All Implemented Interfaces:

public class SysAdminServlet

extends javax.servlet.http.HttpServlet

implements CGIConstants

The servlet front end to the SysAdmin program. It's counter part is the CGI wrapper WTSACGI.EXE. This servlet gathers and load the SysAdmin request headers and parameters before instantiating the SysAdminRequest and SysAdminResponse objects which are passed to the SysAdmin processRequest method.

The response headers and response itself are handled by the response object.

This class (servlet) will now log to SysAdmin.log if logs are enabled and wt.sysadm.verbose is set to true in the wt.properties.
