5. In the FileWriterConfig dialog box, provide the following values and clock click OK:
   1. File Name: The name of the file to which the input data has to be written. If the file with this name does not exist, a new file is created
   2. Target Directory: Provide the location to save the file.
   3. Working Directory: Location to save the file during intermediate processing.
   4. Error Directory: Location to save the file in case the processing does not get successful.

1. Connect the FileWriter with RESTStub in the following manner:
   1. RESTStub output port to FileWriter input port.
   2. FileWriter output port to RESTStub input port.

2. Replace the names of 'route1' and 'route2' with 'UploadRequest' and 'UploadResponse' respectively to match the scenario. After clicking on the respective route, do any of the following to change the name:
   
   1. Press F2, change the name and click OK.

2. In the Output Structures panel, click Status under Response. 'Status' appears in Funclet View panel.
   
   
   Figure 16: Working on Funclet View
    
3. In the Funclet View panel, drag the function element Constant to the Funclet easel. Double-click it, edit the name as '200' and click OK.

4. Connect the source node of the constant '200' to the destination node of Status.
   
   
   Figure 18: Connecting Constant with new name '200' to the Status element
    
5. Similarly, connect source node of the constant 'application/jasonjson' to the destination node of MediaType (select from Representation under Output Structures panel).

6. Add the following elements to the Funclet easel in the following manner:
   1. Click ANY present under Element in Output Structures panel
   2. Drag FullName present under FileInfo in Input Structures panel.
   3. Add two Constant functions from String Functions and change their name as below:
      
      • { "FilePath" : "
      • " }
   4. Add Concat from String Functions.
      
      
      Figure 20: Adding Constant functions, FullName from FileInfo, Concat and ANY
       
7. Connect the elements added in Step#6 in the following order:
   1. Source node of { "FilePath" : " to the destination node '1' of Concat.
   2. Source node of FullName to the destination node '2' of Concat. Destination node '3' appears after this conncetion.
   3. Source node of " } to the destination node '3' of Concat.
   4. Source node of Concat to the destination node of ANY.
   Adding the elements in the above order helps to generate Display output in the following format:
   { "FilePath" : "<TARGET_FILE_PATH>" }:

1. Add the FileReader component from File category in the Micro Service Palette to the Fiorano Orchestrator.
   
   
   Figure 27: Adding FileReader component to REST_Client_Example event process
    
2. Double-click the FileReader component to open Configuration Property Sheet (CPS).
3. In the Interaction Configuration dialog box, select the 'Is input Binary ?' checkbox to write the data as bytes and click the FileReader Configuration Ellipsis button.
   
   
   Figure 28: Selecting Binary File
    
4. In the FileReaderConfig dialog box, provide the following values and click OK:
   1. File Name: The name of the file to be read. A pattern of file names can also be provided using wildcard character * (asterisk symbol).
      Example: *.* includes all the files and *.jpg includes the files with .jpg extension.

   2. Source Directory: The directory which holds the file(s) to be read. All the files in this directory whose names match the pattern specified for the File name property will be processed.

      Info
      Working Directory and Error Directory are optional. Select the Use Working Directory check box to use working directory.
