This is the one peeve I have, and maybe I'm way off, but j2ee has a gaping
hole here without having a safe singleton like mechanism that's container
neutral.
The assumption seems to be that things like this are services, and services
are container specific, like the various jdbc drivers etc..
Jetty is separate but the jboss folks seem to want to treat it as the
official jsp portion of the suite (I agree). I think of jboss as the
controller over all its components so specifying some kind of wait page or
other logic should be at this top level somehow I think.

Sounds like a case for some kind of statement pooling if there is such a
thing. I haven't used j2ee for any of this stuff at this level, but my jdbc
experience has shown me that reusing prepared statements can be the biggest
optimization in many cases (with oracle it was especially so).

That's a good idea, think I will go that way. I still hope for more external
settings (like separating the standard xml files from say an override file
to help between releases).

I thought along the same lines as you. I'm not doing anything myself,
whatever the jetty cmp is doing triggers this, and the site isn't running
yet, this is initialization. I am pretty sure it's using the postgres map,
but it sure seems likely that I have something wrong in this area if it
works
, server
b won't have the session ;)

Objet : Re: [JBoss-user] Httpsession
Sorry, thought the clustering was abstracted, using jetty. I'm just at the
point where I'm not sure of the intended operation. As for more detail, I'm
not sure what would be useful. I have it rigged so I can switch between two
servers, the only two together. Going to server B won't get me the
JBoss version
What have you done to enable httpsession clustering
How are you load-balancing/failing-over between the http nodes
Are you testing using servlets or JSPs
etc

I am beginning to get httpclustering to work. Aside from the overhead of
each server having to have the capacity to hold the total sessions in all
servers, what's the wire traffic like? Yea, I'll sniff it if I have to, this
is just to see if anyone has a quick idea.
I'm guessing it sends out X
I did think of the backplane idea as well. But we also have memory
consumption to think about. If I had four servers evenly balanced, say 100
users on each, I think I would end up with 400 sessions per server. Our
sessions are currently pigs, and that is motivation to fix that!
Perhaps better
I had this same issue. I Think it may be correct
that the ejb doesn't have access to this absolute path you are trying, but not
positive.
Anyway, the utility class generated by xdoclet
makes two string constants, one of them is the short name you used succesfully.
My xdoclet was using
I think a session bean doing threads is not encouraged, but accessing
something else that happens to be threaded could be ok. In my testing it is
ok in jboss right now anyway, I do spawn off threads for multiple requests.
I really don't understand the restriction anyway. So long as your response
it is appropriate to internally
prevent more than one thread working within a transaction as well.

I think this was one of the simplifications adopted by ejbs to make
distributed computing comprehensible...so far I still think its
reasonable.
Still, I'd like to see a scenario.

Wondering what others think about this issue (may
be minor to most of you!)
I use 3.0.0. If I want to run 3.0.1 or 3.0.2, I
can't do it just by plopping in my wars/config. This is because some of the
settingshave changed (jetty packaged differently,
place in the same tree, what you ask would be
reasonable - however

what about java web start? seems simpler to me (I used it, pretty easy, but
can't deliver different versions to different users afaik)

In my situation, yes multiple threads. What I have is a service that I've
bastardized by making a stateless session bean that uses a singleton. When I
connect to it, i end up with many of these beans all calling asynchronously,
so yep, make it thread safe! I don't really know if they would end up
