Class PasswordFilter

java.lang.Object
  com.caucho.filters.PasswordFilter

All Implemented Interfaces:

Filter

public class PasswordFilter
extends java.lang.Object
implements Filter

Save a password that the user submits as the session attribute 'java.naming.security.credentials'.

Enable with:

 <filter  filter-name='password' 
          filter-class='com.caucho.filters.PasswordFilter'/>

 <filter-mapping filter-name='password'
                 url-pattern='j_security_check'/>
 

Test with this in a JSP:

 <% if (request.getUserPrincipal() != null) { %>
   username: <%= request.getRemoteUser() %> 
   password: <%= session.getAttribute("java.naming.security.credentials") %>
 <% } %>
 

This will work with a form based login.
