org.eclipse.jetty.osgi.boot.internal.webapp
Class WebBundleTrackerCustomizer

java.lang.Object
  org.eclipse.jetty.osgi.boot.internal.webapp.WebBundleTrackerCustomizer

All Implemented Interfaces:

org.osgi.util.tracker.BundleTrackerCustomizer

public class WebBundleTrackerCustomizer
extends Object
implements org.osgi.util.tracker.BundleTrackerCustomizer

Support bundles that declare the webapp directly through headers in their manifest.

Those headers will define a new WebApplication:

• Web-ContextPath
• Jetty-WarFolderPath

Those headers will define a new app started via a jetty-context or a list of them. ',' column is the separator between the various context files.

• Jetty-ContextFilePath

And generate a jetty WebAppContext or another ContextHandler then registers it as service. Kind of simpler than declarative services and their xml files. Also avoid having the contributing bundle depend on jetty's package for WebApp.
