Class AclTag

java.lang.Object

javax.servlet.jsp.tagext.TagSupport

org.acegisecurity.taglibs.authz.AclTag

All Implemented Interfaces:

Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class AclTag
extends javax.servlet.jsp.tagext.TagSupport

An implementation of Tag that allows its body through if some authorizations are granted to the request's principal.

Only works with permissions that are subclasses of BasicAclEntry.

One or more comma separate integer permissions are specified via the hasPermission attribute. The tag will include its body if any of the integer permissions have been granted to the current Authentication (obtained from the SecurityContextHolder).

For this class to operate it must be able to access the application context via the WebApplicationContextUtils and locate an AclManager. Application contexts have no need to have more than one AclManager (as a provider-based implementation can be used so that it locates a provider that is authoritative for the given domain object instance), so the first AclManager located will be used.
