Sure I remember you Robert. Weren't you out of Australia?
Things are fine. I have had an interest in jBoss for some time, but I was really
stoked the first time I typed "run" and saw all of these services start up
without any exceptions! It reminded me of the early WebLogic 1.0 beta releases.
It is a little short on detailed documentation and examples, but I'm sure that
will come in time.
I understand more about what goes on under the hood on the CORBA servers, but I
must say the main selling point for me currently is the stub-less and imminently
deployable jar files! I haven't ported all of my beans over yet, in fact I've
just started, but once I figure out how all of these configuration files work
together I will suggest we move all of our developers to jBoss. It takes me 5
secs to deploy my beans to jBoss and over 1 minute to deploy under BAS! That
adds up to some real time savings over the course of a week. I'm sure we will
stick with BAS for deployment. It is currently more robust, but I love what I've
seen so far.
Some areas that I hope to gain some more knowledge on in the short term:
1. How are the RMI stubs handled? I am using JDK 1.3 and I assume that the
dynamic proxy classes are being used to isolate me from the stubs, but I assume
they are still there in some form. I am also assuming that they are being
autogenerated at deployment and marshalled to the clients via the http/codebase
mechanism. I haven't tested my program on multiple machines yet. I haven't found
a scrap of documentation or discussion on this yet.
2. Will future directions in the spec force jBoss to give up on RMI? I don't
know...WebLogic seems to have already hedged their bets and bought a CORBA ORB.
3. How do I keep multiple jBoss containers from interfering with each others
beans? And the opposite, how do I get the servers to share beans? I think there
is some documentation on this, but I haven't looked at it closely? I'm not
referring to failover our load balancing, just sharing of beans. I think I will
have to have a shared name service (RMI Registry?) to pull this off, but I
haven't seen any documentation yet.
Other than that, I just have some things that work in my beans under BAS that
don't under jBoss. Most of these seem to be isolated to datasources. I hope to
find out more about all of that this week. :)
I was going to respond to your personal email, but I thought that some of the
facts above would be useful to the group. I apologize to others for the noise.
nice to hear from you,
jim
