Wicket is a Java web application framework that takes simplicity,
separation of concerns and ease of development to a whole new level.
Wicket pages can be mocked up, previewed and later revised using
standard WYSIWYG HTML design tools. Dynamic content processing and
form handling is all handled in Java code using a first-class
component model backed by POJO data beans that can easily be
persisted using your favorite technology.
The newest version!

/**
* Base class for all Wicket applications. To create a Wicket application, you generally should
* not directly subclass this class. Instead, you will want to subclass some subclass of
* Application, like WebApplication, which is appropriate for the protocol and markup type you are
* working with.
*
* Application has the following interesting features / attributes:
*
* - Name - The Application's name, which is the same as its class name.
*
*
- Home Page - The Application's home Page class. Subclasses must override getHomePage()
* to provide this property value.
*
*
- Settings - Application settings are partitioned into sets of related settings using
* interfaces in the org.apache.wicket.settings package. These interfaces are returned by the
* following methods, which should be used to configure framework settings for your application:
* getApplicationSettings(), getDebugSettings(), getExceptionSettings(), getMarkupSettings(),
* getPageSettings(), getRequestCycleSettings(), getSecuritySettings and getSessionSettings(). These
* settings are configured by default through the constructor or internalInit methods. Default the
* application is configured for DEVELOPMENT. You can configure this globally to DEPLOYMENT or
* override specific settings by implementing the init() method.
*
*
- Shared Resources - Resources added to an Application's SharedResources have
* application-wide scope and can be referenced using a logical scope and a name with the
* ResourceReference class. ResourceReferences can then be used by multiple components in the same
* application without additional overhead (beyond the ResourceReference instance held by each
* referee) and will yield a stable URL, permitting efficient browser caching of the resource (even
* if the resource is dynamically generated). Resources shared in this manner may also be localized.
* See {@link org.apache.wicket.request.resource.ResourceReference} for more details.
*
*
- Custom Session Subclasses- In order to install your own {@link Session} subclass you
* must override Application{@link #newSession(Request, Response)}. For subclasses of
* {@link WebApplication} you will want to subclass {@link WebSession}.
*
*

* configuration type is DEVELOPMENT, resources are polled for changes, component usage is
* checked, wicket tags are not stripped from output and a detailed exception page is used. If
* the type is DEPLOYMENT, component usage is not checked, wicket tags are stripped from output
* and a non-detailed exception page is used to display errors.
*
* Note that you should not run Wicket in DEVELOPMENT mode on production servers - the various
* debugging checks and resource polling is inefficient and may leak resources, particularly on
* webapp redeploy.
*
*
*
* To change the deployment mode, add the following to your web.xml, inside your
* mapping (or mapping if you're using 1.3.x):
*
*
* <init-param>
* <param-name>configuration</param-name>
* <param-value>deployment</param-value>
* </init-param>
*
*
*
* You can alternatively set this as a <context-param> on the whole context.
*
*
* Another option is to set the "wicket.configuration" system property to either "deployment" or
* "development". The value is not case-sensitive.
*
*
* The system property is checked first, allowing you to add a web.xml param for deployment, and
* a command-line override when you want to run in development mode during development.
*
*
* You may also override Application.getConfigurationType() to provide your own custom switch,
* in which case none of the above logic is used.
