| implements javax.servlet.Filter</pre> |
| <div class="block">A filter that creates a Cayenne server runtime, possibly including custom modules. By |
| default runtime includes <a href="../../../../../org/apache/cayenne/configuration/server/ServerModule.html" title="class in org.apache.cayenne.configuration.server"><code>ServerModule</code></a> and <a href="../../../../../org/apache/cayenne/configuration/web/WebModule.html" title="class in org.apache.cayenne.configuration.web"><code>WebModule</code></a>. Any custom modules |
| are loaded after the two standard ones to allow custom service overrides. Filter |
| initialization parameters: |
| <ul> |
| <li>configuration-location - (optional) a name of Cayenne configuration XML file that |
| will be used to load Cayenne stack. If missing, the filter name will be used to derive |
| the location. ".xml" extension will be appended to the filter name to get the location, |
| so a filter named "cayenne-foo" will result in location "cayenne-foo.xml". |
| <li>extra-modules - (optional) a comma or space-separated list of class names, with |
| each class implementing <a href="../../../../../org/apache/cayenne/di/Module.html" title="interface in org.apache.cayenne.di"><code>Module</code></a> interface. These are the custom modules loaded |
| after the two standard ones that allow users to override any Cayenne runtime aspects, |
| e.g. <a href="../../../../../org/apache/cayenne/configuration/web/RequestHandler.html" title="interface in org.apache.cayenne.configuration.web"><code>RequestHandler</code></a>. Each custom module must have a no-arg constructor. |
| </ul> |
| <p> |
| CayenneFilter is a great utility to quickly start a Cayenne application. More advanced |
| apps most likely will not use it, relying on their own configuration mechanism (such as |
| Guice, Spring, etc.)</div> |
