tomcat embedded
Hi
I am searching for some documentation about tomcat embedded.
I am trying to convert a very simple setup (configuration below) to java
code, not using any xml file.
Any link, hint, etc. would be helpful.
Could someone give me a hint?
Regards,
Steffen

I think that's true, but it absolutely lacks documentations or even small
examples!

What do you mean by backing out to the full version?
I am using tomcat since 4.x (several years) as full version, but most
installations are one host, one app only.
Since this application requires tomcat and is seldomly used with anything
else, I think it would make perfect sense to include tomcat embedded into
that app.
One big reason is the ease of upgrades...
Do you have a minimal working example to start with?
Regards,
Steffen

I think the answer is google like hell, that what we ended up doing a long
while ago...
Its not that no one uses it, its everywhere... like inside every application
server out there.
But its complex.
The emebedded TC sits under a "normal TC's" configuration layer, a thing
called digester, which does a hell of a lot more than just read a little
XML.
So if you embedding a simple thing, you'll find there are simple functions
you call for setting up host, and ports and loading webapps, quite an
elaborate model in itself, but when/if you decide to do JNDI or something
not so simple, the embedded documentation out there lacks detail, and it
gets complex.
Its not that easy getting from TC's xml config to what a full TC needs
because the xml is actually a class "waiting to be made".
So embedded TC is not in the same league as the full TC... no easy swap
out.
Its very likely that you'll start with embedded, and end up backing out to
the full version, so a good place to start is actually with the full
versions source.
TC 6's are easier to understand than TC 5's
Have fun ;)

If you're using Tomcat embedded, it's up to you to read and parse any
configuration information you might have, and call the appropriate APIs
to create the necessary Tomcat objects:

Hi
Sorry to ask again, but this is a common feature that I cannot find any
documentation for...
Is there really no documentation for tomcat embedded nor anyone who uses it?
