Method Details

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 that this Servlet should be mapped to

Returns:

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

Throws:

IllegalArgumentException - if urlPattern is null or empty

IllegalStateException - if the associated ServletContext has already been initialised

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()

Obtain the name of the user / group under which the Servlet has been configured to run.

Returns:

the name of the user / group or null if none has been specified
