Is CORBA outdated?

I'm just learning about midleware in class, and our teacher has told us about CORBA. Doing a bit of research, I've found that the last version (CORBA 3) was released in 2002, which seems quite old in the computers science (well, in fact I know there is also CORBA 3.3, released in 2012, but..)

So there's my question: is CORBA outdated? Are there any better methods to communicate different systems?

I.E: we've been learning a bit of RMI too, since JVM let us to only worry about the communication itself.

Thanks in advance
