Java APIs

One thing I was wondering about while preparing for a presentation was why bidirectional GIOP isn't supported in the 1.5 version of the ORB? The default uni-directional nature of IIOP is the achilles heel with CORBA in terms of the firewall penetration issue. (I think most agree now that making IIOP one-way was a fundamental design mistake. Bidirectional should probably be the default now.) I was just curious why Sun hasn't pursued a firewall friendly version of their version of CORBA. RMI has some support for firewall penetration, it'd be nice to see something similar for CORBA as well and further support in RMI such as full duplex communication. (If you're using Applets or trusted applications, I don't see any reason not to support multiplexed communication. ) It'd be nice to have alternative solutions in available in the JDK for the firewall penetration problem other than HTTP-based solutions. (I know that Jacorb and OpenOrb already support bi-directional GIOP, but it'd be great to have better support in the bundled version as well.)

Thanks!
