I think that is a vendor specific problem - which web server are you using?
From the deployment descriptor docs in the servlet API it looks to me like the element <distributable/> simply marks the application as having been programmed so that it can be distributed. I don't see a <distribute> tag in the API for servlet 2.3

I regret to say that I have never had to configure such a distributed system. This is the kind of thing that J2EE is supposed to make very easy. The premier open source implementation of J2EE is called JBoss. Go to the JBoss web site for more information. The user community for JBoss is huge.

If I read this right, what you're asking about is what's called "clustering".
WebLogic supports it and I think WebSphere does. I don't know specifics about any others. The exact degree of clustering and set of features supported is very much dependent on what brand and release you are using.
Outside of J2EE, the Apache web server is often run in multiples using DNS round-robin.

Configuration can mean many things. WebLogic comes ready to run a number of demo webapps, so in that sense it's preconfigured. Many configuration options may be done via the WebLogic control panel webapp.
This is a large and complex system, which is only to be expected from one of the premier web application server products, so there's simply no way to give all-inclusive instructions, especially in the space of an online forum. However there's extensive on-line documentation, and while not everyone agrees, I think it's pretty good.
Good places to get assistance are the WebLogic newsgroups hosted by BEA and the JavaRanch BEA/WebLogic Forum.
