View Replies View RelatedJava For Data Carving - How To Read Any Of Known Digital Forensics Image
Sep 26, 2014I am looking to do it on data carving which is a technique used in digital forensics to extract known file information from unstructered raw data.
So, Lets say I make a bit for bit image of a usb drive that has some deleted images on it, jpeg maybe.
I can still recover this file by locating its header and footer information as its raw data is still on the drive after it has been deleted.
I would like to build a java application to automate this task. My problem is I dont know how to read any of the known digital forensics image (bit for bit copy of the driv) formats such as aff, e01 or raw dd.
Is it possible for me to read bytes from a raw data file in java, maybe search that file for the bytes I need and pull them out of there, perhaps to an array or something ??
I was thinking, if I could get all the raw data into a binary file in java it might be easier to work from there. What I really need is to get access to those bytes. If I could even write them all out to a text file, Id have something to work with.
Digital Signage System
Jul 1, 2014I am going to try and write a server-client based system.The server will be the design of what I want (e.g: daily advertisements that will be displayed on big monitors connected to the client, with like a slideshow looping). The client will just be receiving information from the server and not doing anything with it except displaying it and perhaps a networking element of the client reporting back to the server if the connection is dropped etc. The administrator can use the server to change the look of the advertisement.
I need the server to PUSH OUT to the client computers.I am on a networking degree so there has to be some elements to networking connections going on and programming is not my strong point. Would I write the server and clients in Java or another program? Will there need to be a "middle" program such as a web server?

Swing/AWT/SWT :: Popup Menu Will Become Invisible Does Not Capture Selected Value / Item

Swing/AWT/SWT :: How To Make One Auto-increment MySQL Table Column Invisible
Dec 8, 2014The problem is that I populate the table with autoincrement primary key. I don't want it to be visible. I have been googling for hours to find no solution. It seems that sql/mysql provides no solution by selecting all table columns except one. So I wonder, how I could overcome this problem. Here is some of my code:
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int col = e.getColumn();
model = (MyTableModel) e.getSource();
String stulpPav = model.getColumnName(col);
Object data = model.getValueAt(row, col);
[Code] .....
The ID is used in
stmt.addBatch("update finance.fin set " + stulpPav + " = " + duom
+ " where ID = " + studId + ";");
I tried to omit ID from my SELECT statement, I tried to put Date as a first element in data[iEil][0] but neither options were successful. Data hasn't been changed in database. NOW, everything works fine, except I don't want ID column to be visible in my table.

View Replies View RelatedCan Use Java Code From OpenScript Or APIs In Separate Java Program?
Oct 24, 2014I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,

Java Application With Several Classes All In Same Java File
Apr 9, 2015I've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
javac -d . File1.java File2.java File3.java (etc...)
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src

I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)

Using Java For Web
Dec 4, 2014I know about coding in general, Java, C, Python, SQL etc. but I barely know anything about making code come together on the web. I have a vague idea about what things like libraries and frameworks are,I'm interested in making a web application with which relies on Java do to the data processing. The idea is that the user inputs some messages, clicks submit, the text is taken away and processed, and the results are displayed on the screen. I would like the UI to be smooth with a modern look and feel.
Also, I usually do programming on Windows but I could also use Linux, so if I'll come across any specific drawbacks using Windows.

Using JFrame In Java?
Apr 16, 2014how to use JFrames and button and so on in Java. I found this video on youtube and followed it along, however even though my program is virtually identical to his, I'm still getting errors.
Here's the video I was watching: Video
And here's my code:
import javax.swing.*; //Imports JFrame and JButton for use
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.*;
import java.awt.*;
import java.awt.event.*;
public class swing
[code]....
The reason why I'm importing some many things is I'm trying everything to try fix my problem.
He's the error messages I'm getting:
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);
[code]....
I used to make the button just create another frame without additional labels but I changed it to be even more similar to his program just to rule everything out. Also initially my program varied quite a bit, I've changed everything to be like his. Even without the ";" error I got, I kept telling me I was not allowed have my class as static, even though the guy in the video has it set to static. Also I don't think my "setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);" is working as it doesn't change color.
I think the problem is with my panel, it isn't adding to the frame for some reason.I'm using TextPad7 and I'm using Win8.
C:UsersWindows 8Documentsswing.java:42: error: '(' or '[' expected
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);
[code]....
I would also like to point out that some of the comments are out of date and are referencing the way the program was before I made it just like his. For example I know my second class isn't inheriting the first class.
