Hi Bill,
You sent this a while back, and I have to pick it up again.
Would you be able to explain how this would all hook together - are you
saying that Apache could load-balance the request (non-HTTP) and our
extension of JkHandler could handle the request?
cheers,
David

Errr...could you explain why? I was told on the Apache list that it does
work on Windows...what am I missing?
cheers,

Hi,
I've been asking some more questions about restarts on the Apache list, and
was redirected back here...
Does anyone know (David, Mladen?) what will happen to session affinity is
this situation?
ie with Apache in front of several tomcats using mod_jk, when Apache is
restarted "gracefully" us
After some more digging, it *appears* that "apache -k restart" WILL do a
graceful restart of Apache2 on Windoze.
Can anyone confirm this please? And are there any "gotcha's" to watch out
for? Can someone explain exactly how this works? eg if I am in the middle
of a "chunk" (or series) of work
Hi David,
That sounds perfectbut I've got to work on Windows too. Do you know if
there's a way to do it on Win?
thanks!

Is this still true if we were to define "extra" workers that are marked as
disabled at startup? Could we then point them to any new servers as they
are added and enable them without a restart? I know it's not very clean,
but would it work?
We'd *really* like to find a way around having to force
Any ideas or recommendations on this?
cheers,

Hi Mladen,
Sure...we have a system that uses multiple Tomcats (with Apache/mod_jk
upfront, of course). We would like to make it easy for the user to add
another server to the mix. Hence, we'd like to add the new worker to the
Apache config programmatically (we'd like to be able to delete them t
Hi,
Is there any way in the current implementatio to **add** a new worker (for
a new Tomcat instance) dynamically? Using mod_jk status? Another way?
cheers,

Hi,
Are there any docs for the status worker?
I'm struggling to figure out what it can do, and make it do it! Any
pointers?
cheers!

Wow, didn't know this was possible!
This will be perfect for us...except that we need to go through Apache
mod_jk to load-balance requests as they come in, BEFORE they reach tomcat.
Please tell me there is a way to do this?! (and how?!)
cheers,
David
ok...do you know if this can be done programmatically, rather than through
the web page?
Also, is there a timeframe for mod_jk 1.2.9? That sounds perfect if it can
be done programmatically there. We would probably wait for that to be
released...
thanks!!

> Then I wish you all the luck :).
Thanks! It seems a little daunting!
So, exploring other possibilities before I undertake it...
Is there any way to just make a call and update the load factors on the
fly?
Or does the JMX additions provide any way to update things dynamically?
Many thanks,
Hi Mladen,
That sounds feasible...but I have no idea how to do that!!
Would you mind pointing me in the right direction?
- how do we create custom headers? Where?
- how do we get access to the ajp demarshaling?
Sorry for the ignorance! I haven't done any extending of tomcat before...
thanks
Thanks for the reply, Jim...
So, do you know of any other solutions out there? Surely there are many
other people who have been faced with a similar problem?
thanks,
David

Hi,
Thanks very much for the reply.
Ok, how is it possible? What would we need to extend / where would we plug
it in?
Yes, we'd like to balance on CPU usage of tomcat servers that Apache is
load balancing. Or, even, by having each tomcat app communicate with the
balancer to tell it how busy i
Hi,
We need to use Apache to load balance a set of Tomcat servers.
However, we need to use a custom load-balancing algorithm, based on the
usage of those servers.
Is this possible with mod_jk? Would it be easy to extend it? Any other
suggestions?
Many thanks,
David

Whilst on the subject of JspC...does anyone know why no output is obtained when
you run it from the command line?
I am excecuting "java org.apache.jasper.JspC ..." and I never get any output!
Again, is this a bug, or intended behaviour?!
Many thanks,
Dave
Hello,
Does anyone know why JspC pre-compiles all jsp's, even if they have not changed?
I am using Ant to pre-compile and compile my jsps, and it is frustrating that
they are ALL pre-compiled every time.
Is this "intended behaviour" or a bug?
Many thanks,
Dave
Hi. I posted this to the tomcat user group, with no joy.
I am beginning to suspect this is a bug - is it "intended behaviour" that if
jsp's are pre-compiled you cannot use them as a welcome page? Seems very
strange to me if it is!
Thanks,
Dave
