Best way to subscribe multiple customers to list?

Question

Question:
I have a straight forward task ahead of me. I need to subscribe roughly 100 existing customers to a new email mailing list. What's the best way to do this in BC? When i say existing customers I mean they are in the BC system already, so I don't want to export and then re-import those customers.
Answer:
You cna use Customer reports for that. Create a report of those customers and filter it according to your needs, then on the second last step of report creation click on Add Customers To button and choose a marketing list you wish to add them to.

Answer 1

I would use a Map<String, Set> or Map<String, List> (using Java 5 generics notation here to show clearly what is in the map, but using generics is not required).
The keys in the map are the company names, the values are Sets or Lists of brand names.
This snippet will get keys and values from a Map called companyBrandsMap:<c:forEach var="mapElement" items="${companyBrandsMap}">
   Company: <c:out value="${mapElement.key}"/><br>
   Brands:<c:forEach var="listElement" items="${mapElement.value}">
     <c:out value="${listElement}"/><br>
   </c:forEach><br>
</c:forEach>This code just prints the values, you can put your JavaScript code around that.
