Method Detail

init

public void init(FilterConfig filterConfig)
          throws ServletException
Description copied from interface: Filter
Called by the web container to indicate to a filter that it is being placed into service. The servlet container calls the init method exactly once after instantiating the filter. The init method must complete successfully before the filter is asked to do any filtering work.

The web container cannot place the filter into service if the init method either
1.Throws a ServletException
2.Does not return within a time period defined by the web container

Specified by:
init in interface Filter
Overrides:
init in class AjaxFilter
Throws:
ServletException

destroy

public void destroy()
Description copied from interface: Filter
Called by the web container to indicate to a filter that it is being taken out of service. This method is only called once all threads within the filter's doFilter method have exited or after a timeout period has passed. After the web container calls this method, it will not call the doFilter method again on this instance of the filter.

This method gives the filter an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the filter's current state in memory.

Specified by:
destroy in interface Filter
Overrides:
destroy in class AjaxFilter

handle

public void handle(String method,
                   String message,
                   HttpServletRequest request,
                   AjaxFilter.AjaxResponse response)
Overrides:
handle in class AjaxFilter
