}
The above code works fine to load pdf file into S3 when I run it from IntelliJ IDE. I want this code to move to Pentaho "User Defined Class", when I do that it throws error - " Imported class "com.amazonaws.auth.AWSStaticCredentialsProvider" could not be loaded"
How do I resolve that? My ultimate goal is to load a .pdf or .zip file into S3 using pentaho.
Thank you for your time.

Your have written nice code which is working as well. You just need to keep aws-java-sdk jar to your data-integration/lib location.
You can download sdk jar file from Here
You can look my KTR also from Here where I have included your code and make small changes to workable your code in User-defined-java-class in PDI

Create shareable link for all files in Dropbox using Dropbox API

I have around 100 files in my Dropbox account I am trying to make shareable link for all of the files using Dropbox API.
Tried using
DbxClient = new DbxClient(config, accessToken);
client.createShareableUrl(path);
but got an error on DbxClient cannot find symbol, or class not found.
import com.dropbox.core.DbxRequestConfig;
import com.dropbox.core.v2.*;
import static com.dropbox.core.v2.files.AlphaGetMetadataError.path;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
public class DBX {
static boolean doYouWantMeToUpload = false;
private static final String ACCESS_TOKEN = "My access token here I removed it";
public static void main(String args[]) throws DbxException, FileNotFoundException, IOException {
// Create Dropbox client
DbxRequestConfig config = DbxRequestConfig.newBuilder("dropbox/java-tutorial").build();
DbxClientV2 client = new DbxClientV2(config, ACCESS_TOKEN);
// Get current account info
FullAccount account = client.users().getCurrentAccount();
System.out.println(account.getName().getDisplayName());
if(doYouWantMeToUpload == true){
// Get files and folder metadata from Dropbox root directory
ListFolderResult result = client.files().listFolder("");
while (true) {
for (Metadata metadata : result.getEntries()) {
System.out.println(metadata.getPathLower());
}
if (!result.getHasMore()) {
break;
}
result = client.files().listFolderContinue(result.getCursor());
}
// Upload "test.txt" to Dropbox
try (InputStream in = new FileInputStream("test.txt")) {
FileMetadata metadata = client.files().uploadBuilder("/test.txt")
.uploadAndFinish(in);
}
// Get shareable link for a file
DbxClient = new DbxClient(config, ACCESS_TOKEN);
client.createShareableUrl(test.txt);
}
}
}
I want to get shareable link for all files in my Dropbox.
I followed these instructions in Dropbox GitHub.

You're attempting to use the old createShareableUrl which is for Dropbox API v1, which is now retired.
You should instead use Dropbox API v2, via DbxClientV2, like you do for the other calls in your code.
Specifically, to create a shared link, you should use createSharedLinkWithSettings. That would look something like:
DbxClientV2 client = new DbxClientV2(config, ACCESS_TOKEN);
client.sharing().createSharedLinkWithSettings(path);

How to get query result in Json form using Java API of Google Bigquery

I am using Google Bigquery V2 Java API. I am not able to find a way to get query results in JSON format.
In Bigquery Web UI we can see this JSON and Table form of results. see scrrenshot.
Is there any way to get the GetQueryResultsResponse as JSON, using Java API.

One option is to apply the TO_JSON_STRING function to the results of your query. For example,
#standardSQL
SELECT TO_JSON_STRING(t)
FROM (
SELECT x, y
FROM YourTable
WHERE z = 10
) AS t;
If you want all of the table's columns as JSON, you can use a simpler form:
#standardSQL
SELECT TO_JSON_STRING(t)
FROM YourTable AS t
WHERE z = 10;

I'm using a service account to access the BigQuery REST API to get the response in JSON format.
In order to use a service account, you will have to go to credentials (https://console.cloud.google.com/apis/credentials) and choose a project.
You will get a drop down like this:
Create a Service account for your project and download the secret file in the JSON format. Keep the JSON file in your file system and set the path to it. Check below image to set the file path:
So, now all you have to do in is use JAVA client api to consume the Big Query REST API.
Here's is a simple solution that I've been using for my project.

// Set the content of the request.
Dataset dataset = new Dataset().addLabel(QUERY, QUERY_HACKER_NEWS_COMMENTS);
HttpContent content = new JsonHttpContent(JSON_FACTORY, dataset.getLabels());
// Send the request to the BigQuery API.
GenericUrl url = new GenericUrl(String.format(QUERY_URL_FORMAT, projectId, accessToken));
logger.debug("URL: " + url.toString());
String responseJson = getQueryResult(content, url);
logger.debug(responseJson);
}
private static String getQueryResult(HttpContent content, GenericUrl url) {
String responseContent = null;
HttpRequestFactory requestFactory = HTTP_TRANSPORT.createRequestFactory();

request.setHeaders(
new HttpHeaders().set("X-HTTP-Method-Override", "POST").setContentType("application/json"));
HttpResponse response = request.execute();
InputStream is = response.getContent();
responseContent = CharStreams.toString(new InputStreamReader(is));
} catch (IOException e) {
logger.error(e);
}
return responseContent;
}
private static String generateAccessToken() {
String accessToken = null;
if ((System.currentTimeMillis() > credential.getExpirationTimeMilliseconds())) {
accessToken = credential.getRefreshToken();
} else {
accessToken = credential.getAccessToken();
}
System.out.println(accessToken);
return accessToken;
}
}
Following is the Github link to the code: https://github.com/vslala/BigQueryRestSample
It is just a demo project to fetch JSON data from the BQ REST API. Do not use it in your project directly.
Let me know if you have any questions.

One problem is that the setTitle method does not exist any more in the latest Java API. How do I set the title of a file now?

Some changes in above code

Drive.Files.Insert -> Drive.Files.Create
drive.files().insert(fileMetadata, mediaContent); -> drive.files().create(fileMetadata, mediaContent)
getTitle() -> getName()
uploadedFile.getDownloadUrl() -> uploadedFile.getWebViewLink()
Following code has all new Method names.
change last part of code and paste
private static File uploadFile(boolean useDirectUpload) throws IOException {
File fileMetadata = new File();
fileMetadata.setName(UPLOAD_FILE.getName());
FileContent mediaContent = new FileContent("image/jpeg", UPLOAD_FILE);

It would be helpful if you could state what error do you see in Imports?
But assuming you are finding errors in Imports it means you are missing project dependencies in your project path. Find the dependencies in Maven POM.xml. If you are not using Maven to build your project, then please download all the dependent JAR files as mentioned in POM.xml
