Swing/AWT/SWT :: Program That Record And Rerun Network Traffic
Sep 21, 2014
I have a program that records and reruns network traffic. It was developed in C and runs in my case under Windows 7 Professional but will run almost anywhere. I have observed a lack of stability.
First I have a JAVA stand alone GUI program that runs the program as follows:
g11_bttn_start_script_capture.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
URI uri = null;
URL url = null;
String tempstr = "";
tempstr = "-s " + g11_txt_PATH_portnumber.getText() + " " + g11_txt_scriptname.getText() + ".both";
[Code] ....
Basically it launches the executable t3drive, hangs arounf so it gets a chance to start, and then connect to it via the embedded browser.
It frequently works, sometimes launches in the browser but then freezes, and sometimes fails to start at all.
t3drive works 100% of the time if I run it under cygwin and I can reliably connect to it using any browser.
Why this might not be stable? Just looking for a direction of what to try next.

I want an app that I can use to save the name, address, item sold, subject discussed and date that I visited someone - in a job similar to a sales rep. I would like to be able to choose how to sort the info so that if I sort by date I can see who hasn't been visited for the longest and start there. If I think of someone's name then of course I want to sort by name.
One of my friends says he works with "php"[? I'm still learning these terms] and everything happens online. I would like it to be an android app so it can be done without an internet connection ....

I can't finish my project in my OOP subject,Ordering System Program,but i am finished with the layout and some processes.
I have complication in which i don't know how to code a process that will record all the ordered items.
i have items like [MS1]Taro Milk Tea.. and there's this textbox that will will get the inputted text and get the quantity of it by JOptionPane.
There's this another JOptionPane that will show the order(s) when "Show Order" button is clicked.
My main problem is i can't record additional items if i want to add more . and my variables are all stored in an array.
Any different way of getting the order,quantity,price of it and Sum all of it and Display the Ordered items...
My professor required that we used inheritance so i have 2 subclasses..
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MilkteaGUI extends JFrame implements ActionListener,WindowListener {
MtGUIProcess mg = new MtGUIProcess();
Label cardNo = new Label("Card Number:");

I am trying to develop an application which will be showing a TimeSeries graph(related library JFreeChart) displaying network activity related to a particular network interface embedded in a JFrame.I have created a JPopUpMenu which is having containing a list of JMenuItems showing network interfaces as their String values.Menu is popping up correctly
Further I am selecting a JMenuItem related to a particular network interface to show network activity in TimeSeries graph.On selecting a JMenuItem I can see that graph is moving on constantly but not able to see any network activity.
Pasted the code below :
package com.ankit.analyser;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.EventQueue;
import java.awt.FlowLayout;
import java.awt.Window;
import javax.swing.JFrame;
[Code] .....
Further I can see that packetArrived method of PacketListener is not being overridden by class PacketHandler as I am not able to see data packets on console and static list in main class is also empty.

I am writing a simple program to simulate a traffic light. What I want is to make them glow after each 1 second, one by one. For example: Firstly Red, then after 10 seconds, red will be put to off and yellow will start glowing and then accordingly green. This process shall continue incessantly (Just for experimental purpose). I have some arrangement done but could not figure out how to put them together in run() method of Runnable interface. I know how interthread communication works. But could not find any logic in this case when three threads will run together.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TrafficLight extends JFrame implements Runnable
{
JButton red, green, yellow ;
TrafficLight()

If I have a web page with a lot of data to show, say a lot of tables and graphics, would using non JSP based frameworks result in a lot more individual AJAX requests? For example if the page have 5 tables, with JSP the whole page will be returned to the browser with data for all 5 tables already. But if this is a pure HTML / Javascript based view, then we need to have each of the 5 tables to make individual AJAX requests in order to render the page. Is this indeed the down side for not using JSP?
The reason I'm asking is because I'm considering moving away from JSP to a template based framework such as Thymeleaf or Freemarker.

I have a java application which uses Google Maps to analyze the traffic condition. But sometimes it can be run and work properly, sometimes not. On some computers on which there is installed java, the program can be run, and on some, again with installed java (jre), exactly the same version, the program can not be run. For example the application first run well on my desktop computer, connected in a LAN, and then stopped working well when run. But when I use laptop which uses the WiFi and run the same computer using VMWare, if I connect to the desktop on which the program can not be run, on the laptop the same program can be run well, in the same room, but using the Wifi.

So I have two related tables - Country (Master) Projects (Detail). Country has a OneToMany relationship with Projects. I put a link on my AllProjects.xhtml page. When tyhe link is clicked it uses a data model class to to display the current (clicked) project record (projectRecord object). After editing all the details, the UPDATE button calls a merge method in the DAO class. On the first attempt to update, nothing happens and the record is returned as it is with no errors. If I try updating again, I get:
Error Code: 1062
Call: INSERT INTO projects_beta2b_projects_beta2b (projects_PROJECTID) VALUES (?)
bind => [1 parameter bound]
Query: DataModifyQuery(name="projects" sql="INSERT INTO projects_beta2b_projects_beta2b (projects_PROJECTID) VALUES (?)")
[Code] .....
My classes are:
projects.java
@Entity
@Table(name = "projects_beta2b")
public class Projects implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int projectid;
private String projectName;
private String client;
[Code] ...
Is the 'new' keyword in the entity class causing the Inser statement in the DAO because the JPA thinks I want to create a new object therefore invokes INSERT instead of UPDATE?

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String delete = ("DELETE FROM anagrafica WHERE Nome = ? And Cognome = ?");
ConnectionManager cm = new ConnectionManager();
String Nome = request.getParameter("nome");
String Cognome = request.getParameter("cognome");
[code]....
and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.

I have a sqlite database i already have the connection with java and it works ... I have a method to add a record ...
public boolean AddRecord(CustomerRecord r){
String sql = "INSERT INTO CustomerRecord (Name, Number, Adress)"
+" VALUES(?,?,?)";
try {Connection connection = getConnection(); // call connection method
connection.setAutoCommit(false);
[Code] .....
I call this method in my interface and i write
if (addrecord == true){System.out.printnl("record added");}
I close the interface then enter search for the record i just added using add record method but i do not find it
what i am trying to say the added record using my application is not there. The question is how to save this record in the database ...
I thought
ps.executeUpdate();
should do this but it is not saved.

In my java web jsf seam jboss application, I want to add a row in a table with some data fields such as date type, String etc, but one field will be a word attachment, how to do it?
Basically, there is a loop to create some rows of data in a table, before each table row data creation, I will create a word file and saved to a local path(the physical file path is hardcoded), then I will create a table row and attach this word file to that row. the loop will continue until the end of loop.

I'm making a game to teach myself programming java so I can start making android. I have this game I'm making where there will be objects(so far its asteroids) will be falling with a progressive velocity (they will move faster as time goes on). The object is the click on the objects before they hit the bottom. It's still early meaning not all the parts I want to implement are there but it works the way I want it to so far besides my click function.
I'm using the Mouse.isButtonDown(0) to record left click but It lets me hold it down and hover over them instead of clicking on each one. Here is a snippet of the part of the code im talking about :
I uploaded a .jar and a exe file so you can see what I mean
[URL] .... -jar
[URL] .... -exe
public void update(GameContainer gc, int d) throws SlickException
{
posX = Mouse.getX();
posY = (Mouse.getY()-height)*-1;
timePassed += d;
deltaTime= deltaTime();

I want to make a service like Spotify, where I can stream music that I have stored on my computer (in this case server) to my laptop or phone.
* What would be a suitable format for this?
* How would I actually stream it? I want to stream, not download and then play, I want to play the music while downloading.
