Help with JAI in java applet

I'm fairly inexperienced with java, but I'm hopeful someone here won't mind helping.
I am using netbeans and have a project to let a user upload files or scan them in with a usb scanner. I've imported icepdf to the libraries and referenced it in the jnlp file and it worked fine. I did the same with jai_windows-i586.jar and I get this error when trying to upload
Exception in thread "AWT-EventQueue-2" java.lang.NoClassDefFoundError: com/sun/media/jai/codec/SeekableStream
Caused by: java.lang.ClassNotFoundException: com.sun.media.jai.codec.SeekableStream
I expanded the jar file and found it contained an exe. jai-1_1_3-lib-windows.i586.jre.exe. I found that if I run that exe [(found here)|http://download.java.net/media/jai/builds/release/1_1_3/] on any pc locally, I will not get the errors on that pc.
Am I referencing it incorrectly?
<resources>
<j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" max-heap-size="1024m" />
<jar href="ScanAreaUI.jar" main="true" />
<jar href="icepdf-core.jar"/>
<jar href="jai_windows-i586.jar"/>
<nativelib href="JTwain-Native.jar" />
</resources>
Do I need to make the applet install the exe located in the jar? I've tried to find information on how to do that without much luck so far.
Thanks for any advice/help.

If it's not finding your "exe" file, then you have an OS path problem. You can either change your path variable in Windows or you can move that "exe" to a location where you already have a path defined. You do realize that when you use features of JAI that are not incorporated in to the JDK, you'll have to have the JAI package loaded on every machine you ever want to run your project.

There were errors
and i have no idea why im geting the depreciation note

I think if you use BufferStrategy in an Applet, you have to do it on a Canvas and add the Canvas to the Applet. I'll have to check to make sure.

Desperately need some help with client-server java programming

Hi all,
I'm new to client server java programming. I would like to work on servlets and apache tomcat. I installed the apache tomcat v 5.5 into my machine and i have sun java 6 also. I created a java applet class to be as a client and embed it into an html index file, like this:
<applet code="EchoApplet.class" width="300" height="300"></applet>However, when I try to run the html file on the localhost, it print this error: classNotFoundException, couldn't load "EchoApplet.class" class. On the other hand, when I open the index file on applet viewer or by right clicking, open with firefox version 3, it works.
I thought that the problem is with firefox, but after running the applet through the directory not the server, i found that the problem is not any more with firefox.
Can anyone help me to solve this problem. I'm working on it for 5 days now and nothing on the net helped me. I tried a lot of solutions.
Any help?

arun,
If the browser is going to execute $myApplet, first it must get the $myApplet.class from the server, right?
So it follows that:
1. $myApplet.class must be acessible to server, and
2. the server must know exactly where to find $myApplet.class
So, the simplest solution is to is put the $myApplet.class in the same directory as the HTML file which uses it... then your applet tag is simple:
<applet height="200" width="400" code="$myApplet.class" ></applet>* The height & width attributes are required
* Note the +.class+ is required in the code attribute (a common mistake).
* This works uniformly (AFAIK) accross all java-enabled browsers.
* There are incompatibilities with the codebase attribute. Poo!
Cheers. Keith.

Need help with long term Java problems

I've been having problems with Java on my computer for about a year now, and I'm hoping that someone here can help me out.
Java used to work fine on the computer when I first got it (a Dell laptop) and I hadn't installed anything myself. But then one day it stopped loading Java applets, and hasn't worked since. By this, I mean that I get the little colorful symbol in a box when I try to play Yahoo games, use the http://www.jigzone.com site, go to chat rooms, etc. Java menus on websites like http://www.hartattack.tv used to work still, but lately they've been giving me that symbol too.
I've tried downloading a newer version of Java, but nothing I do seems to work, and I don't know of anything I did to trigger it not working. I'm hoping there's a simple solution to this, and I'm just dumb.
Thanks.

This might be way off, but it's something that's tripped me up in the past:
If you are using Sun's Java plugin, the first time you go to a site that has a particular Java applet, you may be asked to approve/reject a security request.
If you have clicked on any other windows while the request is first being loaded (which can take some time, because this is swing based), then the security dialog box does not pop to the top of the window stack, and doesn't add an entry into the task bar.
It appears that Java just doesn't work, but it's actually waiting for you to click "Yes". You can check this by hitting alt-tab and seeing if the Java coffee cup icon is one of the options.

Help with Times Table GUI applet

Hello,
I need help with an applet which inputs an integer from the user and displays the appropiate times table up to times 10 eg; user input 5 - display shows
5 time 1 is 5
5 times 2 is 10
5 times 10 is 50.
I have only managedt o get the display to show one statement eg 5 times 1 - I have tried using a for loop to show the whole table - but unlike a print statement each time the loop goes round it overwrites the data in the display box with the new data - any help would be much appreciated.
Note: it is for a programming course year 1 exercise - so I can only use basic constructs or loops to achieve this. Thanks in advance! Heres what I have so far:

Hi,
From your description, you want to achieve the following goal:
Configure Exchange to filter the attachments if the size is over 10 MB and store it in a public folder, and then forward the email to Salesforce.
Based on my knowledge, I'm afraid that it can't be achieved. Exchange can filter messages with attachments, but it couldn't store these attachments on public folder automatically. Also, I don't see any transport rule can do it.
Hope my clarification is helpful.
Best regards,

Help with my basic java

Hello i am in a high school programming class and i need help.

Next time you post code, use the CODE button or [code] and [/code] tags so that it maintains the formatting from your editor.
If two things are moving int the same direction, your adding N to both of their x-coordinates. If you want one to move in one direction and the other in the other direction, then you have to add N to one and -N to the other.

Help with a SIMPLE java thing

I've only got ONE handful of hair left.
I'm trying to build a series of dropdown boxes; a day dropdown (Mon, Tue, Wed...), a month dropdown (Jan, Feb, Mar...), a year dropdown, hour dropdown, minute dropdown, and an am/pm dropdown.
I think I want to build my dropdowns using "for" loops something like this:
for (i=0;i<12;i++) {
myStringBuffer.append("<option>" + [someUnknownFunctionThatReturnsTheFirstThreeLettersOfTheMonth(i)] + "</option>")
I've been trying to mix up various combinations of Date objects (most date functions seem to be depreciated), Calendar Objects, DateFormat Objects and SimpleDateFormat Objects but nothing seems to want to perform the function that I need.
I've had iffy success creating a calendar object, setting the Month to "i", using the getTime function to return a Date object which I can then pass to the SimpleDateFormat object using the .format(Date) function, after setting the pattern to "EEE", but it seems like just an incredibly complicated way to do what ought to be a simple function...i.e. convert a number 0-11 (or 1-12, I'm not picky) into the name of a stinking Month! Arrgh.
If anyone can help, I thank you.

I've done that before, so i'll share it with you.
import java.text.SimpleDateFormat;
import java.text.DateFormatSymbols;
import java.util.Calendar;
import java.util.Date;
public String createListOfMonth(String pName) {
StringBuffer sbMonth = new StringBuffer();
DateFormatSymbols fm = new DateFormatSymbols();
String[] arrMonth = fm.getMonths();
sbMonth.append("<select name=\"" + pName + "\">");
sbMonth.append("     <option value=\"\">Month</option>\n");
for (int i=0; i<arrMonth.length; i++) {
if (!arrMonth.trim().equals("")) {
String sValue = "0000" + (i + 1);
sValue = sValue.substring(sValue.length() - 2);
sbMonth.append("     <option value=\"" + sValue + "\">" + arrMonth[i] + "</option>\n");
sbMonth.append("</select>");
return (sbMonth.toString());
You can manipulate the symbol (either for months, days) using different locale. You can see the API for java.text.DateFormatSymbols in Java2 SE.

Im DROWNING! need help with a simple java assignment! plz someone help me!

i need help with my java assignment, with validating a sin number. easy for must who know java. im drowning... please help!

You will need to store each digit of the social insurance number in a field of its own. To validate the entry you will:
1. Multiply the 2nd, 4th, 6th and 8th digit by 2.
2. If the product of any of the four multiplications result in a value greater than 9, add the two resulting digits together to yield a single-digit response. For example 6 * 2 = 12, so you would add the 1 and the 2 to get a result of 3.
3. Add these four calculated values together, along with the 1st, 3rd, 5th, and 7th digits of the original number.
4. Subtract this sum from the next highest multiple of 10.
5. The difference should be equal to the 9th digit, which is considered the check digit.
Example of validating S.I.N. 765932546
1st digit 7
2nd digit (6*2 =12 1+2=) 3
3rd digit 5
4th digit (9*2 = 18 1+8 =) 9
5th digit 3
6th digit (2*2 = 4) 4
7th digit 5
8th digit (4*2 = 8) 8
Total 44 next multiple of 10 is 50
50-44 = 6 which is the 9th digit
Therefore the S.I.N. 765932546 is Valid
********* SIN Validation *********
Welcome - Please enter the first number: 120406780
Second digit value multiplied by 2 4
Fourth digit value multiplied by 2 8
Sixth digit value multiplied by 2 12
Eighth digit value multiplied by 2 16
Value derived from 6th digit 3
Value derived from 8th digit 7
The total is 30
Calculated digit is 10
Check digit must be zero because calculated value is 10
The SIN 120406780 is Valid
this is my assignemtn this is what i have! i dont know where to start! please help me!

Help with a Times Table Applet.

Hey,
I am a college student and I have been given the task of constructing a times table applet. Basically, I am stuck to the point of where I have no clue of what to do next. Even my college tutor is stuck as to what to do. I was wondering if you could give me any aid in helping me develop this applet fully, so that it is correct and functioning. Here it is:
import java.io.*;
import Input.*;
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
abstract class TimesTableApplet extends Applet implements ActionListener
     public void initialize();{}
     String message="";
     public void init()
     Button btnClick= new Button("Enter");
add(btnClick);
          //String line = null;
          float table = 0, range = 0, attempts = 0;
          int count = 1, reply = 1, lines = 1;
TextArea textone;
     while(reply==1)
               String line = null;
               table = 0;
               range = 0;
               ClrScr.ClrScr();
               textone = new TextArea("",10,30+12*lines);
               lines=1;
          while (( table < 1) || (table > 20) && attempts <3)
               textone = new TextArea("Input table from 1-20:",10,10);
               table = Input.readFloat();attempts++;
          attempts = 0;
               while (( range < 1) || (range > 14) && attempts <3)
                    textone = new TextArea("Input range 1-14:,10,20");
                    range = Input.readFloat();attempts++;
          if (( table >= 1) && (table <= 20))
               if (( range >= 1) && (range <= 14))
               while (count<=range)
                    textone = new TextArea(count + "x" + table + "=" + count * table);
                    count++;
                    lines++;
               count=1;
               textone = new TextArea("Would you like another go? Type '1' for yes");
               reply = Input.readInt();
     }//end while reply ==1
     }//end init
     public void paint(Graphics g)
     int count =1;
     while ( count <=80)
     System.out.println();
     count++;
}

Ok, why did you post this code? we will not be able to compile it because we are missing
the Input package not did you mention wich jar to find this (nor did google).
Syntax error in initialize

     catch(Exception e){}
     img = getImage(base,"1.gif");
     mt.addImage(img,1);
     try{
          mt.waitForAll();

I need some help with sound in Java

hi, i`m new to java. i`m having a through problems with a program i`m writing. i`ve added a song to an applet but it does not play. The code for this is:
private AudioClip music;
music = getAudioClip(
getDocumentBase(), "titantic.wav" );
Can some 1 tell me is that the write code. please help.

2 things.
1. You must also send a command to play the music file.
2. I'm not certain, but I think that you can only load .au files this way.

Need help with running a Java program on Linux

I am trying to get a Java program to run on a Linux machine. The program is actually meant for a Mac computer. I want to see if someone with Java experience can help me determine what is causing the program to stall. I was successful in getting it installed on my Linux machine and to partially run.
The program is an interface to a database. I get the login screen to appear, but then once I enter my information and hit enter the rest of the program never shows, however, it does appear to connect in the background.
Here is the error when I launch the .jar file from the command screen:
Exception in thread "main" java.lang.IllegalArgumentException: illegal component position
at java.awt.Container.addImpl(Unknown Source)
at java.awt.Container.add(Unknown Source)
I am not a programmer and I am hoping this will make some sense to someone. Any help in resolving this is greatly appreciated!

Well, without knowing a little bit about programming, and how to run your debugger, I don't think you're going to fix it. The IllegalArgumentException is saying that some call does not like what it's getting. So you'll have to go in an refactor at least that part of the code.
