PEGA need to send excel files in zipped format to SOV service in the request. The service is currently only accepting zipped excel files and sending back zipped xmls after extraction. In order to be able to reuse the same service, CAST will require to zip the excel files in request to processDocument and unzip the xml files in response of getExtractedDetailsById. So is there any PEGA OOTB available to zip and unzip or we need to build a Custom Java. Need suggestion.
