Is code in ParserCallback executed in a different thread?
Hello everybody,
I have a question regarding the javax.swing.text.html.HTMLEditorKit.ParserCallback class. I 've read that parsing an HTML page using HTMLEditorKit.Parser.parse() isn't taking place in the same thread as the code in the HTMLEditorKit.ParserCallback class (of course, in my case, a subclass). Therefore I shouldn't assume that the HTML page is completely parsed when HTMLEditorKit.Parser.parse() returns. Can anyone confirm this?
I did read the source, but to me it seems that parsing and callback is taking place in the same thread :-|
Thanks,
KeRMiT1281
My Vote is no, altho since this parser is replaceable, perhaps others are free to do that. But here's a test with the default one.
import javax.swing.text.*;
import javax.swing.text.html.*;
import java.io.*;
public class HTMLParserTest
static class MyKit extends HTMLEditorKit
public HTMLEditorKit.Parser cheat()
return getParser();
public static void main(String[] args)
try
MyKit kit = new MyKit();
HTMLEditorKit.Parser p = kit.cheat();
StringReader sr = new StringReader("<html><body><a href='foo'>bar</a></body></html>");
HTMLEditorKit.ParserCallback cb = new HTMLEditorKit.ParserCallback()
public void handleStartTag( HTML.Tag t, MutableAttributeSet a, int pos )
System.out.println( "Callbacks thread " + Thread.currentThread().toString());
System.out.println( "Main thread " + Thread.currentThread().toString());
p.parse(sr, cb, true);
catch (Exception e)
e.printStackTrace();
}

Different execute queues with different thread priorities
We are running WebLogic 6.1, SP2 on Solaris 2.8 and I have a question related to the
use of Execute queues
I'm aware that the administration console servlets, and the rest of requests given
to the server run in separate execution queues each with their own pool of threads.
There is an <executequeue> element in the config.xml that allows you to change the
parameters of the default execute queue that most requests are handled in.
My question is is it possible to create new execute queues, each with a given number
of threads running at a different priority. Then one could assign a particular WAR
deployment to a queue and hence control the priority that certain requests run at
governed by the deployment that received the initial request.
Essentially the problem that I'm trying to address is that I have a JAR with MDBs
in it. I also have JARs with Entity and Session EJBs and WARs. They are all using
the same pool of threads to execute. I want to be able to throttle the MDBs as they
receive messages so they don't take over the machine and interfere with interactive
use. Now I can limit the number of MDBs in the MDB pool, but then if the machine
is not being used by users, then the machine resources are wasted only allowing one
MDB to be active at a time when there are a lot of messages in the queue.
What I want to be able to do is to have as many MDBs run as I can, up to a certain
limit, say 15 for example, but not to pull from the same thread pool/execute queue
as the requests for URLs in the WAR. Also I want the MDB threads to run at a much
lower priority and always give preference to interactive requests.
So interactive threads will always win and grab the processors if interactive use
is high, but if it's not, the MDBs can run instead.
Regs,
PaulHi,
I had a chat with BEA support about my issue. You can create multiple ExecuteQueues
and assign them to servlet definitions in WARs in the web.xml, and with an option
to the EJBC compiler, you can assign a particular class of EJB to an ExecuteQeueue.
For details see http://e-docs.bea.com/wls/docs61/perform/AppTuning.html#1106284
Presumably it's the thread of the initial request that counts, i.e. if a WAR calls
an EJB, then it's the thread in the execute queue of the WAR that will be used right
the way through the request, not that of the EJB being called, assuming they are
both deployed in the same WebLogic instance. If they were in different instances,
you would obviously have a thread from the WAR queue on one instance, and a thread
from the EJB queue on another instance.
If a plain Java command-line client connected directly to an EJB, then it would be
the thread from the ExecuteQueue of the EJB that would get used.
I've been told that MDBs always run in the default queue, so it seems that the way
for me to do what I want is just to create an ExecuteQueue, set the priority of the
threads in this queue to be higher than that of the default queue, and assign this
queue to my WARs. I can leave my EJBs running in the default queue.

Run sql query on a different thread
Hello,
I have a swing app that queries an MS SQL database and it works fine and everything happens in the same thread. However for improved performance and to avoid freeze ups, I want the SQL queries themselves to execute on a different thread as a different class, other than the swing app class. The query results (Result Set) I want them back to my swing app so I can present them on a JTable.
Here is an example of what I am trying to accomplish:
- Press button in my swing app.
- Call class that implements Runnable
- In the Run method of the new class do the following (this code will execute in a new thread):
url = "jdbc:sqlserver://ServerName:1433;databaseName=Database;user=UserName;password=password";
try{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con = DriverManager.getConnection(url);
Statement stmt;
ResultSet rs;
stmt = con.createStatement();
String queryString = "select * from databaseName";
rs = stmt.executeQuery(queryString);
con.close();
catch(Exception em){
em.printStackTrace();
JOptionPane.showMessageDialog(null,em.toString());
}- Get the ResultSet rs back from the class
- Work with the results back in my swing app and present them in the JTable
while(rs.next()){
//do some stuff
}Any help or hints are greatly appreciated.
Thanks,
ChrisTwo suggestions:
-- Take a look at SwingWorker for taking care of the threading issues
-- Keep all database handling code together. Collect the records into a Collection -- most likely ArrayList -- and return that. This way you can close the Connection and RecordSet within the same method that opens them.

For example, I want to set up a pdf embeded with code, and send it on-line. People who want it should pay for it first and get the access code. I need to set different access code in order to avoid people A give the access to people B.
Unless you use a very expensive DRM protection measure, I don't see how it's possible. How can you prevent someone from sending a file with the password to someone else?

public ch06_03()Since you didn't use code-formatting tags ([ code ] and [ /code ] without the spaces) it's kinda hard to look at it. But I'm sure it DID execute much more than just the return statement - maybe you're not closing a file or db connection, or maybe you're seeing a cached page, so it actually isn't executing ANYTHING on the server (is your browser set to never check for newer pages so it (almost) always returns from cache, for example?)

What does this mean and how do I fix it? Error ITMS-9000 "Invalid Code Signing The executable ´viwer.app/ viewer´ must be signed with the certificate that is contained in the provisioning profile"
If you had Firefox save your Yahoo password, first try deleting that here:
orange Firefox button ''or'' classic Tools menu > Options > Security > "Saved Passwords"
The "signed out" message seems to be related to how Yahoo authenticates you. Some users have reported that disabling automatic proxy detection solves the problem, and it also resolves an issue of getting logged out every few minutes, if you have ever experienced that.
To make the change:
orange Firefox button ''or'' classic Tools menu > Options > Advanced
On the "Network" mini-tab, click the "Settings" button, then choose "No Proxy" and OK your way back out.
If your work connection requires you to use a proxy server, try the "Use system settings" option instead.
Does that help? -

Invoking method on different thread
Hi
I'm developing an addin a application. The addin runs on the main thread. However I need to perform some blocking system calls, which can't be called from the main thread, since it also blocks the application. Therefore, I have a worker thread which performs the blocking call. When the blocking call returns, I need to invoke a method on the main thread. The method must be executed by the main thread, because the method uses some of the applications api functions. If these api functions are called from any other thread than the main thread, the application will crash.
My problem is that I dont know how to invoke a method on a different thread. I guess I need to do the same thing as the SWING package, where gui components should be modified from the event dispatcher thread.
Simplyfied, my code looks something like this:
public class Main
public static void main(String[] args)
Main m = new Main();
m.Test();
public void Test()
//runs on main thread here
//start a new thread which blocks while waiting for user input (simulate my service)
ThreadClass tc = new ThreadClass();
new Thread(tc).start();
while (true)
//perform normal work on gui thread
Thread.yield();
public void MethodNeedsToRunOnMainThread(int c)
//Do something on main thread here
public class ThreadClass implements Runnable
public void run()
ThreadFunction();
public void ThreadFunction()
int c = System.in.read(); //blocking call
//Invoke method on main thread here!
MethodNeedsToRunOnMainThread(int c);
}Hope some of you might point me in the rigth direction!
\Bjarnepdm wrote:
Using a BlockingQueue, the main thread will block while waiting for something to be put in the queue by the worker thread. This will block the program in which my add-in runs, since the main thread is responsible for gui updates etc. Therefore, this is not an option.
Maybe it is simply not possible to what I need.
\Bjarnedepending on what kind of responsiveness you need, you could make your add-in periodically check for these events. call poll() instead of take(), and then continue on with your add-in if poll() returns nothing. the frequency with which your code polls the queue will determine the lag between queueing from the other thread and executing on the main thread. -
Running the TSQCallback function in a different thread?
Hi,
I am looking at the example code directPtrAccess.c where the TSQcallback function is set to be executed in the same thread that generates the data. However, in application, I would like to run the call back function in a separate thread.
I would greatly appreciate if some one can clarify whether this is possible and if yes how it should be done?
Thanks!
SripadIn that example the TSQ callback is not executed in the generation thread: it is executed in the main thread instead.
The generation thread is unknown (the thread ID is not saved in any variable) but is it different from the main thread, which is the one that handles the user interface.
As you can see, the TSQ callbacl is installed receiving CmtGetCurrentThreadID() in Callback Thread ID; that is to say, it receives the ID of the main thread and executes there.This is a very common situation, where generation / acquisition of data and other tasks are executed in a separate thread and presentation of data and UI handling are executed in the main thread.
If you had previously created a different thread and saved its ID, you could pass it in this parameter and obtain the callback to run in that thread.
Proud to use LW/CVI from 3.1 on.

Problem using a GUI, a loop and a different thread for the loop
Hi everyone!
First of all sorry if my post is in the wrong forum.
I'm designing a client-server project to allow users to comunicate with each other, and I have a problem in the client class. I'm using the UDP transport protocol, and I'm not allowed to use TCP. The thing is, each client is allowed to send and receive a message at any time, so by pushing a button the "sending event" triggers and sends it, and in order to receive i've launched a receiving process in another different thread, so the sending procces wouldn't be blocked.
This is the code of the client class, called Conversacion:
package mymessenger;
import javax.swing.*;
import java.net.*;
import java.io.*;
import java.lang.*;
import java.awt.*;
import java.util.*;
public class Conversacion extends javax.swing.JFrame {
private InetAddress MaquinaServidor;
private int PuertoServidor;
private DatagramSocket MiSocket;
private DatagramPacket PaqueteSalida;
byte [] BufferEntrada= new byte[1024];
private DatagramPacket PaqueteEntrada= new DatagramPacket (BufferEntrada,BufferEntrada.length);
byte [] BufferSalida;
int ack=0;
int puerto_contrario;
String direccion="192.168.1.102";
String direccion_contraria;
String destinatario_completo="";
String nombre_destinatario="";
String nombre_local="";
String mensaje_recibido=""; // This is the variable I want to use every time a client receives a message
boolean salir=false;
public Conversacion()
initComponents();
esperar();
@SuppressWarnings("unchecked")
// Here would come the generated code by Netbeans, which is not relevant in this case
private void enviarActionPerformed(java.awt.event.ActionEvent evt) {
// This is the sending event that calls a function to send the message to the server, i'll post it in another message
void enviar (String mens)
// Function used to send the message to the server, i'll post it in another message
void esperar() // Here's the problem (I think)
new Thread(new Runnable() // I launch it in a new thread, so I don't block "enviar"
public void run() // At first, the client sends some message to the server, so the server knows some data of the client. Go to the while() command please
String respuesta="";
try
MiSocket= new DatagramSocket();
MaquinaServidor= InetAddress.getByName(direccion);
PuertoServidor=7777;
String comando="ENVIAME LOS DATOS AQUI, A LA CONVERSACION";
byte[] na={(byte)(ack%2)};
comando= (new String (na))+comando;
BufferSalida = comando.getBytes();
PaqueteSalida = new DatagramPacket(BufferSalida,BufferSalida.length,MaquinaServidor,PuertoServidor);
segsend(PaqueteSalida);
ack++;
System.out.println("Estoy esperando un mensaje del servidor");
segreceive(PaqueteEntrada);
String retorno = new String(BufferEntrada, 1,PaqueteEntrada.getLength()-1);
int pos= retorno.indexOf("(");
int pos2=retorno.indexOf("]");
int pos3=retorno.indexOf("Ð");
nombre_destinatario=retorno.substring(0,pos-1);
destinatario_completo=retorno.substring(0,pos2+1);
direccion_contraria=retorno.substring(pos2+1,pos3);
nombre_local=retorno.substring(pos3+1);
setTitle(destinatario_completo+" - CONVERSACIÓN");
segreceive(PaqueteEntrada);
respuesta = new String(BufferEntrada, 1,PaqueteEntrada.getLength()-1);
puerto_contrario = Integer.parseInt(respuesta);
while (!salir) // Here begins the infinite loop I use to receive messages over and over again
segreceive(PaqueteEntrada); // I use segreceive that is kind of the same as "receive". No big deal about this
mensaje_recibido = new String(BufferEntrada, 1,PaqueteEntrada.getLength()-1); // Every time a client receives a message, I want to store it in the variable "mensaje_recibido"
int pos4 = mensaje_recibido.indexOf(":"); // This next 4 commands are not relevant
String auxiliar=mensaje_recibido.substring(pos4+2);
if (auxiliar.equals("FINALIZAR CONVERSACION"))
setVisible(false);
SwingUtilities.invokeLater(new Runnable() // Now I want to asign the value of mensaje_recibido (the message I just received) into texto_total, a Swing text area
public void run()
String auxi=texto_total.getText();
if (auxi.equals(""))
texto_total.setText(mensaje_recibido); // if the text area was empty, then then i put into it the message
else
texto_total.setText(auxi+"\n"+mensaje_recibido); // if it's not, then i put the message in the next line of the text area
Thread.sleep(1000);
catch (Exception e3)
System.out.println(e3);
}).start();
}The communication starts and one user is able to send all the messages he wants to the other one, but when the other wants to send one to the first user, the first user receives a message with the same character over and over again that looks like an square ■. Again, this problem comes when a user that already sended a message, and wants to receive one for the first time (and next times). I searched in these forums all day and so far I couldn't fix it.
This problem happens in the receiver client, not in the sender client and not in the server. I already looked into that and those things are doing what they have to. I would be really really grateful if somebody could tell me which is the problem or how to fix this, because I'm becoming nuts.
Now I'm going to post the function "enviar" which sends the message, and the content of "enviarActionPerformed" which calls "enviar".
Again, excuse me if this is the wrong forum for this question. and sorry for my English too.This is the rest of the code, though I don't think the problem is here, maybe by pushing the sending button it causes the receiving problem:
private void enviarActionPerformed(java.awt.event.ActionEvent evt) {
String mensaje=texto.getText();
mensaje=nombre_local+" dice: "+mensaje;
texto.setText("");
String auxiliar=texto_total.getText();
if (auxiliar.equals(""))
texto_total.setText(mensaje);
else
texto_total.setText(auxiliar+"\n"+mensaje);
enviar(mensaje);
