accessing versioning information?

[esource]

how can we access versioning information regarding content/documents with java?

[savic_prvoslav]

org.alfresco.web.bean.repository.Repository.getServiceRegistry(FacesContext.getCurrentInstance()).getVersionService().getCurrentVersion(nodeRef)
   
   org.alfresco.web.bean.repository.Repository.getServiceRegistry(FacesContext.getCurrentInstance()).getVersionService().getVersionHistory(nodeRef)‍‍‍

hope this helps.
