The company I work for has a document management and retrieval system. We are noticing employees use more their smartphones than their laptops, but they cannot access the document management system. So, we are thinking about a CMS, with persistent storage, perhaps developed in Java.

I just started looking into Jease and dotCMS, and also checked here those recommendations in questions like "Best Open Source Java CMS", etc

I find some CMSs too bulky for simple stuff like what we need which is basically document download/edit/upload, and some simple collaboration and personalization stuff.

Smartphones of choice in our workforce are Nokia, Blackberry and IPhone,

The question is: are there java based with persistent db CMSs aimed at Smartphones right now? I need replication of the complete database and run website offline.
