RE: Open Source Object Caching Systems compatible with Struts
Interesting. We implemented our own full object cache for an industrial control system that we are writing. I would be very interested to hear any experiences that folks have with the products mentioned here.

RE: Open Source Object Caching Systems compatible with Struts
Posted by Phase Web and Multimedia <ma...@phase.ws>.
In the system that I am putting together it is more than just database
stuff. Althought the database is involved there is some token replacement
that is going on after the data is extracted and so I don't want the search
and replace happening everytime someone wants to use that object. It won't
be a problem in regards to stale data because it won't impact anything. If
an update is made it doesn't bother me if it takes twenty minutes to post. I
am just looking for a way I can throw some objects into a cache and throw
out data every once in a while. I am not sure the Rowset wrapper is what I
need. This is more than databse rows.. I am constructing objects. I want to
minimize that as much as possible.

RE: Open Source Object Caching Systems compatible with Struts
Posted by Jacob Hookom <ho...@uwec.edu>.
One neat option with DB objects is to implement the design for a
FilteredRowSet as specified by Sun's RowSet. It is/can be separated
from the DB for caching in the application or session and it essentially
acts like a mini-db in memory. One use would be to select * clients and
then allow users to use 'range' or 'like' filters to control the cursor
of the RowSet.
I tried going down the road of object caching but I cam to the
conclusion that any data that required caching was better off just being
cached at the view level or pre-view level as XML or as the static page
content (OSCache). Retaining ACID properties of site when multiple
applications were using the same DB wasn't worth the hassle. A good
DBCP provides excellent speed anyways.
