Deregister provider in Portal

Question

I have created a custom database portlet using Portal 3.0.9.8.3 and have registered the same to portal.
Now I have added customizations (personalization) to save user preferences. However if I just compile the portlet code none of the preference paths and preferences get created and exceptions are thrown.
The only way to get it working is to remove original provider and register new provider again.
Question is how do I do this programatically since
when i remove provider using the following code I still see the provider and portlet although no exception is thrown.
declare
l_provider wwpro_api_provider_registry.node_provider_record;
begin
l_provider := wwpro_api_provider_registry.find_provider(p_name =>'XXC_LOCAL_PREF',p_language => wwnls_api.AMERICAN);
dbms_output.put_line(l_provider.id || 'Provider id ');
wwpro_api_provider.deregister_provider(p_provider_id => l_provider.id );
commit;
exception when others then
dbms_output.put_line('Exception during portlet registration');
end;

Sudip,
I want to know if you registered the portlet manually. If so, please can you tell me how you did it.
Thanks,
Paami.
