Class WebappServletPluginExtension

java.lang.Object

ro.sync.ecss.extensions.api.webapp.plugin.WebappServletPluginExtension

All Implemented Interfaces:

Direct Known Subclasses:

@API(type=EXTENDABLE,
     src=PUBLIC)
public abstract class WebappServletPluginExtension
extends java.lang.Object
implements PluginExtension

This abstract should be extended in order to create a webapp plugin servlet extension.

To register the servlet you just have to declare an extension of type "WebappServlet" in the plugin's plugin.xml file.

For example: <extension type="WebappServlet" class="com.domain.example.WebappServletPluginExtensionImpl"/>

The webapp will register it automatically. The Servlet will map it to an URL which is computed from the path returned by the getPath() method.

For example, if the webapp is available at http://example.com/xml-editor/ and the getPath() method returns mypath, this servlet handles requests for the urls starting with: http://example.com/xml-editor/plugins-dispatcher/mypath/.
