setting setShared(true) on EhCacheManagerFactoryBean

[swe]

Hi,

I was looking at Spring's EhCacheManagerFactoryBean and there is a method called setShared(boolean shared). According to the API, setting this value to true means that the cacheManager should be shared (as a singleton at the VM level).

In my case, does this mean that all web applications running on a single Tomcat instance (one server) will share the same cacheManager? This is what I thought so I ran a simple test. I deployed AppA and AppB both using EhCacheManagerFactoryBean (setShared(true)). I populated one of my cache object using AppA and then issued getStatistics() from AppB on the same cache object. I thought that AppB would give me the stats according to the objects I inserted with AppA. This was not the case. What should the expected behaviour be? There might be an error in my code but before I start debugging I just want to make sure I've understood this correctly

Many thanks
S

I did not write the Spring class so I am not sure what it does. Which Spring package is it in?
