What are all the reasons for which a findAll method returns a 0 collection, we are using JRun4 and the findBy primary key works fine where as all the findAll methods return a collection of size 0.
Thanks,

I assume you mean that it returns an empty collection.
When a finder method returns an empty collection, and it doesn't throw any exception (either FinderException or RemoteException), it means that either it has not found any matches in the database or the SQL query of the finder method is wrong.

Thank you,
That was a problem with the JRun server, once I installed their patch findAll methods started working in a normal way
 
It is sorta covered in the JavaRanch Style Guide.
