public class delete

extends SG8Servlet

A servlet for deleting existing entries from the database. If the request does not name a context and object, the servlet will throw an exception. If the session does not contain an authenticated connection to the given context the path is stored in the session and the request is forwarded to the authenticate JSP. If the input does not define an identifier, an SG8Search bean is constructed and passed through the session to the search JSP. Otherwise, for a GET request a corresponding SG8Discovery bean is constructed and passed through the session to the confirm JSP. For a POST request, typically from the confirm JSP, the identified entry is deleted and its data is returned to the user as an LDIF file.
