tDropboxPut – Docs for ESB 5.x

tDropboxPut

1. In the Integration perspective of the Studio, create
   an empty Job from the Job Designs node in
   the Repository tree view.

   For further information about how to create a Job, see Talend Studio User Guide.

2. In the workspace, enter the name of the component to be used and select this component from the list that appears. In this scenario, the components are tDropboxConnection, tFixedFlowInput, tFileOutputDelimited, tFileInputRaw and two tDropboxPut components.

   The tFixedFlowInput component generates some
   data to be uploaded to Dropbox in this scenario. In the
   real-world case, you can use other components such as tMysqlInput or tMap in the
   place of tFixedFlowInut to design a
   sophisticated process to prepare your data to be handled.

3. Connect tFixedFlowInput to tFileOutputDelimited using the Row >
   Main link.

4. Do the same to connect tFileOutputDelimited to one of the two
   tDropboxPut components and connect
   tFileInputRaw to the other tDropboxPut component.

5. Connect tDropboxConnection to tFixedFlowInput using the Trigger > On Subjob Ok link. Then connect tFixedFlowInput to tFileInputRaw using the same type of link.

1. Double-click tDropboxConnection to open its
   Component view.

   

2. In the Access token field, paste the token that you have
   generated via the App console of Dropbox for accessing the Dropbox App
   folder to be used.

Defining the input data

1. Double-click tFixedFlowInput to open its
   Component view.

   

   In this scenario, only three rows of sample data are created to indicate three countries
   and their calling
   codes.

   33;France 86;China 81;Japan

   1 2 3

   33;France 86;China 81;Japan

2. Click the […] button next to Edit
   schema to open the schema editor.

3. Click the [+] button twice to add two rows and in the
   Column column, rename them to code and country, respectively.

   

4. Click OK to validate these changes and accept the
   propagation prompted by the pop-up dialog box.

5. In the Mode area, select the Use
   Inline Table radio button. The code and the country
   column have been automatically created in this table.

6. Enter the sample data mentioned above in this table.

Defining the output stream

1. Double-click tFileOutputDelimited to open its
   Component view.

   

2. Select the Use output stream check box to write the data to
   be outputted into a given output stream.

3. In the Output stream field, enter the code to define the
   output stream you need to write data in. In this scenario, it is the output
   stream of the tDropboxPut_1 component
   linked with the current component. Thus the code used to write the data
   reads as
   follows:

   ((java.io.OutputStream)globalMap.get("tDropboxPut_1_OUTPUTSTREAM"))

   1	((java.io.OutputStream)globalMap.get("tDropboxPut_1_OUTPUTSTREAM"))

   Note that in this example code, the tDropboxPut
   component has the number 1 as its affix,
   which represents its component ID distributed automatically within this Job.
   If the tDropboxPut component you are using
   has a different ID, you need to adapt the code to that ID number.

4. Click Edit schema to verify that the
   schema of this component is identical with that of the preceding tFixedFlowInput component. If not so, click the
   Sync columns button to make both of the
   schemas identical.

1. Double-click the tDropboxPut component linked with
   tFileOutputDelimited to open its
   Component view.

   

2. Select the Use existing connection check box to reuse
   the connection created by tDropboxConnection.

3. In the Path field, enter the path pointing to the file
   you need to write data in, with a slash (/) at the beginning of the path.
   For example, enter /calling_code.csv.

4. In the Upload mode area, select the Rename if Existing radio button.

5. Select the Expose As OutputStream radio button to expose
   the output stream of this component so that the other component, tFileOutputDelimited in this scenario, can write
   data in the stream.

1. Double-click tFileInputRaw to open its
   Component view.

   

   This component is used to read a picture named esb_architecture.png into the data flow. In the real-world
   practice, this file can be of many other formats, such as pdf, xls, ppt or
   mp3.

2. In the Filename field, enter the path or browse to the
   file you need to upload.

3. In the Mode area, select the Read
   the file as a bytes array radio button.

1. Double-click the tDropboxPut component linked with
   tFileInputRaw to open its Component view.

   

2. Select the Use existing connection check box to reuse
   the connection created by tDropboxConnection.

3. In the Path field, enter the path pointing to the file
   you need to write data in, with a slash (/) at the beginning of the path.
   For example, enter /architecture.png.

4. In the Upload mode area, select Rename if existing.

5. Select the Upload incoming content as
   file radio button. This displays the Edit schema button to allow you to view the read-only schema
   of this component.
