The issue is that you're specifying a postgres driver as a JBoss-wide

Yea, Spring has a new AbstractRoutingDataSource that can route to a
different datasource based on a ThreadLocal. The problem is that the
iBATIS SqlMapClient doesn't know the datasource isn't the same between
calls, so your caching gets horked.
Based on the AbstractRoutingDataSource idea, I wrote
rce from the DAO bean and
inject it by hand in the controller method. I lose the niceness of the
Spring framework for this particular task but I think it should work?

I think he's saying he wants iBATIS to populate already existing beans
in a map rather than create new beans. So basically "Bean b =

would be something like populateMap(statementName, parameterObject, key,

If you use OSCache, you could implement a listener that logs what you

I believe for the OSCACHE type, the iBATIS config is completely ignored and the OSCache values are used.

Make sure you don't include Spring's initialization in your test
measurements. Building a Spring context takes a lot of CPU time, so
it's best to init Sprint and then start gathering data.

Are you saying you have 100 concurrent threads hitting a database
configured with a limit of 50 concurrent connections?
I would use dbcp over the builtin iBATIS one to see what happens.

Both the JDBC test driver and the Spring/iBATIS test driver code would
be helpful. I'd also be interested to see how you're initializing your
Spring context as well.

Just a suggestion: You could configure iBATIS to use JNDI and then
either use your container's JNDI provider or use a standalone one.
I'd also ask if the cost of writing your own iBATIS properties loading
code is cheaper than copying the right properties file into the right
CLASSPATH. That doesn
