</div><p>You may have an existing JSP (or Struts, Spring MVC, etc.)
application that you want to migrate to Tapestry. It's quite common to do this
in stages, moving some functionality into Tapestry and leaving other parts,
initially, in the other system. <a href="request-processing-faq.html">You may
need to prevent Tapestry from handling certain requests</a>.</p><h2
id="Integrationwithexistingapplications-HowdoImakeaformonaJSPsubmitintoTapestry?">How
do I make a form on a JSP submit into Tapestry?</h2><p>Tapestry's Form
component does a lot of work while an HTML form is rendering to store all the
information needed to handle the form submission in a later request; this is
all very specific to Tapestry and the particular construction of your pages and
forms; it can't be reproduced from a JSP.</p><p>Fortunately, that isn't
necessary: you can have a standard HTML Form submit to a Tapestry page, you
just don't get to use all of Tapestry's built in conversion and validation
logic.</p><p>
All you need to know is how Tapestry converts page class names to page names
(that appear in the URL). It's basically a matter of stripping off the
<em>root-package</em>.<code>pages</code> prefix from the fully qualified class
name. So, for example, if you are building a login screen as a JSP, you might
want to have a Tapestry page to receive the user name and password. Let's
assume the Tapestry page class is
<code>com.example.myapp.pages.LoginForm</code>; the page name will be
<code>loginform (although, since </code><span>Tapestry is case
insensitive, LoginForm would work just as well)</span><span>, and the URL will
be </span><code>/loginform</code><span>.</span></p><div class="code panel pdl"

means your browser has not been able to load the tapestry.js file properly. The
question is, why? It can be due to multiple reasons, some of them
below:</p><ul><li>First, check if 'tapestry.js' is present in the head part of
your resulting HTML page.</li><li><p>If you have set the <a
href="configuration.html">tapestry.combine-scripts</a> configuration symbol to
true, Tapestry generates one single URL to retrieve all the JS files.
Sometimes, this can produce long URLs that browsers are unable to retrieve. Try
setting the symbol to false.</p><div class="confluence-information-macro

class="confluenc
e-information-macro-body"><p>This only applies to Tapestry
5.1.</p></div></div></li><li>If you have included jQuery in conjunction with
Tapestry's prototype, that will cause a conflict with the '$' selector used by
both. In this case, you should put jQuery on top of the stack and turn on the
<a class="external-link" href="http://api.jquery.com/jQuery.noConflict/";
rel="nofollow">jQuery.noConflict</a> mode.</li><li>Also, if you have included a
custom or third-party JS library on top of the stack that causes the JavaScript
parsing to fail, then check the JavaScript syntax in that library.</li><li>If
you have used a tool to minimize your JavaScript libraries, this can lead to
JavaScript syntax errors, so check if it works with all the JavaScript files
unpacked.</li></ul><h2
id="JavaScriptFAQ-What'sthedifferencebetweentheT5objectandtheTapestryobjectinthebrowser?(5.3andearlier)">What's
the difference between the <code>T5</code> object and the
<code>Tapestry</code> object in the browser? (
5.3 and earlier)</h2><p>Both of these objects are <em>namespaces</em>:
containers of functions, constants, and nested namespaces.</p><p>The
<code>T5</code> object is a replacement for the <code>Tapestry</code> object,
starting in release 5.3. Increasingly, functions defined by the
<code>Tapestry</code> object are being replaced with similar or equivalent
functions in the <code>T5</code> object.</p><p>This is part of an overall goal,
spanning at least two releases of Tapestry, to make Tapestry JavaScript
framework agnostic; which is to say, not depend specifically on Prototype or
jQuery. Much of the code in the <code>Tapestry</code> object is specifically
linked to Prototype and Scriptaculous.</p><p>The <code>T5</code> object
represents a stable, documented, set of APIs that are preferred when building
components for maximum portability between underlying JavaScript frameworks. In
other words, when building component libraries, coding to the <code>T5</code>
object ensures that your c
omponent will be useful regardless of whether the final application is built
using Prototype, jQuery or something else.</p></div>

id="Limitations-HowdoIaddnewcomponentstoanexistingpagedynamically?">How do I
add new components to an existing page dynamically?</h2><p>The short answer
here is: <strong>you don't</strong>. The long answer here is <strong>you don't
have to, to get the behavior you desire</strong>.</p><p>One of Tapestry basic
values is high scalability: this is expressed in a number of ways, reflecting
scalability concerns within a single server, and within a cluster of
servers.</p><p>Although you code Tapestry pages and components as if they were
ordinary POJOs (<span>Plain Old Java Objects -- Tapestry does not require you
to extend any base classes or implement any special interfaces)</span><span>,
as deployed by Tapestry they are closer to a traditional servlet: a single
instance of each page services requests from multiple threads. Behind the
scenes, Tapestry transforms you code, rewriting it on the
fly.</span></p><p>What this means is that <em>any</em> incoming request must be
handled
by a <em>single page instance</em>. Therefore, Tapestry enforces the concept
of <strong>static structure, dynamic behavior</strong>.</p><p>Tapestry provides
quite a number of ways to vary what content is rendered, well beyond simple
conditionals and loops. It is possible to "drag in" components from other pages
when rendering a page (other FAQs will expand on this concept). The point is,
that although a Tapestry page's structure is very rigid, the order in which the
components of the page render does not have to be top to bottom.</p><h2

doesn't my service implementation reload when I change it?</h2><p>Main article:
<a href="service-implementation-reloading.html">Service Implementation

service must define a service interface.</li><li>The service implementation
must be on the file system (not inside a JAR).</li><li>The implementatio

do Maven project names and other details show up in my pages?</h2><p>Tapestry
and maven both use the same syntax for dynamic portions of files: the
<code>${...</code>} syntax. When Maven is copying resources from
<code>src/main/resources</code>, and when filtering is <em>enabled</em> (which
is not the default), then any expansions in <em>Tapestry templates</em> that
match against Maven project properties are substituted. If you look at the
deployed application you'll see that <code>${name</code>} is gone, replaced
with your project's name!</p><p>The solution is to update your
<code>pom.xml</code> and ignore any .tml files when copying and
filtering:</p><div class="code panel pdl" style="border-width: 1px;"><div

id="PageAndComponentClassesFAQ-What'sthedifferencebetweenapageandacomponent?">What's
the difference between a page and a component?</h2><p>There's very little
difference between the two. Pages classes must be in the
<em>root-package</em>.<code>pages</code> package; components must be in the
<em>root-package</em>.<code>components</code>. Pages may provide event handlers
for certain page-specific events (such as activate and passivate). Components
may have parameters.</p><p>Other than that, they are more equal than they are
different. They may have templates or may render themselves in code (pages
usually have a template, components are more likely to render only in
code).</p><p>The major difference is that Tapestry page templates may be stored
in the web context directory, as if they were static files (they can't be
accessed from the client however; a specific rule prevents access to files with
the <code>.tml</code> extension).</p><div class="confluence-information-macro co

id="PageAndComponentClassesFAQ-HowdoIstoremypageclassesinadifferentpackage?">How
do I store my page classes in a different package?</h2><p>Tapestry is very
rigid here; you can't. Page classes must go in
<em>root-package</em>.<code>pages</code>, component classes in
<em>root-package</em>.<code>components</code>, etc.</p><p>You are allowed to
create sub-packages, to help organize your code better and more logically. For
example, you might have
<em>root-package</em>.<code>pages.account.ViewAccount</code>, which would have
the page name "account/viewaccount". (<span>Tapestry would also create an alias
"account/view", by stripping of
f the redundant "account" suffix. Either name is equally valid in your code,
and Tapestry will use the shorter name, "account/view" in
URLs.)</span></p><p>In addition, it is possible to define additional root
packages for the application:</p><div class="code panel pdl"

</p><p>In a Tapestry application, most application classes are loaded from the
middle class loader. Additional class loaders are used to support live service
reloading, and live component reloading (along with component class
transformation).</p><p>When a page or component is passed as a parameter to a
service, a failure occurs (how it is reported varies in different JDK releases)
because of the class mismatch.</p><p>The solution is to define an interface
with the methods that the service will invoke on the page or component
instance. The service will expect an object implementing the interface (and
doesn't care what class loader loaded the implementing class).</p><p>Just be
sure to put the interface class in a non-controlled package, such as your
application's <em>root-package</em> (and <strong>not</strong>
<em>root-package</em>.<code>pages</code>).</p><h2
id="PageAndComponentClassesFAQ-Whichisbetter,usingmagicmethodnames(i.e.,beginRender())orannotations(i.e.BeginRender)?">Which
is
better, using magic method names (i.e., <code>beginRender()</code>) or
annotations (i.e. <code>BeginRender</code>)?</h2><p>There is no single best
way; this is where your taste may vary. Historically, the annotations came
first, and the method naming conventions came later.</p><p>The advantage of
using the method naming conventions is that the method names are more concise,
which fewer characters to type, and fewer classes to import.</p><p>The main
disadvantage of the method naming conventions is that the method names are not
meaningful. <code>onSuccessFromLoginForm()</code> is a less meaningful name
than <code>storeUserCredentialsAndReturnToProductsPage()</code>, for
example.</p><p>The second disadvantage is you are more susceptible to
off-by-a-character errors. For example, <code>onSucessFromLoginForm()</code>
will <em>never</em> be called because the event name is misspelled; this would
not happen using the annotation approach:</p><div class="code panel pdl"

<p>In essence, a Tapestry application is a number of related pages, working
together. To some degree, each page is like an application unto
itself.</p><p>Any individual request will be targeted at a single page.
Requests come in two forms: </p><ul><li><em>component event</em> requests
target a specific component on a specific page, triggering an event within that
component</li><li><em>render</em> requests target a specific page, and stream
the HTML markup for that page back to the client</li></ul><p>This dichotomy
