Avoid a class to be garbage collected

["Perez Guerrero, Antonio Javier" <AJ...@sadiel.es>]

Hi,
 
Is there any way I can "bind" a class with Cocoon, or make it persistent, so it's never destroyed by the garbage collector?
 
I've a singleton class containing some data structures (basically Maps), which need to be shared between users (so, I can't store them in session). I could write the data to a XML file, but I'd really prefer to avoid it, because the data is going to change very frecuently.
 
Thanks

Then the only thing I have to do is to define the class as a bean in my core.xml (which is loaded from applicationContext.xml). Nice!
 
Thanks a lot Andre
 
PS: I'm using Cocoon 2.2 and Spring 2.5, I forgot to say it.

Hi,

if you rely on Cocoon 2.2, then creating classes with Spring would be
the way to go:

Spring 3.*
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/ch04s04.html#beans-factory-scopes-singleton

Spring 2.5.*
http://static.springframework.org/spring/docs/2.5.x/reference/beans.html#beans-factory-scopes-singleton

While most developers with Spring would prefer XML to define their
beans, one can also do so by annotation.

Cheers,
Andre
