    <p>With the help of using the Google document <a href="https://developers.google.com/appengine/docs/java/blobstore/overview#Writing_Files_to_the_Blobstore" rel="nofollow">Writing files to a blob store</a></p> <p>I can store the file in Google Cloud in below way,</p> <pre><code> //My servlet Class private StorageService storage = new StorageService(); FileService fileService = FileServiceFactory.getFileService(); AppEngineFile file = fileService.createNewBlobFile(mime, fileName); boolean lock = true; FileWriteChannel writeChannel = fileService.openWriteChannel(file, lock); byte[] b1 = new byte[BUFFER_SIZE]; int readBytes1; storage.init(fileName, mime); // Calling my Java Class Here while ((readBytes1 = is1.read(b1)) != -1) { writeChannel.write(ByteBuffer.wrap(b1, 0, readBytes1)); storage.storeFile(b1, readBytes1);} writeChannel.closeFinally(); </code></pre> <p>I have a storage java class to store the data in Google cloud that is below here,</p> <pre><code>//My Storage Class public class StorageService { public static final String BUCKET_NAME = "MyBucket"; public void init(String fileName, String mime) throws Exception { GSFileOptionsBuilder builder = new GSFileOptionsBuilder().setAcl("public_read").setBucket(BUCKET_NAME).setKey(fileName).setMimeType(mime); AppEngineFile writableFile = fileService.createNewGSFile(builder.build()); boolean lock = true; writeChannel = fileService.openWriteChannel(writableFile, lock); bos = new BufferedOutputStream(Channels.newOutputStream(writeChannel)); public void storeFile(byte[] b, int readSize) throws Exception { bos.write(b,0,readSize); bos.flush(); }} </code></pre> <p>From the above reference i can store the file directly in Google cloud. But i need to store those files as blob values using the File service. </p> <p>Can anyone suggest me an idea.</p> <p>your help will be appreciated.</p>

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.
