File-to-Mail attachment without manipulating the payload

Question

Hello, I have a requirement to pick a file from a file server and send it to receiver as an email attachment as-is. The key is that the system should not read the contents of the file (payload). I'm unsure how to go about this! Any help in this regard is appreciated! Thanks!

Answer 1

I created a Java bean to read the file name available in Adapter-Specific Message Attribute (ASMA) and set it in the payload content type. Here is the code to be put in the process() method in the Java Bean:
                        String fileName;
               Message msg = (Message) inputModuleData.getPrincipalData();
               Payload payload = msg.getDocument();
                    MessagePropertyKey mpk = null;
                    mpk  = new MessagePropertyKey("FileName", "http://sap.com/xi/XI/System/File");
                    fileName = msg.getMessageProperty(mpk);
                           if(fileName == null) fileName="mytestfile.txt";
                         payload.setContentType("text/plain;charset = \"UTF-ISO-8859-1\";" + "name=\"" + fileName + "\"");
               inputModuleData.setPrincipalData(msg);
               } catch (Exception e) {
                    throw new ModuleException(e);
               return inputModuleData;
Thanks to all those that helped me addressing the issue.
