EntityBeans Performance

[Ray]

Hi,

Can anyone here share their experiences with EntityBeans? I heard that
there is a performance issue using it since an instance of an
EntityBean represents a row in a table and updating 10,000 rows means
instantiating 10,000 EBs.

Is it a good idea to use EntityBeans?

It's not a good idea to use them just to represents rows in a table. I
think they are meant to encapsulate more 'coarse grained' business
logic/functionality. I guess 'updating 10000 rows' could be an example
for such a function. Even Sun themselves recommend using extra Data
Access Objects for some kinds of Database use.

It's definitely easy to get it wrong with entity beans and really create
performance issues.
