Initialize bean for auto-login

[Aaron Bartell]

Hi all,
I am trying to initialize a backing bean property using the param 
feature.  Here is my faces config entry:

   <managed-bean>
       <managed-bean-name>LoginCtl</managed-bean-name>
       
<managed-bean-class>com.mowyourlawn.controller.LoginController</managed-bean-class>
       <managed-bean-scope>session</managed-bean-scope>
        <managed-property>
           <property-name>user.name</property-name>
           <property-class>java.lang.String</property-class>
           <value>#{param.profile}</value>
       </managed-property>       
        <managed-property>
           <property-name>user.password</property-name>
           <property-class>java.lang.String</property-class>
           <value>#{param.password}</value>
       </managed-property>           
   </managed-bean>

I am implementing an auto login feature where a site not under my 
control can pass in a user and password on the query string and then I 
will auto execute the page and validate the information passed to me. I 
was trying to find the rules for what you can specify in the 
property-name tag but have come up empty handed.  It seems that it 
doesn't like anything that is a custom object (eg user.password where 
user is a User.java object and password is a String object)

Thoughts on how to make this work?
Thanks,
