问题 I am using the Kaltura client library for Android to upload a video. It successfully creates the entry on the server, but when it gets to the point of actually uploading the video file, it fails with Error 413 - Request Entity Too Large. KalturaMediaEntry mediaEntry = new KalturaMediaEntry(); mediaEntry.name = title; mediaEntry.mediaType = KalturaMediaType.VIDEO; mediaEntry = kalturaClient.getMediaService().add(mediaEntry); KalturaUploadToken token = new KalturaUploadToken(); token =

问题 I'm developing an android application that transfers images from one device to another. The received image will be stored in the local database of my application created by help of SQLite. To achieve my goals, I've converted the bitmap into byte[] and transferred it to another device by help of outputStream. I did achieve success from the above implementation but, failed in transferring the second image on the connected device. The problem which I am facing is the following: The first

问题 I'm trying to build an app to detect images which are advertisements from the webpages. Once I detect those I`ll not be allowing those to be displayed on the client side. Basically I'm using Back-propagation algorithm to train the neural network using the dataset given here: http://archive.ics.uci.edu/ml/datasets/Internet+Advertisements. But in that dataset no. of attributes are very high. In fact one of the mentors of the project told me that If you train the Neural Network with that many

问题 I have a Java program that creates a number of xml file and then zips them up and saves them to the file system. Later in the program I want to put that same zip file into a blob column of my oracle database. Problem is I'm not sure how to do that. I don't need to read it or do anything with the data, just move it to the database for persistent, central storage. Thanks! 回答1: There are several ways you can do this, but PreparedStatement.setBinaryStream is probably the best way. public void

问题 Assume a client application that uses a FileSplit object in order to read the actual bytes from the corresponding file. To do so, an InputStream object has to be created from the FileSplit , via code like: FileSplit split = ... // The FileSplit reference FileSystem fs = ... // The HDFS reference FSDataInputStream fsin = fs.open(split.getPath()); long start = split.getStart()-1; // Byte before the first if (start >= 0) { fsin.seek(start); } The adjustment of the stream by -1 is present in some

问题 I am using the Ganymede ssh library (http://www.ganymed.ethz.ch/ssh2/) to connect to a ssh server (obviously ;)). Normally, when using the bash, when a user presses the TAB key on the keyboard a list of possible command completions appears. I want to achieve the same behaviour, but send the tab character manually. Unfortunately I am not aware how to do this. Sending "\t" does not work. Edit: The solution must be a generic which does not only work in bash, but also in other programs, like

问题 Here's the code: package testpack; import java.io.*; public class InputStreamReadDemo { private void readByte() throws IOException { System.out.print("Enter the byte of data that you want to be read: "); int a = System.in.read(); System.out.println("The first byte of data that you inputted corresponds to the binary value "+Integer.toBinaryString(a)+" and to the integer value "+a+"."); // tried writing System.in.close(); and System.in.reset(); } private void readLine() throws IOException {

问题 I was wondering how one would go about importing a text file. I want to import a file and then read it line by line. thanks! 回答1: I've no idea what you mean by "importing" a file, but here's the simplest way to open and read a text file line by line, using just standard Java classes. (This should work for all versions of Java SE back to JDK1.1. Using Scanner is another option for JDK1.5 and later.) BufferedReader br = new BufferedReader( new InputStreamReader(new FileInputStream(fileName)));
