Provisioning and bundle repositories
WebSphere provides good support for application provisioning by shipping with an
OBR
bundle repository implementation, and allowing users to configure third-party
repositories.
BUILT-IN BUNDLE REPOSITORY
WebSphere includes an integral bundle repository with the application server (see fig-
ure 13.6). This allows common utility bundles to be provisioned without having to set
up a third-party bundle repository. Provisioning bundles, rather than packaging them
with applications, reduces application footprint and makes rolling out new versions of
common bundles easier.
CONFIGURABLE EXTERNAL BUNDLE REPOSITORY
WebSphere can provision bundles from any bundle repository that complies with the
draft
RFC112
(
OBR
) specification (discussed in chapter 7). All that's required is to con-
figure a name and
URL
for the external repository.

The Fancy Foods bundles installed in the WebSphere bundle repository. This allows them
to be automatically provisioned and shared between several applications.
