Dumping a huge application in the lap of a stranger and asking them to tell you how to multithread it is a pretty tall order, don't you think? You might try familiarizing yourself with threading concepts here , identifying the parts of your program that you want to split into new threads, and then come back if you have some specific questions.not to mention it sounds like threading is not what the OP even wants
a simple counter would suffice and every time the counter reaches 100 you could print or whatever and then reset the counter

How I can create a XML file from java Aplication

How I can create a XML file from java Aplication
whith have a the following structure
<users>
<user>
<login>anyName</login>
<password>xxxx</password>
</user>
</users>
the password label must be encripted
accept any suggestion

Let us assume you have all the data from the jsp form in an java bean object..
Now you want a xml file. This can be acheived in 2 ways
1. Write it into a file using java.io classes. Say you have a class with name
write("<name>"+obj.getName+</name>);
bingo you have a flat file with the xml
2. Use data binding to do the trick
will recommend JiBx and Castor for the 2nd option

How to set proxy authentication using java properties at run time

Hi All,
How to set proxy authentication using java properties on the command line, or in Netbeans (Project => Properties

         is = u.openStream();         // throws an IOException
         dis = new DataInputStream(new BufferedInputStream(is));
         BufferedReader br = new BufferedReader(new InputStreamReader(dis));
      String strLine;
      //Read File Line By Line
      while ((strLine = br.readLine()) != null)      {
      // Print the content on the console
          System.out.println (strLine);

How to install Java3d into netbeans 6.5

I recently downloaded the Java 3D file : j3d-1_5_2-xxxxxx but I don't really know how to "install" it. I looked and found a thing on how to insall it on netbeans but the place they are telling me to go to doesn't exist. I am using netbeans 6.5 and supposedly you are supposed to install the J3D.nbm or something into netbeans but i can't find that inside of my downloaded folder. Is there something I did wrong i.e. downloaded the wrong thing, are looking in the wrong place, are missing somthing please tell me.
Thanks
Thimbletack

Just posting an update. I found that a place that says you need to go here to download the module for netbeans to install it:
http://java3d.netbeans.org/
but that doesn't reallys show how to install java 3d or anything, it doesn't even have a download button for the module. I got that information here:
http://java3d.j3d.org/faq/editors.html
but i really just don't know how to install this thing. Can anyone help?

How to implement route cipher using java?

Hi guys,,,
I really got a headache solving how to implement route cipher using java lang,,i already got the concept but i really dont get how to implement it using java actually i want to make a presentation of how route cipher works using "adobe flash" but first i will implement it using java coz flash actionscripts are closer to java lang.
Hope you could post some examples or ideas...i would really appreciate it!
thank you so much...

just add an action listener (either keypressed or keytyped) to the frame that you want to record. I did this in NetBeans in about 2 seconds. I can simplify it if you need. As for loging it just write the characters to a file output stream.
public class test extends javax.swing.JFrame {
    /** Creates new form test */
    public test() {
        initComponents();
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
    // <editor-fold defaultstate="collapsed" desc=" Generated Code ">
    private void initComponents() {

            public void keyTyped(java.awt.event.KeyEvent evt) {
                formKeyTyped(evt);
        pack();
    // </editor-fold>
    private void formKeyTyped(java.awt.event.KeyEvent evt) {

How to compile and register a Java CFX tag with multiple class files?

All-
If this is the wrong forum for CFX questions, please let me
know.
I need to determine how to compile and register a Java CFX
tag that contains multiple class files. One class file implements
the CustomTag interface and the other class files implement various
supporting classes. All of the documentation that I have found
talks about using a single class file. I am assuming that a JAR
file will be involved, but I am not sure of the specifics.
Thanks in advance for your help.
-Josh

Yes, it will involve a jar. Use your java IDE (eclipse,
etcetera ..) to create a jar containing all of the classes. Check
your ide's documentation for how to create jar files. After you
have created the jar, place the jar in the CF class path so CF will
recognize it. For example the {cf_root}/WEB-INF/lib directory. CF
must be restarted before it will detect the new jar. After
restarting CF, register the CFX tag in the ColdFusion Administrator
using the name of the class that implements the CustomTag
interface.
Though it is worth noting you can also instantiate java
classes directly from ColdFusion (ie without using a CFX
tag).
