Processes the DiGIR request passed in by the servlet. It gets the value of parameter "doc" from the HTTP request as the DiGIR request and dispatches the task to the corresponding class depending on the type of the DiGIR request. If it's a metadata request, it calls the BiotaMetadataHandler.updateMetadata() method to update the resource's information. Otherwise, it calls the BiotaHandlerFactory.getRequestHandler() to get the appropriate BiotaRequestHandler object to find the records that meets the argument in the request's filter element from the resource. It then calls DiGIRProcessor.buildDiGIRResponse() method to build the DiGIR response.

Parameters:

request - the HttpServletRequest received by the servlet

response - the HttpServletResponse of the servlet

Throws:

ServletException

IOExcetion

IOException
