Re: AW: {an alternative}Re: connection pooling
What escapes me is, why is this not more obviously documented? Perhaps it's in the Tomcat docs but I mostly abandoned those some time ago as they are so amazingly detailed and lengthy that unless you want to become a TC guru, which I am inspired to try and be more like, there is simply too much info. How can you post a paragraph like that and expect to be taken seriously? In one breath, you complain about something not being documented, then state that you don't read the documentation because it's too detailed? How can you know what is or isn't obviously documented if you don't read the documentation? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I thought I have read back in this same thread that
he had two Engine under a Service ? Only one
Engine is allowed per Service to fix one problem.

HI Eric,
I have seen the same error your are getting. I am
using tomcat 5.0.28.
Make sure that you have removed the expanded war
directories, from
webapps and ${CATALINA_HOME}/work before
restarting.
Also look inside
those other context.xmls inside
${CATALINA_HOME}/conf/Catalina/localhost
and make sure that they do not define a context with
path=/wms.
Cheers,
nick.

Atishay, the DefaultContext does work once I
comment out the other
Engine element. You mentioned that means something
is wrong with my
Context? So what next?
many thx

If this works them there is something wrong

restart tommy after making changes.
hope it works!!

Re: AW: {an alternative}Re: connection pooling
OK - Got It! Thank you all many times over for your time and help on
this connection pool thing. It is surprisingly difficult to maintain
a stable environment if you're a curious beginner. I clearly need to
get a grip on Tomcat's process BUT it also seems abundantly clear that
docs/how to's for simply getting started with connection pools are
less than optimal. What exactly was my problem? Still not sure and
trying to narrow it down. In the hopes of helping anyone on this
list, here's what FINALLY worked for me?
Again, I'm running TC 5.0.28 on Linux FC2
1. I went in and cleared out ALL my test web-apps, of which I wrote
about 6 different toys via tutorials and on my own. While I don't
nearly understand the reasons for much of the TC directory structure,
I traversed the following directories and 'rm -r -f' all the webaps I
created and no longer wanted with the thinking that somehow they might
be in the way...
the obvious...
CATALINA_HOME/webaps/
the less obvious to me...
CATALINA_HOME/work/StandAlone/localhost
CATALINA_HOME/work/Catalina/localhost
2. This, I'm guessing, is more likely the key but I didn't test
between doing all this. I created a new file, myapp.xml, in...
CATALINA_HOME/conf/Catalina/localhost/
and simply copied the related Context/Context(see prior emails)
from the server.xml in...
CATALINA_HOME/conf/
to this file.
What escapes me is, why is this not more obviously documented?
Perhaps it's in the Tomcat docs but I mostly abandoned those some time
ago as they are so amazingly detailed and lengthy that unless you want
to become a TC guru, which I am inspired to try and be more like,
there is simply too much info.
Okay, I'm off to continue figuring why TC keeps crashing on me.
Hopefully something I did here solved that problem too.
thx again all,
Eric
