A very interesting tool is nearly available with the PEtALS ESB;

This tool, JASMINE (http://wiki.jasmine.objectweb.org/xwiki/bin/view/Main/News), allows to deploy PEtALS instances on servers, and configure them to work together.

You can specify domains on your PEtALS topology, and all the features of the network version of PEtALS.

There was a prerequisite with JASMINE in the past, which was a little bit constraining; you needed to manually deploy Jasmine nodes on servers before the JASMINE framewok was abble to deploy things on these servers

But now, JASMINe nodes can be deloyed from the JASMINe console thanks to the integration of a deployment engine: FDF;

I don’t see this new feature for now, but it is the last thing that was missing in JASMINE to be fully useable for massive deployments.

An article about ESB physical topologies.

The article shows the benefits of using a federated ESB, deployed over the whole enterprise.

Of course, PEtALS support a such deployment ! ;-)

I suggest you an article I wrote with Marc DUTOO (from OpenWide company). This article deals with how to use an ESB for integration.
From a hard coded approach, to orchestration, we introduce various level of integration.

This article I wrote show an example of a value added service built on existing services.

This case study is an online reservation system that allows you to book a flight and an hotel room for your vacations... ;-)

The following article introduces the JBI concepts that you may need to understand before using a JBI server for SOA considerations
