public class AccessControlServlet
extends PipelineableServletImpl

This pipeline servlet performs access control for a set of request URL paths, based on the Profile object associated with the request. The servlet is configured with a set of URL-to-AccessController mappings; if the URL being accessed is "guarded" by one of the AccessControllers, the request's Profile object is passed to the AccessController, which decides whether or not access should be allowed. If access is allowed, the request is passed on; if access is denied, the user is redirected to a specified deniedAccessURL.

This servlet comes with a list of AccessAllowedListeners and a list of AccessDeniedListeners, to allow logging or other functions to be performed when access is granted or denied.

AccessControlServlet

public AccessControlServlet()

Method Detail

setUseContextPath

public void setUseContextPath(boolean pUseContextPath)

Set property UseContextPath

Parameters:

pUseContextPath - if true, use the request's context path as part of the access control path. Default is true

isUseContextPath

public boolean isUseContextPath()

Get property UseContextPath

Returns:

if true, use the request's context path as part of the access control path. Default is true

isEnabled

public boolean isEnabled()

Is access control enabled?

setEnabled

public void setEnabled(boolean pEnabled)

Sets whether or not access control is enabled.

getCacheResults

public boolean getCacheResults()

Do we cache results when looking up AccessControllers?

setCacheResults

public void setCacheResults(boolean pCacheResults)

Sets whether to cache results when looking up AccessControllers.

getProfilePath

public java.lang.String getProfilePath()

Gets the Nucleus path of the Profile object.

setProfilePath

public void setProfilePath(java.lang.String pProfilePath)

Sets the Nucleus path of the Profile object.

getAccessControllers

public ServiceMap getAccessControllers()

Returns the AccessControllers used to control access to paths. When a path is processed, the list of access controllers will be searched for the longest match between the access controller key and the requested path, and the corresponding controller will be used.

public void setAccessControllers(ServiceMap pAccessControllers)

Sets the AccessControllers used to control access to paths. When a path is processed, the list of access controllers will be searched for the longest match between the access controller key and the requested path, and the corresponding controller will be used.

Returns the AccessController which should be used to perform access control for the given path.
