how do I get the handle to my CacheModel...

[Shantanu Upadhyaya <sh...@gmail.com>]

Either my search skills are getting bad or the iBatis documentation is not
adequate.

1. I'd like to call setFlushInterval(..) using a configurable parameter
which can change while the application is running. How do I get the handle
to my already defined Cache model ?

2. How do I add a parameter placeholder in my SQL Map file ...I would want
something like this ?

	<cacheModel id="xxxLRUCache" type="LRU">
		<flushInterval hours="${app.config.value}"/>
		<property name="size" value="1" />
	</cacheModel>
I'm using
org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in my
databaseContext.xml. That works with <bean...>....</bean> . But it will not
work with the SQL Map file.

3. Is there any way to keep the cache ready before being called for the
first time ? Anything in iBATIS to support that ? I could configure a
startup listener with the app server, but I'm just exploring options for
now.

Thanks !

I just don't have the API call you're referring to :
((SqlMapClientDaoSupport) myDaoHandle).get....()

I just don't see the getCacheModel() method. I know it's there but which
handle do I use to call it ? I checked the iBATIS pdfs. Just doesn't contain 
this information.

I don't know how to do that with properties but you can do it 
programmatically by adding a flushstatement:
daoObject.getSqlMapExecutorDelegate().getCacheModel(modelName).addFlushTriggerStatement("Foo.insertFoo");

Never tried it actually but it should work.
