How to turn off the caching in Velocity Engine system?

[Guy Roth]

I am using Spring's Velocity Engine (org.springframework.ui.velocity.VelocityEngineFactoryBean)
The problem is that by default the velocity engine is caching the macros that are defined by this engine so in order to refresh the macro definitions I have to restart the Velocity Engine
Is there any way to disable the caching of the macro?

I tried this: velocityProperties.put("file.resource.loader.cache","false");
but it didn't help.
I also so this link that didn't solve this problem: http://forum.springsource.org/showthread.php?t=16740

Anyone?

Just to update my question:
I tried the following:

velocityEngine.setProperty("file.resource.loader.cache", false);
velocityEngine.setProperty("springMacro.resource.loader.cache", false);
velocityEngine.setProperty("velocimacro.library.autoreload",true);    

and also to perform

 
VelocityEngine engine = getVelocityEngine(); 
engine.init();   

before every time that I do engine.evaluate()...
But the Velocity engine still after all this remember that previous definitions of its macro and doesn't replace them!!!
