how do I configure so as to not call ejbPassivate in 15 minu

[naveen123]

Hi,

I am using a CMP Entity Beans in JBoss 3.2.1 and would like the entity bean(my glorified Singlenton)
not to passivate every 15 minutes of inactive/idle time.

Can I configure this 15 minute time?
If so where do I configure JBoss?

thanks,
naveen
