public  void addInitParameter(String name,
    String value)
Add a new servlet initialization parameter for this servlet.

 public  void addInstanceListener(InstanceListener listener)
Add a new listener interested in InstanceEvents.

 public  void addMapping(String mapping)
Add a mapping associated with the Wrapper.

 public  void addSecurityReference(String name,
    String link)
Add a new security role reference record to the set of records for
this servlet.

 public Servlet allocate() throws ServletException
Allocate an initialized instance of this Servlet that is ready to have
its service() method called. If the servlet class does
not implement SingleThreadModel, the (only) initialized
instance may be returned immediately. If the servlet class implements
SingleThreadModel, the Wrapper implementation must ensure
that this instance is not allocated again until it is deallocated by a
call to deallocate().

 public  void deallocate(Servlet servlet) throws ServletException
Return this previously allocated servlet to the pool of available
instances. If this servlet class does not implement SingleThreadModel,
no action is actually required.

 public String findInitParameter(String name)
Return the value for the specified initialization parameter name,
if any; otherwise return null.

 public String[] findInitParameters()
Return the names of all defined initialization parameters for this
servlet.

 public String[] findMappings()
Return the mappings associated with this wrapper.

 public String findSecurityReference(String name)
Return the security role link for the specified security role
reference name, if any; otherwise return null.

 public String[] findSecurityReferences()
Return the set of security role reference names associated with
this servlet, if any; otherwise return a zero-length array.

 public long getAvailable()
Return 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.

 public String getJspFile()
Return the context-relative URI of the JSP file for this servlet.

 public int getLoadOnStartup()
Return the load-on-startup order value (negative value means
load on first call).

 public String getRunAs()
Return the run-as identity for this servlet.

 public Servlet getServlet()
Return the associated servlet instance.

 public String getServletClass()
Return the fully qualified servlet class name for this servlet.

 public String[] getServletMethods() throws ServletException
Gets the names of the methods supported by the underlying servlet.

This is the same set of methods included in the Allow response header
in response to an OPTIONS request method processed by the underlying
servlet.

 public  void incrementErrorCount()
Increment the error count value used when monitoring.

 public boolean isUnavailable()
Is this servlet currently unavailable?

 public  void load() throws ServletException
Load 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.

 public  void removeInitParameter(String name)
Remove the specified initialization parameter from this servlet.

 public  void removeInstanceListener(InstanceListener listener)
Remove a listener no longer interested in InstanceEvents.

 public  void removeMapping(String mapping)
Remove a mapping associated with the wrapper.

 public  void removeSecurityReference(String name)
Remove any security role reference for the specified role name.

 public  void setAvailable(long available)
Set 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. A value equal to
Long.MAX_VALUE is considered to mean that unavailability is permanent.

 public  void setJspFile(String jspFile)
Set the context-relative URI of the JSP file for this servlet.

 public  void setLoadOnStartup(int value)
Set the load-on-startup order value (negative value means
load on first call).

 public  void setRunAs(String runAs)
Set the run-as identity for this servlet.

 public  void setServletClass(String servletClass)
Set the fully qualified servlet class name for this servlet.

 public  void unavailable(UnavailableException unavailable)
Process an UnavailableException, marking this servlet as unavailable
for the specified amount of time.

 public  void unload() throws ServletException
Unload all initialized instances of this servlet, after calling the
destroy() method for each instance. This can be used,
for example, prior to shutting down the entire servlet engine, or
prior to reloading all of the classes from the Loader associated with
our Loader's repository.
