pipeline is very important, as it is one of the chief extension points for
Tapestry.</p><p>Much of the early stages of processing are in the form of
extensible <a shape="rect"
href="pipelinebuilder-service.html">pipelines</a>.</p><h2
id="RequestProcessing-TapestryFilter">Tapestry Filter</h2><p>All incoming
requests originate with the TapestryFilter, which is configured inside the
application's <a shape="rect" href="configuration.html">web.xml</a>.</p><p>The
TapestryFilter is responsible for a number of startup and initialization
functions.</p><p>When it receives a request, the TapestryFilter obtains the <a
shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/HttpServletRequestHandler.html";>Htt
pServletRequestHandler</a> service, and invokes its service() method.</p><h2
id="RequestProcessing-HttpServletRequestHandlerPipeline">HttpServletRequestHandler
Pipeline</h2><p>This pipeline performs initial processing of the request. It
can be extended by contributing a <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/HttpServletRequestFilter.html";>HttpServletRequestFilter</a>
into the HttpServletRequestHandler service's configuration.</p><p>Tapestry
does not contribute any filters into this pipeline of its own.</p><p>The
terminator for the pipeline does two things:</p><ul><li>It stores the request
and response into the <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/RequestGlobals.html";>RequestGlobals</a>
service. This is a per-thread scoped service that stores
per-thread/per-request information.</li><li>It wraps the request and response
as a <a s
hape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/Request.html";>Request</a>
and <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/Response.html";>Response</a>,
and passes them into the <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/RequestHandler.html";>RequestHandler</a>
pipeline.</li></ul><h2
id="RequestProcessing-RequestHandlerPipeline">RequestHandler
Pipeline</h2><p>This pipeline is where most extensions related to requests take
place. Request represents an abstraction on top of HttpServletRequest.
(Primarily, this exists to bridge from the Servlet API objects to the
corresponding Tapestry objects. This is the basis for the planned portlet
integration for Tapestry.) Where other code and services within Tapestry
require access to information in the request, such as query parameters, th
at information is obtained from the Request (or Response) objects.</p><p>The
RequestHandler pipeline includes a number of built-in
filters:</p><ul><li>CheckForUpdates is responsible for <a shape="rect"
href="class-reloading.html">class and template
reloading</a>.</li><li>Localization identifies the <a shape="rect"
href="localization.html">locale for the user</a>.</li><li>StaticFiles checks
for URLs that are for static files (files that exist inside the web context)
and aborts the request, so that the servlet container can handle the request
normally.</li><li>ErrorFilter catches uncaught exceptions from the lower levels
of Tapestry and presents the exception report page. This involves the <a
shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/RequestExceptionHandler.html";>RequestExceptionHandler</a>
service, which is responsible for initializing and rendering the <a
shape="rect" class="external-link" href="http://tapestry.
apache.org/current/apidocs/org/apache/tapestry5/corelib/pages/ExceptionReport.html">core/ExceptionReport</a>
page.</li></ul><p>The terminator for this pipeline stores the Request and the
Response into RequestGlobals, then requests that the <a shape="rect"
class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/Dispatcher.html";>MasterDispatcher</a>
service figure out how to handle the request (if it is, indeed, a Tapestry
request).</p><h2 id="RequestProcessing-MasterDispatcherService">Master
Dispatcher Service</h2><p>The MasterDispatcher service is a chain-of-command,
aggregating together (in a specific order), several Dispatcher objects. Each
Dispatcher is built to recognize and process a particular kind of URL.</p><h3
id="RequestProcessing-RootPathDispatcher">RootPath Dispatcher</h3><p>The
RootPath Dispatcher recognizes a request for the application root (i.e., "/")
and handles this the same as a render request for the "Start" page. Supp
ort for the Start page is kept for legacy purposes. Index pages are the
correct approach.</p><h3 id="RequestProcessing-AssetDispatcher">Asset
Dispatcher</h3><p>Requests that begin with "/assets/" are references to <a
shape="rect" href="assets.html">asset resources</a> that are stored on the
classpath, inside the Tapestry JARs (or perhaps inside the JAR for a component
library). The contents of the file will be delivered to the client browser as a
byte stream. This dispatcher also handles requests that are simply polling for
a change to the file.</p><h3
id="RequestProcessing-PageRenderDispatcher">PageRender Dispatcher</h3><p>Page
render requests are requests to render a particular page. Such requests may
include additional elements on the path, which will be treated as activation
context (see ComponentEvent Dispatcher below). Generally speaking, the
activation context is the primary key of some related entity object. This
allows the page to reconstruct the state it will need to succe
ssfully render itself.</p><p>The event handler method for the activate event
may return a value; this is treated the same as the return value from a
component action request; typically this will result in a redirect to another
page. In this way, the activate event can perform simple validation at the page
level ("can the user see this page?").</p><p>Page render URLs consist of the
logical name of the page plus additional path elements for the activation
context. The dispatcher here strips terms off of the path until it finds a
known page name. Thus, "/mypage/27" would look first for a page whose name was
"mypage/27", then look for a page name "mypage". Assuming the second search was
successful, the page would be activated with the context "27". If no logical
page name can be identified, control passes to the next dispatcher.</p><h3
id="RequestProcessing-ComponentEventDispatcher">ComponentEvent
Dispatcher</h3><p>The ComponentEvent dispatcher is used to trigger events in
components.</
p><p>The URL identifies the name of the page, then a series of component ids
(the path from the page down to the specific component), then the name of the
event to be triggered on the component. The remaining path elements are used as
the context for the <em>event</em> (not for the page activation, which does not
currently apply). For example, "/griddemo.FOO.BAR/3" would locate page
"griddemo", then component "FOO.BAR", and trigger an event named "action" (the
default event type, which is omitted from the URL), with the context
"3".</p><p>If the page in question has an activation context, it is supplied as
an additional query parameter on the link.</p><p>In cases where the event type
is not the default, "action", it will appear between the nested component id
and the event context, preceded by a colon. Example:
"/example/foo.bar:magic/99" would trigger an event of type "magic". This is not
common in the vanilla Tapestry framework, but will likely be more common as
Ajax features (whi
ch would not use the normal request logic) are implemented.</p><p>The response
from a component action request is typically, but not universally, used to send
a redirect to the client; the redirect URL is a page render URL to display the
response to the event. This is detailed under <a shape="rect"
href="page-navigation.html">Page Navigation</a>.</p><h2
id="RequestProcessing-RequestGlobalsService">RequestGlobals Service</h2><p>The
RequestGlobals service has a life cycle of per-thread; this means that a
separate instance exists for every thread, and therefore, for every request.
The terminators of the two handler pipelines store the request/response pairs
into the RequestGlobals service.</p><h2
id="RequestProcessing-RequestService">Request Service</h2><p>The Request
service is a <a shape="rect" href="shadowbuilder-service.html">shadow</a> of
the RequestGlobals services' request property. That is, any methods invoked on
this service are delegated to the request object stored inside th
e RequestGlobals.</p><h2 id="RequestProcessing-Overview">Overview</h2><p>The
following diagram provides an overview of how the different pipelines, filters
and dispatchers interact when processing an incoming request.</p><p><span

Tapestry performs when every HTTP request comes in. You <em>don't need</em> to
know these steps to use Tapestry productively, but understanding the request
processing pipeline is helpful if you want to understand Tapestry
deeply.</p><p>Much of the early stages of processing are in the form of
extensible <a shape="rect"
href="pipelinebuilder-service.html">pipelines</a>.</p><h2
id="RequestProcessing-TapestryFilter">Tapestry Filter</h2><p>All incoming
requests originate with the TapestryFilter, which is a servlet filter
configured inside your application's <a shape="rect"
href="configuration.html">web.xml</a>.</p><p>The TapestryFilter is responsible
for a number of startup and initialization functions.</p><p>When it receives a
request, the TapestryFilter obtains the <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/HttpServletRequestHandler.h
tml">HttpServletRequestHandler</a> service, and invokes its service()
method.</p><h2
id="RequestProcessing-HttpServletRequestHandlerPipeline">HttpServletRequestHandler
Pipeline</h2><p>This pipeline performs initial processing of the request. It
can be extended by contributing a <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/HttpServletRequestFilter.html";>HttpServletRequestFilter</a>
into the HttpServletRequestHandler service's configuration.</p><p>Tapestry
does not contribute any filters into this pipeline of its own.</p><p>The
terminator for the pipeline does two things:</p><ul><li>It stores the request
and response into the <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/RequestGlobals.html";>RequestGlobals</a>
service. This is a per-thread scoped service that stores
per-thread/per-request information.</li><li>It wraps the request and response a
s a <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/Request.html";>Request</a>
and <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/Response.html";>Response</a>,
and passes them into the <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/RequestHandler.html";>RequestHandler</a>
pipeline.</li></ul><h2
id="RequestProcessing-RequestHandlerPipeline">RequestHandler
Pipeline</h2><p>This pipeline is where most extensions related to requests take
place. Request represents an abstraction on top of HttpServletRequest.
(Primarily, this exists to bridge from the Servlet API objects to the
corresponding Tapestry objects. This is the basis for the planned portlet
integration for Tapestry.) Where other code and services within Tapestry
require access to information in the request, such as query parame
ters, that information is obtained from the Request (or Response)
objects.</p><p>The RequestHandler pipeline includes a number of built-in
filters:</p><ul><li>CheckForUpdates is responsible for <a shape="rect"
href="class-reloading.html">class and template
reloading</a>.</li><li>Localization identifies the <a shape="rect"
href="localization.html">locale for the user</a>.</li><li>StaticFiles checks
for URLs that are for static files (files that exist inside the web context)
and aborts the request, so that the servlet container can handle the request
normally.</li><li>ErrorFilter catches uncaught exceptions from the lower levels
of Tapestry and presents the exception report page. This involves the <a
shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/RequestExceptionHandler.html";>RequestExceptionHandler</a>
service, which is responsible for initializing and rendering the <a
shape="rect" class="external-link" href="http://t
apestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/pages/ExceptionReport.html">core/ExceptionReport</a>
page.</li></ul><p>The terminator for this pipeline stores the Request and the
Response into RequestGlobals, then requests that the <a shape="rect"
class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/Dispatcher.html";>MasterDispatcher</a>
service figure out how to handle the request (if it is, indeed, a Tapestry
request).</p><h2 id="RequestProcessing-MasterDispatcherService">Master
Dispatcher Service</h2><p>The MasterDispatcher service is a chain-of-command,
aggregating together (in a specific order), several Dispatcher objects. Each
Dispatcher is built to recognize and process a particular kind of URL.</p><h3
id="RequestProcessing-RootPathDispatcher">RootPath Dispatcher</h3><p>The
RootPath Dispatcher recognizes a request for the application root (i.e., "/")
and handles this the same as a render request for the "Start" pa
ge. Support for the Start page is kept for legacy purposes. Index pages are
the correct approach.</p><h3 id="RequestProcessing-AssetDispatcher">Asset
Dispatcher</h3><p>Requests that begin with "/assets/" are references to <a
shape="rect" href="assets.html">asset resources</a> that are stored on the
classpath, inside the Tapestry JARs (or perhaps inside the JAR for a component
library). The contents of the file will be delivered to the client browser as a
byte stream. This dispatcher also handles requests that are simply polling for
a change to the file.</p><h3
id="RequestProcessing-PageRenderDispatcher">PageRender Dispatcher</h3><p>Page
render requests are requests to render a particular page. Such requests may
include additional elements on the path, which will be treated as activation
context (see ComponentEvent Dispatcher below). Generally speaking, the
activation context is the primary key of some related entity object. This
allows the page to reconstruct the state it will need
to successfully render itself.</p><p>The event handler method for the activate
event may return a value; this is treated the same as the return value from a
component action request; typically this will result in a redirect to another
page. In this way, the activate event can perform simple validation at the page
level ("can the user see this page?").</p><p>Page render URLs consist of the
logical name of the page plus additional path elements for the activation
context. The dispatcher here strips terms off of the path until it finds a
known page name. Thus, "/mypage/27" would look first for a page whose name was
"mypage/27", then look for a page name "mypage". Assuming the second search was
successful, the page would be activated with the context "27". If no logical
page name can be identified, control passes to the next dispatcher.</p><h3
id="RequestProcessing-ComponentEventDispatcher">ComponentEvent
Dispatcher</h3><p>The ComponentEvent dispatcher is used to trigger events in
compo
nents.</p><p>The URL identifies the name of the page, then a series of
component ids (the path from the page down to the specific component), then the
name of the event to be triggered on the component. The remaining path elements
are used as the context for the <em>event</em> (not for the page activation,
which does not currently apply). For example, "/griddemo.FOO.BAR/3" would
locate page "griddemo", then component "FOO.BAR", and trigger an event named
"action" (the default event type, which is omitted from the URL), with the
context "3".</p><p>If the page in question has an activation context, it is
supplied as an additional query parameter on the link.</p><p>In cases where the
event type is not the default, "action", it will appear between the nested
component id and the event context, preceded by a colon. Example:
"/example/foo.bar:magic/99" would trigger an event of type "magic". This is not
common in the vanilla Tapestry framework, but will likely be more common as
Ajax featu
res (which would not use the normal request logic) are implemented.</p><p>The
response from a component action request is typically, but not universally,
used to send a redirect to the client; the redirect URL is a page render URL to
display the response to the event. This is detailed under <a shape="rect"
href="page-navigation.html">Page Navigation</a>.</p><h2
id="RequestProcessing-RequestGlobalsService">RequestGlobals Service</h2><p>The
RequestGlobals service has a life cycle of per-thread; this means that a
separate instance exists for every thread, and therefore, for every request.
The terminators of the two handler pipelines store the request/response pairs
into the RequestGlobals service.</p><h2
id="RequestProcessing-RequestService">Request Service</h2><p>The Request
service is a <a shape="rect" href="shadowbuilder-service.html">shadow</a> of
the RequestGlobals services' request property. That is, any methods invoked on
this service are delegated to the request object stored i
nside the RequestGlobals.</p><h2
id="RequestProcessing-Overview">Overview</h2><p>The following diagram provides
an overview of how the different pipelines, filters and dispatchers interact
when processing an incoming request.</p><p><span
