Install problems: "Error: 500" and exception in MainMenuAction

I'm trying to install Jamm and I am testing with the Tomcat
Http10Connector before I front-end Tomcat with Apache with mod_jk. I've
been following the steps laid out in the HOWTO and I am having a problem
that I don't know how to troubleshoot. When I go to the Jamm URL I get
the following error information:


Error: 500
Location: /jamm/private/index.do

When I look ath MainMenuAction.java:65 I see this: 


    54      public ActionForward execute(ActionMapping mapping,
    55                                   ActionForm actionForm,
    56                                   HttpServletRequest request,
    57                                   HttpServletResponse response)
    58          throws Exception
    59      {
    60          User user = getUser(request);
    61          if (user.isUserInRole(User.SITE_ADMIN_ROLE))
    62          {
    63              return (mapping.findForward("site_admin"));
    64          }
    65          else if (user.isUserInRole(User.DOMAIN_ADMIN_ROLE))
    66          {
    67              return (mapping.findForward("domain_admin"));
    68          }
    69          else
    70          {
    71              return (mapping.findForward("account_admin"));
    72          }
    73      }
    74  }


I'm not a Tomcat or Java hacker so I'm having trouble translating the
exception and relevant line of code into a possible configuration or
software version problem. The system I am installing to has the
following software: 

ii  j2re1.4        1.4.0.99beta-1 Blackdown Java(TM) 2 Runtime Environment, St
ii  ldap-utils     2.1.30-1       OpenLDAP utilities
ii  libldap2       2.1.30-1       OpenLDAP libraries
ii  libservlet2.2- 3.3-2          Servlet 2.2 and JSP 1.1 Java classes and doc
ii  libservlet2.3- 4.0-2          Servlet 2.3 and JSP 1.2 Java classes and doc
ii  slapd          2.1.30-1       OpenLDAP server (slapd)
ii  tomcat         3.3a-4woody1   Java Servlet 2.2 engine with JSP 1.1 support


and the jamm.properties is set to match my slapd as such: 

jamm.ldap.search_base = o=hosting,dc=foobar,dc=com
jamm.ldap.root_dn = cn=admin,dc=foobar,dc=com
jamm.ldap.root_login = admin


I would greatly appreciate any help.
