Domain objects with guid as id

[fanfy]

I want to use spring security for managing the acls in a document management system implemented in jcr. I have a Document abstraction that contains the guid of the jcr node. My service layer works only with Document so this is a good candidate for acl management. But I don't have a long id. What classes I need to overwrite and what are the recommendations here? Thank you.

nobody answer this question since 2008? I have same issue here.
