Method Detail

statsReset

public void statsReset()

Resets the current request statistics.

handle

public void handle(String path,
                   Request request,
                   javax.servlet.http.HttpServletRequest httpRequest,

            throws IOException,
                   javax.servlet.ServletException

Description copied from interface: Handler

Handle a request.

Specified by:

handle in interface Handler

Overrides:

handle in class HandlerWrapper

Parameters:

path - The target of the request - either a URI or a name.

request - The original unwrapped request object.

httpRequest - The request either as the Request object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Request object if required.

httpResponse - The response as the Response object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Response object if required.

Throws:

IOException

javax.servlet.ServletException

doStart

protected void doStart()
                throws Exception

Description copied from class: AggregateLifeCycle

Start the managed lifecycle beans in the order they were added.

Overrides:

doStart in class HandlerWrapper

Throws:

Exception
