Hello Worlds from opensourcestrategies doesnot work

[Bilgin Ibryam]

I just found that Hello world examples do not work.
To get them to work I changed the line
<listener><listener-class>org.ofbiz.securityext.login.LoginEventListener</listener-class></listener>
with
<listener><listener-class>org.ofbiz.webapp.control.LoginEventListener</listener-class></listener>
in the web.xml file of each hello world application. 
Best regards,
