getServletContainerInitializers

public static Iterable<javax.servlet.ServletContainerInitializer> getServletContainerInitializers(Map<String,String> webFragmentMap,
                                                                                                  List<Object> absoluteOrderingList,
                                                                                                  boolean hasOthers,
                                                                                                  ClassLoader cl,
                                                                                                  boolean servletInitializersEnabled)

Given a class loader, check for ServletContainerInitializer implementations in any JAR file in the classpath

Parameters:

webFragmentMap -

absoluteOrderingList -

cl - The ClassLoader to be used to find JAR files

hasOthers -

servletInitializersEnabled -

Returns:

Iterable over all ServletContainerInitializers that were found

getInterestList

public static Map<Class<?>,List<Class<? extends javax.servlet.ServletContainerInitializer>>> getInterestList(Iterable<javax.servlet.ServletContainerInitializer> initializers)

Builds a mapping of classes to the list of ServletContainerInitializers interested in them

Parameters:

initializers - an Iterable over all ServletContainerInitializers that need to be considered

Returns:

Mapping of classes to list of ServletContainerInitializers interested in them

getInitializerList

public static Map<Class<? extends javax.servlet.ServletContainerInitializer>,Set<Class<?>>> getInitializerList(Iterable<javax.servlet.ServletContainerInitializer> initializers,
                                                                                                               Map<Class<?>,List<Class<? extends javax.servlet.ServletContainerInitializer>>> interestList,
                                                                                                               org.glassfish.hk2.classmodel.reflect.Types types,
                                                                                                               ClassLoader cl,
                                                                                                               boolean isStandalone)

Given an interestlist that was built above, and a class loader, scan the entire web app's classes and libraries looking for classes that extend/implement/use the annotations of a class present in the interest list

Parameters:

initializers - Iterable over all ServletContainerInitializers that were discovered

interestList - The interestList built by the previous util method

cl - The classloader to be used to load classes in WAR

Returns:

Map<Class<? extends ServletContainerInitializer>, Set<Class<?>>> A Map of ServletContainerInitializer classes to be called and arguments to be passed to them
