I/O / Streams :: Java Streaming Big String

Aug 27, 2014

I 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.

Multi-Player Game With Multiple Worlds - Unhandled Packets

Sep 16, 2014

So I am trying to create a Multi-Player game in java, and I have a Game server and a Client. They normally connect with either but I would like to add a login server so that there can be an option to go to a different world then just the main one. It will have the same map and data but will be separate from the Players that are on world one per say. Now if you are on world two I would like it to have the option for you to be able to Private message players that are on World one. That is where the login server comes in to play.

I am still new at Java and would like to be able to understand Packets and how to handle them more clearly. So far I have gotten the basis of the login server connected to the server and the client connects to the server via the login server. But I am getting a bunch of "unhandled packets" and I would like to know how to handle them. Here are some bits of the code.

package com.ls.net;
import org.jboss.netty.channel.ChannelHandlerContext;
import org.jboss.netty.channel.ChannelStateEvent;
import org.jboss.netty.channel.ExceptionEvent;
import org.jboss.netty.channel.MessageEvent;
import org.jboss.netty.channel.SimpleChannelUpstreamHandler;

[Code] ....

So when I run my client this pops up in the console:

[Tue Sep 16 16:50:56 EDT 2014][LoginServer]: Finished initializing login server.
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 15
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 41
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 74

[Code] ....

And here are the class's for Accounts:

package com.ls.net.codec.decoder.packets;
import org.jboss.netty.buffer.ChannelBuffer;
import org.jboss.netty.channel.ChannelHandlerContext;
import com.ls.bufutils.BufferUtils;
import com.ls.net.codec.decoder.PacketDecoder;
import com.ls.net.codec.decoder.handlers.AccountHandler;

[Code] ....

Client And Server Class For UDP Protocol Sending Integer Numbers By Packets

Apr 21, 2014

I have to write a client and server class for a UDP protocol sending integer numbers by UDP packets. So far i have this;

Client Code:

import java.io.*;
import java.net.*;
class UDPClient {
public static void main(String args[]) throws Exception {
BufferedReader inFromUser =
new BufferedReader(new InputStreamReader(System.in));

[Code] ....

But i now need to change this so that:

The client;

1. Reads an integer from keyboard input and stores its value in a UDP packet.
// byte[] send = ByteBuffer.allocate(4).putInt(num).array(); ???

2. Sends the UDP packet to the server, on port number 1999;

3. Listens for UDP packets from the server (until it receives a packet with a non-positive number; see
step (b) below). While listening:

(a) Once it receives a UDP packet from the server, it subtracts 2 from the integer value num contained in it.
// int num = ByteBuffer.wrap(receive).getInt(); ???
(b) Checks the integer value num: if the value is greater than 0 (num>0) then the client stores it in a new UDP packet and sends the packet to the server; otherwise (num<=0) the client terminates.

The Server;

1. Listens on port 1999;

2. For each UDP packet it receives from a client:
(a) extracts the integer value n contained in it;
(b) decreases the value of n by 2;
(c) sends back to the client a UDP packet containing the new value of n.

Streaming Audio Files Over Web Using JMF Plugin

Feb 18, 2015

I'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]
at javax.media.Manager.createPlayerForContent(Manager .java:1412)
at javax.media.Manager.createPlayer(Manager.java:417)

[Code] .....

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() {
try {
if(player!=null)
player.close();

[Code] .....

JavaFX 2.0 :: HTTP Live Streaming M3u8 Example Not Playing

Jul 15, 2014

I 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 need to convert c# function to java method. The important thing is String strKey. Parameters for testing are strMask= 4634958 and strSN=1394901184 and the result must be strKey = 2156325482!!! The result that I am getting with my Java code is 2138641814.This is C# code:

System.UInt32 dwSN, dwMask;

Convert Java Object Using JAXB To XML

Nov 7, 2014

I am suppose to have a method called save() which should marshall the list of computer parts in the right panel to an XML file. In reverse, another method called load() that should unmarshall the saved XML file back into an object. So basically, the Save event will call save() method and save the list of parts in the right panel to an XML file. The Load event should clear the right panel, and call load() method. When load() is called, it should display the unmarshalled data in the right panel. I got "Exit" to work.

I'm having hard time figuring out the "Load" and "Save" parts though.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class PCParts implements ActionListener{
