Class SecurityFilter

java.lang.Object
org.eximeebpms.bpm.webapp.impl.security.filter.SecurityFilter
All Implemented Interfaces:
javax.servlet.Filter
public class SecurityFilter extends Object implements javax.servlet.Filter

Simple filter implementation which delegates to a list of FilterRules, evaluating their SecurityFilterRule#setAuthorized(org.eximeebpms.bpm.webapp.impl.security.filter.AppRequest) condition for the given request.

This filter must be configured using a init-param in the web.xml file. The parameter must be named "configFile" and point to the configuration file located in the servlet context.
