      • find

        static <T> T find​(java.lang.Class<T> factoryClass,
                  java.lang.String defaultClassName,
                  boolean tryFallback)
           throws SOAPException
        Finds the implementation Class object for the given factory type. If it fails and tryFallback is true finds the Class object for the given default class name. The arguments supplied must be used in order Note the default class name may be needed even if fallback is not to be attempted in order to check if requested type is fallback.

        This method is package private so that this code can be shared.

        Parameters:
        factoryClass - factory abstract class or interface to be found
        defaultClassName - the implementation class name, which is to be used only if nothing else is found; null to indicate that there is no default class name
        tryFallback - whether to try the default class as a fallback
        Returns:
        the Class object of the specified message factory; may not be null
        Throws:
        SOAPException - if there is a SOAP error

        Parameters:
        clazz - The class to search for
        loader - The ClassLoader to search. If this parameter is null, then the system class loader will be searched
        Returns:
        the URL for the class or null if it wasn't found
