Obsolete servlets

In the layout, servlets can be used to generate the content for the different user interface components such as pages, blocks, and dialogs.

These servlets can be used by:

• The layout manager to generate the user interface, or more precisely, to generate part of the content of a UI component.
• An external API which might be invoked by another app or Ant Tasks in the Publish engine.

Usage

PageSeeder servlets can be invoked on the Web as:

/ps/servlet/{servlet}

Where servlet is the full class name of the Servlet.

See the documentation for each Servlet to know which parameter can or needs to be specified, the HTTP method and other permission requirements.

Layout

Servlets can be referenced in the layout configuration file using the <servlet> element. The @class attribute must be specified and refer to a existing servlet.

See example for a fictional page:

<!-- A sample servlet used for a page -->
<page id="group-acme-test" scope="group" title="Test">
  <url pattern="/acme/test"/>
  <servlet class="com.pageseeder.DoSomething">
    <parameter name="uri"     value="{@uri.id}"/>
    <parameter name="xformat" value="xml"/>
  </servlet>
</page>

Support

Some Servlets have been designed for the layout and shouldn't be used as an API (it might be because their API is not stable or because they rely on a specific state of the system). Other Servlets are more API friendly.

Each Servlet documentation shows clearly in which context it is supported and the level of support.
