public class retrieve

extends SG8Servlet

A servlet for finding and expressing entries in the database. If the request does not name a context and object, the servlet will throw an exception. If the context is configured to be closed and 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 or filter, a corresponding SG8Search bean is constructed and passed through the session to the search JSP. Otherwise, a filter is configured and the search is performed based on inputs. If nothing is found, the search bean is forwarded to the disavow JSP. Otherwise, if the output is HTML, the results are packed into the search bean and forwarded to either the list JSP for multiple results or the display JSP in the case of a single matching result. If the output is a format other than HTML, the servlet generates the response directly from the results.
