You can use the Bundle Manager view in order to create bundles from non-OSGi jars, that is, plain jars. When you create a bundle from one or more plain jars, you need an OSGi bundle to host the plain jar. An OSGi bundle that hosts a plain jar, is called a wrapper bundle. A single wrapper bundle is used for publishing one or more plain jars to the server. The Bundle Manager uses different icons to distinguish between plain jars and OSGi bundles.
