How could I to load my applet from local

hI all,
How can i to load my applet from local file system.
Thanks

Put it anywhere you want. Put the associated HTML file in the same directory as your .class file and double click on the HTML file. Your browser should open up and display your Applet.

ClassFormatError when attempting to load an applet from within a JSP

Greetings everyone.
I have a problem that i seem unable to solve.
I've created a web application. I'm using Java 1.4.2_05 and Tomcat. Right now i'm trying to load an applet from a JSP and i'm getting an error that, try as i might, i can't understand why it happens.
Here is some detailed info:
The applet's code:
package smpb.myapp.controllers;
import java.applet.Applet;
import java.awt.Graphics;
public class GUIApplet extends Applet
     public void init()
     public void stop()
     public void paint(Graphics g)
              g.drawString("Hey hey hey",20,20);
           g.drawString("Hellooo World",20,40);
The JSP's code:
<%@ page language="java"
               import="java.util.*"
               session="true" %>
<%
     String name = (String) request.getSession().getAttribute("userName");
%>
<html>
     <head>
          <title>Login</title>
     </head>
     <body>
          <h1><p align="center">Application</p></h1>
          <br>
          Welcome <%= name %>! Thank you for logging in!
          <br><br><br>
          <applet align="middle" code="smpb.myapp.controllers.GUIApplet.class" codebase="./" archive="MyApp_applets.jar">
               Your browser does not support this feature.
          </applet>
          <br><br>
          <a href='<%=request.getContextPath() + "/LogOut"%>'>Log Out</a><br>
     </body>
</html>-------------------------------------------
When i reach this JSP the applet fails to load and i get the following error message at the java console:

The JSP is in the root directory of the web application's path right along with the jar file. The jar file itself has the following structure:
Archive: HelpDesk_applets.jar
Length     Date   Time    Name
        0 05-17-06 12:17   META-INF/

      900                   6 filesNow, i've tried loading the very same jar file that i use in the JSP through a static HTML which is virtually identical to the JSP i presented and everything works just fine. I've checked and rechecked to see if all the permissions to access the jar file were accurate, i checked to see if Tomcat had it's MIME settings correctly configured so that there was no chance that the files were being corrupted during the load (as that is a usual cause for the problem, or so i've gathered) but to no avail. I've searched the web, including these forums, and found similar problems but no conclusive solution. I can't seem to figure out, at all, what could possibly be wrong. Does anyone have any ideas? I've tried to be as thorough as i could from the start, so, any help would be deeply appreciated.

Hi mshah101,
This can happen if the applet is compiled using an higher version of java and the browser is pointing to an older version (even if minor version number is higher)

No. purchases are forever tied to the apple ID used to buy them. Delete them and buy your own copies.

How could I change my telephone number from iMessage ?

How could I change my telephone number from iMessage ? I've try in my Apple ID and doesn't work.

Hi,
On your iPhone Add the Apple ID
On the Mac then Accept the pop up(s) that appear saying the iPhone is using the ID and iPhone number.
Untick the old number in the list for Receive At and Start Conversation From drop down if it is the listed item.
For complete removal you have to delete a .plist or two.
Open a Finder window
Use the Go Menu whilst holding down the ALT key
Select the Library that appears.
Navigate to the Preferences
Find com.apple.imservice.imessages.plist and com.apple.imessage.bag.plist and drag them to the Trash.
Restart the app on the Mac.
It will ask for the Apple ID.
It should get the pop ups about the iOS device.

How to tell if loaded file came from cache or not?

Trying to work out how I can tell if a downloaded file came from the cache or was freshly downloaded over the net. I need this because users will download multiple files and I am trying to give make an accurate downloader for them. I have made them download a sample file which I have made not to cache by doing the following:
private var _loader:URLLoader;
private var _rootPath:String; = "http:/example.com/speedTest/f4v/";
private var _startDownloadTime:int;
private var _targetSpeed:Number //set elsewhere
private function loadTestSpeedFile():void
            var fileRequest:URLRequest = new URLRequest();
            fileRequest.url = _fullFilePath + "speedTest.f4v";
            var variables:URLVariables = new URLVariables();
            variables.nocache = new Date().getTime();
            fileRequest.data = variables;
            _startDownloadTime = flash.utils.getTimer();
            _loader.load(fileRequest);
private function speedTestHandler(e:Event):void
            var endDownloadTime:int = flash.utils.getTimer();
            var timeElapsed:Number =   endDownloadTime - _startDownloadTime;
            timeElapsed = timeElapsed/1000;
            var bytesPerSec:Number = (SIZE_OF_TEST_FILE/timeElapsed);
            var currentSpeedFactor:Number = bytesPerSec/_targetSpeed;
            trace("Speed Test file downloaded in " + timeElapsed + " secs at " + bytesPerSec + " bytes a sec : speedFactor " + currentSpeedFactor);
               //remove this handler and download as normal from a list of files
            _loader.removeEventListener(Event.COMPLETE, speedTestHandler);
            _loader.addEventListener(Event.COMPLETE, completeHandler);
          //download the rest of the files
            download();
I could work out if the other files are downloading much more quickly (say 20X quicker) than the speedTest rate worked out here and then discount it from calculating the download speed and estimated time remaining.
However, it would be much better if there was a way to access properties on the URLoader on the Event.COMPLETE handler to see if the file 'downloaded' was taken from the cache or not. Anyone know of way of doing it more elegantly than the hack described in the last sentence?

Kglad,
Thanks for the interest and reply. Yes, you are right the file load preventing the file being cached is stictly a different matter from that which is bugging me. I am, however, using the Progress Event (as in flash.events.ProgressEvent ) in the following event handler listening to it:
private function progressHandler(e:ProgressEvent):void
            var percent:Number = (e.bytesLoaded/e.bytesTotal)*100;
              //other code to resize the gui loader ie scaling it to the percentage.
Again this just tells me how much has been loaded each time the event is fired. On the Event.COMPLETE handler I am getting the load timings pretty much as per the
speedTestHandler(e:Event) I posted. The only difference there is that it loads from an array of filenames (most but not all of which can change on later replays - hence some will be cached and some not) What i need to know is where the file is loaded from - either from the server or the local systems cache. The only way round this is to discard very quick downloads (which must be from the cache) from true calculating download speeds but that is a bit hit and miss. I am asking for a better solution. Hope that makes sense...

How to load an image from local disk?

Hi!
I have spent hours on the net searching for an example, that
could
show me how could I make a flex script that user could browse
(like fileReference.browse() ) for a
file (picture) and then show this picture in the browser (so
the source of some existing picture would change).
I found only multiple solutions on how to upload a picture,
but
that is not the thing I wanna do. I want a user to load a
picture from
his disk and simply to be seen in a browser (on a page).
I tried programming it alone, but the FileReference class has
no attribute path or similar, that I could use for source of my
image.
Please help, I need to do this urgently.
Thank you very very much
Gus

OK, I tried without FileReference, simply by changing String
variable of the source path when calling image.load(path), but it
works ONLY FOR REMOTE pictures (online), I also tried with
[Bindable]
[Embed(source="C:/somePicture.jpg")]
public var _img0:Class;
, but it appears that you CANNOT CHANGE THE PATH DOURING
EXECUTION (dinamically)
So please, someone?
Is it even possible to do that?
I could try uploading picture and then downloading, but why
would I need a server side if I don't need it...

Newb - Loading an applet from a specific location (local) help please

Hi guys,
I am not familiar with java applets at all, we have a 3rd party solution, for which i need a ...... solution
There is a website v4.globalmentoring.com/clientJava/clientlogin.asp
on this site, if you click on a topic, and then select "Get Instructor help" link
you will be taken to a new window (this is a chat window)
if you "view source" of that code you will see it has some extensive java loading params etc..
The deal is this, currently you have to go to the site to download the applet (install it on your machine) - and if you look into your Java Console
you will see that the applet loaded and cached fine...
The problem is this - some clients do not have rights to install Java Applets from websites, so i was thinking ... if i can give the necessary jar,cab,etc.. files to the client and the client places the files in a folder on a local network, then on the site i could point to a "local folder" to retrieve all the java information...
here is what i'm thinking:
//--------------------------- existing code start ------------------------------
<applet id=appRemovable class="listappNoMargins" code="com.chatspace.v400321.Chat" archive="cfs40321.jar"
mayscript
width="100%" height="400" codebase="/ChatSpace/Java" name="cs">
<param name="cabbase" value="cs3fu.cab">
<param name="useslibrarycodebase" value="cfs40321.cab">
<param name="useslibrary" value="ChatSpace Full Java Client 4.0.0.321">
<param name="useslibraryversion" value="4,0,0,321">
<param name="namespace" value="nav4">
.// some parameters.. lots of em..
<param name="vdir" value="/clientJava/">
</applet>
//--------------------------------------------- END ------------------------------------
What would i have to change above to make it point to a different location?
such as lets say C:\myApplet\ ?
thnx

MORE INFO:
put it this way , there are 100's of work stations that do not have rights to download/install applets - what needs to happen is for the network admin
to set up a network directory where the applet (and all necessary files)
will be stored, then on my website, i want to point to an applet on THEIR (the client's) network. so they can actually "download" as they have rights to run applications from local network.
is this fairly clear?
thnx

How could we read the XML data from a table using BODS.

Hi Guys,
My requirement is , As the OLTP system consists of a table called person which consists of a column demographics. so how could i read this XML data which is in one column of an SQL table called persons. As this XML data will populate the remaining fields in my target using BODS.
Regards,
Amjad.

Hi Amjad,
I am afraid there ain't any direct method to extract XML field from a data base.
Indirect way could be converting the whole table (instead of one field) into XML format and then extract one field from it!!

How do I access *load paragraph styles* from the styles pallet menu?

Adobe help informs me that I can bring styles from other documents into an existing document by doing this:
"To copy paragraph styles from one publication to another choose Load Paragraph Styles from the Paragraph Styles panel menu."
I do not see any menu in the paragraph style menu. I am in CS5. What am I missing?

I'm sorry, I found it. I had to go back to my G4 and the CS version to see what to do. I did not recognize the small feature on the window yielding the menu.
