Q:

Do I really need a managed bean?

Everyting I have read about calling Java from Xpages mentions managed beans.   But I really don't need to save the state of my object.  Do I still need to make my class managed?
What I need to do is to check to see if a password is expired for a user in Directory Services (LDAP).  My plan was to check the state using my LDAP class then store the result in a regular session variable.  So would I still need to use a managed bean?
If not, do I still need to mention the class in faces-config.xml or anyplace  else?

A:

As Henrik said you dont need to use a bean. 
Here a short example how to call a java class directly. Lets say your class is in the package org.testin Path: 
yourApplication.nsf/webContent/WEB-INF/src/
package org.test;

public class Test{

    public static String halloWorld() throws Exception {
        return "HalloWorld";
    }
}

you can call its Methods by using:

<xp:text value="#{javascript:return org.test.Test.halloWorld();}"></xp:text>

You can find more Infos on that in the IBM wiki.
