String SIGNATURE = "process(ModuleContext moduleContext, ModuleData inputModuleData)";
          TRACE.entering(SIGNATURE, new Object[] { moduleContext, inputModuleData });
//          Access the XI message. I.e. this module must be placed in the module chain
           // behind a module that sets an XI message as principal data.
           Object obj = null;
           Message msg = null;
           try {
                     obj = inputModuleData.getPrincipalData();
                     msg = (Message) obj;
                    Message msgg = (Message)inputModuleData.getPrincipalData();     
                    AuditMessageKey amk = new AuditMessageKey(msgg.getMessageId(), AuditDirection.INBOUND);               
                    Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "RenameFile: Module Called");
//               Read the channel ID, channel and the module configuration
                     String cid  = null;
                     String mode = null;
                     String fileName = null;
                     try {
                          // CS_GETMODDAT START
                          mode = (String) moduleContext.getContextData("mode");
                          // CS_GETMODDAT END
                          // CS_GETCHADAT START
                          cid  = moduleContext.getChannelID();
                          Channel channel = new Channel(cid);
//                          channel = (Channel) LookupManager.getInstance().getCPAObject(CPAObjectType.CHANNEL, cid);
                          // Example to access a channel configuration parameter in a module: String someParameter = channel.getValueAsString("YourAttributeName");
                          // CS_GETCHADAT END
//                         Hashtable mp = (Hashtable) inputModuleData.getSupplementalData("module.parameters");

                         fileName = channel.getValueAsString("file.targetFileName");
                         Date todaysDate = new Date(System.currentTimeMillis());
                         fileName = fileName + todaysDate;
                         Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "RenameFile: fileed" + fileName);
                          if (mode == null) {

                          ModuleException me = new ModuleException(e);

                         Audit.addAuditLogEntry(amk, AuditLogStatus.ERROR, "Rerrrd" + me);

           } catch (Exception e) {
                TRACE.catching(SIGNATURE, e);
                if (obj != null)
                     TRACE.errorT(SIGNATURE, "Input ModuleData does not contain an object that implements the XI message interface. The object class is: {0}", new Object[] {obj.getClass().getName()});
                else

                ModuleException me = new ModuleException(e);
                TRACE.throwing(SIGNATURE, me);
                throw me;
          return inputModuleData;
Please refer the above code, it might help you to understand what i m trying to do. I have also included some code that is in comments which I tried by referring the links given by other users but its nt working. Please tell me how to improve my code to set the filename into the <b>reciever file adapter</b>.
