Q: 

How to store tag cloud on Google App Engine for Java

Hi,

I'm looking to store entities using GAE Java which have 1-many tags. I would like to display a tag cloud, so will need to know how many times each tag occurs (can't use aggregate functions and group by on GAE to do this like I would in SQL). And when I click a tag I would like to retrieve all entities with the selected tag.

Does anyone have any examples of what my Classes should look like to do this optimally and efficiently? Sample JPA code would be great too.

Cheers - Jonathan
