    <p>I'm having some problems while uploading a .txt file with Google Drive API. Here's my code:</p> <pre><code>import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow; import com.google.api.client.googleapis.auth.oauth2.GoogleCredential; import com.google.api.client.googleapis.auth.oauth2.GoogleTokenResponse;

import com.google.api.client.json.jackson.JacksonFactory; import com.google.api.services.drive.Drive; import com.google.api.services.drive.DriveScopes; import com.google.api.services.drive.model.File; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.Arrays; public class DriveCommandLine { private static String CLIENT_ID = "client_id"; private static String CLIENT_SECRET = "client_secret"; private static String REDIRECT_URI = "urn:ietf:wg:oauth:2.0:oob"; public static void main(String[] args) throws IOException { HttpTransport httpTransport = new NetHttpTransport(); JsonFactory jsonFactory = new JacksonFactory(); GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder( httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET, Arrays.asList(DriveScopes.DRIVE)) .setAccessType("online") .setApprovalPrompt("auto").build(); String url = flow.newAuthorizationUrl().setRedirectUri(REDIRECT_URI).build(); System.out.println("Please open the following URL in your browser then type the authorization code:"); System.out.println(" " + url); BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String code = br.readLine(); GoogleTokenResponse response = flow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute(); GoogleCredential credential = new GoogleCredential().setFromTokenResponse(response); //Create a new authorized API client Drive service = new Drive.Builder(httpTransport, jsonFactory, credential).build(); //Insert a file File body = new File(); body.setTitle("Document Example"); body.setDescription("This is a test of Google Drive SDK"); body.setMimeType("text/plain"); java.io.File fileContent = new java.io.File("document.txt"); FileContent mediaContent = new FileContent("text/plain", fileContent); File file = service.files().insert(body, mediaContent).execute(); System.out.println("File ID: " + file.getId()); } } </code></pre> <p>The problem it's in this line:</p> <pre><code>GoogleTokenResponse response = flow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute();

    1. COI'm not familiar with google drive api, but seems like it might complaining about something related to the truststore and certificates. Maybe double check you've created the truststore with appropriate certs? Also take a look at http://stackoverflow.com/questions/6784463/error-trustanchors-parameter-must-be-non-empty

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
