</PRE>
<P>
Provides a <a target="_blank" href="http://velocity.apache.org//">Velocity</a> TemplateService class.
<p/>
Velocity provides a simple to use, but powerful and performant templating engine
for the Click Framework. The Velocity templating engine is configured and accessed
by this VelocityTemplateService class.
Velocity is the default templating engine used by Click and the Velocity class
dependencies are included in the standard Click JAR file.
<p/>
You can also instruct Click to use a different template service implementation.
Please see <A HREF="../../../../org/apache/click/service/TemplateService.html" title="interface in org.apache.click.service"><CODE>TemplateService</CODE></A> for more details.
<p/>
To see how to use the Velocity templating language please see the
<a target="blank" href="../../../../../velocity/VelocityUsersGuide.pdf">Velocity Users Guide</a>.
<h3>Velocity Configuration</h3>
The VelocityTemplateService is the default template service used by Click,
so it does not require any specific configuration.
However if you wanted to configure this service specifically in your
<tt>click.xml</tt> configuration file you would add the following XML element.
<pre class="codeConfig">
&lt;<span class="red">template-service</span> classname="<span class="blue">org.apache.click.service.VelocityTemplateService</span>"/&gt; </pre>
<h4>Velocity Properties</h4>
The Velocity runtime engine is configured through a series of properties when the
VelocityTemplateService is initialized. The default Velocity properties set are:
<pre class="codeConfig">
resource.loader=<span class="blue">webapp</span>, <span class="red">class</span>
<span class="blue">webapp</span>.resource.loader.class=org.apache.velocity.tools.view.WebappResourceLoader
<span class="blue">webapp</span>.resource.loader.cache=[true|false] &nbsp; <span class="green">#depending on application mode</span>
<span class="blue">webapp</span>.resource.loader.modificationCheckInterval=0 <span class="green">#depending on application mode</span>
<span class="red">class.resource</span>.loader.class=org.apache.velocity.runtime.loader.ClasspathResourceLoader
<span class="red">class.resource</span>.loader.cache=[true|false] &nbsp; <span class="green">#depending on application mode</span>
<span class="red">class.resource</span>.loader.modificationCheckInterval=0 <span class="green">#depending on application mode</span>
velocimacro.library.autoreload=[true|false] <span class="green">#depending on application mode</span>
velocimacro.library=click/VM_global_library.vm
</pre>
This service uses the Velocity Tools WebappResourceLoader for loading templates.
This avoids issues associate with using the Velocity FileResourceLoader on JEE
application servers.
<p/>
See the Velocity
<a target="topic" href="../../../../../velocity/developer-guide.html#Velocity Configuration Keys and Values">Developer Guide</a>
for details about these properties. Note when the application is in <tt>trace</tt> mode
the Velocity properties used will be logged on startup.
<p/>
If you want to add some of your own Velocity properties, or replace Click's
properties, add a <span class="blue"><tt>velocity.properties</tt></span> file in the <tt>WEB-INF</tt>
directory. Click will automatically pick up this file and load these properties.
<p/>
As a example say we have our own Velocity macro library called
<tt>mycorp.vm</tt> we can override the default <tt>velocimacro.library</tt>
property by adding a <tt>WEB-INF/velocity.properties</tt> file to our web
application. In this file we would then define the property as:
<pre class="codeConfig">
velocimacro.library=<span class="blue">mycorp.vm</span> </pre>
Note do not place Velocity macros under the WEB-INF directory as the Velocity
ResourceManager will not be able to load them.
<p/>
The simplest way to set your own macro file is to add a file named <span class="blue"><tt>macro.vm</tt></span>
under your web application's root directory. At startup Click will first check to see
if this file exists, and if it does it will use it instead of <tt>click/VM_global_library.vm</tt>.
<h3>Application Modes and Caching</h3>
<h4>Production and Profile Mode</h4>
When the Click application is in <tt>production</tt> or <tt>profile</tt> mode Velocity caching
is enabled. With caching enables page templates and macro files are loaded and
parsed once and then are cached for use with later requests. When in
<tt>production</tt> or <tt>profile</tt> mode the following Velocity runtime
properties are set:
<pre class="codeConfig">
webapp.resource.loader.cache=true
webapp.resource.loader.modificationCheckInterval=0
class.resource.loader.cache=true
class.resource.loader.modificationCheckInterval=0
velocimacro.library.autoreload=false </pre>
When running in these modes the <A HREF="../../../../org/apache/click/service/ConsoleLogService.html" title="class in org.apache.click.service"><CODE>ConsoleLogService</CODE></A> will be configured
to use
<h4>Development and Debug Modes</h4>
When the Click application is in <tt>development</tt>, <tt>debug</tt> or <tt>trace</tt>
modes Velocity caching is disabled. When caching is disabled page templates
and macro files are reloaded and parsed when ever they changed. With caching
disabled the following Velocity
runtime properties are set:
<pre class="codeConfig">
webapp.resource.loader.cache=false
class.resource.loader.cache=false
velocimacro.library.autoreload=true </pre>
Disabling caching is useful for application development where you can edit page
templates on a running application server and see the changes immediately.
<p/>
<b>Please Note</b> Velocity caching should be used for production as Velocity
template reloading is much much slower and the process of parsing and
introspecting templates and macros can use a lot of memory.
<h3>Velocity Logging</h3>
Velocity logging is very verbose at the best of times, so this service
keeps the logging level at <tt>ERROR</tt> in all modes except <tt>trace</tt>
mode where the Velocity logging level is set to <tt>WARN</tt>.
<p/>
If you are having issues with some Velocity page templates or macros please
switch the application mode into <tt>trace</tt> so you can see the warning
messages provided.
<p/>
To support the use of Click <tt>LogService</tt> classes inside the Velocity
runtime a <A HREF="../../../../org/apache/click/service/VelocityTemplateService.LogChuteAdapter.html" title="class in org.apache.click.service"><CODE>VelocityTemplateService.LogChuteAdapter</CODE></A> class is provided. This class wraps the
Click LogService with a Velocity <tt>LogChute</tt> so the Velocity runtime can
use it for logging messages to.
<p/>
If you are using LogServices other than <A HREF="../../../../org/apache/click/service/ConsoleLogService.html" title="class in org.apache.click.service"><CODE>ConsoleLogService</CODE></A> you will
probably configure that service to filter out Velocity's verbose <tt>INFO</tt>
level messages.
