JTree simple problem.
I got a JTree which triggers a popupmenu which each item will act differently according to what is the selected node.
I tried to look on API,but it elusive to me.
Can somebody pot me a code snippet on how to get the currently selected node of a jtree(only one no multiselect allowed).
In delphi its just walk in the park. but I am just new to java park.
And I need to cross it fast :)
myTree.getSelectionPath().getLastPathComponent();

Hello
Simple problem - don,t know how to solve it.
With Premiere CC when I try to do a selection (click... drag... release the click) very often it stop way before the end of the move I'm swinging the Magic Mouse. I taught that the mouse clicking was defective and went to get a new Magic Mouse after lots of frustration. Today, I have an edit to do it it does the SAME thing !!
I was like ????#$%?&*(???
Opened all the lights and taught I've trow the new mouse to the garbage and was using the defective mouse again... no !! - ??
Actually, the bran new mouse is doing the same thing. What I understand after investigating on the motion and watching carefully my fingers !! - is that when I click I have to keep my finger at the EXACT same place on the mouse... drag and release and it's fine. If I click by pushing on the mouse and my finder is moving of a 1/32th of a millimeter, it will release and my selection will be to redo. You can understand my frustration ! - 75$ later... same problem, but I know that if I click with about 5 pounds of pressure and trying to pass my finger through the plastic of the mouse, it you stay steady and make it !
The problem is that scrolling is enable while clicking and it bugs.
How to disable it ??
Simple question - can't find the answer !Helllooo !?
sorry but the Magic Mouse is just useless with the new Adobe Premiere CC and since I'm not the only one but can't find answer this is really disappointing. This mouse is just fantastic and now I have to swap from a USB mouse to the Magic Mouse every times I do some editing. My USB mouse if hurting my hand somehow and I want to got back to the Magic Mouse asap. Please - for sure there is a simple solution !
Thanks !! -
Please a simple problem but I don't know how to solve it. After installing 16 gb of ram all is good but when I turn on the computer it is a window signaling that all is correct. How is possible to delete once and for all that window? Thank you
Well then maybe you could take a screenshot because the appearance of such a window is news to me.
Also post your OS X version and what model Mac you have. The more detail, the better. Thanks.
To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot on your Desktop.
If you can't find it on your Desktop look in your Documents or Downloads folder.
When you post your response, click the "camera" icon above the text field:
This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button.
⌘ Shift 4 and then pressing the space bar captures the frontmost window.
⌘ Shift 3 captures the entire screen.
Drag the screenshot to the Trash after you post your reply. -
Very Simple Problem-- Need help in method selection process
Hello,
It's difficult to explain the background of the program I am making-- but I am stuck at a very simple problem, that I can only solve with a very long block of if statements:
I have 3 possible numbers-- 1, 2, or 3.
Imagine two numbers are already taken-- say 1 and 2. I want a variable to set itself to the number that's not taken (3).
So, again: If two numbers were taken say 2 or 3-- I want the variable to be sent to the other one that isn't taken-- 1.
Thank you for your help,
Evan.Actually, I'll just tell you the context of the program-- here is what I have so far:
This program is meant to simulate Monty Hall Problem:
http://en.wikipedia.org/wiki/Monty_Hall_problem
The program sets up an array of three possible values. Each one of those values represents a door with either a goat or a car behind it. It then randomly sets one of those values to 1 (in order to represent a car as per the Monty Hall problem), and 0's represent goats.
The user, which is simulated by the program (does not involve actual interaction), chooses a door initially.
The game show hosts then reveals a door that is not the users initial choice, but IS a goat ( an array value of 0).
For example if the array was [0][0][1]
The user could pick door one (array position 0). Which is a goat.
The game show host then reveals a goat that is not the users choice-- which would be array position 1.
After the game show host reveals the goat-- I want the user to always switch his decision to the only other remaining door that was not his first choice.
Then I wanted the computer to test to see if his final choice is the one with a car. And to tally up the amount of times he got it right.
--Sorry that was long winded:
import TerminalIO.*;//imports TerminalIO package for system.out.println
import java.util.*;//import java.util for random
public class Monty_Problem
int doors[]= {0,0,0};
Random rand= new Random();
double wins,totals=0;
public void carAssignment()
int car_door= rand.nextInt(3);
doors[car_door]=1;
public int judgesChoice(int judgeDoor, int initialChoice)
if(judgeDoor != initialChoice && doors[judgeDoor]!=1)
return judgeDoor;
else
return judgesChoice(rand.nextInt(3), initialChoice); //infinite loop right here that I cannot remedy. I want the program to have the judge pick a location that is not occupied by a '1' and is not the user's choice.
public void gamePlaySwitches()
int initialChoice= rand.nextInt(3);
int judgeDoor = 0;
int secondChoice= 0;
judgeDoor= judgesChoice(rand.nextInt(3), initialChoice);
//This part is meant to have the user switch choices from his initial choice
// to the only other choice that hasn't been revealed by the judge.
while(secondChoice == initialChoice || secondChoice== judgeDoor)
secondChoice++;
if(doors[secondChoice]==1)
wins++;
totals++;
else
totals++;
public static void main(String [] args)//creates the main menu
Monty_Problem a= new Monty_Problem();
int games=0;
while(games!=100)
a.carAssignment();
a.gamePlaySwitches();
games++;
System.out.println(a.wins/a.totals);

A Simple problem I`m sure BUT ITS DRIViNG ME CRAAAZY!
Hello,
I hope someone can help.
I published a site with the first podcst episode using iweb.It went through onto iTunes bo problem so all`s good... so today I put together the 2nd episode, submit it to itunes as before...up comes the `..please provide the link to the podcast RSS feed ...' etc
Podcast Feed URL:http://rss.mac.com/jubemeg/iWeb/Bandwagon/podcast/rss.xml is the address I`m given as with the first episode, I press continue and ....Unfortunatly THE FEED HAS ALREADY BEEN SUBMITTED.Course it has! Help!
I have looked through the tech specs and I cant make head nor tail of it can someone help me in real basic layman language!
Thank you,
JulesJules, it's a simple problem with a simple fix. (and it drove me nuts too)
Publish to .Mac (or your server if it's different)... then PING itunes to let them know to go look for new content on your server (or .Mac). You PING iTunes by cutting and pasting the url addy below into safari and clicking return. You'll get an error message, don't worry, it's supposed to happen. About an hour later, maybe a bit longer, your new episode will be available.
DONT submit your podcast by selecting the "SUBMIT PODCAST TO ITUNES" menu selection again. That command is for your first submission, not your subsequent ones. Think of your podcast as a book. And each episode is a chapter. When you ping iTunes, they go get the whereabouts of the new chapter and make it available for the world to come and read, hear, or watch.
the PING url is...
https://phobos.apple.com/WebObjects/MZFinance.woa/wa/pingPodcast?id=INSERTYOURFE EDIDHERE
Your feed ID number is in your original email from the itunes folks when they sent you your acceptance email and said that your podcast was now up and running on the ITMS.
Hope this helps.

I am in a great problem with a very simple problem. I am new to J2EE. I had installed j2sdk1.4.0_03 / tomcat 4.1 in windows 2000. my problem is that the servlets are not being compiled. The error is " package javax.servlet is not found". error are also there in all the classes of this packege like in HttpServletResponse, HttpServletRequest etc.
The classpath are correct. One of my friend is working with the same version and with the same classpath but in Windows XP..
can anyone tell me why this is happening. and how to overcome this. PLEASE...............Add the jar that contains the javax.servlet package to your javac classpath using the -classpath option. Not sure why your CLASSPATH isn't working maybe youi have some invalid characters or directories with spaces that aren't quoted etc... I believe the servlet APIs are in servlet-api.jar, or at least they are in 5.0. Also please searxh the forums in the future this is a pretty typical question and has been answered numerous times.

A simple problem to solve... I hope.
$A simple problem to solve... I hope. Hi Guys,
This is my first post on this forum, and I'm hoping that the problem I'm encountering at the moment is down to my own stupidity rather than technical issues.
Firstly, I should mention that I have used my X-fi sound blaster xtreme audio card for months now in my old PC which was running XP 32 bit with no problems whatsoever. In the last day I've built a new PC which has the following specs:
Intel I7 860
tb HDD
4gb Ram
Windows 7 Ultimate 64
Nvidia GTX280
Sound was very quiet and of a fairly poor quality to begin with, and I soon realised that I hadn't installed any drivers for the soundcard, so I went ahead and did so. Following this, I enter a **bleep**storm of illogical proportions which to me makes absolutely no sense.
I get no sound from my speakers or headphones whatsoever. I have a pair of M-Audio AV-40 monitors at the moment, and no matter what I try, I can't get sound to work. When I go to the mixer, it seems odd to me
http://yfrog.com/7fxfiproblemj
I thought that there would be options for Line Outs etc, but I may be wrong.
I've run the diagnostic tests and everything comes back absolutely fine.
The weirdest thing however is the fact that when I test the speaker configuration, it responds to nothing except from the 7. surround sound, and my speakers react to the bottom left and bottom right speakers. I've tried installing, re-installing drivers no end. Looked for fixes and checked google as well and found nothing that matches the description of my problem.
Am I missing out on something really obvious here? Or is there a more technical underlying factor ?behind this issue.
Any help is hugely appreciated, thanks?Thanks for all of you help, but I still don't think the problem's solved.
Here's the problem explained more thouroloy. I have a java program that uses lots of jar files. That means that to run my program, I need to have the CLASSPATH set to pick up all of these jar files. I'd also like to be able to give someone a copy of this program on a cd and have them immediately run it without having to assume anything about their configuration (except that they have java installed).
So what I did was create a batch file that (at least temporarily) sets up the CLASSPATH to meet my needs. It then calls "java myProgram <all the other parms...>".
Things run fine, except that the command window that gets opened up stays around while Swing program runs, and doesn't close until I close the Swing program. I'd like that that didn't happen.
-- echo off
Not going to do anything to help. It will stop the batch commands from echoing, but that's about it.
-- javaw
I tried this and it also doesn't work. It seems that neither java nor javaw return until after the program that it is running actually end.
-- Executable jar
Sounds promising, but will it work? How do I make sure the CLASSPATH is properly set before running this?
Thanks again for all of your hlep.

I loaded Mac OS X v10.7 Lion yesterday. Everything’s running fine, except for a simple problem. Any time I want to copy a file, JPEG, etc., I am prompted “Finder wants to make changes. Type your password to allow this.” I don’t want this!! Is there a way to unlock “Finder” or rid this process?
Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. You can demote it back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:20 ~ $_ ; chmod -R -N ~ $_ 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
resetpassword
That's one word, all lower case, with no spaces. Then press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar. -

Hello, how are you?
I tell her that I'm developing a flash content with as2 and I have a very simple problem, I hope you can help me
I happened to create a movie clip and inside to create a scroll that is two isntancias,
I mean:
in the first frame create a button in the 6 to 5 buttons and an action to melleve the sixth frame and another to return. (Elemental truth)
Now I have a problem. In creating a movie clip instance name to each button and in the average place the next fram as2,
boton.onRollOver name = function () {
gotoAndStop ("Scene 1", "eqtiqueta");
because what I want is that from inside the movie clip, go to the scene proncipal to a frame that is three in the label name.
however, does not work.
appreciate your cooperation.

Hello --
I've searched this subject ad nauseum on these forums and the rest of the web, and I'm still coming up blank.
Basically, I have a file structure JTree. To do a "refresh" view, I basically kill the original object, and rebuild it again -- while first storing the last TreePath the user was on.
Since this tree is built dynamically, placeholders are used to tell if the parent node has any children. From there, it looks up its children.
During the refresh, I fire the tree.expandPath(path), and in my expansion listener, it should take care of the rest.
Well, it seems like all the steps are going correctly, due to the debug output I'm getting, but I can't get the tree to scroll to the path. Here's the reload part:
public void refreshTree(TreePath path){
TP tp = null;
Object [] obj = path.getPath();
for (int i = 2; i <= obj.length; i++){
tp = new TP(obj, i);
tree.expandPath(tp.getTP());
//I've tried these in the for loop to no avail
// tree.setSelectionPath(tp.getTP());
// tree.scrollPathToVisible(tp.getTP());
//this should be the last and final TreePath object
tree.expandPath(tp.getTP());
//tree.getSelectionModel().setSelectionPath(tp.getTP());
tree.setSelectionPath(tp.getTP());
tree.scrollPathToVisible(tp.getTP());
//this class exists so I can build the treepath one
//leaf at a time
class TP extends TreePath{
public TP(Object[] obj, int length){
super(obj, length);
public TreePath getTP(){
return this;
}I've tried rebuild and all, and it seems like everything is doing what it's supposed to except drawing it right. Here's the code for the expansion:
class selectionListener implements TreeExpansionListener{
public void treeExpanded(TreeExpansionEvent evt){
DefaultMutableTreeNode node = getTreeNode(evt.getPath());
TreeNode firstBorn = node.getFirstChild();
if (firstBorn.toString().equals(PLACEHOLDER)){
System.out.println("made it"); //debug
populateTree(evt.getPath()); //this gets the new stuff
public void treeCollapsed(TreeExpansionEvent evt){}
}So, again, it seems like everything is firing the way it should, it's just not redrawing the tree to the current path.
I'm on Java 1.4[02], Windows 2K, and JTree is set to SINGLE selection mode. If you need any additional information, please let me know.
Thank you very much for your time.
-SteveIt seems that the tree is firing a node change itself, because I have code executing in the
public void treeExpanded(TreeExpansionEvent evt)
function.
I also put a bit of debug code in... I have
System.out.println("Is collapsed? " + tree.isCollapsed(tp.getTP()));
Inside my for loop... the output is false everytime.
So it seems that everything exists, it's just not repainting the gui for some reason or other. I'm not spinning off seperate threads to do anything, so I'd assume it's not a thread problem.
Any ideas? This is really getting frustrating, for something I thought would be so simple. -
I've got an application which uses a JTree to display the data and cannot get a screen reader to speak any of the nodes as I navigate to them with the mouse or by the keyboard. I've used javaferret and indeed, it shows that no accessible name or description is getting set as I navigate around. Is this a problem with the JTree itself or a problem with the access bridge? Is there any way for me to diagnose this problem?
I'm using the default cell renderer. I've verified that I can reproduce the problem with simple examples from the tutorials. Here's a bit of code that I'm currently using to reproduce. It turns out that JAWS always reads the node you left rather than the node you were entered....apparently the active descendent isn't being updated properly...

A simple problem with sateful Session beans
Hi,
I have a really novice problem with stateful session bean in Java EE 5.
I have written a simple session bean which has a counter inside it and every time a client call this bean it must increment the count value and return it back.
I have also created a simple servlet to call this session bean.
Everything seemed fine I opened a firefox window and tried to load the page, the counter incremented from 1 to 3 for the 3 times that I reloaded the page then I opened an IE window (which I think is actually a new client) but the page counter started from 4 not 1 for the new client and it means that the new client has access to the old client session bean.
Am I missing anything here???
Isn�t it the way that a stateful session bean must react?
This is my stateful session bean source.
package test;
import javax.ejb.Stateful;
@Stateful
public class SecondSessionBean implements SecondSessionRemote
private int cnt;
/** Creates a new instance of SecondSessionBean */
public SecondSessionBean ()
cnt=1;
public int getCnt()
return cnt++;
And this is my simple client site servlet
package rezaServlets;
import java.io.*;
import java.net.*;
import javax.ejb.EJB;
import javax.servlet.*;
import javax.servlet.http.*;
import test.SecondSessionRemote;
public class main extends HttpServlet
@EJB
private SecondSessionRemote secondSessionBean;
protected void processRequest (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
response.setContentType ("text/html;charset=UTF-8");
PrintWriter out = response.getWriter ();
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet main</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Our count is " + Integer.toString (secondSessionBean.getCnt ()) + "</h1>");
out.println("</body>");
out.println("</html>");
out.close ();
protected void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
processRequest (request, response);
protected void doPost (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
processRequest (request, response);
}You are injecting a reference to a stateful session bean to an instance variable in the servlet. This bean instance is shared by all servlet request, and that's why you are seeing this odd behavior.
You can use type-leve injection for the stateful bean, and then lookup the bean inside your request-processing method. You may also save this bean ref in HttpSession.
@EJB(name="ejb/foo", beanName="SecondBean", beanInterface="com.foo.foo.SecondBeanRemote")
public MyServlet extends HttpServlet {
ic.lookup("java:comp/env/ejb/foo");

A Simple Problem Which Just Can't Be Fixed... Please HELP!
Hi,
I have absolutely no problems in designing up DVD's in DVDSP, mine is a very simple one and happens everytime I design a DVD...
Some have said it's to do with the DVD player settings, but i find that hard to believe because it doesn't happen on DVD's I hire...
The problem is this. Whenever "STOP" is pushed while my DVD is sitting on the "Main Menu", no matter how many times stop is pressed if play is pressed again it automatically starts to play the first track... This happens with all the DVD's i create. If the player is turned off and on it goes back to the menu and everything works fine... Surely there must be a way to fix this? It does't happen on DVD's I hire...
Any ideas would be fantastic,
Thanks,
TomHi Tom
The old Stop-Stop-Play technique is a bit of a shortcut to the main content of a DVD depending on how its authored - and it seems to work on some DVD players and not others.
Basically, what ever track is listed as Track 1 in your DVDSP outline view will be the target of this technique. The way to prevent it from happening is to make Track 1 a 1 sec video of black with all the UOPs disabled that end jumps to your main menu. That way if the viewer tries to short cut to your content they are taken straight back to the menu without passing GO.
Hope that helps
Cheers
