URGENT - Applet

Hi there,
I have a problem that I urgently need fixed. I have an applet which runs fine on my local machine i.e. using localhost. But when I connect to the network and try to run it off another machine the screen is grey. The bottom of the screen says �Applet Appletname started�. I am not getting any errors. The following it the HTML file used:

I used the HTML Converter to generate this because I�m using a JApplet(It�s a swing application). I have a folder called Router which contains: Router_Router.html(above) and Router.jar(contains all the class files). I also have the class files all copied into this folder.The applet is called Router.java.
Hope someone can help!
Thanks

I'm also having another problem which might actually be my whole problem - in the applet I want to display an image - I have the following code:
public Image getImage(){
Image img = getToolkit().getImage("C:/road.jpg");
MediaTracker tracker = new MediaTracker(this);
tracker.addImage(img,0);
try{
tracker.waitForID(0);
catch (InterruptedException e){}
return img;
But of course I cant do this ("C:...") when I want to run over the network - so when I use the ip address of my machine when running it in a browser on my local machine - the image does not appear. Where should I put this image - beside the HTML files and the jar?? in the jar? Or will it be relative to where the .java files is? These are seperate to the folder containing the HTML file.

Urgent Applet Modifications

Extremely urgent !!! I like someone to takeover this project or guide me through it - I can compensate if you take it over. I have the source codes but I can't seem to compile them - what IDE can I use to get started.
View this java applet that lets users create and save an image.
I would like users to be able to save a graphic from the current java applet. Then I would like them to be able to put this graphic in one of a few templates and charge them for printing permissions.
So the program must not let the user use "view source" to get the picture or to right click and "save as."(Not very important)
What I am looking for is a new applet that will combine the images with stationary templates and to be able to charge for printing. The background images in the applet also need to be exchanged with new ones.

Here are my Netbeans run / debug messages for my clients source - it says build successful but I never see a running applet or anything. Any advise please - ??? I've changed the sources file path around etc but no luck. I might have to quit this soon.

Urgent Applet Help Needed

Hi All,
I have a following problem. I have included a JTable inside a JScrollPabe in an applet.
However when the web page loads. There is nothing shown. When I tried 'refreshing' the page several times in quick succession , occasionally the contents is shown. What coule be the problem?
Another issue is when I switch to another application, the contents disappear again. How can i fix the contents without it disapperaing when the web page is minimised or has lost focus?
Below is the code for my applet.
import javax.swing.JApplet;
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
import java.io.*;
import java.util.*;
import java.net.*;
import com.sns.legal.lit.applet.*;
public class Simple extends JApplet{
     //private MultiLineTable table = null;
     //private Vector vecResult = null;
     public Simple() {
    public void init() {
    public void start() {
         Object[][] data = new Object[][] {{"first row", "\"I was drunk last night, crawled home across the lawn. By accident I put the car key in the door lock. The house started up. So I figured what the hell, and drove it around the block a few times. I thought I should go park it in the middle of the freeway and yell at everyone to get off my driveway.\"\n                -- Steven Wright"},
                          {"second row", "The most advantageous, pre-eminent thing thou canst do is not to exhibit nor display thyself within the limits of our galaxy, but rather depart instantaneously whence thou even now standest and flee to yet another rotten planet in the universe, if thou canst have the good fortune to find one.\n                -- Carlyle"}};
             Object[] columns = new Object[] {"first column", "fortune cookie"};
             JTable table2 = new JTable(data, columns);
         System.out.println("Start.......................");
         JScrollPane scrollPane = new JScrollPane(table)
         this.getContentPane().add(scrollPane, BorderLayout.CENTER);
         this.setVisible(true);
         System.out.println("End.......................");
    public void stop() {
    public void destroy() {
    public void paint(Graphics g){
    }     Thank alot!

You haven't set the Layout of the getContentPane() to new BorderLayout()
You make the assumption that thats the default layout manager.
Try adding that first.
You may have to add some pack() or doLayout() calls at the end of your start() routine if it still doesn't work.

I run the program using Eclipse; run as> Java applet
and in runs perfectly well. I then tried running it using internet explorer and firefox, but only a gray box appeared and the browser says "applet notinited" and "Loading Java Applet Failed.."
what did i do wrong? any help is really appreciated.. thanks

thank God i already found the cause of the problem..
it's because the application has an ImageIcon which links to a local jpeg file, so perhaps security restriction on the browser doesn't allow my applet to access local file, that's why it fails to load.
either using signed applet (not tested) or removing the picture solved my problem.
thanks anyway :)

Applet does not work with a proxy server.URgent

Hi,
I have an asp page being hosted from a IIS server.
The asp page has an applet which gets data from a server side component which is hosted as a service on the server side.For connection to the server I am using URLConnection object and trying to connect over a TCP connection.
The problem occurs when I use an proxy in the middle.
I have changed the browser settings to include the proxy.
The following is the error I recieve:

// is = new DataInputStream(urlconnection.getInputStream());
     System.out.println(urlconnection.getInputStream());
is = new DataInputStream(urlconnection.getInputStream());
The exact place where I get the error is whn i call URLConnection.openInputStream().
Usually this error comes with a malformed URL.But the same code words without a proxy.Also I am not making any changes to my code in both scenarios that is with or without proxy.
Please help.This is urgent and a showstopper

Thanks for your nice solution, but unfortunatelly it does not work with lines longer than 100 chars with Netscape. It works fine with IE and appletviewer too.
Example:
I use this code:
try {
            URL url = new URL(protocol,hostName,portNumber,URLstring);
            InputStream in = url.openStream();
            BufferedInputStream bis = new BufferedInputStream(in);
            StringBuffer input = new StringBuffer(60);
            int c;
            while ((c = bis.read()) != -1){
                System.out.print((char)c);
                input.append((char)c);
            bis.close();
            dataFromServer = input.toString();
        catch(Exception ex) {
            ex.printStackTrace();
        }I use input file test.html with exactly 100 chars ('a')

I dont know which .jar file to archive (i tried xalan,crimson, jaxp
but which of no use). I was surprised why the security Exception is
thrown , when parsing.
I have not accessed the System files!( but it searches for
jaxp.properties file!). I think the jar file is not downloaded. How to
verify that it is downloaded in applet?
The above code is only for sample.
If anybody who knows how to correct it please mail me at:
"[email protected]" with corrected code. I want this very
urgently.
Help meeeeeeeeeeeeeeeeeeee!!!!!
Prasanna.

Have you found the answer to this problem? I am having a similar problem when running the parser in an ActiveX Bean.
THanks

Please Urgent sound applet in jsp problem

Hi please any body hekp me urgently.
I have a problem while playing a sound applet in the jsp file the error is class not found.
My applet class file is in the com.mypack.common
its code is
public class PlayErrorSoundApplet extends Applet
public PlayErrorSoundApplet()
public void init()
public void playSound()
String soundObj = getParameter("soundObj");
AudioClip sound = getAudioClip(getDocumentBase(), "success.wav");
sound.play();
in the jsp i have written the code like this
<applet codebase="com.mypack.common" code="PlayErrorSoundApplet.class" name="soundApplet" width="0" height="0">
<param name="soundObj" value="error.wav">
</applet>
In the applet console i got class not found error.
please help me .....advanced thanks......

actually, codbase is a directory. so
<applet codebase="com/mypack/common" code="PlayErrorSoundApplet.class" name="soundApplet" width="0" height="0">
<param name="soundObj" value="error.wav">
</applet>this means you have something like
pacakge com.mypack.common
public class PlayErrorSoundApplet {
Make sure to put the html file in the root directory of the package structure
/myhtmlfile.html
   /com
      /mypack

Problem on loading applet netscape4.73 in macos9 very urgent pls help me

Hello,
Problems on loading applet in Netscape4.73(jre1.1.5) AppleMac OS-9.
when i try to load applet of size ~ 200kb in Netscape 4.73 AppleMac os9, then browser abruptly closing with the AppleMac os error message :- the Applicarion " Netscape Communicator " has unexpectedly quit because an error of type 2 occured. And then asking for system restart.
Since i am new to the AppleMac environment i cant adjust the settings please help me to overcome the problem. Its Very urgent and i am in great hurry pls.
thanks in advance.
Rao. V.N.

Hi Rao,
I'm not a mac-os specialist (even I had some business with mac !!), and it is very difficult speaking in blind, but I have severals questions that may help you.
- Did you try you applet in other AppleMac plateform ?
- Does your applet work fine in other browser/plateform ?
- Does a small applet work fine on this plateform with this browser ?
- Does you applet contains instructions like System.exit, System.* or try to access (read or write) to local files ?
Otherelse it is possible you have problem with your jre config, try to configure your plugin with command like : -Xmx64m -Xms16m
(These commands tell the plugin to use at least 16 Mo memory and 64 Mo for the maximum see : http://java.sun.com/docs/hotspot/gc/)
Hope that will help you

Urgent : store and retrieve image to oracle database thru applet

hi all
i want the code sample for storing the image to oracle database
development enviornment:
server : oracle 9i , apache web server
client : ie6 browser
i am connecting to oracle database thru applet using oracle jdbc thin driver
can anyone give me details about storing image to db
1) what datatype should be used in table for image?
2) my image files are on client machine... can i directly read those files from browser or first i have to copy those files to server?
3) .gif files will do or what should be the fileformat?
4) java code to store it to database (i am using jdk1.3)
5) how to retrieve it back from database and display it in awt panel ?
its very urgent ...
i am doing some r&d and trying to do using blob....
but it will take some time ...
i will really be thankful if someone sends detail code....
thankx in advance ....

Hi,
The code below might answer few of your questions.
There is a restrcition on size of image, it must be less than 4KB.
//Code to insert image in database
//mytable is the table name that contains two fields in databse:name,image of type varchar and blob
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con =null ;
Statement stmt =null ;
con =DriverManager.getConnection ("jdbc:oracle:thin:@<hostname>:1521:orclsid", "system","manager");
PreparedStatement preparedStatement = con.prepareStatement("insert into mytable (name,image) values (?,?)");
preparedStatement.setString(1,"Amol");
InputStream inputStream = new BufferedInputStream(new FileInputStream("C:\\WINNT\\Temp\\netscape\\images\\menubg.jpg"));
preparedStatement.setBinaryStream(2, inputStream, inputStream.available());
preparedStatement.executeUpdate();
preparedStatement.close();
inputStream.close(); To retrieve image,here is the snippet
ResultSet resultSet = stmt.executeQuery("select image from mytable'");
if (resultSet.next())
byte[] image1 = resultSet.getBytes("image");
FileOutputStream fos=new FileOutputStream("c://splash11.jpg"); //will retrieve bytes and create a file
//by the name specified
fos.write(image1);
-Amol

**URGENT : signed applet still doesn't get full permissions**

I've bought a Microsoft Authenticode certificate with which I signed a CAB file containing my class files...
On a client machine, the browser detects security stuff but even when one acknowledges, the applet still doesn't get the permission, for instance, to open a directory for reading... a SecurityException is thrown as if the applet was not signed.
Have I forgotten something or did another one wrong ?? Must I set the Security Manager to null ????
It's really urgent, so please reply asap !!!
Thanks,
R�gis Kuckaertz

Just signing the applet doesn't give it any permissions. You have to assert whatever permissions you want. For example:
import com.ms.security.*; // need dummy classes to compile for non-MS
// check if we are in the MS JVM
if (Class.forName("com.ms.security.PolicyEngine") != null)
    // Assert all Permissions
    PolicyEngine.assertPermission(PermissionID.SYSTEM);
catch (Throwable cnfe)
    System.out.println("Microsoft JVM permissions not asserted.");
    System.out.println(cnfe.getMessage());
}

Pls answer my three questions: custom install : web cache applet support: Urgent

we are using 9iAS v 10200 in win2000 server.
Here are my queries:
1: Does 9iAS v 10200 support custom installation ? For example I
want to install only web server,webcache,forms & reports support.
If custom installation of individual components is not available
on v 10200 then in which version it is supported ?
2. whenever I try installs 9iAS v 10200 from network,then after
rebooting(during start of installation)it gives JRE error. is
this a limitation of 9iAS v 10200 ?
3. 9iAS v 10200 web cache does not support applet. In which
version of 9iAS web cache would support applet ?
Its urgent. Thanks in Advance
yogesh

Custom installation is not supported for iAS but we have four
different install types & you can select according to yor need
these are all available with iAS10221 onwards.You check for
installation docs related to the version you are using.

Clustered Servers and Applet (Very URGENT Please)

Hi,
I'm using win2k/CF application server 4.5/IPlanet web server/NN4.79/JRE1.4.1/.
I have an applet in one of my web page which downloads a file from the web server(stored in http://www.abc.net/doc/zip directory on the server).
Now when I run this code on the development server, everything works fine.
But in production environment, we have 3 clustered web servers controlled by a controller (Local Cisco Director) machine. The applet code looks like this:-
strURL = "http://www.abc.net/doc/Zip/"; //the URL from which the zip is to be downloaded. Basically it hits the Controller first
     strZipFileName=getParameter("zipFileName");
     strURL = strURL+strZipFileName;
          //Get Connection to Server and Download the file
          try{
          objUrl = new URL(strURL);
          httpCon = (HttpURLConnection) objUrl.openConnection();
               //DownLoad the File
               InputStream fileInputStrm = httpCon.getInputStream();
               // create a file object which will contain the directory structure to copy in the local machine
               localZipFile = new File(strLocalFilePath+strZipFileName);
               FileOutputStream fileOutStrm = new FileOutputStream(localZipFile);
               int ch;
          while ((ch = fileInputStrm.read()) != -1) {
                    fileOutStrm.write(ch);
               // Close the InputStream, HTTP connection , File stream
          fileInputStrm.close();
          httpCon.disconnect();
          fileOutStrm.close();
Now when the home page of the site is loaded it makes the connection and controller redirects this request to one of the web servers (say 1) which is least loaded.
Now when the applet is loaded, the new connection is established to the controller and it may redirect the request to any one of the 3 web servers (not necessarily to 1 which is required). Now sometimes it hits the right web server on which the required zip file is stored, and sometimes it doesn't hit the correct server.
Any clue what we can do in this scenario so that the applet downloads the correct file from the right server?
Please help it is very urgent....
Thanks

Did you ever get a response to this or figure out how to run in a clustered environment? I am now running into the same issue and would be interested in whatever you learned.
