Class RequireTag

java.lang.Object

javax.servlet.jsp.tagext.TagSupport

org.openmrs.web.taglib.RequireTag

All Implemented Interfaces:

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

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

Controller for the taglib used on jsp pages. This taglib restricts the page view to currently logged in (or anonymous) users that have the given privileges.

Example use case:

 <openmrs:require privilege="Manage Concept Classes" otherwise="/login.htm" redirect="/admin/concepts/conceptClass.form" />
 

This will demand that the user have the "Manage Concept Classes" privilege. If they don't, kick the user back to the "/login.htm" page. Then, after they log in on that page, send the user to "/admin/concepts/conceptClass.form".
