Hi,
I am currently hacking a bit on some IIOP-related code
for JBoss:
0) In package org.jboss.iiop, I have written a simple MBean
that serves an ORB and POA in JNDI "java:" for JBoss to
use.
1) In package org.jboss.rmi, I have written some code for
analysing java classes to get the metadata needed for
a compile-less RMI-IIOP mapping.
2) In package org.iiop.rmi.ir, I have written the code for
a CORBA Interface Repository that can be easily filled
in with some remote interfaces. This IR is meant to
publish the metadata of the RMI-IIOP mapping in the
usual CORBA IR format.
3) In package org.iiop.rmi.server, I have written some code
for supporting an IIOP-based container invoker for JBoss.
This contains code for unmarshaling invocation arguments,
and marshaling return values and exceptions thrown.
This is all very unstable/unfinished/untested, and I am not
yet really sure what way this is going, so I have committed
nothing yet.
But with sufficient luck, maybe JBoss will end up supporting
IIOP with the same ease as it currently supports JRMP.
It needs a fairly new CORBA implementation for Java to run,
and it seems that the one from Sun it not even complete
enough to compile.
Currently, I am testing my code on JacORB (www.jacorb.org),
with a little hack I recently posted to the JacORB mailing
list for support of the value type TypeCodes, and support
for Value ValueMember and ValueBox IR entry types.
Unfortunately, JacORB will not be able to support the
transfer of value types over IIOP until late August, and
that is needed for our bean invocations over IIOP.
>From manual inspection of published test interface
repositories from 2) above using the JacORB irbrowser, it
looks like 1) and 2) are pretty complete. (Still some
confusion about abstract IDL interfaces: Looks like OMG
did some last-minute spec-changes, and that they are
currently publishing IDL that does not conform fully to
their own spec.)
But 3) is only half-finished.
I haven't even thought about the client side of things,
but the interface repository is so complete that it should
be possible (in theory) for a client to work with no code
downloading at all.
For non-Java clients some kind of bootstrap (CORBA naming
service?) would be needed. Probably it would also be nice
if the IR could print out IDL so that the metadata is
available in IDL format for non-Java clients.
I _could_ commit this half-baked code, but then I would
have to also commit a hacked version of jacorb.jar to
JBoss. Probably it would be better to wait until JacORB
officially supports this (planned for the end of August).
If anybody is interested, it would probably be better if
I uploaded the code to the web.
Best Regards,
Ole Husgaard.
