    <p>Tapestry-Security is just a thin layer on top of the <a href="http://incubator.apache.org/shiro/spring.html" rel="nofollow noreferrer">Apache Shiro</a> project. It only provides: </p> <ul> <li>a way to configure Shiro via your Tapestry application module</li> <li>a set of Tapestry filters to do the actual security checks for Tapestry pages and actions</li> <li><a href="http://tynamo.org/constant/tapestry-security/apidocs/org/tynamo/shiro/extension/authz/annotations/package-summary.html" rel="nofollow noreferrer">annotations</a> should you like to declare your security declaratively</li> <li><a href="http://tynamo.org/constant/tapestry-security/apidocs/org/tynamo/security/components/package-summary.html" rel="nofollow noreferrer">components</a> to support conditional rendering in your <code>.tml</code> files</li> </ul> <p>Underneath that layer, there is an ordinary instance of Shiro doing all the work, so you can access security (for example via the <a href="http://incubator.apache.org/shiro/static/current/apidocs/org/apache/shiro/SecurityUtils.html" rel="nofollow noreferrer">SecurityUtils</a> class) like you normally would if Tapestry wasn't involved at all.</p> <p><em>Edit based on comment:</em> So while you can use Shiro in any web application you use, Tapestry-Security is really just a wrapper for use with Tapestry. If you, however, have an app that includes Tapestry along with other servlets (such as a web service), you should be able to let Tapestry-Security do the initialization work.</p> <p><em>Concerning Tapestry filters:</em> I'm afraid this isn't documented very well. Tapestry filters work very much like Servlet Filters, but as Tapestry is <a href="http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/TapestryFilter.html" rel="nofollow noreferrer">implemented as a Servlet Filter itself</a>, it has its own filter chain. Filters for Tapestry implement the <a href="http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/services/RequestFilter.html" rel="nofollow noreferrer">RequestFilter</a> interface.</p> <pre><code>public class MyFilter implements RequestFilter { @Override public boolean service(final Request request, final Response response, final RequestHandler handler) throws IOException { ... //your code try { return handler.service(request, response); } finally { ... //your code } } } </code></pre> <p>You can add them to the filter chain by contributing them in your application module:</p> <pre><code>public void contributeRequestHandler( final OrderedConfiguration&lt;RequestFilter&gt; configurations) { configuration.add("MyFilter", new MyFilter()); } </code></pre>

    1. COThank you very much for this. Does that mean that tapestry-security can be used without Tapestry achitecture but I would need to add Tapestry-Security filter in whatever application I use ? or that I should use Shiro in my service layer and then use Tapestry-Security in my web application to initialize it ? I get the point on filter, I guess implementing the RequestFilter interface and adding it to the AppModule class by adding its contribute methods, allow me to extends Tapestry capabilites.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
