Earlier, they used to be available to applications via * launcher classloader, but now they are available via this class loader (see issue 13612 for more details on this). * * It applies a special rule while handling jars in install_root/lib. * In order to maintain file layout compatibility (see issue #9526), * we add jars like javaee.jar and appserv-rt.jar which need to be excluded * from runtime classloaders in the server side, as they are already available via * PublicAPIClassLoader. So, before we add any jar from install_root/lib, * we look at their manifest entry and skip the ones that have an entry * GlassFish-ServerExcluded: true * * @author Sanjeeb.Sahoo@Sun.COM */ @Service public class CommonClassLoaderServiceImpl implements PostConstruct { /** * The common classloader. */ private ClassLoader commonClassLoader; @Inject APIClassLoaderServiceImpl acls; @Inject ServerEnvironment env; final static Logger logger = LogDomains.getLogger(CommonClassLoaderServiceImpl.class, LogDomains.LOADER_LOGGER); private ClassLoader APIClassLoader; private String commonClassPath = ""; private static final String SERVER_EXCLUDED_ATTR_NAME = "GlassFish-ServerExcluded"; public void postConstruct() { APIClassLoader = acls.getAPIClassLoader(); assert (APIClassLoader != null); createCommonClassLoader(); } private void createCommonClassLoader() { List<File> cpElements = new ArrayList Other Glassfish examples (source code examples)Here is a short list of links related to this Glassfish CommonClassLoaderServiceImpl.java source code file: |
