Class 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

    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      org.osgi.framework.Bundle findJstlBundle()
      Find the bundle that contains a jstl implementation class, which assumes that the jstl taglibs will be inside the same bundle.
      void fixJspFactory()
      Some versions of JspFactory do Class.forName, which probably won't work in an OSGi environment.
      java.net.URL[] getUrlsForBundlesWithTlds​(DeploymentManager deploymentManager, BundleFileLocatorHelper locatorHelper)
      Check the System property "org.eclipse.jetty.osgi.tldbundles" for names of bundles that contain tlds and convert to URLs.
      boolean isJspAvailable()
      Check that jsp is on the classpath

        public boolean isJspAvailable()
        Check that jsp is on the classpath
        Returns:
        true if jsp is available in the environment

      • fixJspFactory

        public void fixJspFactory()
