Hello,

although the general best practice is to use the public service beans in all instances of customizations to Alfresco, there are some cases where they cannot / should not be used. Due to the dependency of the NodeService (especially the mlNodeService) on the ContentService and its content stores, you have a cyclic dependency if you require the public service bean "NodeService". Instead, you should use the standard service bean "nodeService" - this is the same approach taken by Alfresco for their Enterprise Content Store Selector.
If at all possible, you should always avoid using the ApplicationContext. The only really valid use case I have found so far are HTTP servlet filters that can not be constructed via Spring - unless you use a proxy filter class, which Spring fortunately provides and thus even limits that use case.
