HELP - Nullpointer exception on JCS.getInstance(String).

[Pedro Vaz <pd...@yahoo.com.br>]

Good Morning,

I need help to find the error in my application. It's the first time in 6 month. The application is going to production environment in 3 weeks. I really need to know what happens.

The code is:
-------------------------------------
        private JCS jcsCache;
 (...)
        log.debug("TRY: obter cache: " + regiao);
        jcsCache = JCS.getInstance(regiao);
-------------------------------------

the log is:

------------------------------------
