Java Error -- Need help

I am getting the error below when i try to pass along values with the help of Java Beans...Can anyone explain what I am doing wrong if your at all familiar with an error similar to this one?
org.apache.jasper.JasperException: /web/loginresponse.jsp(41,18) The value for the useBean class attribute org.mypackage.login.LoginHandler is invalid.
Thanks,
Jeff

Well the documentation for this host appears here
It seems they have Apache and Tomcat installed, and configured to handle this.
The context path of each virtual site is: "/home/domain/public_html/WEB-INF".So your compiled servlet will probably need to be deployed to
"/home/domain/public_html/WEB-INF/classes/org/mypackage/login/LoginHandler.class".

Image size and mime type.. non-java guy needs help

Image size, mime type.. non-java guy needs help
Im not at all familiar with java so this is really weird for me to work out. I?ve been doing it all day (and half of yesterday).
Im trying to write a custom clodFusion tag in java that gets the width, height, size and MIME types of a given file. I?ve been trying to get it to work on the command line first. I can get the width and height but cant get the size and the MIME type.
Here is what I got
/*import com.allaire.cfx.*;*/
import java.awt.image.renderable.*;
import javax.media.jai.*;
import com.sun.media.jai.codec.*;
import java.io.*;
import java.util.*;
public class ImageInfo {
private RenderedOp image = null;
private RenderedOp result = null;
private int height = 0;
private int width = 0;
private String type = "";
private String size = "";
public void loadf(String file) throws IOException
file = "80by80.jpg";
FileSeekableStream fss = new FileSeekableStream(file);
image = JAI.create("stream", fss);
height = image.getHeight();
width = image.getWidth();
System.out.println(height + "\n");
System.out.println(width);
System.out.println(type);
public static void main(String[] args) throws IOException {
ImageInfo test = new ImageInfo();
test.loadf(args[0]);
can anyone please help me out to modify the above so I can also print the mime type and the file size to screen.
thanks for any help

any suggestions?

What version of OS X? Some people have luck by clearing their caches. This can be done with Applejack in 10.5. Onyx will work in SL.

Why my java program work well under C:\, but can't under D:\Java today? It worked well even yesterday. I had tried the "Hello World", it can not work under D:\Java either.
when I enter the "java d:\java\Hello" order(after javac of cause), those displays are here:

The Hello.java has no problem,and it worked well even yesterday!
I just don't know what had happened.
Someone who can help me please reply or email at [email protected]
Thank you!

The simple "Hello World" can work under Editplus, but can't under DOS.
The error appears as the same. I don't know what I should do, could you tell me please?
Thank you!First test whether environment variables had been set properlyor not
To test :-
1) Open cmd
2) type java
3) If it runs that means you have set it properly
Then go to your program directory i.e d:\java\
and type
javac Hello.java //to compile it and then
java Hello //To run it

IMac: Install Java 7 need help!

Hello, I've an iMac with the newest software version, I want to install java 7 on it for a game server, but when I download it from java.com and I install it and start the server, it still says: Computer on java 6, update to 7 to run server. I already tryed to install with Terminal and direct acess to System Library, it shows that java 7 is installed, but I have to delete java 6. When I delete all java versions, apple says I have to install java SE6, what isn't java 7 but java 6! Help please!!!

The Oracle JRE is only a web plugin. If you need server-side Java, you'll have to use the Apple-supplied Java 6 runtime, or else the Oracle JDK (which is not a drop-in replacement for Apple's Java.) If your server application depends on Java 7, you'll most likely have to run it on another operating system.

Hi
I think you need to configure proxy for the JRE
If you are using windows Go to control panel , you will find an icon called java plugin. if you have installed multiple JRE you will find multiple icons . Select the one which is configured to browser.
You will find a proxies tab in that window , add the proxy details there
Hope this helps you

Newbie to Java who needs help..

Hello all.
I am having some troubles making a random walker/Drunkard. What I have to do is make it that the user inputs the starting X, Y coordinates and the amount of steps he has to walk. After that, it is post to print back the new coordinates he walked to and the distance of his new coordinates is to the starting one. I am new to java so I am confused.. This is what I have so far..
import java.util.*;
public class Drunkard {
    private int x;
    private int y;
    private int numSteps;
    private int Distance;
    private int moveDrunk;
    public Drunkard() {
        this.x = x;
        this.y = y;
        this.numSteps = 0;
    public int getX() {
        return x;
    public int getY() {
        return y;
     public int getSteps() {
        return this.numSteps;
    private void move(int numSteps);
    private void moveDrunk(){
    moveDrunk = (int) (Math.random() * 4);
    public int getmoveDrunk() {
        return moveDrunk;
public boolean getDistance{
(int)(Math.sqrt((getX()*getX()) + (getY()*getY())));{
return Distance
import java.util.Scanner;
public class DrunkardSimulator
    public static void main (String[] args)
        Scanner scan = new Scanner(System.in);
        System.out.print ("Enter the number of steps: ");
        numSteps = scan.nextInt();
        System.out.print ("Enter the starting x coordinate: ");
        x = scan.nextInt();
        System.out.print ("Enter the starting y coordinate: ");
        y = scan.nextInt();
        Drunkard drunk = new Drunkard();
        System.out.println("The drunk moved to X" +drunk.getX() + ", y " + drunk.getY() && "a distance of " + drunk.getDistance());
}Any help would be nice.

Sorry. I should have stated what I need help with..
I need help with making him move randomly when the user types in the x,y starting coords, and the amount of steps he has to walk from what the user inputs. I also need help printing out the new x,y coords he walked to randomly and the distance his new coords are from where he first started at (the coords the user the typed in.)
I have two files:
Drunkard.java
import java.awt.*;
import java.util.*;
public class Drunkard {
    private int x;
    private int y;
    private int numSteps;
    private int Distance;
    private int moveDrunk;
    public Drunkard(int x, int y) {
        this.x = x;
        this.y = y;
        this.numSteps = 0;
    public int getX() {
        return x;
    public int getY() {
        return y;
     public int getSteps() {
        return this.numSteps;
    public void moveDrunk(int numSteps){
         for (int i=0;i<numSteps;i++) {
        if(rand.nextInt(2)==1) { x+=1; } else { y+=1; } }
    public int getDistance(){
(int)(Math.sqrt((getX()*getX()) + (getY()*getY())));{
return Distance
}And DrunkardSimulator.java
import java.util.Scanner;
public class DrunkardSimulator
    public static void main (String[] args)
int x;
int y;
int numSteps;
        Scanner scan = new Scanner(System.in);
        System.out.print ("Enter the number of steps: ");
        numSteps = scan.nextInt();
        System.out.print ("Enter the starting x coordinate: ");
        x = scan.nextInt();
        System.out.print ("Enter the starting y coordinate: ");
        y = scan.nextInt();
        Drunkard drunk = new Drunkard(x,y);
        drunk.moveDrunk(5); //5 steps
        System.out.println("The drunk moved to X,Y" + drunk.getX() + drunk.getY() + drunk.getDistance());

this is more of a jdbc question rather than an internationalization. You might be able to get more help if you post it in java programming section.

New to Java and need help with this program..please!

I'd really appreciate any helpful comments about this program assignment that I have to turn in a week from Friday. I'm taking a class one night a week and completely new to Java. I'd ask my professor for help, but we can't call him during the week and he never answers e-mails. He didn't tell us how to call from other classes yet, and I just can't get the darn thing to do what I want it to do!
The assignment requirements are:
1. Change a card game application that draws two cards
and the higher card wins, to a Blackjack application
2. Include a new class called Hand
3. The Hand class should record the number of draws
4. The application should prompt for a number of draws
5. The game is played against the Dealer
6. The dealer always draws a card if the dealer's hand total is <= 17
7. Prompt the player after each hand if he wants to quit
8. Display the total games won by the dealer and total and the total games wond by the player after each hand
9. Display all of the dealer's and player's cards at the
end of each hand
10. Player has the option of drawing an additional card after the first two cards
11. The Ace can have a value of 11 or 1
(Even though it's not called for in the requirements, I would like to be able to let the Ace have a value of 1 or an 11)
The following is my code with some comments about a few things that are driving me nuts:
import java.util.*;

I don't know how to go about making and calling a method or class that will combine the total cards delt to the player and the total cards delt to the dealer. The rank() method only seems to give me the last cards drawn to compare with when I try to do the tests.**/

}

Thank you so much for offering to help me with this Jamie! When I tried to call change value using:
Card dealer = (d.changeValue());
I get an error message saying:
Incompatible types found: int
required: Card
I had my weekly class last night and the professor cleared up a few things for me, but I've not had time to make all of the necessary changes. I did find out how toString worked, so that's one question out of the way, and he gave us a lot of information for adding another class to generate random numbers.
Again, thank you so much. I really want to learn this but I'm feeling so stupid right now. Any help you can give me about the above error message would be appreciated.

Java noob needing help - First applet won't compile

I'm trying to make a simple audio player applet for a web page. The basic way it works is: There are four buttons Play 1, Play 2, Play 3 and Stop, as well as a label for applet credits, a label for music credits and a label for the applet's current status.
This is the applet so far:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
public class wifflesaudio extends Applet implements MouseListener {
add(new Label("(applet credits"));
add(new Label("(music credits"));
Label labelDoing = new Label("Stopped");
Button buttonOne = new Button("Play 1");
Button buttonTwo = new Button("Play 2");
Button buttonThree = new Button("Play 3");
Button buttonStop = new Button("Stop");
add(buttonOne);
add(buttonTwo);
add(buttonThree);
add(buttonStop);
addMouseListener(this);
String clipName[] = {getParameter("clipOne"),
getParameter("clipTwo"),
getParameter("clipThree")};
AudioClip clipOne;
AudioClip clipTwo;
AudioClip clipThree;
int whichIsPlaying = 0;
public void loadClip(int clipNumber) {
switch (clipNumber) {
case 1:
if (AudioClip.clipOne == null) {
try {
labelDoing = "Loading clip 1...";
clipOne = Applet.newAudioClip(newURL(getCodeBase(), clipName[1]));
catch (MalformedURLException e) {
labelDoing = "WARNING: clip 1 didn't load";
if (clipOne != null) {
clipTwo.stop();
clipThree.stop();
clipOne.loop();
whichIsPlaying = 1;
break;
case 2:
if (clipTwo == null) {
try {
labelDoing = "Loading clip 2...";
clipTwo = Applet.newAudioClip(newURL(getCodeBase(), clipName[2]));
catch (MalformedURLException e) {
labelDoing = "WARNING: clip 2 didn't load";
if (clipTwo != null) {
clipOne.stop();
clipThree.stop();
clipTwo.loop();
whichIsPlaying = 2;
break;
case 3:
if (clipThree == null) {
try {
labelDoing = "Loading clip 3...";
clipThree = Applet.newAudioClip(newURL(getCodeBase(), clipName[3]));
catch (MalformedURLException e) {
labelDoing = "WARNING: clip 3 didn't load";
if (clipTwo != null) {
clipOne.stop();
clipTwo.stop();
clipThree.loop();
whichIsPlaying = 3;
break;
public void actionPerformed(ActionEvent evt) {
Button source = (Button)evt.getSource();
if (source.getLabel().equals("Play 1")) {
loadClip(1);
if (source.getLabel().equals("Play 2")) {
loadClip(2);
if (source.getLabel().equals("Play 3")) {
loadClip(3);
if (source.getLabel().equals("Stop")) {
clipOne.stop();
clipTwo.stop();
clipThree.stop();
Naturally, it doesn't work. When I try to compile it with javac I get 21 errors thrown back at me. Being the noob that I am I have absolutely no idea why it isn't working, so I'm turning to all you clever people for some advice. :)

Think anyone's going to copy your code into their own machine and compile it to see those messages for you? Well I did. Since there are a zillion error messages, I think it's fair to help a little bit:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
// no need to implement MouseListener
// see below
public class wifflesaudio extends Applet {
    Label labelDoing = new Label("Stopped");
    Button buttonOne = new Button("Play 1");
    Button buttonTwo = new Button("Play 2");
    Button buttonThree = new Button("Play 3");
    Button buttonStop = new Button("Stop");
    String[] clipName;
    AudioClip clipOne;
    AudioClip clipTwo;
    AudioClip clipThree;
    int whichIsPlaying = 0;
    // statements in JAVA must be located with methods or constructors
    // here is the default constructor (with no param)
    wifflesaudio() {

        add(buttonTwo);
        add(buttonThree);
        add(buttonStop);
        clipName = new String[3];
        clipName[0] = getParameter("clipOne");
        clipName[1] = getParameter("clipTwo");
        clipName[2] = getParameter("clipThree");

Failed to connect Error - Need Help, Please

I installed , created the simple "Hello" program and it ran fine on the simulator.
Then, I click the run OTA and now I'm in deep yogurt!
I get the message:
*** Error ***
Failed to connect to device 0!
Reason:
Emulator 0 terminated while waiting for it to register!
BUILD SUCCESSFUL (total time: 4 seconds)
I just want to restore things to what they were before I selected Run OTA. I've been reading for the past 3 hours and haven't found out to restore. I even deleted and re-installed but, still get the same meassge (probably some saved java pref file...). Anyway, HOW TO RESTORE to a virgin setup????
Thanks

... I read somewhere I need to reboot - I did and it took care of it.

Vital Program no longer works after updating JAVA SE - Need help fast!

System Info:     Window Vista Home Premium (Service Pak 2)
          Intel Core 2 CPU T5200 @1.60 GHz
          RAM     2 GB
          32 bit OS
JAVA 6 SE Update 18 (build 1.6.0_18_b07)
I am just an old guy, not a techie, with diabetes who uses Bayer?s CLUCOFACTS Deluxe for Windows to monitor/manage my blood sugars.
A couple of weeks ago I had a warning message on starting up the program which led to a call to Bayer. They advised me to update my JAVA applications, which I did. Since that time, I have not been able to open the Bayer?s CLUCOFACTS Deluxe for Windows application.
I searched the web to see if anyone had a similar problem. It appears a number of people have the same issue and have not been able to solve the problem. I signed up and logged into the JAVA site to see if there might be some clue . . . the lingo is over my head. I did check JAVA, via the site to insure it was running properly on my local disk.
My gut feeling is a link was broken when the original JAVA was cleaned from the computer in preparation to do a fresh download of JAVA. When the current version was loaded, I was unable to open the application. Thinking it might be a matter of how the programs were loaded, I then downloaded/reinstalled Bayer?s CLUCOFACTS Deluxe for Windows without any luck.
I am willing to give this another go if you have any specific advice that may help me find a solution. Because I am hearing impaired, the telephone is not an option for working through this problem. We have to rely on email.
I need very simplified, step by step, instructions get the program up and running again. (Example: Start > Control Panel > JAVA right click > Open)
I am not into programming or the development side of JAVA; I am just a simple user who needs some advice on how to get the program up and running again in order to manage my diabetes.
Thank you so very much for taking time to help me!
Jim

Seems you're [not alone|http://www.health-forums.com/alt-support-diabetes/bayer-glucofacts-deluxe-problem-136625.html] <-- link
Best guess advice is to uninstall Java completely and then install the Java version that came on your GLUCOFACTS (not CLUCOFACTS) CD. Then, from Control Panel -- > Java, clear the checkbox for "Check for updates automatically".
Good luck!

Oh, it's probably not a CD but the Java folder on your USB device.
