Problem with public pages having PL/SQL portlets

Question

I am having problem with a public page which has PL/SQL portlets.
When I try to access that page without doing login, it displays everything but the portlets which are database driven.
Is this the way this public page should behave?
Is there anyway by which I can display data to my public pages from PL/SQL portlets without doing login?
FYI PL/SQL portlets are in portal30 schema.

Yes, it has is_runnable function and it looks like this :
function is_runnable
p_provider_id in integer
,p_reference_path in varchar2
return boolean
is
begin
If p_reference_path is null the caller may be the provider
framework (i.e. the Refresh operation of the Portlet
Repository).
if (p_reference_path is null) then
The following if statement is the security mechanism that
the portlet implements. It does not have any other semantic
meaning. Any portlet is expected to implement their own
security mechanism.
This security mechanism checks if the current user is logged
on or just accessing the portal through the public account.
if (wwctx_api.is_logged_on) then
return true;
else
return false;
end if;
else
If p_reference_path is not null the caller makes this call as
a security check against the portlet instance.
The security mechanism implemented by this portlet for portlet
instances is null so true is returned. Returning this value
indicates that all users have access to this portlet instance.
return true;
end if;
end is_runnable;

What should I need to change with that function? And what exactly is its use?
FYI : The code which I wrote for my portlet is by doing some modification in downloaded service portlet. But I have not altered is_runaable function.
