These symbols can be overridden by contributing to the ApplicationDefaults service configuration, or by placing a <context-param> element into the application's web.xml, or on the command line by defining JVM System Properties with the -D command line option.</p><p>These symbols are always defined in terms of strings, and those strings are coerced to the appropriate type (a number, a boolean, etc.). Of special note are <em>time intervals</em>, which are specified in a <a class="external-link" href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/ioc/util/TimeInterval.html">particular format</a>.</p><p>Most of these symbols have a constant defined in the <a class="external-link" href="http://tapestry.apache.org/cu

Those are noted in parentheses below. Use the symbol name (tapestry.*) for JVM System Properties with the -D option, and use the constant (in parentheses) from within your Java classes (e.g. AppModule.java).</p><h3 id="Configuration-tapestry.app-catalog(SymbolConstants.APPLICATION_CATALOG)">tapestry.app-catalog (SymbolConstants.APPLICATION_CATALOG)</h3><p>The location of the global application message catalog, the default is context:WEB-INF/<em>app-name</em>.properties.</p><h3 id="Configuration-tapestry.application-version(SymbolConstants.APPLICATION_VERSION)">tapestry.application-version (SymbolConstants.APPLICATION_VERSION)</h3><p>The version of the application, which is incorporated into URLs for context and classpath assets.

You should change the application version on each new deployment of the application (that is, any time assets in the context change), to force clients to re-download changed versions of files. If you do not specify an application version, a <em>random</em> one will be assigned on every deployment (which is good for development but very bad for production).</p><h3 id="Configuration-tapestry.application-folder(SymbolConstants.APPLICATION_FOLDER)">tapestry.application-folder (SymbolConstants.APPLICATION_FOLDER)</h3>

<p> </p><p>Tapestry provides support for creating and rendering forms, populating their fields, and validating user input. For simple cases, input validation is declarative, meaning you simply tell Tapestry what validations to apply to a given field, and it takes care of it on the server and (optionally) on the client as well. In addition, you can provide event handler methods in your page or component classes to handle more complex validation scenarios.</p><p>Finally, Tapestry not only makes it easy to present errors messages to the user, but it can also automatically highlight form fields when validation fails.</p><p><strong>Contents</strong></p><p><style type="text/css">/*<![CDATA[*/
