catch-all* error page.
Usage:
- run maven install (default goal so just maven will do)
This will build and install (in your local maven repository) two jars:
- struts-portlet-spi-<version>.jar
- struts-portlet-<version>.jar
The spi jar only contains the StrutsServletContextProvider interface.
This interface has to be implemented for a specific portal and gives the
struts-portlet access to the servlet context
its running in. For J2 this has already been done:
org.apache.jetspeed.portlet.StrutsServletContextProviderImpl and
globabally available to any J2 portlet (embedded in the
jetspeed-commons-<version>.jar located in Tomcat/shared/lib).
The J2 implementation with J2 running under Tomcat 4.1.29 is the only one which
has been tested so far.
The other jar contains the framework classes. This jar has to be put in the
WEB-INF/lib of a portlet.
- create/modify web.xml:
Define as action servlet: org.apache.struts.portlet.PortletServlet which extends
org.apache.struts.action.ActionServlet.
Define an extension mapping for the action servlet (*.do). Directory mapping is
not supported.
Add the struts-portlet.tld taglib. The .tld can be found in folder tld.
- create/modify portlet.xml:
Use as portlet-class: org.apache.struts.portlet.StrutsPortlet
Define the following init-param elements:
- name: ServletContextProvider
value: org.apache.jetspeed.portlet.StrutsServletContextProviderImpl (or
one of your own if not using J2)
required: yes
- name: ViewPage
value: <action mapping> to welcome page like: /welcome.do or /index.do
(note the extension: jsp's won't do)
required: yes
The welcome file list from web.xml is not used!
- name: EditPage
value: <action mapping> to default edit page
required: no, default taken from ViewPage
- name: HelpPage
value: <action mapping> to default help page
required: no, default taken from ViewPage
- name: ActionPage
value: <action mapping> to default action page
required: no, default taken from ViewPage
- Use the right struts.jar and its .tld files. The framework is developed against
the nightly build of 20040407. Anything
after that will probably/hopefully work.
- Copy the struts-portlet.tld from this project to your tld folder.
- modify struts-config.xml:
Define as controller processorClass:
org.apache.struts.portlet.PortletRequestProcessor.
Note, tiles usage isn't possible yet (probably won't be difficult to support so
maybe soon).
- replace all struts tags which generate action urls:
The struts-portlet.tld currently contains adaptions for <html:form> and
<html:link>. Others will need to be provided later.
These adapted tags ensures the correct portlet url's will be generated.
- replace remote javascript retrieval ( <javascript src="url"/> with
<struts-portlet:script src="url"/> for the same reason
as above.
- setup the actions and mappings with respect to the above mentioned assumptions
and restrictions.
Demo:
As example implementation and proof of concept the Struts MailReader example
application (from nightly build 20040407) is
is converted to a Struts portlet.
The example has been modified on the following points:
- all jsp files and the tour.html are moved below WEB-INF in folder view.
- the <html:form> and <html:link> tags are replaced by their struts-portlet
versions
- the remote javascript tags (for validation) are replaced by the struts-portlet
script tag
- the welcome file index.jsp is removed (not needed anymore and did issue an
illegal forward anyway)
- the CheckLogonTag has been removed:
This one issued an illegal forward when the user wasn't logged on. Besided being
*bad* practice to do flow control during
view rendering having moved the jsp files below the WEB-INF now enforced action
processing anyway so the check is done now
appropriately there.
- The struts-config files (there are two) are modified according the above rules.
- Logoff doesn't invalidate the session anymore which could interfere with the
current session implementation in J2 (which
as far as I know is shared between all portlets, not sure if that's according to
the specs though).
Known issues:
- JS2-11 (http://nagoya.apache.org/jira/browse/JS2-11) currently requires
web-app_2_3.dtd to be available from the working
directory when deploying the demo application. [FIXED 2004-04-19 DST]
- JS2-14 (http://nagoya.apache.org/jira/browse/JS2-14) breaks the local anchor
references in the tour. [FIXED 2004-04-19 DST]
To build and deploy navigate to the demo folder and run (make sure the production
database is running):
maven deploy
Note that the project.properties in the demo folder should be adapted to your
environment first!
Undeploy using:
maven undeploy
During deployment/undeployment an example portlet-entity is inserted/removed from
the database using ID 15 (the next one
available if just the jetspeed demo portlets are all deployed).
Under subfolder jetspeed an example struts-demo.psml and an extended
Log4J.properties file can be found for testing the
example under jetspeed. Simply copy these files over to your deployed jetspeed
webapp folder.
As the demo is configured for deployment under Jetspeed-2 a Struts Portlet SPI
implementation will be available at runtime.
To get it running under a different portal an implementation for
StrutsServletContextProvider has to be provided. If its not
delivered by the portal itself you can try to define one yourself and include it
in the demo together with the spi jar.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
