Method Detail

addMapping

Set<String> addMapping(String... urlPatterns)

Adds a servlet mapping with the given URL patterns for the Servlet represented by this ServletRegistration.

If any of the specified URL patterns are already mapped to a different Servlet, no updates will be performed.

If this method is called multiple times, each successive call adds to the effects of the former.

The returned set is not backed by the ServletRegistration object, so changes in the returned set are not reflected in the ServletRegistration object, and vice-versa.

Parameters:

urlPatterns - the URL patterns of the servlet mapping

Returns:

the (possibly empty) Set of URL patterns that are already mapped to a different Servlet

Throws:

IllegalArgumentException - if urlPatterns is null or empty

IllegalStateException - if the ServletContext from which this ServletRegistration was obtained has already been initialized

getMappings

Collection<String> getMappings()

Gets the currently available mappings of the Servlet represented by this ServletRegistration.

If permitted, any changes to the returned Collection must not affect this ServletRegistration.

Returns:

a (possibly empty) Collection of the currently available mappings of the Servlet represented by this ServletRegistration

getRunAsRole

String getRunAsRole()

Gets the name of the runAs role of the Servlet represented by this ServletRegistration.

Returns:

the name of the runAs role, or null if the Servlet is configured to run as its caller
