h1. Introduction

The following diagrams aim to describe the composition of the Fractal components of Petals ESB.

By naming convention, if not specified, the default name of the interface 'server' is "{{service}}".
To have readable diagrams, some interface links are not drawn:
* the links between the interfaces "{{server}}" of a composite and the interfaces "{{server}}" of its internal components,
* the links between the interfaces "{{client}}" of internal components of a composite and the interfaces "{{client}}" of the composite.
Into a composition, only links between internal components are drawn.

h2. Container Composite

A component {{SharedLibraryLifeCycleImpl}} is intantiated each time a JBI shared library is installed into the JBI container. It is dynamically created.
A component {{ComponentLifeCycleImpl}} and {{Installer}} is intantiated each time a JBI component is installed into the JBI container. It is dynamically created.
A component {{ServiceAssemblyLifeCycleImpl}} is intantiated each time a JBI service assembly is deployed into the JBI container. It is dynamically created.
