server.xml, Realms, and WARs

[Mark Shaw <MS...@centricasoftware.com>]

I don't think my problem has a solution, but let me ask anyway:

I have a web-app that I deploy as a WAR, and this web-app uses its own Realm
implementation.  In my "server.xml" I specify the host's realm to use my
realm so that my web-app can be dynamically deployed (I don't define a
context entry in server.xml for it).  The problem is if I want to deploy
other web-apps in this host, they too must use the custom Realm.  Is there
anyway to use a custom Realm without explicitly defining it in the
server.xml?  Is there a way to defined my web-app context in my server.xml
and still be able to dynamically deploy it (via a WAR)?

One other question: is there a way to specify classpath parameters for a
dynamically deployed web-app to reference classes that aren't in the sever,
common, web-app libraries?

Thanks for any help with any these questions, I appreciated it.

In Tomcat 4.1.x you can do this, because it supports the ability to define
a "context configuration file" that contains just the <Context> element
(and it's nested content), which can be dynamically deployed along with
your WAR.  You could nest your custom <Realm> element inside this
<Context> element, and it would only apply to this webapp.  See the docs
on the manager webapp for more info.

Tomcat 4.0.x doesn't have any way to do this.

Not without modifying Tomcat sources.
