AEM with google drive API integration
Hi Everyone,
Does anyone have any experience using the google drive API in AEM? I already made and tested the Java code to make the necessary calls to the API but I'm having trouble integrating it with AEM. I already have the google jars as an OSGi bundle and I have the code below to populate and return a list of custom DriveFile Objects.
@Component
@Service(value=DriveManager.class)
public class DriveManager {
static Logger logger = LoggerFactory.getLogger("DriveManager");
private static final String APPLICATION_NAME =
"AEM Drive Manager";
private static final java.io.File DATA_STORE_DIR = new java.io.File(
System.getProperty("user.home"), ".credentials/drive-java-read");
private static FileDataStoreFactory DATA_STORE_FACTORY;
private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
private static final List<String> SCOPES =
Arrays.asList(DriveScopes.DRIVE_METADATA_READONLY);
private static GoogleAuthorizationCodeFlow flow;
static {
try {
DATA_STORE_FACTORY = new FileDataStoreFactory(DATA_STORE_DIR);
} catch (Throwable i) {
logger.error("#############IOException : "+i.getMessage());
}
}
public static Credential authorize() throws IOException {
InputStream in =
DriveManager.class.getResourceAsStream("/client_secret.json");
GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
flow = new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT,
JSON_FACTORY, clientSecrets, SCOPES).setDataStoreFactory(DATA_STORE_FACTORY)
.setAccessType("offline")
.build();
Credential credential = new AuthorizationCodeInstalledApp(
flow, new LocalServerReceiver()).authorize("user");
System.out.println(
"Credentials saved to " + DATA_STORE_DIR.getAbsolutePath());
return credential;
}
public static Drive getDriveService() throws IOException {
Credential credential = authorize();
return new Drive.Builder(
HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName(APPLICATION_NAME)
.build();
}
public List<DriveFile> getFileList(){
logger.info("############# ENTERING GET FILE LIST");
List<DriveFile> driveFileList = new ArrayList<DriveFile>();
try {
Drive service = getDriveService();
FileList results = service.files().list()
.setPageSize(10)
.setFields("nextPageToken, files(id, name)")
.execute();
List<File> files = results.getFiles();
if (files == null || files.size() == 0) {
return driveFileList;
} else {
for (File file : files) {
DriveFile temp = new DriveFile();
temp.setId(file.getId());
temp.setName(file.getName());
temp.setMimeType(file.getMimeType());
driveFileList.add(temp);
}
}
} catch (IOException e) {
logger.error("#############IO Exception when getting File List "+e.toString());
}
for(DriveFile temp : driveFileList){
logger.info("############# FILE " + temp.getName());
}
return driveFileList;
}
}
Unfortunately I am having the following errors below:
08.11.2017 13:03:17.155 *INFO* [0:0:0:0:0:0:0:1 [1510117396763] GET /content/googledrive/en.html HTTP/1.1] DriveManager ############# ENTERING GET FILE LIST

java.lang.NoClassDefFoundError: org/mortbay/component/LifeCycle
It says no ClassDefFoundError for org.mortbay.component but I have found no jars for org.mortbay.component and have already added org.mortbay.jetty core and utilities to my OSGi bundle.
Thank you for your help.
