MBean restrictions?

[danl_thompson]

Is an MBean in anyway restricted as EJBs are? Can an MBean a) have non-final static vbls? b) use synchronized blocks? c) use file access and java.io ? d) listen on sockets? e) start and wait on out-of-process threads for example runtime.exec()?

If not, can can an EJB call a MBean that does any of these things on its behalf? Or would it be slight-of-hand, hiding the prohibitied behavior in what is effectively a helper class?

No they are not restricted as MBean is not an established J2EE component model.

OK, then can EJBs call functions on MBeans? And if EJBs do call MBeans do the MBeans have to follow the EJB restrictions?

thanks again!

Yes they can. The EJB restrictions apply only if you want to follow them.

Sweet! So JBoss is actually far less restrictive than other J2EE containers... how nice is that? You guys rock the house!
