Help need in Signed Applets.....Urgent

Hi,
I am stuck with a problem. Please help me out.
The requirement is :
I have an applet which has to run an executable which produces a .txt. The applet should use this .txt to produce its output.
I made the applet into a signed jar and ran the executable to produce the .txt . But the .txt is outside the jar file and I am not able to use it to create the result.
How do I use the .txt now?? Is the method that I am trying proper or should I use some other method?
Another doubt is, when I run the .html of the applet code (which is in the server), is it cached in the client???

I made the applet into a signed jar and ran the
executable to produce the .txt . But the .txt is
outside the jar file and I am not able to use it to
create the result.
How do I use the .txt now??Hand the user a JFileChooser and let him tell you where the file is, or loook at the exe to see whether you can specify an output directory as a parameter.
Is the method that I am
trying proper or should I use some other method?It's highly ugly, but I can't think of anything else.
Another doubt is, when I run the .html of the applet
code (which is in the server), is it cached in the
client???Yes. No need to download the same stuff each time. The details are browser-specific.

Whether it is urgent or not, does not interest us. It might be urgent for you but for nobody else.

Help needed in HTTP Tunneling - urgent

Hi all,
I urgently need a working code sample of a client which sends requests to a server that redirects the request to an RMI server via RMI servlet.
Does any of you familiar of such a code sample?
Thanks

I'm sorry, but HTTP Tunneling is not working for me. I must have done something wrong.
Let me describe my configuration:
I have a server behind NAT router which connected to apache2 and tomcat 4.1 web servers. The apache2 and tomcat are not connected between them.
I deployed war file on tomcat which contains the servlet for the HTTP Tunneling which its code is:
public class RmiHttpTunnelerServlet extends HttpServlet

                command = queryString.substring(0, delim);
                param = queryString.substring(delim + 1);
            if (command.equalsIgnoreCase("forward"))
                try

Any help will be appreciated.

Help needed in selection screen - Urgent

Hi Experts,
I have a selection screen. I have three radi buttons in that selection screen. Based on the selection of the radio buttons I need to activate corresponding selection screen parameters.
e.g : if radiobutton1 is selected, njo activation needed,
       if radiobutton2 is selected, activate selection screen parameter p_one,
       if radiobutton3 is selected, activate selection screen parameter p_two.
All three radiobuttons are attached to the same radio button group.
I have assigned the parameters p_one, p_two, p_three to MODIF ID as follows.
p_one - NULL
p_two - t01
p_three - t02.
on the selection of a radio button I want the corresponding parameter to get activated.

The Compliation is totally fine,applet loads, but the gui components are not diaplyed.Any suggestions.
Thank you.

That's not really an applet. Or it's a half-done one. It looks like you just took a standalone app (with its own frame and everything), added "extends JApplet", commented out a few things that absolutely shouldn't work, and otherwise changed almost nothing.
The browser won't invoke the applet's main() method. I guess that's not a problem, but are you aware that it's not being invoked?
An applet is a kind of panel. You shouldn't be creating frames. You should put all the GUI elments in the panel...which it appears you did, but can you actually get rid of the irrelevant code? Furthermore, when you post code on these forums, you should wrap it in [code][/code] tags; it makes it much easier to read.
An applet shouldn't call System.exit(). You'll probably get a security exception if you try running that.
That addComponent method looks suspicious to me. You're changing the columns and row of the same object over and over again. I'm not a GUI expert, so maybe I'm wrong, but that seems really wrong.
You shouldn't need to call this.setVisible(true) for an applet.
I'd suggest cleaning your code up, and maybe moving some of that stuff out of the constructor anyway. In an applet it might be better placed in init().

Help needed!!! Urgent!!! Josepheus problem ...

I need help to solve this problem. I am able to show the winner of this game and I can show the players who are eliminated each round. However, I cannot write the program that just solve a single round instead of the whole game. I need to write a program that, until the game is over, the program should print the state of the game after each round. Once the game is over, the program should indicate which player was the winner.
Background information:
The Josepheus problem is a game in which N people are sitting in a circle. A person is designated to be the starter and is given a hot potato. The potato is then passed around the circle; after a designated number of passes (let's call this the pValue), the person holding the potato is eliminated. Thus, the circle now consists of one fewer people. The game then continues with the person who is sitting immediately after the eliminated player picking up the potato. The last remaining player wins.
For example, consider a game with 6 players and pValue = 3.
Round 1:
Player 0 starts with the potato (note: being good Computer Scientist, we'll start counting at 0). The potato is then passed to Player 1, then to Player 2, and then to Player 3. Player 3 is left with the potato, and is thus is eliminated. The circle now consists of Players 0, 1, 2, 4, and 5. The potato is given to Player 4.
Round 2:
Player 4 starts with the potato. The potato is then passed to Player 5, then to Player 0, and then to Player 1. Player 1 is left with the potato, and is thus eliminated. The circle now consists of Players 0, 2, 4, and 5. The potato is given to Player 4.
and so on ...
Would somebody please help me!!!

Help needed for HSC project, urgent.

Hi,
I am having further troubles. In my storybook on the first page all the buttons are appearing, I do not want this. How do I code to fix that, the only button I want on the first page is "page1_btn"
will paste my coding into here, and could you please tell me what to do to fix this ?
page2_btn.visible= false;
p3_first_btn.visible= false;
page1_btn.addEventListener(MouseEvent.CLICK,turnpage2);
function turnpage2 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page2");
page1_btn.visible = false;
page2_btn.visible= true;
page2_btn.addEventListener(MouseEvent.CLICK,turnpage3);
function turnpage3 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3");
page2_btn.visible= false;
p3_first_btn.visible= true;
p3_first_btn.addEventListener(MouseEvent.CLICK,turnpage3a);
function turnpage3a (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3a");
p3_first_btn.visible= false;
And, also the reason why I am setting the buttons to visible= true; at the start and visible= false; at the end is because I can only have one button for each page.
Please help someone,
Regards,
Adam

In your code you are:
1. setting page2_btn and p3_first_btn to visible false, then you set an event listener and function for page1_btn.
2. setting page2_btn to be visible true and setting an event listener and function for that button.
3. setting p2_first_btn to be visible true and setting an event listener and function for that button.
If all of this code is in the same frame, then you are turning all of the buttons' visible properties to true.
If you only want one of those buttons to be visible at any one time then set the visible property for page2_btn to true at the end of the function turnpage2 and do the same for p2_first_btn.
Something like this:
page2_btn.visible= false;
p3_first_btn.visible= false;
page1_btn.addEventListener(MouseEvent.CLICK,turnpage2);
function turnpage2 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page2");
page1_btn.visible = false;
page2_btn.visible= true;
page2_btn.addEventListener(MouseEvent.CLICK,turnpage3);
function turnpage3 (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3");
page2_btn.visible= false;
p3_first_btn.visible= true;
p3_first_btn.addEventListener(MouseEvent.CLICK,turnpage3a);
function turnpage3a (evt:MouseEvent):void {
screen_movie.gotoAndPlay ("page3a");
p3_first_btn.visible= false;
You may have to make more changes, I'm guessing at what is going on in your movie.

Help needed exporting PDF! urgent!

Hello, I`ve been working on a catalog for the past 2 months, and now its done. But when I export it to PDF only one side(right) has pages numbered and head and foot info. What am I donig here? When the documet is still in indesign everything is normal and there. I has to be someking of master problem, but all the masters applied to pages look fine. Please help, as the thing is supposed to go into print today.

Do you have pages with different master pages throughout the document, for example does your pages panel look like this
|A
A|A
A|B
B|B
B|B
B|C
C|C
C|D
Where A master page is paired with B, starting a new section, B is paired with C (starting section) etc.
If you do, make sure that no object crosses the Spine even by .00001 mm, as this causes the Left Master items to disappear when A meets B and C meets D.
that make sense?

Help needed on BEx Query Urgently

Hello Gurus,
              I have query, in which, when a user logs in, the user will see list of customers assigned to that particular user only, if they exist in cube. When I execute the report RSRT or ADHOC, it is displaying all the customers correctly, but not the values. But, when I go to 'Key Figure Definition' in RSRT for each customer, it is showing correct values, but displaying different value in the query.
EX.
Actual Values for the customers:
customer1   100
customer2     50
customer3   125
customer4   135
customer5   150
customer6   1000
Result         1550
But it is displaying like this, when I execute
customer1   1000
customer2   1000
customer3   1000
customer4   1000
customer5   1000
customer6   1000
Result         1000
I couldn't figureout this issue.
Any help is appreciated with points.
Thanks In Advance

I checked the report again. It is actually displaying like this..
Actual Values for the customers:
customer1 100
customer2 50
customer3 125
customer4 135
customer5 150
customer6 1000
Result       1550
But it is displaying like this, when I execute
customer1 1550
customer2 1550
customer3 1550
customer4 1550
customer5 1550
customer6 1550
Result      1550
Result is some how over writting the values for single values.

Help needed for compiling error URGENT

Hello,
I have been looking at this compilation error for a while and I cannot figure it out.
I am compiling with this command:
javac -classpath classes -sourcepath src -d classes src\pshah3\library\gui\GraphicalGui.java
The error is:
C:\java\hw5>javac -classpath classes -sourcepath src -d classes src\pshah3\library\gui\GraphicalGui.java
src\pshah3\library\gui\GraphicalGui.java:32: error while writing <anonymous pshah3.library.gui.GraphicalGui$1>:classes\pshah\library\gui\GraphicalGui$1.class
(The system cannot find the path specified)
public void actionPerformed(ActionEvent e) { System.exit
(0); }
Why is it telling me that it cannot find the path, when it has to create the .class file itself?
I would appreciate some insight into this problem?
Thanks,
Premal

Thank you for you help, but i'am still a bit confused. The "pshah" was a typo, it should have been pshah3, so that's not the problem. Here's a more detailed explanation of what i'am trying.
I am declaring the exitlister class in the following path:
c:\java\hw5\src\pshah3\library\gui
The file is fairly simple, it looks like this.
package pshah3.library.gui;
import java.awt.*;
import java.awt.event.*;
public class ExitListener extends WindowAdapter{
     public void windowClosing(WindowEvent event) {
          System.exit(0);
The other file that i'am including is in the same location...it starts out like this.
package pshah3.library.gui;
import pshah3.library.*;
import java.io.*;
import java.util.*;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class GraphicalGui {
          public static void main (String[] args){
          JFrame backGround = new JFrame("Tech Library");
          backGround.setSize(400,150);
          backGround.addWindowListener (new ExitListener());
          Container content = backGround.getContentPane();
I am compiling from the c:\java\hw5 directory with the command
javac -classpath classes -sourcepath src -d classes src\pshah3\library\gui\GraphicalGui.java
I am doing this so all the classes go in a "classes" directory with the same heirarchy as the source.
Do you think i'am doing something funky with the packages??
Again the error is:
src\pshah3\library\gui\GraphicalGui.java:39: error while writing <anonymous pshah3.library.gui.GraphicalGui$1>: classes\pshah3\library\gui\GraphicalGui$1.class
(The system cannot find the path specified)
public void actionPerformed(ActionEvent e) { System.exit
(0); }
THANKS A LOT!!!

.This was working in 1.4.2 and 1.3.1_08. Anyone else have this problem?

Sorry, copied and pasted the following, hope it helpes.
The following examples are for a win 2000 machine, for linux
you have to use alternative paths but I think the commands
are about the same.
The SUN jre doesn't care about IE settings, if an applet is signed it will ask the user "do you trust", if
the user chooses yes or always the applet can do pretty much anything.
Because anybody can sign an applet so it will pop up the do
you trust dialog I prevent this dialog from popping up by
adding the following to the
C:\Program Files\Java\j2re****\lib\security\java.policy
under grant { [/b]
[color red]
permission java.lang.RuntimePermission "usePolicy";
[color]
You now need to set up special permissions for sites that
need it, signed applets get no special treatment since you
specified in the java.policy that policy should allways be
used.
When your applet needs to do something it normally could
not do (applet security) [b]and it needs to do this
when a user clicks on a html button (applet method called
from javascript), than all the signing and policy settings
in the world wouldn't work Unless you grant all permission
to all code.
This is because the Java Plug-in executes methods with
applet sandbox security restrictions.
http://archives.java.sun.com/cgi-bin/wa?A2=ind0404&L=java-security&F=&S=&P=4012
To solve this you can start a new thread that checks ...
times a second if a variable meets certain conditions.
These conditions are changed with public methods called
from JavaScript. When a variable meets certain Conditions
this thread will start the method that will perform
normally restricted tasks.
Here is an example where the applet doesn't work
(the batchfile, html file are OK)
Note that running this code with Mozilla on my w2k machine
crashes Mozilla (not on my Fedora machine)
Batch file to sign the applet: (please note this will
delete some files)

}When you put the files in c:\temp, run the batch file to
compile and sign the applet and then open the html file you
will be asked if you trust ... you can say yes and from
init the applet can read user.home. Click on the button and
you will get the following stack trace:
java.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)

     at sun.plugin.com.DispatchImpl.invoke(Unknown Source)Conclusion: the applet can read user.home but not from
JavaScript.
Here is the applet that does work because a method called
from javaScript doesn't perform a restricted task.
