How To Logout From ADF Application Programmatically In JDeveloper 11g ?

As you might know already, from logging out to ADF Application you can set 'Destination' property of af:goLink to your desired page.

 <af:goLink text="Logout" id="gl2"   
     destination="/adfAuthentication?logout=true&amp;end_url=/faces/login.jspx"  
     accessKey="L" shortDesc="Logs-out current user session."/>  

The Logout can also handled programmatically by server side code in managed-bean.
To do so, af:commandLink can be used something like below.

 <af:commandLink text="Logout" id="cl2"   
   action="#{dataentry_bean.onLogout}"  
   immediate="true"  
   shortDesc="Logs-out current user session."  
   accessKey="L"/>  

Setting Immediate=true is optional, and it is for bypassing any validation on page.


The managed bean code -

 import javax.faces.context.ExternalContext;  
 import javax.faces.context.FacesContext;  
 import javax.servlet.http.HttpServletRequest;  
 import javax.servlet.http.HttpSession;  
 import weblogic.servlet.security.ServletAuthentication;  
   
   public String onLogout(){  
     FacesContext fctx = FacesContext.getCurrentInstance();  
     ExternalContext ectx = fctx.getExternalContext();  
     String url = ectx.getRequestContextPath() + "/adfAuthentication?logout=true&end_url=/faces/login.jspx";  
       
     HttpSession session = (HttpSession)ectx.getSession(false);  
     session.invalidate();  
       
     HttpServletRequest request = (HttpServletRequest)ectx.getRequest();  
     ServletAuthentication.logout(request);  
     ServletAuthentication.invalidateAll(request);  
     ServletAuthentication.killCookie(request);  
       
     try{  
       ectx.redirect(url);  
     }  
     catch(Exception e){  
       e.printStackTrace();  
     }  
     fctx.responseComplete();  
       
     return null;  
   }
