Class ContainerTldBundleDiscoverer

java.lang.Object

org.eclipse.jetty.osgi.boot.jasper.ContainerTldBundleDiscoverer

All Implemented Interfaces:

TldBundleDiscoverer

public class ContainerTldBundleDiscoverer
extends java.lang.Object
implements TldBundleDiscoverer

ContainerTldBundleDiscoverer Finds bundles that are considered as on the container classpath that contain tlds. The System property org.eclipse.jetty.osgi.tldbundles is a comma separated list of exact symbolic names of bundles that have container classpath tlds. The DeploymentManager context attribute "org.eclipse.jetty.server.webapp.containerIncludeBundlePattern" can be used to define a pattern of symbolic names of bundles that contain container classpath tlds. The matching bundles are converted to URLs that are put onto a special classloader that acts as the parent classloader for contexts deployed by the jetty Server instance (see ServerInstanceWrapper). It also discovers the bundle that contains the jstl taglib and adds it into the "org.eclipse.jetty.server.webapp.containerIncludeBundlePattern" (if it is not already there) so that the WebInfOSGiConfiguration class will add the jstl taglib bundle into the list of container resources. Eg: -Dorg.eclipse.jetty.osgi.tldbundles=org.springframework.web.servlet,com.opensymphony.module.sitemesh
