I/O / Streams :: Java Streaming Big String
Aug 27, 2014I have a very big string that I am returning from servlet to javascript. I am using PrintWriter.
PrintWriter out = response.getWriter();
out.print(bigString);
But as the string is very big my code is not working. My browser just hangs.
Also is it possible to stream the output? i.e instead of sending entire string, can I send small part of string at a time. So that my browser will not hang. I don't want to handle streaming manually I am just looking for an IO class which will do the streaming automatically.

Streaming Audio Files Over Web Using JMF Plugin
Feb 18, 2015I've been experiencing problems with the JMF extension when used in an Applet on the web. The program has worked fine previously but not returns the following error...
PackageManager: error reading registry
javax.media.NoPlayerException: Cannot find a Player for : [filename]

However the program works fine in Eclipse with no errors. I have tried reinstalling the JMF package and setting the CLASSPATH and JMFHOME but it still does not work. I am using the jmf-2_1_1e-alljava version. I have also tried putting the player code in an AccessController.doPrivileged() block but this still does not seem to work.
My code for the player is as follows....
private void play(final String track) {
Thread dispatch = new Thread() {
public void run() {

View Replies View RelatedJavaFX 2.0 :: HTTP Live Streaming M3u8 Example Not Playing
Jul 15, 2014I was testing my JavaFX2.2.7 based media player code in a current Java 6 application when I discovered that HTTP Live Streaming does not seem to work. I can play a local file of the supported format (Sintel trailor mp4 h264) but when I try and use an HTTP Live Stream instead, nothing plays. (for example [URL] ). I end up with a blank player, and no exceptions or errors.
private static final String MEDIA_URL = "http://download.oracle.com/otndocs/products/javafx/JavaRap/prog_index.m3u8";
Media media = new Media(MEDIA_URL);
MediaException ex = media.getError();
if (ex != null){
System.out.println("Media Error" + ex.getMessage());
} else{
System.out.println("No Media Error");
}
Program console output: "No Media Error"
I thought it was something wrong with my player code, so as a last resort, I went to JavaFX 2 - Ensemble and copied the source and put it directly into my application and ran it... Unfortunately the same result occurs. The player runs, but simply shows a blank video window. The controls are available, but no video plays.
Based on the Release notes for Java 2.2.7 I was under the impression that HLS was supported. Am I incorrect?
I cannot upgrade to Java 7 as I am firmly stuck with Java 1.6.0.32 due to project constraints.

I/O / Streams :: How To Iterate Over Files In A Directory One By One
Oct 5, 2014Requirements - Use only standard Java API and no apache file utils for this.
Most of the answers I found on the internet either dont meet this requirement or load all file names into an array which can consume too much memory when no. of files = 20,000+. how I can do this. Is there also a way to keep track of new files that were added during the execution of the loop in this code ?
I/O / Streams :: File Size Comparison
May 20, 2014I would like to create a component to detect the file being modify before process.is it the right way to detect the file modification based on file size value?
Below are the flow:
1. Get the file size of a file
2. Used file size value encrypt it with MD5 algorithm, and say it generated us encrypted value "0123sdf"
3. to avoid user modify the file content, before file process, we take the file and do the encryption with md5 again, if it return value "0123sdf", then we are sure it doesn't have modification.
my question:
a. is it the right approach to detect file modification?
b. what the library advise to use or using java.security.DigestInputStream will do?

View Replies View RelatedI/O / Streams :: Search For A Product In Database
Jun 8, 2014The question is when you send two messages from the client to the server does the server read the messages as one input or do you have to read both inputs on the server side?
Im using DataInputStream and DataOutputStream
On the client side I send two messages one for the database action to be performed and the send is the information needed to get the job done.
Example I want to search for a product in the database.
I send to the server an output message saying search product. I then send to the server which product I want to be searched.
The server then retrieves the message by in.readUTF(); switch statement determines what database action should be performed. Within that case I call another in.readUTF() to pass the information to the database on what product to search for.
Would this work or would the server read both messages from the client as one input stream?
