Transfer file from TW Server to remote JavaSDK

Sujith,

You are correct in using the Copy service, but there are a couple of things you need to make sure are configured correctly:

• A FileRepository Thing has been created on the ThingWorx server - in the following code sample (from a custom service) I've named my FileRepository "TestingRepo"
  • sourceRepo is the name of my FileRepository in ThingWorx
  • targetRepo is the name of the Edge Thing defined in the Java SDK

var params = {

  async: false /* BOOLEAN */,

  sourceRepo: "TestingRepo" /* STRING */,

  targetRepo: "FileTransferExample" /* STRING */,

  targetFile: "werd_2014.gif" /* STRING */,

  targetPath: "in" /* STRING */,

  sourceFile: "werd_2014.gif" /* STRING */,

  sourcePath: "Meghan" /* STRING */,

  timeout: undefined /* INTEGER */

};

// result: INFOTABLE dataShape: FileTransferJob

var result = Subsystems["FileTransferSubsystem"].Copy(params);

• The following is the entire Java file (provided in the Java SDK download) that sets up Virtual Directories for a file transfer.
  • If you look at the custom service above to see that we are referencing the targetPath for a directory that is defined in the Java class.

package com.thingworx.javatransfer;

import com.thingworx.communications.client.ClientConfigurator;

import com.thingworx.communications.client.ConnectedThingClient;

import com.thingworx.communications.client.things.filetransfer.FileTransferVirtualThing;

public class FileTransferExample {

  // Substitute your thing name here

  private static final String ThingName = "FileTransferExample";

  public static void main(String[] args) {

  // Create a client config

  ClientConfigurator config = new ClientConfigurator();

  // Basic configuration. See SimpleClient.java for additional info.

  config.setUri("wss://localhost:8443/Thingworx/WS");

  config.setAppKey("8737c3b9-bc65-4ac8-8990-64b565487cd3");

  config.ignoreSSLErrors(true);

  try {

  ConnectedThingClient client = new ConnectedThingClient(config);

  FileTransferVirtualThing myThing = new FileTransferVirtualThing(ThingName, "File Transfer Example", client);

  // Add two virtual directories that will act as the root directories in this

  // application's virtual file system.

  myThing.addVirtualDirectory("in",  "/home/meg/files/in");

  myThing.addVirtualDirectory("out", "/home/meg/files/out");

  client.bindThing(myThing);

  client.start();

  while(!client.isShutdown()) {

  Thread.sleep(5000);

  }

  } catch(Exception e) {

  e.printStackTrace();

  }

  }

}

Let me know if you have any further questions.
