Thanks a lot, Richard, that was REALLY instructive :D
And here is the configuration that I managed to get working:
<construct class="com.test.util.SecurityBeanFactory">
<set-object property="request"
value="service:tapestry.globals.HttpServletRequest" />
</construct>
Cheers,
Alexander

Hi Alexander,
There are loads of docs! The thing to know is that the <construct> part
is a general feature of HiveMind1, so look at the docs at
http://hivemind.apache.org/, however within a Tapestry project you
naturally want to access Tapestry related services, so look at
http://tapestry.apache.org/ for info there.
For your specific question of obtaining the HttpServletRequest, you need
to locate where that is offered. The route I followed is:
tapestry.apache.org
Select the tapestry4 version from left hand menu.
Select Framework from left hand menu.
Select Reports from the dropped down menu.
Select HiveDoc.
Search for HttpServletRequest to get the answer that
tapestry.globals.HttpServletRequest is a service.
Therefore to add this service to your SecurityBeanFactory, just add the
line:
<set-service property="httpServletRequest"
service-id="service:HttpServletRequest" />
inside your <construct>
and provide a:
public void setHttpServletRequest(javax.servlet.http.HttpServletRequest
request) {
this.request = request;
}
method in your SecurityBeanFactory class.
Note from the HiveDoc description that the
tapestry.globals.HttpServletRequest is a threaded service, which means
that it magically returns the actual HttpServletRequest object for that
particular web request (cheers to Howard for such a brilliant
implementation!).
Cheers
Richard
