- Enclosing class:
- Tomcat
Helper class for wrapping existing servlets. This disables servlet
lifecycle and normal reloading, but also reduces overhead and provide
more direct control over the servlet.

loadServlet
Description copied from class:StandardWrapperLoad and initialize an instance of this servlet, if there is not already at least one initialized instance. This can be used, for example, to load servlets that are marked in the deployment descriptor to be loaded at server startup time.- Overrides:
loadServletin classStandardWrapper- Returns:
- the loaded Servlet instance
- Throws:
ServletException- for a Servlet load error
-
getAvailable
public long getAvailable()Description copied from class:StandardWrapperReturn the available date/time for this servlet, in milliseconds since the epoch. If this date/time is Long.MAX_VALUE, it is considered to mean that unavailability is permanent and any request for this servlet will return an SC_NOT_FOUND error. If this date/time is in the future, any request for this servlet will return an SC_SERVICE_UNAVAILABLE error. If it is zero, the servlet is currently available.- Specified by:
getAvailablein interfaceWrapper- Overrides:
getAvailablein classStandardWrapper- Returns:
- the available date/time for this servlet, in milliseconds since the epoch. If this date/time is in the future, any request for this servlet will return an SC_SERVICE_UNAVAILABLE error. If it is zero, the servlet is currently available. A value equal to Long.MAX_VALUE is considered to mean that unavailability is permanent.
-
getServlet
- Specified by:
getServletin interfaceWrapper- Overrides:
getServletin classStandardWrapper- Returns:
- the associated servlet instance.
-
getServletClass
- Specified by:
getServletClassin interfaceWrapper- Overrides:
getServletClassin classStandardWrapper- Returns:
- the fully qualified servlet class name for this servlet.
