public class update

extends SG8Servlet

A servlet for updating attribute values for existing entries in 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. If an entry is identified but no changes are submitted, an SG8Change bean is constructed and passed through the session to the modify JSP. Otherwise changes received from an update form are processed from the request and each affected attribute is updated. The results are packed into the SG8Change bean and sent to the recover JSP.
