Uses of PortletException in javax.portlet

Subclasses of PortletException in javax.portlet
Modifier and Type	Class	Description
`class`	`PortletModeException`	The `PortletModeException` is thrown when a portlet tries to use or set a portlet mode that is not supported by the current runtime environment or the portlet.
`class`	`PortletSecurityException`	A portlet should throw a `PortletSecurityException` when a call fails because of security reasons. Additionally it can be thrown by the portal/portlet-container.
`class`	`ReadOnlyException`	The `ReadOnlyException` is thrown when a portlet tries to change the value for a read-only preference attribute.
`class`	`UnavailableException`	The portlet should throw the `UnavailableException` when the portlet is either temporarily or permanently unavailable to handle requests.
`class`	`ValidatorException`	The `ValidatorException` is thrown by the `validate` method of a PreferencesValidator when the validation of a preference failed.
`class`	`WindowStateException`	The `WindowStateException` is thrown when a portlet tries to use a window state that is not supported by the current runtime environment or the portlet.

Methods in javax.portlet that throw PortletException
Modifier and Type	Method	Description
`protected void`	GenericPortlet.`doDispatch(RenderRequest request, RenderResponse response)`	The default implementation of this method routes the render request to: method annotated with `@RenderMode and the name of the portlet mode a set of helper methods depending on the current portlet mode the portlet is currently in.`
`protected void`	GenericPortlet.`doEdit(RenderRequest request, RenderResponse response)`	Helper method to serve up the `edit` mode.
`protected void`	GenericPortlet.`doHelp(RenderRequest request, RenderResponse response)`	Helper method to serve up the `help` mode.
`protected void`	GenericPortlet.`doView(RenderRequest request, RenderResponse response)`	Helper method to serve up the mandatory `view` mode.
`void`	PortletRequestDispatcher.`forward(PortletRequest request, PortletResponse response)`	Forwards a portlet request from a portlet to another resource (servlet, JSP file, or HTML file) on the server.
`void`	PortletRequestDispatcher.`include(PortletRequest request, PortletResponse response)`	Includes the content of a resource (servlet, JSP page, HTML file) in the response.
`void`	PortletRequestDispatcher.`include(RenderRequest request, RenderResponse response)`	Includes the content of a resource (servlet, JSP page, HTML file) in the response.
`void`	GenericPortlet.`init()`	A convenience method which can be overridden so that there's no need to call `super.init(config)`.
`void`	GenericPortlet.`init(PortletConfig config)`	Called by the portlet container to indicate to a portlet that the portlet is being placed into service.
`void`	Portlet.`init(PortletConfig config)`	Called by the portlet container to indicate to a portlet that the portlet is being placed into service.
`void`	GenericPortlet.`processAction(ActionRequest request, ActionResponse response)`	Called by the portlet container to allow the portlet to process an action request.
`void`	Portlet.`processAction(ActionRequest request, ActionResponse response)`	Called by the portlet container to allow the portlet to process an action request.
`void`	EventPortlet.`processEvent(EventRequest request, EventResponse response)`	Called by the portlet container requesting the portlet to process a specific event.
`void`	GenericPortlet.`processEvent(EventRequest request, EventResponse response)`	The default implementation tries to dispatch to a method annotated with `@ProcessEvent that matches the event name or, if no such method is found just sets the current render parameters on the response. Note that the annotated methods needs to be public in order to be allowed to be called by GenericPortlet.`
`void`	GenericPortlet.`render(RenderRequest request, RenderResponse response)`	The default implementation of this method sets the headers using the `doHeaders` method, sets the title using the `getTitle` method and invokes the `doDispatch` method.
`void`	Portlet.`render(RenderRequest request, RenderResponse response)`	Called by the portlet container to allow the portlet to generate the content of the response based on its current state.
`void`	GenericPortlet.`serveResource(ResourceRequest request, ResourceResponse response)`	Default resource serving.
`void`	ResourceServingPortlet.`serveResource(ResourceRequest request, ResourceResponse response)`	Called by the portlet container to allow the portlet to generate the resource content based on its current state.

Methods in javax.portlet.filter that throw PortletException
Modifier and Type	Method	Description
`void`	ActionFilter.`doFilter(ActionRequest request, ActionResponse response, FilterChain chain)`	The `doFilter` method of the Filter is called by the portlet container each time a action request/response pair is passed through the chain due to a client request for a portlet method at the end of the chain.
`void`	EventFilter.`doFilter(EventRequest request, EventResponse response, FilterChain chain)`	The `doFilter` method of the Filter is called by the portlet container each time a event request/response pair is passed through the chain due to a client request for a portlet method at the end of the chain.
`void`	FilterChain.`doFilter(ActionRequest request, ActionResponse response)`	Causes the next filter in the chain to be invoked, or if the calling filter is the last filter in the chain, causes the portlet at the end of the chain to be invoked.
`void`	FilterChain.`doFilter(EventRequest request, EventResponse response)`	Causes the next filter in the chain to be invoked, or if the calling filter is the last filter in the chain, causes the portlet at the end of the chain to be invoked.
`void`	FilterChain.`doFilter(RenderRequest request, RenderResponse response)`	Causes the next filter in the chain to be invoked, or if the calling filter is the last filter in the chain, causes the portlet at the end of the chain to be invoked.

`void`	RenderFilter.`doFilter(RenderRequest request, RenderResponse response, FilterChain chain)`	The `doFilter` method of the Filter is called by the portlet container each time a render request/response pair is passed through the chain due to a client request for a portlet method at the end of the chain.
`void`	ResourceFilter.`doFilter(ResourceRequest request, ResourceResponse response, FilterChain chain)`	The `doFilter` method of the Filter is called by the portlet container each time a resource request/response pair is passed through the chain due to a client request for a portlet method at the end of the chain.
`void`	PortletFilter.`init(FilterConfig filterConfig)`	Called by the portlet container to indicate to a filter that it is being placed into service.
