public final class ServletContextModel
extends Identity

This class is 1:1 representation of server-specific ServletContext and is unaware of OSGi-related representation of a context (like HttpContext and ServletContextHelper).

It represents a web application (that could be described using single web.xml descriptor), while the web elements (like servlets, filters, ...) or configuration (session, JSP config, ...) are contributed possibly by many bundles (bundle-scoped HttpService services or whiteboard service registrations).

Normally, web applications are represented by web.xml files which are parsed by server-specific parsers:

• Jetty: org.eclipse.jetty.webapp.StandardDescriptorProcessor.visit()
• Tomcat: org.apache.catalina.startup.ContextConfig#configureContext(), org.apache.tomcat.util.descriptor.web.WebXmlParser#parseWebXml()

When user registers (through HttpService or Whiteboard) a web element (like servlet), the registration seems unique, but physically, given servlet has to be explicitly registered to all related ServletContextModel (and eventually - ServletContext). It is even more important during unregistration - simple call to HttpService.unregister(String) has to iterate over all mapped ServletContextModel contexts.

Each OsgiContextModel pointing to this class may declare virtual hosts. Actual, server specific context has to be mapped (server-specific method) to all these virtual hosts.

Registered whiteboard element may refer to many OsgiContextModel - pointing to different or the same target ServletContextModel. If two (or more) OsgiContextModel point to the same ServletContextModel, priority (service rank + service id) is checked to find single OsgiContextModel and associated helper.

Method Detail

enableServletModel

public void enableServletModel(ServletModel model)

Marks given ServletModel as enabled, which means it has to be immediately added to relevant mappings, because validation was performed earlier.

Parameters:

model -

disableServletModel

public void disableServletModel(ServletModel model)

Marks given ServletModel as disabled, which means it should no longer be available on active mappings, and should be moved to list of disabled servlets.

This method just removes the model from ServletContextModel, but special care should be taken, because given ServletModel has to be remembered as disabled in ServerModel.

Parameters:

model -

enableFilterModel

public void enableFilterModel(FilterModel model)

Marks given FilterModel as enabled.

Parameters:

model -

disableFilterModel

public void disableFilterModel(FilterModel model)

Marks given FilterModel as disabled.

Parameters:

model -

enableErrorPageModel

public void enableErrorPageModel(ErrorPageModel model)

Mark given ErrorPageModel as enabled

Parameters:

model -

disableErrorPageModel

public void disableErrorPageModel(ErrorPageModel model)

Mark given ErrorPageModel as disabled

Parameters:

model -

enableWebSocketModel

public void enableWebSocketModel(WebSocketModel model)

Marks given WebSocketModel as enabled.

Parameters:

model -

disableWebSocketModel

public void disableWebSocketModel(WebSocketModel model)

Marks given WebSocketModel as disabled.

Parameters:

model -
