Method Detail

init

public void init(javax.servlet.ServletConfig config)
          throws javax.servlet.ServletException

Description copied from interface: ErrorHandler

Called by the Davenport servlet to indicate that the handler is being placed into service. Semantics are identical to the Servlet init method; the method is called exactly once after instantiation.

Specified by:

init in interface ErrorHandler

Parameters:

config - a ServletConfig object containing the Davenport servlet's configuration and initialization parameters.

Throws:

javax.servlet.ServletException - If an error occurs during initialization.

destroy

public void destroy()

Description copied from interface: ErrorHandler

Called by the Davenport servlet to indicate that the handler is being taken out of service. Semantics are identical to the Servlet destroy method. This method gives the handler an opportunity to clean up any resources that are being held. After this method has been called, the handle method will not be invoked again.

Specified by:

destroy in interface ErrorHandler

handle

public void handle(java.lang.Throwable throwable,
                   javax.servlet.http.HttpServletRequest request,
                   javax.servlet.http.HttpServletResponse response)
            throws java.lang.Throwable

Called by the Davenport servlet to allow the error handler to process an error. This implementation processes authentication errors according to the configured settings. All other errors are thrown back to the caller for further processing.

Specified by:

handle in interface ErrorHandler

Parameters:

throwable - The error that is being presented for handling.

request - The servlet request object.

response - The servlet response object.

Throws:

java.lang.Throwable - The presented error, if it cannot be processed by this handler.
